Abstract: PURPOSE: To reduce the number of test data patterns to be prepared beforehand by inputting one test data pattern into a flip flop group of a test circuit being gradually disintegrated once it is set into a shift register.  
     CONSTITUTION: N pieces of input test data D 1 , D 2 ... are inputted into the shift register 2 and the data memorized at the top stage are gradually set into respective flip flops selected through a scan-in terminal SI of the test circuit 1. The selection of the respective flip flops is performed with the address counter 3. The results of the computation set into the respective flip flops are gradually transferred to the shift register 2 which transmits the resuts Q 1 , Q 2 ...Q n  at a time. The input test data D 1 ', D 2 ' ...D n ' are applied direct into an input terminal CI of the test circuit 1 and the results of the computation Q 1 ', Q 2 '...Q n ' are outputted from an output terminal CO. Based on these data, the test is executed.

Title: Magnetic card adjusting system
Inventor: TAKIGUCHI KIYOAKI
IPC: G11B19/00
Filed: 1989-04-14
Abstract: PURPOSE:To prevent a forged magnetic card from being used by deciding forged card when the value of data obtained by inspecting the magnetic characteristics of the magnetic recording part of a magnetic card to be used prior to the execution of price adjustment is different from the value of reference data. CONSTITUTION:When a magnetic card is inserted into a card insertion port 10, a control circuit 50 reads out data written in a magnetic stripe, temporarily erasing the data, writes the test data of a fixed level, erases the test data, reads out the erased test data, and stores the level of the reading signal in a memory. A series of processing is executed plural times by changing the level of the erasing signal. Plural data indicating the levels (residual magnetism) of the erased reading signals stored in the memory are compared with previously stored plural reference data, and when both the data are noncoincident, the inserted card is decided to be a forged card. Consequently, the use of the forged magnetic card can be surely suppressed.

IPC: F04D29/00
Filed: 1980-07-14
Abstract: PURPOSE: To reduce the manufacturing cost of a safety guard by forming a large number of cutout arcuate apertures radially extending in a sheet material, leaving a center disc portion therein, and then carrying out extrusion with using an extrusion die, and to maintain a regular quality by eliminating welded portions from the safety guard so as to prevent generation of trembling sounds caused by vibration.  
     CONSTITUTION: A safety guard 7a is composed of louvers 7b which form, as a whole, a generally convex shape but define an inverted concave coned shaoe in the center portion of the safety guard 7a. Moreover, since the safety guard 7a has no welded portion, there is no problem of leaving unwelded portions. Therefore, trembling sounds due to vibration are hard to generate during operation of the blower 4. Further, with this arrangement which can be obtained in such a manner that a large number of arcuate apertures 7d radially extending are formed in a sheet material, leaving a center disc portion therein, and then extrusion is carried out with using an extrusion die 10, the safety guard can be manufactured through less manufacturing proccess steps at reasonable costs.

Title: Semiconductor disk device
Inventor: SUKEGAWA HIROSHI
IPC: G06F3/08
Filed: 1994-05-09
Abstract: PURPOSE:To improve the write access speed to a flush EEPROM. CONSTITUTION:A NAND bus interface 19 receives 16 ready/busy signals from flush EEPROMs 11-1-11-16 independently and manages the operating state of each flush EEPROM. Thus, a flush EEPROM being a write access object is ready without awaiting the end of operation of all the flush EEPROMs 11-1-11-16 and the write access to the flush EEPROM being the write access object is started. Furthermore, since each flush EEPROM is of a command control type in which the write operation is automatically executed, it is possible to make write access to other flush EEPROM while a flush EEPROM is in data write state and then the plural flush EEPROMs are operated in parallel.

Title: Accommodated shape parts supplying device
Inventor: YOSHIDA RIYOUICHI
IPC: B65G43/08
Filed: 1980-07-11
Abstract: PURPOSE: To align and supply a required number of supply parts irrespective of the quantity of such supply parts remaining on a disk by rotating the disk at an optimum rotational frequency depending upon the quantity of such parts remaining on the disk.  
     CONSTITUTION: If a large quantity of supply parts are thrown on a disk 1, the quantity of such parts being moved increases to cause a signal from a sensor 8 to be made greater. Accordingly, an output of a differential arithmetic unit 11 decreases and an output of a motor controller 13 also decreases to reduce rotations of a motor 2 so that the disk 1 rotates at a slower speed and hence the quantity of the parts being moved from the disk 1 to an aligning track 3 is decreased thereby. The rotation of the motor 2 is controlled such that the quantity of the parts being moved actually is equal to a preset optimum quantity of such parts to be moved. Since those parts which are in a regular posture are taken out from an outlet port 6, the supply parts remaining on the disk 1 decreases accordingly and hence the quantity of the supply parts which move to the aligning track 3 also decreases. Accordingly, the signal from the sensor 8 is reduced to increase an output of a differential arithmetic unit 11 so that the motor 2 is accelerated by the motor controller 13 to thus raise the rotational speed of the disk 2.
