Title: Magneto-optical disk device
Inventor: KANETANI YUKIYASU
IPC: G11B11/10
Filed: 1992-02-26
Abstract: PURPOSE:To prevent the destruction of recording data except an erasure part by reducing the intensity of a light beam to less intensity than a usual recorded information reproducing time when the beam irradiates a part except an erasure purpose part. CONSTITUTION:When an erasure control circuit 4 receives a stand-by signal, becomes a holding state erasable and an erasure power generation signal is sent to an erasure power current supply source 7 at the time of arriving at an erasure purpose position. The erasure power current supply source 7 receiving the signal supplies a laser driving current to a laser diode LD1 and increases the intensity of the beam to the intensity necessary for erasure and erases recorded information by irradiating the beam of the erasure power intensity to the erasure purpose part on a recording medium.

Title: Engine with turbocharger
Inventor: TADOKORO ASAO
IPC: F02B37/16
Filed: 1983-04-26
Abstract: PURPOSE:To improve the response of a turbocharger at the beginning of supercharging, by releasing the pressure of a supercharging passage down stream to the turbocharger at the time of non-supercharging to prevent the load upon the turbocharger from rising due to the increase in the pressure upstream to the turbocharger. CONSTITUTION:In the unsupercharged low-load operation of an engine E including its idling, a shutoff valve 17 is closed and another shutoff valve 19 is opened so that air pressurized by a turbocharger 14 is fed to an ordinary intake passage 11 through a communication passage 18. As a result, the pressure of a supercharging passage 13 downstream to the turbocharger 14 is kept from rising. The load upon the turbocharger 14 is thus prevented from increasing, to keep its rotational frequency high. For this reason, the response of the turbocharger 14 at the time of shifting to the supercharging of the engine E is imporved.

Title: Range finder
Inventor: NISHIRA HIROTAKA
IPC: G01C3/06
Filed: 1982-04-30
Abstract: PURPOSE:To provide a range finder incorporating, in place of conventional logarithmic amplifier circuit, a linear amplifier circuit having superior signal to noise ratio and resolution, by making use of a light-receiving element the input/ output characteristics of which vary depending on the position of incidence of light. CONSTITUTION:An SPD10 has a deformed light-receiving pattern 11 so that the rate of change of light-receiving sensitivity thereof varies in accordance with the shape of the pattern 11. The reflected light image 8 of a closer object 3 is within a part of low light-receiving sensitivity of the SPD10, while the reflected light image 7 of a remoter object 4 is in the part of high light-receiving sensitivity of the SPD10. The quantity of the reflected light is in inverse proportion to the distance to the object, so that it becomes possible to reduce the amount of change of the output current from SPD10 by forming the light-receiving pattern 11 in a shape corresponding to the expected amount of change of the reflected light quantity. It is, therefore, possible to use a linear amplifier circuit which is superior to the logarithmic amplifier circuit in the aspects of the signal to noise ratio and resolution, even with a power source of a comparatively low voltage.

Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To make friction-decreasing liquid spread all over a skin plate without requiring a complicated piping in sedimenting steel segment pieces by a method wherein ribbed steels or banded steels are used as skin plates. SOLUTION: A steel segment piece 21 is constructed by stretching a skin plate 29 all over the outside of a frame body formed of a main girder 23, a middle main girder, joint plates and vertical ribs. A ribbed steel with corrugations 31 formed at its external surface or a banded steel is used as the skin plate 29. Split rings each constructed by connecting the steel segment pieces 21 together in the circumferential direction are laid in tiers and connected with one another in the axial direction, and thereby a cylindrical sediment body is constructed and sedimented under the ground.  On sedimentation, water, bentonite suspension or the like supplied as friction-decreasing liquid from the surface of the ground is spread all over the external surface of the skin plate, running through openings formed by the corrugations 31 between the external surface of the skin plate 29 and the ground. Accordingly, the friction- decreasing liquid can be spread all over the external surface of the skin plate 29 without requiring a complicated piping.

Abstract: PURPOSE:To rapidly detect rain water, etc., even if the rain water, etc., intrude into a drum can by forming a waterproof film and rare earth element layer having water solubility on the inside surface of the drum can and fixing a cage housing waste via a cushion material to the inner side thereof. CONSTITUTION:After the waterproof film 4 and the rare earth element layer 5 are formed on the inside surface of the drum can 3, the container-shaped cushion material 2 is inserted into the drum can 3. Solid cement 1 is immobilized into the drum can 3 and thereafter, the cushion material 2a similar in material quality to the cushion material 2 is placed on the solid cement 1 and the drum can 3 is hermetically closed by mounting click stops 9 to the ends thereof or by other means. The drum can 3 immobilized with the solid cement 1 in such a manner is embedded into soil. Then, even if rain water intrudes into the drum can 3 by the impaired hermeticity thereof upon lapse of a long period of time, the rare earth element layer 5 on the inside surface of the drum is partly dissolved into the water by the rain water and the rare earth elements are thereby introduced together with the rain to a detector 12. The infiltration of the water into the drum can is thus detected.

Abstract: PURPOSE:To rapidly and surely make a body to be driven return to an initial position by giving the body to be driven a driving force to a 2nd direction by a driving force generating means for an instant only at an initial operation time in the case of displacing the body to be driven to the 2nd direction after displacing it to a 1st direction. CONSTITUTION:Stop boards 5 and being the bodies to be driven are displaced in an operating state and are kept in the state by energizing a meter 1 to one direction, and then, by stopping energizing the meter 1, the operation is switched to a recovery operation by the elastic force of an elastic body 9 for releasing the energy from being accumulated. At this time, a current in a direction reverse to an instant holding current is made to flow in the meter 1 so as to fix the direction for the recovery operation, so that the recovery operation can be smoothly and also rapidly performed. That means, in a driving device such as a stop device, etc., the driving force in the recovery operation direction is given for an instant when the mechanism falls into the most unstable state as to the mechanism in the case that a static state in the operating state is switched to an active state for performing the recovery operation. Thus, the recovery operation can be instantly started by the mechanism and can be stably performed.
