Title: Reader/writer for card
Inventor: KIMURA YUKIHIKO
IPC: G07F7/08
Filed: 1987-09-18
Abstract: PURPOSE: To prevent a password from being watched surreptitiously and to prevent a card crime, and improve the secrecy of the card password code by fitting an easy-to-detach cover to a password code input device. CONSTITUTION: The cover 15 made of opaque resin which can not be seen through from outside is arranged on a password input unit 1. For example, when this device is used at the counter of a store, etc., the password that a card bearer himself or herself inputs is hardly watched surreptitiously by neither a clerk of the store or a 3rd person. Consequently, the positions of input keys 12a and 12b operated by the password input person can not be read by circumferential people and the password is prevented from being seen without changing the password at each time or using a password that is too complicated for the input person to remember.

Title: Electromagnetic rotating machine
Inventor: IMAI YASUAKI
IPC: H02K29/12
Filed: 1991-09-17
Abstract: PURPOSE:To obtain a small-sized electromagnetic rotating machine, cost of which is reduced, by making the AM component of the change of magnetic field intensity generated by one of two electromagnetic coupling elements installed to the rotor side and the stator side, affecting to the other, to 1ppr. CONSTITUTION:A change by the revolution of a rotor 4 in a magnetic field generated by an FG magnet 2 is detected by a generating wire element 7a. The output signal of the generating wire element 7a generates sixty pulses per one revolution (60ppr) because one hundred and twenty magnetizing inversion is executed to the magnet 2. The sixty pulses are modulated by a sine wave of 1ppr. The AM modulation signal is half-wave rectified, and sample-and-hold processed, thus acquiring a rotational-position detecting signal. That is, magnetic field intensity between two electromagnetic coupling elements is AM-modulated by 1ppr, and a rotational position signal can be formed from the modulation component, thus omitting a rotary magnet exclusive for a conventional index and an element for detecting a rotational position.

Filed: 1989-09-14
Abstract: PURPOSE:To reduce time for write recovery by providing a clamping circuit in a common sense line, which commonly connects the collectors of plural transistors, in a high-speed sense circuit to be frequently used in a bipolar memory. CONSTITUTION:When write is finished and a write control signal VRO is changed from a low potential to a high potential, the potential of a common sense line CS 0 is increased by coupling through capacitors between the bases and the collectors of transistors QS10-QSn0. However, when the potential of the line CS 0 is slightly increased, a diode DLC 0 in a clamp circuit CL is turned to a conducting state and operated so as to prevent the potential of the common sense line from being increased any more. Thus, the time for write recovery can be reduced and cycle time can be accelerated.

Filed: 1988-09-20
Abstract: PURPOSE:To directly obtain an arbitrary A/D conversion value corresponding to an analog value by providing an address decoder and a memory, and setting a conversion value corresponding to the analog value on the memory in advance. CONSTITUTION:The conversion value corresponding to an analog input value is set on the memory 7A before A/D conversion is performed.

As a result, the digital output 8A can be obtained directly against analog input as the value of desired code format, which eliminate necessity to perform the conversion of an A/D-converted value again. Therefore, it is possible to efficiently perform the A/D conversion.
