Patent JP-H02297507-A (JP)
Title: Optical connector
Inventor: OGAWA YUTAKA
IPC: G02B6/38
Filed: 1989-05-12
Abstract: PURPOSE:To improve the work efficiency by constituting this connector so that frictional force of one half part of a positioning pin and a pin hole of one connector block into which it is inserted becomes larger than frictional force of the other half part of the positioning pin and a pin hole of the other connector block into which it is inserted. CONSTITUTION:Two connector blocks 1A, 1B have the same shape and the same size, and the inside diameters of pin holes 5a, 5b are all the same. Also, a pair of positioning pins 2a, 2b also have the same shape and the same size, but both the positioning pins 2a, 2b are formed so that the outside diameter of one half part in the lengthwise direction becomes larger than that of the other half part. Accordingly, one of the positioning pins 2a, 2b, whose diameter is larger may be larger in frictional force with the pin hole, therefore, at the time of releasing the coupling, the positioning pin is always left in the connector block into which the part of a larger diameter is inserted. In such a way, the work efficiency can be improved.

Title: Input/output buffer memory system
Inventor: MARUI YOUJI
IPC: G06F13/36
Filed: 1983-06-29
Abstract: PURPOSE:To shorten an occupancy time of a bus even in case a data is inputted and outputted to and from an input/output (I/O) of a low speed, by providing an I/O buffer memory and a bus selecting FF in an I/O control device. CONSTITUTION:When an instruction for using a buffer memory IOM as an accumulating area of a data inputted and outputted to and from an I/O is inputted to a CPU, a control part CTL sets a bus selecting FF basing on a command of the CPU. Subsequently, when a data is inputted from the I/O, it is accumulated in the IOM, and when it reaches a prescribed quantity, it is transferred at a high speed to the CPU, etc. through a bus BUS. Also, the data outputted to the I/O from the CPU is transferred at a high speed to an input/output control device IOC through the BUS, and accumulated in the memory IOM. A circuit CTL outputs successively the data accumulated in the memory IOM to the I/O. Accordingly, even in case the data is inputted and outputted to and from the I/O of a low speed, an occupancy time of the bus can be shortened.

Title: Communication equipment between car and roadside equipment
Inventor: BANDAI HIROYASU
IPC: G08G1/09
Filed: 1992-05-11
Abstract: PURPOSE:To eliminate the interference waves of communication by providing a radio equipment for transmitting/receiving radio waves between base stations on a road and an obstacle detector for detecting upper obstacles. CONSTITUTION:When an obstacle detector 6 detects the presence of the road up in a mobile station traveling direction, a radio equipment 5 does not transmit the radio waves until it is out of the communication zone of the base station on the road under reception. Then, the base station on the road under reception repeats the similar procedure every time the radio waves from the base station on the road are received. Thus, in multi-level crossing roads, moving cars traveling the lower road can be prevented from applying the interference waves to the communication between the base stations on the road up in the mobile station traveling direction and the mobile station.

Title: Flashing device for close-up photographing
Inventor: TSUJI KENJI
IPC: G03B15/05
Filed: 1987-05-13
Abstract: PURPOSE:To previously detect the shadow of an object by arranging plural illuminating lamps so as to have almost the same light distribution as that of each light emitting parts and selectively emitting an illuminating lamp having almost the same light distribution as that of a light emitting part emitted at the time of photographing.

Title: Lens position changer
Inventor: YOSHII SEIJI
IPC: G02B7/00
Filed: 1983-06-29
Abstract: PURPOSE:To make a moving mechanism simpler, exclusively used region less and optical constitution simpler by providing at least one of a lens and a lens support and a driving source to the same moving body and changing the position of at least one part. CONSTITUTION:When a driving shaft 23 is rotated toward A by a driving source 10, a gear 24 attached to a driving shaft 23 is also rotated in the same direction (A) as the rotating direction of the driving shaft. Since the gear 24 is meshed with a rack 25, the rotating motion of the gear 24 is converted to linear motion by the rack 24 and a moving support 3 having a lens 1 and a lens support 2 is moved on a guide shaft 5 toward (a) by the rotating motion of the gear 24 toward A. The rotation of the shaft 23 toward B forces the support 3 to move toward (b). The need for a lever mechanism, etc. is thus eliminated, the occupying region for a lens moving mechanism is decreased and the construction is simplified.

Title: Logic integrated circuit
Inventor: SHIMONO TAKESHI
IPC: G06F11/22
Filed: 1991-05-23
Abstract: PURPOSE:To execute precisely a delay test of a path passing through a combinational logic circuit between F/F by making it possible to invert only an output of specified F/F. CONSTITUTION:When an enable input ENB is changed from 0 to 1 in a delay test of a delay measuring path 30, 12-i changes from 0 to 1 and an output of 5-i is inverted. A clock signal is inputted to a clock CLK 17, being delayed by a measuring time (tc) from the enable input ENB. As the result, scan F/F 4-j takes in negation of an output value (b) after the change in the delay measuring path 30, when a delay time (td) of the delay measuring path 30 is shorter than the measuring time (tc). A value of the scan F/F 4-j is read out by a scan- out operation and tested. The delay time (td) can be measured by observing a change in the F/F 4-j with the measuring time (tc) varied.
