Abstract: PURPOSE:To decrease the number of parts without decreasing the accuracy of measurement by discretely processing the outputs from respective photoelectric transducers for a specific range among measuring wavelength regions and collectively processing the outputs from the plural photoelectric transducers for the other regions. CONSTITUTION:The outputs from the photoelectric transducers 13-16-13-24 corresponding to at least 560-590nm wavelength regions of a spectrocolorimeter which divides the reflected light or transmitted light from a material to be measured by a spectroscope and detects the light spactra thereof by plural pieces of the photoelectric transducer 13 installed for each of the prescribed measuring wavelength units are amplified by discrete amplifiers 14 (A6-A14). The outputs from the other wavelength regions are amplified simultaneously for each of the plural outputs by the amplifiers 14 (A1-A5, etc.). The tristimulus value and chromaticity of the object to be measured are calculated by using the discrete multiple value coefft. for the discrete wavelength regions and using the composite multiple value coefft. for the wavelength region combining the plural regions.

Abstract: PURPOSE:To allow a high speed switching and make high withstand voltage, by providing the collector region immediately under an emitter region and on the part contacted with a base region with higher impurity density than in the colletor region thereunder. CONSTITUTION:One conductive type impurity is introduced from the surface into a one conductive type semiconductor substrate 1 serving as a collector region resulting in the formation of a one conductive type additional region 2. As shown in the figure (c), an inverse conductive type base region 3 is formed shallower and wider than the additional region 2, and next as shown in the figure (d), a one conductive emitter region 4 is formed so as to be opposed to the additional region 2 in the base region. Thereafter, as shown in the figure (e), a surface protection film (SiO2 film 5) and each lead-out electrodes (emitter electrode 6 and base electrode 7) are formed so as to protect each junction. A collector electrode 8 is took out from the bottom but can be took out also from the surface. Thus, a switching characteristic at a sufficient high speed and an element at a high withstand voltage are obtained.

Abstract: PURPOSE:To enable recover automatic tuning immediately even the receiver is in a normal reception mode by holding a defeat voltage and error voltage in the same states as a normal tuning state by providing a clamper circuit. CONSTITUTION:While clamper circuit 100 is in operation, the upper limit of the voltage of signal line 9 is clamped to the voltage of connection point 13 and when it increases more, electric current is flowed through transistor TR113 to decrease it down to the voltage of connection point 13; and the lower limit of the voltage of signal line 9 is clamped to the voltage of connection point 12 and when it decreases more, electric current is flowed to diode 115 to increase it up to the voltage of connection point 12. Further, the voltage of signal line 8 is clamped lower than the voltage of connection point 14 and when it increases higher, electric current is flowed to TR114 to decrease it down to the voltage of connection point 14. This low voltage is equivalent to a voltage showing the existence of a synchronizing signal in detecting circuit 6 and even if a defeat voltage showing the nonexistence of the synchronizing signal is outputted from circuit 6, the upper limit of the voltage of signal line 8 is clamped to the voltage of connection point 14.

Title: Mask alignment device
Inventor: NAKAMURA TAKUMA
IPC: H01L21/027
Filed: 1978-10-30
Abstract: PURPOSE: To make it possible to achieve highly precise mask alignment by moving a wafer or mask using a measuring worm type transfer mechanism and arranging it in a line.  
     CONSTITUTION: Applying voltage to a piezoelectric element 62 for a clamp for forward movement on the right to grip a central bar 64 for locomotion, and applying voltage in the shape of waves which increase in tiers to a flexible piezoelectric element 63, the element 63 extends to move the central bar 64 forward on the right. When the applying voltage to the element 63 reaches the highest value within tolerance, voltage is applied to the piezoelectric element 61 for a clamp which grips the central bar 64, then the applying voltage to the element 62 is suspended so that it releases the central bar 64. When the voltage in the shape of waves which decrease in tiers is applied to the element 63, the element 63 contracts to move the central bar 64 again forward on the right. It is also possible that the element moves backward on the left. As the least amount of transference for the wafer or mask can be reduced by interconnecting them to the central bar 64, highly precise mask alignment is possible.

Abstract: PURPOSE:To prevent the variance of a drop voltage obtained in a voltage dropping circuit even if the output voltage of a battery is fluctuated, by setting the charge period in the voltage dropping circuit within the turn-off time of a switching element. CONSTITUTION:When a voltage drop is started, an MOS transistor TR 21 is turned on, and the circuit between the negative pole side of a battery 1 and a terminal 7 is forcibly short-circuited, and the terminal 7 is set to a voltage VSS. At this start time, a switching signal is set to a voltage VCC, and MOS TRs 15, 19, 12, and 14 are turned on. Since two capacitors 5 and 6 are in parallel, they are charged to the voltage VSS. When the switching signal is inputted after the initial state is set in this manner, MOS TRs 11 and 12 and MOS TRs 13 and 14 are turned on and off alternately to obtain the half voltage of VSS at the terminal 7.

Title: Liquid pressure control device for two-system brake circuit
Inventor: MIURA EIJI
IPC: B60T8/26
Filed: 1980-09-26
Abstract: PURPOSE: To compensate reduced braking force owing to failure in one of the systems in a brake circuit by coupling two systems through a coupling member when the pistons of these systems move to a larger scale than a certain allowable value of variation, putting the working pressure balanced during normal condition, and by applying the whole load to one control piston when the other is in trouble.  
     CONSTITUTION: A coupling member 24 is installed in engagement with circumferential grooves 17c of both control pistons 17. Thicknesses of the circumferential grooves 17c and the coupling member 24 are set larger than variation of the control pistons and smaller than the stroke in working. Accordingly, if the pistons make a relative movement exceeding said variation, the coupling member 24 couples the two pistons. Thus, in the event of leakage of liquid pressure at one of the systems, the force of a spring 22 is all applied to the piston in the other system to double the control pressure and thereby to maintain necessary braking force.
