Title: Servo signal detector of optical recording and reproducing device
Inventor: SUETSUGU TOSHIO
IPC: G11B7/09
Filed: 1984-09-07
Abstract: PURPOSE:To attain the stable working of an AGC (automatic gain control) circuit regardless of temperature changes by giving the current amplification to the output of each 2-split photodetector for servo control of a pickup coil, etc. and using the difference and sum outputs of these photodetectors to form an AGC circuit. CONSTITUTION:In a reproduction mode a 4-split photodetector 11 receives the reflected light from a disk and uses two of four divided outputs to the control signals to undergo current amplification through current amplifier circuits 13a and 13b. The drifts if produced at the input stages of both circuits 13a and 13b are never amplified. Then a differential amplifier circuit 14, a sum amplifier circuit 15 and an AGC circuit 16 of the following stages are actuated regardless of temperature changes. Then the correct servo control is secured with a stop- down lens stored in a pickup coil 17. While the other two divided outputs are used for detection of RF signals and delivered by voltage feedback resistances 8a and 8b and a signal amplifier circuit 12. In such a way, an AGG circuit can be operated with high stability regardless of temperature changes.

Title: Surface defect detection
Inventor: ABE YUTAKA
IPC: G01N21/89
Filed: 1980-12-29
Abstract: PURPOSE:To achieve automatic detection of defects on the surface of an object accurately by converting signals of beam received into a binary signal according to which a pulse signal with a fixed width is made and then, synchronizing the falling edge of the signal with the falling edge of an address clock pulse. CONSTITUTION:An address clock (a) is generated to divide into numerous address segments a section for one scanning widthwise on the surface of an object such as plate material. A receiving element is provided to obtain a signal (b) of beam received. This signal (b) is converted into a binary signal (c) with a slice level L1. Furthermore, the signal (c) is converted into a pulse signal (d) with a fixed width in synchronization with the leading edge of the binary signal. For registration of the pulse signal (d) into individual register bits 71, 72... of a memory element 7, the falling edge thereof (d) with a fixed width is synchronized with the falling edge of the address clock (a). When the pulse signals (d) with a fixed width continue, the falling edge signal of the address clock (a) will be cancelled. Thus, they are registered into the register bits at the instant when the output pulse signals with a fixed width fall.

Title: Camera system
Inventor: ISHIMURA TOSHIHIKO
IPC: G03B13/36
Filed: 1989-07-19
Abstract: PURPOSE:To eliminate such a trouble that a controlled photometric value is calculated, and shutter speed and diaphragm are stop value according to data on incorrect picture magnifications by considering a picture magnification in calculating the controlled photometric value only when a focused condition is attained when a lens driving stop means is operated. CONSTITUTION:If the lens driving stop means M6 is operated when a focal point detecting means M2 decides focusing, that is translated into that a photographing main object intended by a photographer coincides an object to be focused, therefore a selecting means M7 selects a 1st photometric value determining means M51 calculat ing a photometric value considering the magnification of a photographed picture. On the other hand, when the lens driving stop means M6 is operated without deciding a focused condition, the intended photographing object may be different from the object caught by an AF function, therefore a 2nd photometric value determining means M52 is selected to determine a controlled photometric value. In such a manner exposure against a photographer's intention, which is created by calculating the picture magnifi cation with an object other than the main object focused and further calculating a multipoint photometric value and a controlled photometric value based on the calcu lated magnification, can be prevented.

IPC: G01R33/12
Filed: 1987-07-28
Abstract: PURPOSE:To improve the accuracy of iron loss measurement by clamping an iron plate to be measured between an exciting coil and a secondary coil and arranging three H coils fixedly. CONSTITUTION:H Coils 111 and 112 are fixedly arranged between the iron plate 1 to be measured and the secondary coil 3 at proper intervals. An H coil 113 is fixedly arranged between the iron plate 1 to be measured and exciting coil 2 at proper intervals. The output signals H1, H2, and H3 of those H coils 111, 112, and 113 are led to and processed by an arithmetic means 16 and the intensity of surface magnetic force at the iron plate position is inputted to an iron loss arithmetic means 12. The iron loss arithmetic means 12 calculates the iron loss of an iron plate which is not measured continuously from a specific expression based on the output signal of the arithmetic means 16, information from an excitation control means 10, and information regarding plate thickness from the iron loss arithmetic means 13. Thus, the intensity of a true magnetic field applied to the iron plate can be calculated even when the magnetic field becomes irregular owing to the distances between the iron plate 1 to be measured and H coils 111, 112 and 113.

Filed: 1990-07-16
Abstract: PURPOSE:To increase dielectric strength in the reverse direction, and to eliminate the parasitic movement by forming a high-concentration P-type diffusion layer region to wrap the first low-concentration N-type epitaxial layer, and then by forming the second N-type epitaxial layer to wrap the P-type diffusion region, electrically connecting, and making it into an anode. CONSTITUTION:By connecting a P-type diffusion region 16 with an N-type diffusion region 17, a wiring electrode 19 is made. By connecting a N-type diffusion region 18 with a wiring region 20, a cathode electrode is made. The dielectric strength of a diode equals to the dielectric strength of PN junction of an N-type diffusion epitaxial layer 14, a P-type furied diffusion region 11, and the P-type diffusion region 16. When a diode is made to move to the forward direction, most of electrons are injected from the N-type epitaxial layer 14 in the highly concentrated P-type buried diffusion region 11, and in the P-type diffusion region 16. These electrons are re-coupled there, and are eliminated, and then they make anode current. It never occurs that the electric current flowing in a diode generates the parasitic effect of flowing into other portions.

Title: Transmission controlling device for continuously variable transmission
Inventor: NARITA YASUSHI
IPC: F16H9/00
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To inhibit an influence due to an error of an observer output and to enhance an accuracy of a transmission control by being provided with a control changing means forbidding a compensation by a condition presuming means until a progress time exceeds a predetermined value and a control condition judging means judges a feedback controllable operation condition. SOLUTION: A predetermined value judging a progress time from a reset is previously set to a time presumed to that an output gain is converged. When an observer flag becomes 1, it is presumed that an output of a condition presuming observer 72 is converged and it is judged whether or not a state is a feedback controllable state. In the case where the state is not a feedback controllable state, an integration gain c0, and a differential gain are set to 0 and a proportion gain c1 is set to 1. When the differential gain is 0, the output of the condition presuming observer 72 also becomes 0 and it is forbidden that a control command value (u) is compensated. Thereby, it is certainly prevented that a feedback control is carried out at a state including an error in the output of a differential filter and an accuracy of a transmission control can be enhanced.
