Abstract: PURPOSE:To contrive reduction in warpage by a method wherein the title semiconductor substrate is composed of the signal crystal silicon substrate, having a plurality of surface regions separated by grooves, and the III-V compound semiconductor thin layer formed on the surface of the above-mentioned silicon substrate by performing an epitaxial growing method. CONSTITUTION:A III-V compound semiconductor thin layer 3, consisting of gallium, arthenic and the like, is formed on the surface of the silicon substrate 1 having grooves 2 by performing an MBE method or an MOCVD method and the like. As a single crystal compound thin layer is grown on the surface of the silicon substrate 1, the part 5 having the grooves 2 is turned into a specific region, single crystal is not grown thereon, and a polycrystalline part containing a number of defects, cracks and voids is formed. The grating constant between the silicon substrate 1 and the III-V compound semiconductor thin layer and the stress on the part in the vicinity of the junction interface generated by the difference in the coefficient of thermal expansion are alleviated by the defective regions of the III-V compound semiconductor thin layer 3 formed on the groove 2 part, and the warpage on the semiconductor substrate can be reduced.

Title: Automatic fading device
Inventor: KAGECHIKA TAKASHI
IPC: G03B19/18
Filed: 1978-12-01
Abstract: PURPOSE: To make fading time substantially constant by performing fading through utilization of part of an automatic exposure control unit in a cine camera.  
     CONSTITUTION: When a select switch SW 2  is set at fade-in, SW 3  goes ON to let an aperture mechanism be maintained in a closed state. SW 3  is turned OFF by shutter release operation and the aperture mechanism is driven to the open side. Upon lapse of a fixed time after the release operation, a trigger switch SW 4  goes ON, causing a servo meter 7 to be so braked as to become the speed corresponding to the sensitivity of a film. In the state where it nearly coincides with correct exposure aperture value, the braking is released by a time constant circuit 12. As a result of this, the fade-out of the high-luminance object existing in the subject may be smoothly accomplished as well.

IPC: H04N1/40
Filed: 1993-06-21
Abstract: PURPOSE:To keep a solid object original within the depth of field of an image- forming system by reducing the optical path length of a reading optical system from an original placing table to an image sensor, and changing the level of a reading signal when a solid object original reading mode is designated. CONSTITUTION:Parallel flat glass 16 is located at a position deviated from the optical path of the reading optical system in a sheet original reading mode, and design to image-form the image of an original on a platen plane on the image sensor 5 is made. When a solid object reading mode is selected via a user interface 13, a CPU 14 for motor control drives an optical path length change mechanism 15, and inserts the glass 16 to the optical path of the reading optical system. In this way, the optical path from an image-forming lens 4 to a platen 1 can be reduced, and the best focusing plane PB is moved to a position where it is floated by prescribed distance from the surface of the platen 1. Therefore, the depth of field for the solid object original can be increased, thereby, the image can be read with high resolution.

Abstract: PURPOSE:To guarantee rapid and precise measurement of temperature with a low temperature black point furnace by providing the output side of a PID temperature controller with an output detector, a signal inverter, a signal selector, an adder, etc. and switching the positive and negative operation of the controller automatically. CONSTITUTION:The proportional integration/differentiation PID temperature controller 1 sends as output signal S to the output detector 2 in accordance with the measured temperature and the detector 2 outputs the signal S to the heating side at 1/2 full spun or more and to the cooling side at 1/2 full spun or less and a contact signal D at 1/2 full spun. Receiving the signal D, the signal inverter 3a inverts the signal D and outputs the signal S on the heating side and a signal -S on the cooling side. At the input of the signal D, the signal inverter 3b inverts the polarity of a DC power supply 8. The signal selector 4 divides the signal to the summing operational unit 5b on the heating side and the summing operational unit 5a on the cooling side to output the signal, so that the signal is doubly amplified to measure the temperature.

Title: Shuttle motor speed control system
Inventor: ARAGAKI TAKAHIKO
IPC: B41J19/18
Filed: 1989-06-12
Abstract: PURPOSE:To detect the rotating angle of a motor and to designate a rotating speed designated value at each position pulse by counting number of pulses from an encoder coupled directly to a shuttle motor shaft in a shuttle type dot matrix printer. CONSTITUTION:A counted value of position pulses by a position counter 11 is used as an address of a speed designation ROM 12, and its data indicates a speed designated value. When one revolution of a shuttle is equally divided by N as position pulses and an origin pulse is output as the shuttle is located at the leftmost end, the speed designated value can be altered at each revolution of 360/N [degrees] of a motor. On the other hand, the period of the position pulse is measured by a pulse period measuring circuit 13, a difference from the speed designated value is calculated by an error detector 14, input to a pulse width modulator 15, and a chopper drive signal of a pulse width proportional to the difference is generated. When this is input to a driver 16 to drive a shuttle motor 17, the speed of one revolution of the motor can be varied at each time when the position pulse is output at an angle of outputting an origin pulse as an origin.

Title: Image forming device
Inventor: GOTO KOJI
IPC: G03G15/16
Filed: 1987-06-18
Abstract: PURPOSE:To fully lower the surface electric potential of a photosensitive body so as to effective prevent the retransfer and the occurrence of a ghost and to obtain the image of good quality by making the light quantity of transfer pre-exposure more than double quantity of image exposure. CONSTITUTION:In a position before a developed toner image passes a developing position and reaches a transfer charger 7, the surface of the photosensitive body 1 carrying the toner image receives the transfer pre-exposure with a light source 5 so as to destaticize unnecessary charges. Reaching a transfer part providing the transfer charger 7, the toner image is transferred on a transfer material supplied by a carrier path 6. Then the transfer material is separated from the photosensitive body with the action of a separation charger 8 and carried to a fixing part by a carrying member 9. In such a case, the light quantity of the transfer pre-exposure is made more than double quantity of the image exposure. Thus, favorable separation by executing the transfer pre- exposure can be maintained and also the image of good quality can be obtained without causing the ghost.

A control unit (5) is arranged to receive as input signals at least the signal generated by the foot pedal sensor (7) and the signal generated by the speed sensor. The control unit (5) operates with two functions, namely a speed function (HF) which is contingent on the position of the foot pedal, and a base function (GF) for the fuel/air supply to the vehicle motor, this base function being contingent on at least the position of the foot pedal. The control unit (5) controls the supply of fuel/air to the engine of the vehicle in a manner such that as soon as the vehicle speed at the prevailing foot pedal position exceeds the speed stipulated by the speed function (HF) the vehicle speed is regulated down to this stipulated speed, whereas immediately the vehicle speed falls below the speed stipulated by the speed function the fuel/air supply to the engine is controlled in accordance with the base function (GF).
