Title: Controller
Inventor: UCHIYAMA MASAJI
IPC: H04L29/02
Filed: 1990-03-02
Abstract: PURPOSE:To realize data warrant in communication without a controller with a small sized circuit by generating a read signal to a communication means with an address latch signal of a CPU and a read request signal from the communication means. CONSTITUTION:A transmission register 4 fetches a data from a CPU 1 and reads the data fetched by a transmission means 6 asynchronously with the operation. On the other hand, since the fetch operation of the transmission means 6 is implemented while the CPU 1 does not output a data (for a period when an address latch signal 7 is at a low level), the data read by the transmission means 6 is not indefinite. Thus, the data is communicated surely with addition of a small sized circuit to apply the control of a controlled system.

Title: Manufacture of chip resistor
Inventor: WADA HISANOBU
IPC: H01C17/00
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To reduce the cutting distance by laser trimming in resistance value correction, by making the width between electrodes to be printed and formed smaller toward the peripheral part than the central part in the direction vertical to the direction of a printing squeegee of an insulating board. SOLUTION: The film thickness of a resistor formed on an alumina substrate 101 by a printing squeegee can not be uniform, so that irregularity is generated in the resistance value. As to the resistance value distribution in the direction vertical to the direction of a printing squeezee, when the resistance value of the substrate central part is R, a resistance value increases toward the peripheral part, and the resistance value R' of the outermost part is R'=1.1R which gives the highest resistance value. In order to cope with the irregularity of the resistance value, an electrode 103 is formed in the following manner. The electrode width in the substrate central part is L. The electrode width l is so adjusted that the width l satisfies a relation of l=(R/R')×L and becomes l=0.9L in the outermost periphery.  A resistor is so formed that a part of the resistor overlaps with an electrode 103.

Title: Caster
IPC: B60B33/00
Filed: 1992-03-10
Abstract: PURPOSE:To ease switching of an advance direction of a caster by installing a magnet, which gives magnetic force to a periphery on a long diameter side of a cam, in a wheel receiving frame. CONSTITUTION:When a mobile body is to go backward, a wheel receiving frame 4 is rotated with the force overcoming the magnetic force of a magnet M1, so that a periphery 2a on a long diameter side of a cam 2 is not affected by the magnetic force of the magnet M1. Next, the wheel receiving frame 4 is further rotated until it comes to be rotated by an angle of 180 deg. from the initial state, so that the periphery 2a on the long diameter side and on the opposite side of the cam 2 is affected by the magnetic force of the magnet M1. In this state, the cam 2 tends to maintain a state, in which the periphery 2a on the long diameter side is near to the magnet M1, and moreover tends to go back to the state, in which the periphery 2a on the longest diameter side most approaches the magnet M1. Accordingly, the caster shows an excellent characteristic of going straight with this situation.

Abstract: PURPOSE:To attain the unitary control for the conference data by sending the data change information including the additional descriptions and corrections carried out by a device of the data receiver side to a device of the data sender side and performing the unitary control of data at the data sender side. CONSTITUTION:When an electronic conference is held with use of the conference data stored in a device A, the device A adds the address of its own and the intra-device data control numbers to the data during the conference. These data are held in the device A and at the same time distributed to the devices B and C as shown by the thick arrows 1, 2 and 3 via the communication channels. In such a way, the address of a data sender (device) A, the data numbers that can specify the data, etc., are added to the conference data to be distributed in order to uniquely specify the data to the conference data in a system. Thus the data receivers (devices) B and C transmit the data change information to the sender A if the sender A corrects the distributed data. The sender A performs the unitary control of the original texts based on the information.
