Title: Method and apparatus for driving pile
Inventor: OGATA KOUJIROU
IPC: E02D7/18
Filed: 1979-12-13
Abstract: PURPOSE: To permit the driving of pile even into sand layer by a method in which liquid is supplied from the top of a pile while regulating the specific gravity and viscosity of the liquid according to the grain size of the soil at the tip of the pile so as to force the soil to the ground surface.  
     CONSTITUTION: A pile 1 is driven while applying an axially right angle-directional vibration to the pile 1 by means of a vibrator 2. In case where soil at the tip of the pile is clay, a liquid of a high specific gravity and a high viscosity, e.g., bentonite liquid, to be discharged from a tank 11 by a pump 13 is reduced its discharge amount. Also, in case where the soil at the tip of the pile is sand, a liquid of a low specific gravity and a low viscosity, e.g., water, to be discharged from a tank 12 by a pump 14 is reduced its discharge amount, and then the pile 1 is driven by increasing the specific gravity and viscosity of the liquid to be supplied. In short, the outflow of soil to the ground surface is made possible without the necessity for increasing the amount of the liquid to be supplied because, even if the grain size d of soil becomes large, the flow rat can be made smaller by correspondingly increasing at least one of the specific gravity and the viscosity of the liquid.

Title: Controller for power window regulator
Inventor: KOKUBU SADAO
IPC: B60J1/17
Filed: 1990-06-19
Abstract: PURPOSE:To stabilize the amount of time required for tightening a windowpane by providing a clamping circuit which clamps to a constant voltage higher than a reference voltage a detected voltage proportional to a voltage at each end of a condensor which functions as a timer. CONSTITUTION:When an automatic mode switch 4 is turned on a first comparing circuit 29 is turned into its off state and a condensor 25 is instantly charged with electricity and a detected voltage is instantly raised to the maximum voltage. Thereby the detected voltage becomes larger than a reference voltage and a second comparing circuit 40 is reversed into its off state. Even when the automatic mode switch 4 is turned off, a windowpane is automatically lifted. When the windowpane reaches to its uppermost position the first comparing circuit 29 is reversed into its on state and discharge of the charged potential of the condensor 25 is started but it takes a long time for the detected voltage to reach to below the reference voltage. Thereby tightening of the windowpane is made possible.

Title: Tape tension control mechanism
Inventor: TAKEDA HIDEKAZU
IPC: G11B15/43
Filed: 1994-07-13
Abstract: PURPOSE:To prevent damage and expansion of a tape which is thin by imparting an optimum sub-brake torque corresponding to detected revolving speed of a reel to the tape reel. CONSTITUTION:Reel revolving speed is detected by a reel revolving speed detecting sensor 20. Subsequently, optimum reel load torque corresponding to this reel revolving speed inputted previously in a memory 21 is selected in comparison by a comparison calculator 22, and a driving motor 18 is driven by a mechanical mode control circuit 23 having received a selecting condition. At this time, a rotated position of a sub-brake torque control cam 17 is detected by a mode detecting sensor 24, and the detected information and the information from the comparison calculator 22 are arithmetically processed by the circuit 23 to calculate a rotation stopping position of the cam 17, and optimum load torque by a sub-brake arm 13 is imparted to a supply reel base 10. Consequently, even when a tape winding diameter is changed, the tape tension can be kept approximately constant, and hence good recording and reproducing can be carried out.

Title: Coated part
Inventor: NISHIMURA YASUSHI
IPC: B05D5/00
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To provide a coated part less apt to be damaged at a low cost. SOLUTION: A reel main body 1 of a double bearing reel is a part whose surface is coated and which is provided with a base part 10 made of a metal, an oxidized coating film layer 11, a substrate coating film layer 12 and a finish coating film layer. The finish coating film layer 13 is a layer obtained by application of self-curing coating material. In the reel main body 1, since the coating film layer whose surface is coated with the self-curing coating material is formed, a damaged part is cured by itself and the coating film on the surface is regenerated even if damaged. Therefore even if the coating film on the surface is damaged, the damage is not left and consequently the coating film is less apt to be damaged. Moreover, since the coating film layer is a layer formed by application of a coating material, the layer is readily formed at a low cost.

Title: Differential pressure measuring device
Inventor: OOSHIMA TADASHI
IPC: G01L13/02
Filed: 1982-09-16
Abstract: PURPOSE:To obtain a differential pressure measuring device which scarcely causes an attitude error, and is excellent in vibration resistance and excessive pressure protection, by communicating the other measuring chamber with one pressure receiving chamber, and the other compensating chamber with the other pressure receiving chamber, respectively, so that a force exerting on the pressure receiving chamber and a force generated by the mass of a compensating pressure receiving element and a center plate are balanced. CONSTITUTION:In case when measuring pressure is led into pressure leading chambers 71, 81, respectively, the operation is the same as before because the spring rigidity of a compensating diaphragm 9 is small and soft, as compared with that of a measuring diaphragm 1. In case when gravity acceleration is exerting in the direction Y, other force than differential pressure does not exert on the measuring diaphragm 1. When the attitude is changed and the direction of acceleration (acceleration in the measuring direction) becomes the direction X, the influence is exerted on a measured value. In this case, the weight of a center plate 93 and the compensating diaphragm 9 is constituted to a value by which it becomes equal to the force put on the compensating diaphragm, and in accordance with the acceleration in the measuring direction, the force exerting on the measuring diaphragm 1 becomes zero. That is to say, it is possible to obtain that which scarcely causes an attitude error and is excellent in vibration resistance.
