Title: Micrometer
Inventor: YAMANAKA KYOICHI
IPC: G01B3/18
Filed: 1992-04-27
Abstract: PURPOSE:To obtain a micrometer of superior measuring workability, without occurring an abutted flaw on the surface of an object to be measured. CONSTITUTION:In a micrometer, a probe 1 has a contact plane 11 perpendicular to a side wall 13 thereof, and an arcuate part 12 of a curved surface between the plane 11 and the wall 13. By this, even if the plane 11 is located and contacted, obliquely to the surface of an object to be measured, an abutted flaw does not occur, because the corner part of the probe 1 has the arcuate part 12. The dimension of the object can be easily and accurately measured because the area of the plane 11 is small, and therefore the micrometer has superior measuring workability.

Abstract: PURPOSE:To provide a simple and inexpensive communication equipment superior in flexibility of system design. CONSTITUTION:A transmission synthesizing circuit 2 sends transmission signals alphaand beta issued from CPUs 1A and 1B to a transmission line 4 as they are and outputs a discrimination signal gamma which has the signal level changed in accordance with transmission signals alpha and beta sent at this time. CPUs 1A and 1B issue transmission signals alpha and beta to permit the serial communication when the time preliminarily set in accordance with the signal level of the discrimination signal gamma elapses. Since the transmission synthesizing circuit 2 is realized with a simple constitution and is shared between plural CPUs 1A and 1B, the whole of the device constitution is considerably simplified and is made inexpensive. The preliminarily set time can be properly changed by software, and the number of degrees of freedom on the communication system design is secured.

IPC: G07G1/12
Filed: 1981-08-31
Abstract: PURPOSE:To make a new transaction during registration possible, by storing a credit amount of a vacant area of the credit memory and outputting a credit code, if no credit amount is present in the input of the credit code. CONSTITUTION:A credit code is generated through the depression of a credit code key. If no credit anount exists in a credit amount storage area, an entry buffer memory (NBM) and an entry flag (NF) are cleared. When the credit amount exists, the amount is transferred to the 1st operation memory (IM1) and a credit code in the entry buffer memory (MBM) is set to a credit code memory (CCM). After this credit code is printed, a loop discriminating the presence/absence of key input is repeated. Thus, new transactions can be performed  during registration and the credit code where the credit amount is cleared can  be used by other customers.

Title: Logic circuit
Inventor: MIIKEIREI YANGU
IPC: G06F11/26
Filed: 1987-05-29
Abstract: A programmable array logic device including a programmable logic array, at least one register pair, a multiplexer coupled to the register pair so that they can share a common I/O pin, and an observability buffer for controlling the multiplexer. A dual clock buffer is provided so that registers within the register pair can be clocked singly when in a preload mode or together when in a logic or verification mode. When in the logic mode, either the output of a buried state register or a output register is observed at the I/O pin under the control of a product term generated by the logic array. When in the preload mode the register to be preloaded is selected by an externally provided preload select signal. In the verification mode, which typically follows a programming mode, individually selected product terms within the logic array can be observed by clocking them into the register pairs.
