Title: Electronic parts mounting device
Inventor: AZUMA MASAYUKI
IPC: B23P21/00
Filed: 1991-12-02
Abstract: PURPOSE:To quickly switch two tables to each other so as to reduce vibrations and noise generated when the tables are moved by setting the separation limit and approach limit distances between the tables and providing a control means which outputs an approach or separation commanding signal to a table driving mechanism. CONSTITUTION:The separation limit distance L2 and approach limit distance L1 which is shorter than the distance L2 between two tables 6 and 7 are set and the distance L(t) between the table 7 at a pickup position Q and the other table 6 at a standby position is detected. A control means 30 outputs an approach commanding signal for bringing the table 6 nearer to the table 7 to a table driving mechanism when the distance L(t) is longer than the distance L2 and a separation commanding signal which separates the table 6 from the table 7 to the mechanism when the distance L(t) is shorter than distance L1. Therefore, the tables can be quickly switched to each other and, at the same time, generation of vibrations and noise which are generated when the tables are moved can be reduced.

IPC: C04B35/00
Filed: 1988-12-16
Abstract: PURPOSE:To manufacture the title ZnO varistor within a short time heat treatment with alpha value maintained at the specified level by a method wherein the heat treatment after baking process is executed under pressurized condition while the relation between the pressure and the temperature is set up in the value within specific region. CONSTITUTION:In order to manufacture the title ZnO varistor by wet-mixing zinc oxide as a main component with an additive containing several kinds of oxides in a very small quantity to be baked after granulation and formation with an organic binder added thereto and then further heat-treated, the heat treatment after baking process is executed under pressurized condition while the relation between the pressure and the temperature is set up in the value within a specific region. For example, the heat treatment after the baking process is executed in an autoclave so that the value of temperature and pressure may be contained in the region shaded by oblique lines. Furthermore, since the lower the temperature, the shorter the heat treatment time within this region, it is recommended to set up the temperature not exceeding 500 deg.C and the pressure not exceeding 300 atmospheric pressure in view of the cost installation as well. Through these procedures, the heat treatment time can be cut down with alpha value maintained at the specified level.

Title: Optical sensor
Inventor: ISHIYAMA KENICHI
IPC: G01V8/10
Filed: 1994-12-21
Abstract: PURPOSE: To detect the occurrence of abnormality and the cause and position of the abnormality by providing a comparison means of the output level of a photosensitive diode and a standard signal level. CONSTITUTION: Currents I1, 12 corresponding to a light radiating position and a light amount are output from both ends A1, A2 of a photosensitive diode (PSD) 3. The currents I1, 12 are converted into voltages by the current-voltage converters 41, 42 in a sensor output portion 4. Converted outputs are input to a differential amplifier 43 so as to output the voltage proportional to the difference of the output currents I1, 12. The sensor outputs are sent to an arithmetic processing unit so as to obtain a light radiation position. The outputs of the converters 41, 42 are sent to an adder 51 in a feedback portion 5, and the brightness of an LED 2 is adjusted so that a current sum (I1+I2) becomes constant.  Since the voltage of a point B becomes 0V when the LED 2 is broken down, a high level signal is output from an output terminal T11 at an abnormal time by comparing the same with a standard voltage VR2 through a comparator (a comparison means) 11.

Title: Cryptographic information communication system
Inventor: SHIGEMITSU MINEO
IPC: H04L9/32
Filed: 1987-12-18
Abstract: PURPOSE:To make the decoding of information by a 3rd party difficult by using a recipient name code and a finger print of a recipient at a transmission side, applying cryptographic processing with them, using the recipient name code and the finger print of a recipient, and applying person identification and decoding with them at the reception side. CONSTITUTION:A cryptographic key generating means 2 generates a cryptographic key based on a data specific to a recipient, that is, a finger print code data, a recipient data and communication text. A reception station applies the opposite processing to that of a transmission station, that is, encipherment. In this case, A recipient confirming means 10 receives the finger print of the recipient together with the recipient data at every occasion and confirms whether or not the recipient is correct, and a cryptographic key generating means 13 generates a cryptographic key similarly to the case with a cryptographic key generating means 2 at a transmission station. A cryptographic text decoding means 14 uses a cryptographic key to decode a cryptographic reception text generated from the reception means 7. Thus, the decoding by the 3rd party is prevented by using the finger print at the reception station to confirm the recipient.

Filed: 1990-11-22
Abstract: PURPOSE:To attain optimum smoothing correction and to attain stable print-out at all times by providing a relation revision means which revises the relation between a size and a position of a target print dot and a write pulse signal at any time to the device. CONSTITUTION:A CPU 11 receives a signal from sensors 15-17 via a port 18 to control a register section 19. A MACH section 5 selects any among 16 kinds of correction output patterns #1-#16 in which the size and the position of print dots differ from each other and gives the result to a post-stage register section 19. The register section 19 consists of 16 sets of 16-bit registers corresponding to the 16 kinds of the correction patterns. A data of any registration commanded by the MACH section 5 is transferred further to a post-stage shift register 20, in which the data is converted serially and a write pulse signal is sent. Since the write pulse signal is revised at any time, a picture with high quality is obtained, in which no ruggedness is remarkable.

Abstract: PURPOSE:To minimize the cut width of a recording paper sheet by a method wherein a cutting mechanism part is driven at a timing before a recording sheet is conveyed and conveyance of the sheet is continued again after the passage of it through the cutter mechanism and a moving conveyance passage on which the cut pieces of the recording sheets are dropped is moved aside. CONSTITUTION:A recording sheet 34 is first fed from a roll paper sheet 17 by means of paired paper feed rollers 19 (a and b) and paired conveyance rollers 20 (a and b). Secondly, the forward end of the recording sheet 34 is detected by a sensor 21 and after a lapse of a given time, the roller pairs 19 and 20 are respectively stopped. Subsequently, the forward end of the recording sheet 34 is cut in a strip-form shape by a cutter 22. Simultaneously, a moving conveyance passage 35 is driven and a lower guide 35b is rotated downward around an axis part 36. Further, a fan 23 is run. A cut piece 34a of the recording sheet 34 is then dropped and contained in a receiving box 24. Thereafter, the recording paper sheet 34 is transferred toward a transfer part. This constitution reduces the cut width of the recording sheet 34, saves the wasteful use of the recording paper sheet 34, and reduces the size of the receiving box 24.
