Title: Focus servo mechanism for optical recording and reproducing device
Inventor: WACHI SHIGEAKI
IPC: G02B7/28
Filed: 1986-11-28
Abstract: PURPOSE:To attain recording/reproduction of stable information with high accuracy by providing a bias circuit for focus error signal between a laser beam output means and an amplifier so as to control the bias signal included in the focus error to be constant. CONSTITUTION:A variable bias circuit 5 is provided to the pre-stage of the 1st amplifier 5 controlled by the laser beam means 3 and both the gain of the 1st amplifier 5 and the variable bias circuit 6 are controlled by using a signal proportional to the laser power obtained from the laser beam output means 3. For example, if the laser power for recording is n-times of that at the reproduction, then the gain of the focus servo system is decreased to 1/n and the variable bias circuit 6 is controlled at the same time to increase the DC bias to n-time. Thus, the AC and DC component of the focus error signal are always made constant to obtain the same servo characteristic at recording and reproduction. Thus, the stable recording/reproduction with high accuracy are attained.

Title: Detecting device for unintentional movement of camera
Inventor: YOSHIDA HIDEO
IPC: G03B17/00
Filed: 1990-10-19
Abstract: PURPOSE:To detect an image unintentionally moving when a photographed object moves by outputting the light reception output corresponding to the external intensity from a light receiving means via low-pass filters and a variable-grain amplifier when no distance measurement is performed, and providing a camera unintentional movement detection signal output means, a camera unintentional movement warning means and a camera unintentional movement reporting means. CONSTITUTION:The light reception output corresponding to the external intensity fed from a reference light reception section 5 is sent to a window comparator 16 via low-pass filters LPF 10, 12, a variable-grain amplifier 14 and a lower-limit limiter 15 when the active type distance measurement is not performed. A camera unintentional movement detection signal is outputted each time the frequency component generated by a camera unintentional movement and having the amplitude at the preset level or above is detected, and a camera unintentional movement warning is issued each time the camera shake detection signal is given during the focus lock. When the camera detection signal is given while a shutter is opened, a camera unintentional movement is reported after exposure is completed. The stability of a camera is promoted prior to photographing for the contribution to prevent the blurring of a photographed picture.

Filed: 1990-10-19
Abstract: PURPOSE:To reduce an offset by compensating it automatically by providing two light receiving elements and a third arithmetic circuit to calculate the difference of the outputs of a first and a second arithmetic circuits. CONSTITUTION:Two light signals incident to a photodetector 1 are converted into electric signals by the light receiving elements 2a and 2b, and are amplified by phase inverting type pre-amplifiers 3a and 3b, and the outputs of the circuits 3a and 3b are subtracted by the arithmetic circuit 4. Besides, the output peak values of the circuits 3a and 3b are detected and held by peak hold circuits 5a and 5b, and the outputs of the circuits 5a and 5b are subtracted by the arithmetic circuit 6, and further, the outputs of the circuits 4 and 6 are subtracted by the arithmetic circuit 8. Thus, an offset component remaining in the difference of the light signal outputs is removed by subtracting the difference of the non-signal outputs of the light receiving elements 2a, 2b from the difference of the light signal outputs of the light receiving elements 2a, 2b.

Title: Semiconductor light emitting device
Inventor: YAMAMOTO MASAHIRO
IPC: H01L33/04
Filed: 1998-10-06
Abstract: PROBLEM TO BE SOLVED: To obtain a structure for long wavelength and enable a light emitting device of low operational voltage by providing a structure wherein a compound containing a specific element in semiconductor is used for a superlattice well or a barrier layer. SOLUTION: Since sapphire, for example, is used for a board, a lamination structure formed thereon has a compound containing P or As of hexagonal system in a semiconductor lattice well or a barrier. Furthermore, an InGaN/ InGaP quantum well layer which becomes a light emitting layer also has a hexagonal system structure. Since a hexagonal system InGaAlNAsP thin film is a compound of direct transition type in a thin region, highly effective light emission or laser oscillation is realized. Furthermore, since P is incorporated, emission of light with a long wavelength is possible and emission of green light which has been extremely difficult in the InGaAlN system alone, or light emission and laser oscillation at still longer wavelengths are possible. Furthermore, enough refractive index distribution is possible and mode control is also possible.

Abstract: PURPOSE:To obtain a high speed and compact neural net of a large scale by providing a communication means between two networks which perform the forward and backward calculations respectively. CONSTITUTION:The calculation units 120F and 121F form a forward network which performs a forward operation, and the calculation units 120B and 121B form a backward network which performs a backward operation respectively. A means is added to carry out the mutual communication between both networks. Each network holds the weight value for the benefit of the parallel calculations of each network. As a result, the same weight is held double and this double holding of the same weight value is corrected by each network. The corrected results are equal to each other. Thus a high-speed neural network of a large scale is obtained in a compact size.

Abstract: PURPOSE: To make an STM/ATM exchange low in cost and small in scale by applying time division multiplex processing to data sent from a fixed path and outputting the resulting data to an ATM highway so as to provide the technology realizing a connection section without use of a time switch and a spatial switch. CONSTITUTION: In the case of reception of data from an STM highway, a write control section 2b of a data distribution means 2 writes data to a memory 2a. Then a read control means 2c reads a signal written in the memory 2a according to a path selection signal outputted from a path selection signal generating section 2d and outputs the signal to an optional fixed path. Furthermore, an output section 6 accommodating plural fixed paths allows a multiplexer means 3 to apply time division multiplex processing to a signal group sent from the plural fixed paths and to output the resulting signal to the ATM highway. Thus, a connection part 1 is formed by the fixed paths to make the exchange small in scale and low in cost.
