Title: Optical recording mediun
Inventor: GOTOU YASUYUKI
IPC: B41M5/24
Filed: 1982-09-30
Abstract: PURPOSE:To prevent deterioration of a film in a high humidity atmosphere and a drop of a write characteristic by constituting an optical recording medium by adding Cr of a specified range quantity to Te. CONSTITUTION:An optical recording medium 12 is formed and constituted on the surface of a substrate 11, but according to this invention, the optical recording medium 12 is formed by adding Cr of a small quantity to Te. The optical recording medium 12 can be formed by vapor-depositing Cr simultaneously with vapor-deposition of Te in a vacuum vapor-depositing device. In this case, when an adding quantity of Cr is varied, as a result, it becomes clear that an effect of durability of the medium appears remarkably as shown by a curve C, but in case of exceeding 15%, it is confirmed that write sensitivity drops little by little and laser light energy required for write increases as shown by a curve D. That is to say, when an adding quantity of Cr is set to 5-15% weight percentage, a desired result is obtained.

Title: Speed detector for commutator-less motor
Inventor: AKITA TAKAFUMI
IPC: G01P3/489
Filed: 1980-12-08
Abstract: PURPOSE:To eliminate noise produced by a large commutation of exciting current in a  machine in which the period information of signal induced in the exciting coil of a  commutator-less motor is used as a speed signal, by processing the speed signal by a  position signal. CONSTITUTION:A commutator-less motor has exciting coils Ma to Mc which are successively energized by electric current supplied from transistors 8 to 10 adapted to be  successively turned on by signals d to f derived from a position signal generator 29. A  rotor constituted by a permanent magnet is rotated as a result of the energization of  the exciting coils Ma to Mc. In each exciting coil, induced are a first spike voltage  generated by mutual induction when the exciting current is commutated in another  phase and a second spike voltage generated when the current of its own phase is cut. These spike voltage are shaped by circuits 11 to 13 and flip-flops 14 to 16 are set by  the first spike voltage. The flip-flops are then reset by the position signal e from the  phase next to the first-mentioned phase which produces an output h. Therefore, no second spike voltage appears in the output i. Then, a speed pulse k is produced by  monostable multivibrators 17 to 19. The speed pulse is converted into voltage through  an f-v conversion by a circuit 22, and a speed control is effected by a circuit 23.

Title: Inclined vibration sensor, inclined vibration sensor and portable alarm device
Inventor: HANEDA MAKOTO
IPC: G01C9/12
Filed: 1997-06-14
Abstract: PROBLEM TO BE SOLVED: To enable detection of the states of vibration and inclination with a single mechanism by identifying the vibration state, based on a change in capacitance between a mobile electrode varying with external vibration and a fixed electrode. SOLUTION: A change in the capacitance between a mobile electrode 6 and a fixed electrode 2 is converted to a change in frequency by an oscillation conversion part, and a value of the change in the frequency is outputted as pulse value by an interval counter part with a proper cycle to judge the vibration state, by computing the pulse value per cycle with an arithmetic section. In this case, the oscillation frequency is high when the capacitance is small, and the oscillation frequency is low when the capacitance is large. In other words, upright state at rest makes no great change in frequency. In the case of the existence of vibration, there is a frequent repetition of vertical change, and if in the levelled state at rest, there may be no great change in frequency.  Thus, the vibration, static state and levelled state are judged by computation, based on single sensor information of an inclined vibration sensor 1.

Title: Longitudinal high temperature regenerator device for gas absorption cold/hot water machine
Inventor: KUROSAWA MOKICHI
IPC: F25B33/00
Filed: 1989-07-05
Abstract: PURPOSE:To make a title device compact by disposing a fluid tube communicating with a fluid wall to be heated in a cyrindrical structure with its exhaust part on its upper part so as to cross the cylindrical structure slantingly longitudinally, mounting a fin on the fluid tube and disposing a burner below the cylindrical structure. CONSTITUTION:Once combustion is started in a burner 6, combustion gas is raised in its temperature heating a fluid wall 2 to be heated and a fluid tube 4. The fluid tubes 4 are disposed to cross each other slantingly longitudinally, so heat exchanger is with a cross type to greatly improve heating efficiency. More specifically, since the fluid tubes 4 are disposed to cross each other slantingly longitudinally, a heat transfer area is increased and the rising combustion gas becomes turbulent owing to the fluid tubes to sharply improve the heating efficiency. When such fluid tubes are crossed slantingly at the upper portion, the combustion gas is not cooled rapidly in a space at the lower portion of the device and exchanges heat in a completely burned state. Additionally, since the fluid tubes 4 are constructed slantingly, bubbles in the tube are easily released to improve the heating efficiency and hence make the device more compact.
