Title: Distance measuring equipment
Inventor: ITO HIDEHO
IPC: G01C3/06
Filed: 1995-09-07
Abstract: PROBLEM TO BE SOLVED: To suppress noise voltage by detecting the photocurrent of steady light component with high accuracy thereby limiting the feedback regulation range. SOLUTION: A reference current being fed from a constant current supply 29 is amplified by means of a transistor 28 having transistor characteristics identical to those of a transistor 10 for amplifying the photocurrent of signal light component, regardless of the variation of environment. The reference current is converted into a voltage using a diode 27 having diode characteristic identical those of a diode 11 connected between the collector of transistor 10 and the current supply 29 and connected between the collector of transistor 28 and the current supply 29. A decision is made whether the current flowing to the base of transistor 10 exceeds a predetermined level by comparing the voltage drop between diodes 11 and 27 by means of a comparator 26.

Title: Pickup for optical disk
Inventor: SUNAKAWA HIROSHI
IPC: G11B7/1245
Filed: 1985-10-16
Abstract: PURPOSE:To reduce the size and weight of the titled pickup for optical disk by using a means which produces the surface acoustic wave through an optical waveguide to deflect the waveguide light, a tracking error detecting circuit, and a control circuit for a surface acoustic wave generating means respectively. CONSTITUTION:An interdigital transducer IDT 29, for example, is used as a surface acoustic wave generating means. When the frequency of a surface acoustic wave 28 produced by the IDT 29 is changed, the deflecting angle of the waveguide light 24' which is deflected by the surface acoustic wave is changed. Thus the position of the light radiated from a condensing diffraction grating 27 is changed and then the light illuminating position is changed on the surface of an optical disk 40. Therefore the tracking control is possible by changing the frequency of the surface acoustic wave in response to the tracking error signal and then changing the light illuminating position. Furthermore the surface acoustic wave generating means like an IDT, etc. can be set on an optical waveguide 22. Thus a miniaturized pickup for optical disk is obtained.

CONSTITUTION:An element isolation insulating layer 22 is formed on a semiconductor layer 21 made of n-type silicon by selectively oxidizing the surface. Next, at a place which was not oxidized a tungsten silicide layer 23 is formed as a diffusion absorbing layer having conductivity by a chemical growth method. After this, an insulating layer 25 is formed on a base drawing out electrode 24, and then the tungsten silicide layer 23, the base drawing-out electrode 24 and the insulating layer 25 are removed partially by etching so as to form a base window 20. In the transistor which is formed by such a process, an external base region 28 can be shallowed greatly by having interposed the tungsten silicide layer 23, and the base drawing-out resistance and the capacity can be made small.

Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption by making the area of each transparent electrode small going toward the peripheral part of a display screen from its center part, while each line electrode is composed of a transparent electrode for discharge and a bus electrode to supply a voltage to the transparent electrode. SOLUTION: A blue discharge cell CB equipped with a line electrode X and Y, a green discharge cell CG and a red discharge cell CR are arranged in a matrix form in a PDP. The areas of transparent electrodes YTR and XTR, formed in each discharge cell gradually, becomes smaller going toward the peripheral part of a display screen from its center part. A method for making the areas of the transparent electrodes YTR and XTR small is that an electrode width W1 at a narrow width part (a), an electrode width W2 at a wide width part (b) and a discharge gap G are set severally as fixed width, and an electrode length L2 at the wide width part (b) is shortened while an electrode length L1 at the narrow width part (a) is lengthened, for instance.  If the areas of the transparent electrodes YTR and XTR are made gradually smaller, power consumption is reduced by an amount corresponding to the reduction of the area of the transparent electrode as a resistor.

Filed: 1988-09-16
Abstract: PURPOSE:To make it possible to display an accident of leak occurrence with a very simple structure by installing a leak display section at a moving piece integrally sliding with a plunger which cuts off a contact section as it slides attracted by a trip coil when a leak takes place and making the leak display section to be opposed against a display window as a result from the sliding of a moving piece when a leak take place. CONSTITUTION:When a leak takes place, a trip coil 3 is excited by a leak detection signal given from a leak detection section and a plunger 5 is attracted to slide. A switching body 14 moves interlocked with the sliding of the plunger 5 to cut off a contact section 13. And the moving piece 5 slides integrally with the plunger 5 for a leak display section 20 installed at the moving piece 12 to be opposed against display window 19 of the case. Further, the switching body 14 moves to a position where a return operation of the moving piece 6 is restricted, so that even if the excitation of the trip coil 3 is released, the reset operation of the plunger 5 and the moving piece 6 is restricted. Thereby, at the time when a leak takes place, it is possible to keep the leak display section 20 under such a condition that the section 20 is opposed to the display window 19 and also to certainly display an accident of leak occurrence.
