Title: Photomagnetic recording medium
Inventor: OKADA MITSUYA
IPC: G11B11/10
Filed: 1985-02-19
Abstract: PURPOSE:To eliminate unerased areas when record information is rewritten by having the larger laser power in a 0-record mode than that in a 1-record mode. CONSTITUTION:Laser light given from a photomagnetic head 1 is irradiated on a photomagnetic disk 2. Both the semiconductor laser and the clock signal for drive of external magnetic field are produced by a clock signal generating circuit 3. These clock signals are supplied to a current source 4 for generation of external magnetic field and to a laser pulse current source 5. The external magnetic field generating current is modulated by the clock signal and the record binary signal and supplied to an air core coil 6. The laser pulse current is modulated by the clock signal and the record binary signal. Then the waveheight valve corresponding to '0' of the binary signal is set larger than that corresponding to '1' of the binary signal. Thus the temperature rising area of a disk track is increased and the magnetized reverse bits can be erased without leaving just a part of said reverse bit. This attains the 0-recording.

Title: Regenerator of absorption refrigerating machine
Inventor: FURUKAWA MASAHIRO
IPC: F25B30/06
Filed: 1993-01-28
Abstract: PURPOSE:To utilize even low temperature waste heat produced from factory plants and the like as a heat source by improving heat efficiency of a regenerator. CONSTITUTION:In a regenerator 1 of an absorption refrigerating machine, a sponge, like metal plate 14 is disposed above a group of horizontal heat transfer pipes 13A and in close vicinity of the same, so that an absorption fluid heated on the surface of the heat transfer pipe 13 has poor fluidity, and an absorption fluid in contact with the surface of the heat transfer pipe is easily overheated also directly by hot waste water discharged from a factory plant into the heat transfer pipe 13. Accordingly, boiling occurs not only on the heat transfer pipe but also on a contact fluid surface of the sponge like metal plate 14 which provides additional nucleus boiling. Hereby, boiling is promoted. Further, vapor bubbles formed with the boiling are held between the heat transfer pipe 13 and the sponge like metal plate 14, so that vaporization from the surrounding overheated fluid layers is induced to form an environment where vaporization is likely to occur, and hereby sharply improve heat transfer performance.

And the follower part 7a of the projecting lens 7 press-contacts with the follower part 6a of the deflecting mirror 6 so as to interlock with each other in the rocking direction and the projecting lens 7 is rocked to alter the tilt angle of the lens 7. Since the rocking position of the projecting lens 7 can be corrected according to the variation of the tilt angle of the deflecting mirror 6 with a cam part formed on at least one of the follower parts 6a and 7a, the tilt of an image surface projected with an optical elevation angle with respect to a vertical screen can be corrected. Thus, the focusing of the image surface can be possible on all the surface of the screen.

Title: Optical head device
Inventor: NISHIWAKI SEIJI
IPC: G11B7/135
Filed: 1988-02-12
Abstract: PURPOSE:To minimize the off tracking of return light and to miniaturize the title device by providing a converging means to converge a converged laser beam on an optical disk recording face and detecting means to respectively detect quartered light flux. CONSTITUTION:The light reflected by an optical disk recording face 6 passes through a diaphragm lens 5 and 1/4 wavelength plate 4 again, reaches a polarizing beam splitter 3 and goes straight on through this. This return light 10 to go straight is narrowed down by a convex lens 7, passes through two parallel plates 8A and 8B and thus, it is level-divided into four. In this case, a difference occurs in the light quantity of the return light on light receiving elements 9C and 9D to the light quantity of the return light on light receiving elements 9A and 9B and a TE signal is generated. Consequently, by obtaining the difference signal of the outputs of adding amplifiers 11A and 11B by a differential amplifier 12A, a tracking error signal can be obtained. Thus, the return light is not deflected, a focus error signal and the tracking error signal can be detected by one photodetector and the title device is miniaturized.

Abstract: PURPOSE: To more accurately and smoothly transfer a data control from an ASR/SRR to an ASDE. CONSTITUTION: If a target tracked by a tracking processor 1 is decided to reach out of the coverage of an ASR/SRR by a coverage deciding unit 2, a landing runway is estimated by utilizing weather information and a flight plan in addition to the position and the advancing direction.

Not only the runway but also the landing speed and the landing position may be estimated. The altitude change which indicates an advancing angle, the estimating error obtained by a correlation processor 6 and the output of a PAR may be utilized instead of the weather information and the flight plan.
