Title: Optical pickup device
Inventor: NAKAYAMA MASAHIKO
IPC: G11B7/09
Filed: 1989-01-20
Abstract: PURPOSE:To accurately detect the tilt of an optical information recording medium by detecting the displacement of the condensing position of a 0-th order reflected light by means of an objective lens with a divided light receiving element. CONSTITUTION:When a parallel light flux from a light source side is made incident on an objective lens 50, a part of the light flux is made incident on an optical information recording medium 6 as 0-th order light (j), and when it is reflected as the parallel light flux, it is made incident on the objective lens 50 as the 0-th order reflected light. Further one part of it is diffracted to be a condensed light flux 1, and condensed to the light source side focal position of the objective lens 50. When the optical information recording medium 6 has the tilt, the condensing position of the condensed light flux 1 is shifted in the direction orthogonal to the optical axis of the objective lens 50 away from the focal position. That is, at a divided light receiving element 90, the position of a spot S shifts in the direction of either one light receiving part, a tilt detecting signal is obtained from the output of the light receiving part, and the corresponding relation between the tilt detecting signal and a tilt angle theta is obtained. Thus the tilt of the optical information recording medium 6 can be accurately detected.

IPC: F03G6/00
Filed: 1982-01-27
Abstract: PURPOSE:To prevent extreme reduction of efficiency and occurrence of abnormal sounds by completing the heating of working liquid in the gas phase area without completing the heating in the gas-liquid mixing area even if a sun-beam amount to a heat collector-generator is reduced. CONSTITUTION:A standard pattern in the case of large sunbeam amount to a heat collector-generator 1 is represented by 10-11-12-13-10 in Moriel diagram of Rankine cycle 5. Overheating dgree in gas phase of heating process 11-12 in this case is represented by 14-12. When the sun beam amount is lowered, a control circuit 9 generates a control signal for reducing the rotational frequency of a working fluid pump 4 thereto so that detected temperature difference between temperature sensors A7, B8 have the same value as 14-12 and a circulating amount of the working fluid to the heat collector-generator 1 is reduced. Thus, since the cycle pattern of the working fluid is represented by 10-11b-12b-13b- 10, the degree of overheat is represented by 14b-12b so that the working fluid will be expanded from the complete gas phase area rather than gas-liquid mixing area.

Title: Semiconductor integrated circuit
Inventor: MATSUMOTO SATOSHI
IPC: G11C7/00
Filed: 1988-01-22
Abstract: PURPOSE:To hold temporarily data in case the data stays at an output part and to transfer the data at a high speed via a bypass line when no data stays at the output part by providing the bypass line to a data transmission line having a return structure obtained by connecting the data memory means in many steps to bypass between the data memory means set on the going and coming-back routes. CONSTITUTION:When the data DATA and a transmission signal C10 are inputted to a data transmission means 10, the data presence/absence detecting parts 70 and 80 detect that the significant data are included in the data transmission means 50 and 60 and inhibit a bypass line by the signals CTL1 and CTL2. Thus the DATA and the signal C10 are transmitted to a data transmission means 40 via the data transmission means 20 and 30. In this case, however, the transmission of data is stopped at the means 40 since the transmission permitting signal shows an inhibition state. While the data are transmitted via the bypass line in case no significant data is included in the means 50 and 60.
