Title: Semiconductor laser
Inventor: UEHARA SHINGO
IPC: H01S5/00
Filed: 1989-10-09
Abstract: PURPOSE:To provide a small high-power laser capable of stable oscillation at a wavelength of about 0.98mum by forming a quantum well structure of an active well layer of InxGa1-xAs and a barrier layer of GaAs or AlyGa1-yAs, where the proportion of indium and the well layer thickness are determined properly. CONSTITUTION:A semiconductor laser has a quantum well structure in which a well layer is sandwiched between barrier layers. The well layer 5 is formed of In0.2Ga0.8As of a 110 thickness. The wavelength of oscillation is about 980nm. More generally, the well layer 5 is formed of 30 to 200 Angstrom  thick InxGa1-xAs, where 0.15<=X<=0.3. In this case, the wavelength of oscillation is about 980+ or -3nm. A contact layer 8 and a clad layer 7 are processed to form a ridge having a thickness of about 3mum. An SiO2 film formed by sputtering is patterned into 3mum-wide stripes, and it is used as a mask to etch the contact layer 8 and clad layer 7 by RIE using BCl3. After the ridge is formed, SiO2 is deposited over the surface, and the SiO2 on the ridge is etched away. Then, a p-electrode 10 of CrAu and an n-electrode 11 of AuGeNi are formed.

Title: Patch possible read-on memory
Inventor: YAMAGA HIROYUKI
IPC: G11C29/04
Filed: 1990-10-02
Abstract: PURPOSE:To facilitate a correction processing when the alteration of the content of ROM in a delivery machine is required by comparing the outputs of patch address selection circuits and the content of a memory address to be accessed and controlling patch data holding circuits and patch address holding circuits. CONSTITUTION:An address holding circuit control line 2b outputted from a control circuit 2 stores a patch address value. Address comparison circuits 61 and 62 compare a patch address selection line 5a outputted from the patch address selection circuits 51-52 with the value of an address bus 10a. The result is informed to a control circuit 2 by a patch area instruction line 6a. When an address except for addresses which are set in the patch address holding circuits 41-48 are read after the setting of writing, all patch area instruction lines 6a being the outputs of the address comparison circuits 61 and 62 show unmatch, the control circuit 2 requests data output to a ROM circuit 3. Thus, the arbitrary address in ROM can be patched. Thus, the correction processing of the content of ROM in the delivery machine can be facilitated.

Title: Logic circuit
Inventor: UMEKI YOSHITAKA
IPC: H03K19/003
Filed: 1985-11-22
Abstract: PURPOSE:To protect an input transistor (TR) by inserting a resistor respectively between a base and an emitter of plural input TRs. CONSTITUTION:Each input terminal is connected to common emitters of the input TRs 9-11 and a comparison TR 12 via resistors 57-59. In opening an input terminal, a base of an input TR reaches an equi-potential to the emitter by a resistor connected between its base and the emitter. Thus, no EB junction reverse voltage is applied to the input TR. Since the base potential of the input TR is lower than a reference voltage 7 by a forward EB junction voltage of the TR 12, it is handled equivalently as logic '0'. Thus, the input TRs are protected.

Abstract: PURPOSE:To enable sealing and positioning to be made with a support member without using an adhesive when fixing an electrostrictive element in a metal case enclosed type piezoelectric actuator by contact bonding with a spring pressure of a metal case. CONSTITUTION:An electrostrictive element 1 is placed at a support member 7a which has a hollow space which is in a circular shape being slightly smaller than an inner periphery of metal members 3 and 6 and is slightly larger than a sectional area of the electrostrictive element and has a material which is made of an insulator, thus enabling an area between the electrostrictive element and the metal members to be sealed. Therefore, since no adhesive is used, stress near an adhesion portion which is generated due to pulse drive or temperature change is eliminated and generation of exfoliation and crack near the adhered part is prevented.

Filed: 1989-10-11
Abstract: PURPOSE:To improve attribute discrimination accuracy by repeating segmentation processing with a circumscribing rectangle detecting means, performing classification with an attribute discriminating means, and unifying a circumscribing rectangle to a block with a character unifying means. CONSTITUTION:The circumscribing rectangle detecting means 31, when optimally binarized image data is inputted, makes the information areas of a field separator, a photograph, a chart, and a character part, etc., in the data into the circumscribing rectangles, and detects the feature of the circumscribing rectangle and that of a binary image in the circumscribing rectangle. After that, the circumscribing rectangle discriminating means 33 discriminates the attribute of the field separator, the photograph, the chart, and the character part, etc., in the information area, and furthermore, automatically sets a unified threshold value from the image obtained by extracting only the character part out of the attribute corresponding to individual document image data. Following that, a character part unifying means 37 unifies the circumscribing rectangle of the character part to a character part block. Thereby, it is possible to obtain an area dividing method for document image with easy selection of the threshold value.
