Title: Image/voice transmission device
Inventor: IMAIDA SATORU
IPC: H04M3/00
Filed: 1989-06-01
Abstract: PURPOSE:To protect one's face and figure and the state in a home, and to eliminate the anxiety of a user by sending his own image after confirming the other party. CONSTITUTION:A call setting message is sent out against a switching network 100 from the other station 104 to one's own station 30.

Abstract: PURPOSE:To prevent damages to a refrigerant transfer device by a method wherein the refrigerant pressures in heat source side and service side refrigerant cycles are detected to detect refrigerant leakage in the service side refrigerant cycle according to the pressure difference between those refrigerant cycles. CONSTITUTION:During cooling operation, the capacity of a heat source refrigerant cycle and the capacity of a refrigerant transfer device 21 are controlled so that the heat source side and service side refrigerant cycles are operated at a constant pressure difference between those refrigerant cycles depending upon the load of room units (g) and (h).

However, the refrigerant pressure difference between the heat source side and service side refrigerant cycles gradually increases. The refrigerant pressures in two refrigerant cycles are detected by pressure detectors 31a and 31b respectively, and when the pressure difference exceeds a specified value, that is, before a large amount of gas refrigerant flows into the refrigerant transfer device 21 and the refrigerant transfer capacity drops extremely resulting in a considerable reduction in cooling or heating capacity and in damages to bearings of the refrigerant transfer device 21 due to lack of lubrication, an abnormal signal is indicated and the operation of a cooling and heating apparatus is shut down.

Title: Magnetic head
Inventor: KOSHIMOTO YASUHIRO
IPC: G11B5/02
Filed: 1979-11-05
Abstract: PURPOSE:To decrease the number of terminals of a position detecting head that detecting head that detects the position on a magnetic disk by making use of a decrease in reproduced signal output due to the position shift in magnetic head, by eliminating the need for a level detector by making use of the magnetic resistance effect. CONSTITUTION:Electric currents are flowed individually from constant current sources 11a and 11b to two MR elements (magnetic resistance effect element) 10a and 10b and common return line 12 is used. Consequently, the current application line can be utilized as a differential signal detection line, so that only three lines will be sufficient. Even when many position detecting heads 8a and 8b are used to improve the SN ratio, the resistance values can be added because MR elements 10a and 10b themselves have the property of rectification, so that position detecting heads 8a and 8b will only be connected in series in one direction. Thus, the number of terminals is not increased at all.

Title: Method and circuit for chain search
Inventor: HANAKI YOSHITAKA
IPC: H03M13/00
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To perform efficient and high speed processing by providing a completion control step and the like which compares storage contents of an order storage step of an error position polynomial f(x) with calculation contents of a solution number calculation step and completes chain search operation per encoding length when the number of solutions becomes equal to the order of the f(x). SOLUTION: In order to count the number of (x) satisfying f(x)=0, 1 is added to a variable (j) and incremented every time such an (x) is obtained (S107). Next, it is decided whether or not a value of the variable (j) for counting the number of (x) satisfying the f(x)=0 is equal to an order (k) of a polynomial f(x) which becomes an input (S108) and, when it is equal, it is judged that chain search operation is finished and the chain search operation is completed. In this way, since, in this chain search method, every time a solution of the f(x) is obtained, the number of the solutions is compared with the order of the equation. If both are equal to each other, a calculation is not performed for obtaining the following solutions, so it is possible to perform processing at high speed.
