Patent JP-H088941-A (JP)
Title: Single direction loop transmission circuit
Inventor: KAWADA SHINYA
IPC: H04L12/42
Filed: 1994-06-23
Abstract: PURPOSE:To allow a circuit to conduct reception and rewrite transfer of communication data in real time. CONSTITUTION:An idle signal (a) outputted from a FIFO memory 6 is inverted by an inverter 10 in a station 1 receiving communication data to obtain a reception interrupt signal (e), which is given to a processor 11 to start reception interruption. Furthermore, a weight control signal (c) generates the idle signal (a) to input it to the processor 11 thereby adjusting a reception data access timing. On the other hand, when a head part of communication data is read by the processor 11 in the reception interrupt program, the scheduling of data processing is decided based on the length of data written in control head data of the head part to start processing of the communication data. When communication data in a FIFO memory 6 are addressed to both own and other stations, the communication data are received in the processor 11 and outputted to a transmission line 4 while being rewritten in parallel.

Title: Cable connecting structure
Inventor: KANEKO TAKASHI
IPC: G02B6/36
Filed: 1990-06-22
Abstract: PURPOSE:To connect cables well by improving seal effect at a cable insertion part of an end plate, and making the end plate to correspond to cables having different outer diameter from each other without changing size of the end plate. CONSTITUTION:Since a bushing 22 made of the elastic material such as rubber is engaged with a through hole 20 formed in an end plate 12, in the case that the end plate 12 receives heat cycle to repeat the expansion and the shrinkage, this expansion and shringkage is absorbed by the elastic force of the bushing 22. Since flange parts 26, 28 are formed in both sides of the bushing 22, seal effect is generated. Furthermore, for cables 6 having different outer diameter, several kinds of bushing 22 with a cable insertion hole 24 having different diameter are prepaired previously, and since a diameter of the through hole 20 of the end plate 12 is manufactured in response to an outer diameter of the bushing 22, the end plate 12 in one kind form can correspond to any cable.

Abstract: PURPOSE:To reduce leak magnetic flux at a front part and facilitate manufacture by setting the width of a main core to 0.3mm.<=W<=1.0mm. and the width of a reinforcing core equal to or larger than (w). CONSTITUTION:The width of the main core (w) of the magnetic head is set to 0.3mm.<=W<=1.0mm. and the width of the reinforcing core 11 is set equal to or larger than it.

Filed: 1985-07-26
Abstract: PURPOSE:To attain effective utilization of memory capacity and to decrease transmission time by extracting a picture signal from an image sensor as a picture read output when a picture reader moves on an original. CONSTITUTION:With a picture read switch 10 turned on in a control circuit 42, a signal representing that the picture reader 1 is placed on the original A is inputted to the circuit 42 and a pulse signal comes from a rotary encoder 18, then a picture signal from an image sensor 12 is transferred to a picture memory 43.

Title: Ignition timing control device for internal combustion engine
Inventor: TACHIBANA MINORU
IPC: F02P5/152
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To accurately reflect a learning value in knocking control relating to a region performing no learning, in an ignition timing control device for an internal combustion engine provided with a knocking control system having a learning function. SOLUTION: A learning value of knocking control in a region of PM2<PM (load) is AKGB for a new article and AKGM for a used article. A learning reflected value to be reflected to non-learning region of PM<PM2 based on the learning value is almost conformed to the value reduced in the AKGB toward a load PM1 with a knocking limit orthogonal to a basic ignition advance timing for a new article. For a used article, EAKG obtained by decreasing the AKGM with the same slope as a decreasing slope of the AKGB is adopted as the learning reflected value.
