Title: Signal level detection circuit
Inventor: IKEGAMI ICHIROU
IPC: G01R19/165
Filed: 1978-12-26
Abstract: PURPOSE: To accurately detect the level of an input signal, by obtaining a stable level output which correlates to the level of the input signal and is not affected by temperature.  
     CONSTITUTION: Although the emitter voltage of a transistor 26 depends on temperatures 16, 17 and 14, 15 are not unbalanced to each other. Since the forward voltage of a diode 34 has a negative temperature coefficient, the base bias of transistors 10, 11 decreases with the rise in the temperature and increases with the fall in the temperature. Thus, the collector current of the differential amplifiers increases and the collector current of transistors 15, 17 decreases according as the temperature rises. As a result, a level output can be kept constant at a prescribed input level regardless of the temperature.

Abstract: PURPOSE:To manufacture the title FET in high gain at abated noise while weakening source resistance and increasing gm by a method wherein an active layer is formed on a semiconductor substrate so as to be gradually thinned as the active layer approaches from a source electrode to a drain electrode by selective ion implantation and annealing processes. CONSTITUTION:An active layer 18 is formed on a semiconductor substrate so as to be gradually thinned as the layer 18 approaches from a source electrode 20S to a drain electrode 20D by selective ion implantation and annealing processes. For example, a silicon nitride film 31 is formed on the channel part of a GaAs substrate so as to become thicker as the film 31 approaches form the source electrode 20S to the drain electrode 20D while Si<+> ion 17 is implanted in resist opening parts in the assumed source-channel-drain formation regions of FET using resist films 32 as masks. Finally, after removing the silicon nitride film 31 in the channel part, the resist opening parts are made in the assumed source/drain formation regions and then Si<+> ion is implanted in the source and drain parts so that n<+> ion implanted active layers 19 may be formed to be activated by annealing process after removing the resist.

Title: Electrode substrate for display device and its production
Inventor: ITO NOBUYUKI
IPC: G02F1/1343
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To provide an electrode substrate which is free from disconnection and leakage and a process for producing such electrode substrate. SOLUTION: Plural transparent electrodes 22-1 to 22-8 are formed in parallel at the same length on the transparent glass substrate and are so arranged that every other one ends are made flush with each other. While the one-side ends of the transparent electrodes 22-1 to 22-7 of the odd number place are shorted by a conductive paste 41, the one side ends of the transparent electrodes 22-2 to 22-8 of the even number place are shorted by the conductive paste 42. A DC voltage is impressed between the conductive pastes 41 and 42. Leak inspection may be easily carried out by investigating the presence or absence of the conduction between the conductive pastes 41 and 42. Shorting parts S formed between part of the transparent electrodes (for example, transparent electrodes 22-6, 22-7) are impressed with the voltage across these parts and current flows therein, by which these parts are burnt. There is, therefore, no need for detecting the leaking point and the leak correction may be made simultaneously with the leak inspection.

Abstract: PURPOSE:To enforce an inexpensive construction work and to prevent a wide range lawn from being damaged by running a main body by two back and forth wheels by controlling the steering angle of a steering wheel so that the main body may not fall according to the inclined angle determined by an in clined angle calculating device. CONSTITUTION:A main body runs by the two wheels of a drive wheel 3 and a coupled driving wheel 26. When the main body is inclined, a gyro sensor 10 detects the inclined angle and a steering wheel control circuit 19 rotates a steering wheel 26 according to the inclination and corrects the inclination of the main body. When the number of rotation of a driving motor 2 or running speed is below a prescribed value, the main body is thrown out of balance because it runs by two wheels and has the possibility of falling down in either way of left and right sides. Therefore, when the running speed becomes below the prescribed value, an auxiliary wheel 11 is controlled to be put out by an auxiliary wheel putting in and out circuit 22. As the main body runs by two wheels, it can be done by a running route, the enforcement expense of the construction work is inexpensive and a wide range lawn can be prevented from being damaged.

Abstract: PURPOSE:To clearly discriminate both subscripts by displaying the lowest line or the uppermost line of a mathematical expression inputted, respectively by aligning it with a prescribed line or its lower line, at the time of inputting the mathematical expression as the subscript of the upper side or the lower side. CONSTITUTION:In the case of a regular expression, it is displayed by aligning the center of the expression. However, in the upper and the lower subscripts, when the mathematical expression being the subscript is displayed by aligning the center in a head position of the respective subscripts in the same way as the foregoing, the subscript of the upper side and the subscript of the lower side are mixed, both of them are not discriminated, and also, these subscripts and the next expression come not to be discriminated. In order to cope therewith, in the subscript of the upper side, the lowest line for constituting the subscript is displayed by always aligning it with a line of a head position (in this example, the next one on the right side of the upper part of a vertical bar) of the subscript of the upper side. Also, in the subscript of the lower side, the upper line of the expression for constituting the subscript if displayed by always aligning it with a line of a head position of the subscript of the lower side. In such a way, a space line of one line exists between the upper and the lower subscripts, therefore, it does not occur that the upper and the lower subscripts are mixed.

Title: Reflection type light modulator and electric field measuring device
Inventor: TAKEDA YASUHIKO
IPC: G01R15/24
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To easily utilize a modulaled signal by simple constitution. SOLUTION: This light modulator is formed into structure vapordeposited with a double refraction film 72 to be sandwiched, for example, between an end face of a substarte 32 having optical anisotropy and a reflection film 74. The double refraction film 72 functions as a 1/4 wavelength plate. In the reflection type light modulator, a fluctuation range of modulation efficiency is within a practical use range, even in the case where 5% of error exists in a phase difference by the 1/4 wavelength plate, when a polarization condition is changed in an incident portion to the reflection type light modulator having the 1/4 wavelength plate. The reflection type light modulator is composed thereby using an inexpensive single mode fiber, without using a polarization plane conserving fiber.

Title: Forming device for emission tube for electric-discharge lamp
Inventor: YADA MASAAKI
IPC: H01J9/24
Filed: 1981-10-19
Abstract: PURPOSE:To enable even an emission tube with configurational deformations to be formed into an emission tube with a high dimensional accuracy by supporting and rotating the emission tube, which is to be formed, inside a sealed case, irradiating a laser beam on the tube, and changing the internal pressure of the sealed case. CONSTITUTION:A laser beam 23 discharged from a laser oscillating tube 22 is irradiated through a rotary reflection mirror 24 upon the wall of an emission tube (p) to be formed. when the internal pressure of a sealed case 7 is reduced to a given pressure by exhaustion, a controller 32 gives a switching command to a driving device 35, and the rotation angle (theta) of the mirror 24 is reduced in such a manner that only the vicinity of the sealing part is irradiated by the beam 23. At the same time, the controller 32 gives a valve controller 31 a command which makes flow-rate controlling valves 18 and 20 to be opened and closed alternately. Therefore, the internal pressure of the case 7 changes according to the internal pressure of the emission tube (P). When the wall of the tube (P) expands and contracts repeatedly due to the difference between the internal pressure and the external pressure of the tube (P), the thickness of concave and convex parts developing on the wall of the tube (P) becomes almost equal to that of the other parts, and the wall of the tube (P) becomes smooth.

Abstract: PURPOSE:To raise the accuracy of inspection by providing a set pressure change-over device that is able to regulate the set pressures of a pressure reducing device and pressure relief valve respectively to a first set pressure that is ordinarily used and second set pressure for water pressure test. CONSTITUTION:The pressure reduction given by a pressure reducing valve 5 is carried out by regulating the degree of valve opening of a disc 10 that is made by balance between the secondary water pressure that is received on the lower section of a diaphragm 12 and the load of a pressure regulating spring 13 that is given from the upper section. At the time of manufactureing the pressure reducing valve 5 the pin 18 of a second pressure regulating screw 17 is raised until is hits a first pressure regulating screw 16, and the first pressure regulating screw 16 is rotated to make the secondary pressure which is usually used come to about 0.85kg per cm<2> and the spring load of the pressure regulatinf spring 13 is given minute adjustment to set it to a first set pressure. And at the water pressure test after the construction work is completed the second pressure regulating screw 17 is rotated until it hits the first pressure regulating screw 16 to make the spring load stronger and it becomes equal to a second set pressure of about 3kg/cm<2>. In other words the second pressure regulating screw 17 becomes a means to switch the set pressure.
