A practice for applying indicia to the surface of a precious stone wherein a source of laser energy is directed at the stone surface and controlled to inscribe the surface with the desired indicia.

PURPOSE:To ensure safety for the backward motion of a car by taking information about a condition up to a predetermined stop position through a rear side sensor, a car speed sensor and an injection sensor, and making a computer automatically control a car on the information so taken. CONSTITUTION:When a car 10 is driven back and stopped at a position near a stop plate S, an operation switch 23 is ...

PURPOSE:To enable production of two type of batteries, or high capacity battery and long service life battery, without modifying the specification of plate by making constant the filling quantity of paste in yet-formed cathode plate and forming while varying the filling quantity of paste in yet-formed anode plate. CONSTITUTION:Formation is executed while determining the number of sheets such that ...

PURPOSE:To improve the performance of car start by making a speed change smaller when a car is started with an airconditioner operating and controlling engine speed at a high level with a delayed speed change. CONSTITUTION:In speed change control by a control unit 40 for a belt type continuously variable transmission, output signals from each sensor 41-44 are first read in, and actual car speed (i...

PURPOSE:To enable a necessary minimum line pressure level to be kept without necessity for setting target line pressure preliminarily at a high level by correcting the line pressure upward when said pressure under a predetermined condition has fallen below a necessary minimum level due to the effect of oil temperature and the like. CONSTITUTION:In line pressure control by a control unit 70 for a b...

PURPOSE:To ensure the proper control of line pressure by determining a duty ratio on relations between a target line pressure level as electrically calculated and engine speed for the control of a solenoid valve and regulating a line pressure control valve through duty pressure thereby generated. CONSTITUTION:In line pressure control by a control unit 70 for a belt type continuously variable trans...

PURPOSE:To ensure the proper control of line pressure with duty pressure generated through a duty-controlled solenoid valve by smoothing pulsating oil pressure arising from said solenoid valve through an accumulator. CONSTITUTION:A belt type continuously variable transmission 4 is equipped with a secondary cylinder 10 fed with pressurized oil through an oil pump 21 and a primary cylinder 19 fed wi...

PURPOSE:To prevent the poor initial working of hydraulic pressure from a primary cylinder at the time of car start after long rest by introducing temporarily line pressure to said cylinder for a torque converter and thereby filling hydraulic oil in said cylinder. CONSTITUTION:When a belt type continuously variable transmission is controlled, output signals from each sensor 71-74 are first read int...

PURPOSE:To enable acceleration properly while a compressor drive power being compensated for when an accelerator pedal has been stepped down with an airconditioner operating, by controlling a speed change toward an increase in driving power. CONSTITUTION:In the control of a belt type continuously variable transmission, output signals from each sensor 41-44 are first read into a control unit 40, an...

PURPOSE:To make it possible to easily judge whether the state of a living body from which a fluid to be examined is sampled is normal, by storing a measuring date and a measured value is a memory to calculate an average value and displaying the average value as a graph. CONSTITUTION:A display device 3 consisting of a liquid crystal element, a mode change-over switch 4, a measurement/display change...
