Title: Method and device for correcting positions of die, punch and ram, bending method and bending machine
Inventor: KOYAMA KATSUMI
IPC: B21D5/02
Filed: 1999-07-15
Abstract: PROBLEM TO BE SOLVED: To provide a method and device fore correcting the position of a die, punch and ram, and to provide a bending method and a bending machine by which the accuracy of bending is maintained by directly detecting the variation between the edges of the punch and die due to various factors. SOLUTION: A ram 7 is positioned in a prescribed position before starting the working, a distance is measured with a laser length-measuring device 21 by irradiating a slope face of the die D with a laser beam, and the distance is measured again by shifting the laser beam and irradiating a reflecting surface inside the slit of the die D. After the ram 7 is positioned in the prescribed position after working, the distance to the die D is again measured by the similar manner, and the laser length-measuring device 21 is vertically moved so that the distance to the die D at this time is equalized with the distance before starting the working. The position correction of the ram is calculated from the difference between the distance to the punch P at this time and the distance to the punch P before working, and the position of the ram 7 is corrected.

Abstract: PROBLEM TO BE SOLVED: To mount a photointerrupter along a circuit board, etc., and contrive to miniaturize a device by a method wherein a lead is disposed along a side face of a mold enveloping a light-emitting element and a light-receiving element. SOLUTION: A pair of light-emitting element and light-receiving element is disposed in a state counter to each other in an opening part 8 of a mold 7 having a substantially rectangular shaped section, and a face-mounting type of photointerruptor A1 capable of detecting an object to be detected entering into or exiting from the opening part 8 is constituted. In particular, a slight process is executed in a die used for a formation of the mold 7, and a series of lead accommodation grooves 15 to 18 are formed in a mold side face projecting leads 3 to 6 and a side face adjacent to the same face, and the leads 3 to 6 are bent so as to be accommodated in the lead accommodation grooves 15 to 18, and the leads 3 to 6 are disposed so that the surfaces are substantially flush with a side face of the mold 7 side.

Title: Optical information recording medium
Inventor: HORIE MICHIKAZU
IPC: G11B7/24073
Filed: 1995-08-08
Abstract: PURPOSE: To lessen the deterioration due to many times of repetitive recording by making the track pitch of an area where file management information is recorded wider by 1.05 to 1.5 times the track pitch of another data recording areas. CONSTITUTION: The track pitch of the general user recording region is determined by the optical diffraction limits. In actuality, the track pitch is so selected that the leaking signal quantity from both adjacent tracks adjacent to each other, i.e., crosstalks, attain <=-20dB. On the other hand, the track pitch in the file management information is made wider to 1.05 to 1.5 times the track pitch of the recording region. Such track suffices substantially at <100 tracks. The recording track pitch in the user region is improved just by about 5% if the widening is <1.05 times and, therefore, such widening is undesirable. The difference in the track pitch between the user area and the file management area is so large that a separate track servo circuit is needed if the track pitch is made wider by >=1.5 times and, therefore, such widening is inadequate.

Abstract: PURPOSE:To avoid misprinting, by preliminarily printing a bar code on the rear of a paper, and to automate color printing, by using a printer capable of automatically exchanging a monocolor unit. CONSTITUTION:A bar code 5 printed on the rear 4-2 of a slip 4 provides information to be printed on the face side 4-1 of the slip 4 and color information. The bar code 5 is preliminarily printed by a printer 2 according to instructions from a processor 1. When printing on the face side 4-1 of the slip 4, the printer 2 receives the content of the bar code 5, replaces a monocolor unit 3, if required, and prints on a large number of the slips in a range of printing in monocolor. Such color printing processings are performed in a superimposing manner to obtain a desired slip, as represented by the two slips 4, 4 arranged one above the other in a right upper area. Accordingly, color printing can be totally automated, and the possibility of misprinting can be markedly reduced.

Filed: 1985-09-11
Abstract: PURPOSE:To shorten an interval between a base electrode and an emitter by mesa etching the emitter by means of the second mask formed by the transparent first mask, and forming the base electrode by a lift-off method with the extension of the first mask formed at the time of forming the second mask. CONSTITUTION:With a photoresist 6 as a mask an SiO2 film 5 is etched to sidewisely etch approx. 1mum. Then, with the film 5 as a mask an emitter layer 4 is selectively mesa etched, and AuZn is deposited to form a base electrode 7. Thereafter, the photoresist 6 is removed by a lift-off method, the SiO2 film is then removed, and the emitter layers at both sides of the base electrode are also removed. Since the transparent photoresist 6 of the mask is used, the film 5 can be patterned while confirming the sidewisely etching amount, and since the film 5 is used as a mask in the mesa etching, the sidewise etching does not occur at forward mesa time to control the interval between the base electrode and the emitter with good reproducibility.

Abstract: PURPOSE:To provide a liquid crystal display device whose plural display screens are connected in a direction even other than the laminated direction of an optical fiber sheet in an optical fiber bundle and further which is excellent in the image quality of a synthetic screen. CONSTITUTION:The respective optical fiber bundle parts 3a having respective display element screens to which an input end face 5 is connected are formed so that they are bent in a reverse direction on two lines 8 and 9 of each optical fiber sheet 4 between the input end face 5 and an output end face 6, the two lines 8 and 9 are inclined to the input end face 5, and a separate distance D1 in a direction along the line is kept constant. Thus, the optical fiber bundle parts 3a are formed to overhang in two directions, the laminated direction A of the optical fiber sheet 4 and the arranged direction B of an optical fiber 1 in the optical fiber sheet 4 on the input end face 5 side. Since each optical fiber bundle part 3a is connected on two side surfaces on an overhanging side and an opposite side so that the input end face 5 may be separated, the display element screens in two directions A and B are synthesized.

Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To improve resolution without changing the integrated degree of photodetecting picture elements and to prevent the generation of moire without using the expensive low-pass filter(LPF) of quartz or the like. SOLUTION: Diffraction grating is executed to transparent parallel planar plates 6 arranged while inclined at a prescribed angle to an optical axis 7 between an image to be photographed and a photodetecting part 2 and these parallel planar plates 6 are rotated while inclined at the prescribed angle to the optical axis 7. Therefore, the plural sample points of the image to be photographed are periodically moved and successively detected by one photodetecting element of the photodetecting part 2 so that the resolution can be improved without changing the integration degree of photodetecting picture elements.  At the same time, the light from the sample points is split into 0th- degree diffracted light and 1st-degree diffracted light at the almost equal ratio by the diffraction grating on the parallel planar plates 6 so that the 0th-degree diffracted light and the 1st-degree diffracted light can be canceled for each photodetecting element. Thus, when displaying the detected image signal, the generation of moire can be prevented without using the expensive LPF of quartz or the like.

Abstract: PURPOSE:To ensure turn-off of a photo triac in a photocoupler when a main triac is turned on by inserting an anti-parallel circuit of semiconductor elements in series between the triac and the photo triac. CONSTITUTION:With a signal VIN is inputted, a lightemitting diode 13 of a photocoupler 4 is lighted, a photo triac 14 is turned on and a current ig flows as a gate current of the main triac. Thus, the main triac 7 is triggered and turned on and power is supplied to a load 3 from an AC power supply 2.
