Title: Magnetic recorder-reproducer
Inventor: TSUNODA MASAHIKO
IPC: G11B5/596
Filed: 1990-11-21
Abstract: PURPOSE:To position a head with high accuracy by installing LPFs having different characteristics and reducing the amplitude error of servo data without lowering the phase error of normal data. CONSTITUTION:Normal data passed through an LPF 25a are differentiated by a differentiating circuit 26, and compared with reference voltage by a comparator 27. A pulse signal corresponding to the peak position of a read signal is formed by a pulse generating circuit 28 by an output from the comparator 27. The pulse signal and a clock signal are synchronized with each other, and a phase synchronizing circuit 29 outputs read data. On the other hand, servo data are passed through an LPF 25b, and transmitted over a servo reproduction system composed of a sample-and-hold circuit 30. Gain characteristics are deteriorated steeply from cut-off frequency in the LPF 25b. Accordingly, the noise component of high frequency exceeding cut-off frequency can be removed by the LPF 25b without lowering a phase error.

Title: Space heating and cooling apparatus
Inventor: IMABAYASHI SATOSHI
IPC: F25B13/00
Filed: 1990-11-21
Abstract: PURPOSE:To prevent abnormal temperature rise of a compressor by a method wherein changes in the temperature detected by a temperature detector are compared with a comparison reference that is based on such a characteristic that the temperature of the compressor rises higher than a specified temperature during refrigerant recovery operation. CONSTITUTION:During refrigerant recovery operation, the temperature of a compressor 1 linearly rises with operation time. Therefore, when a specified time period ts required for refrigerant recovery operation is decided, the temperature rise DELTAT of the compressor 1 is decided, so that a specified temperature difference Ts is set at a value little smaller than the temperature rise DELTAT. Therefore, in the case the detected result of a temperature detector 34 of the compressor 1 is lower than the specified temperature difference Ts after the refrigerant recovery operation is carried out for a specified time period, it is assumed that the temperature detector 34 fails in detecting temperature because the temperature detector 34 is set up wrong or completely slid out of place or it loses its own characteristic. In either cases, it is an abnormal phenomenon and an apparatus is stopped.
