Abstract: PURPOSE:To achieve a control excellent in responsiveness from an initial stage by comparing first and second elements multiplied by a quantity of first calculation among mutual intervention compensating elements used for a compensating elements used for a compensating means with those obtained by removing dynamics factors as theoretical values and setting the ratio thereof to a large value. CONSTITUTION:Deviation DELTAT between the evaporation temperature TR of a cooling medium and the target temperature TRO thereof and deviation DELTAS between the degree of superheat SH and the target degree of superheat SHO are calculated. A first quantity X of pseudo-operation is calculated by PID calculation based on the deviation DELTAT and a second quantity Y of pseudo- operation is calculated based on the deviation DELTAS. The quantity thetaa of valve travel operation and the quantity Da of compressor capacity operation are calculated from equations, that is, Da = X.alpha + Y.b12(0), thetaa = X.beta + Y.b22(0). Herein, alpha,beta, b12 (0) and b22(0) are constants (compensating elements). The change of the quantity thetaa of valve travel operation is emphasized larger and controlled, compared with the case in which theoretical values b11(0), b21(0) are used.

Inventor: EBISAWA KATSUHIDE
IPC: G11B11/105
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To easily obtain and to display the amount of warp by irradiating laser beams along the scanning lines directed from an inner periphery to an outer periphery of a disk and obtaining warp angles based on the amount of displacement from a positive reflection position of the reflected laser beams at plural measurement points on the scanning lines employing a first periphery of the inner peripheries as a reference. SOLUTION: A laser beam spot irradiates spiral scanning lines 1 to n, which are virtually drawn on a disk, and an information extracting is initiated at the starting point of a scanning line 1 n=1, i=1. The information extracting is conducted for I times with an equal interval for every periphery. The interval between adjacent scanning lines corresponds to a movement pitch p, the position of the scanning line 1 is assumed to be a flat surface, the amount of warp is assumed to be 0 and is used as a reference surface. The amount of warp from the reference surface is obtained from the value of the amount of displacement Xni of the reflected laser beams extracted at an arbitrary i-th position on an arbitrary n-th scanning line. Thus, the amount of warp is easily obtained and displayed based on the numerical data of the warp angles of the disk.

Filed: 1993-05-19
Abstract: PURPOSE:To reduce use parts and a mounting area and to provide a highly reliable private branch MODEM with a built-in branching function by using a photo-MOS relay for a circuit for turning transmission data signals ON/OFF during transmission and during reception. CONSTITUTION:When the photo-MOS relay 6 of a signal generation circuit 8 is turned to 'H,' the output 7 of the relay 6 is turned ON and the transmission data signals are outputted through a transformer 3 to a private branch transmission line 4. Also, the output 7 is turned OFF, impedance viewing the transformer 3 from the transmission line 4 becomes large and transmission data are not sent out. In the case of branching lines, since the control of the relay 5 of only a channel for performing transmission is turned ON, communication can be performed without superimposing on the transmission data signals of the other channel. Thus, the MODEM corresponding to the branching lines strong against surge noise is obtained.
