Title: High pressure fuel injection device for engine
Inventor: TAGAMI ATSUSHI
IPC: F02M59/20
Filed: 1988-03-25
Abstract: PURPOSE:To specify a fuel injection amount per combustion at a time in a wide speed area, by a method wherein an output phase varying means is controlled so that a delivery pressure at the fuel injection timing of a fuel injection pump is low in an engine low rotation speed area and is increased with the increase in a rotation speed. CONSTITUTION:Through circumferential movement of a roller 57 toward a disc cam 53 through running of a motor, the forward and backward movement timing of a plunger 51 is changed, and control is made so that a delivery pressure at a fuel injection timing is low in an engine low rotation speed area and increased with the increase in an engine rotation speed. As a result, in an engine high speed rotation area, by injection of fuel at a high fuel injection pressure, a given amount can be injected even for a short time. Besides, in an engine low speed area, by injecting fuel at a low fuel injection pressure, fuel can be injected in a manner that a fuel injection amount does not exceed a given amount even for a long time. This constitution enables a fuel injection amount per combustion at a time to be kept at a specified value in a wide speed area.

Title: Control-rod drive mechanism
Inventor: AISAKA TATSUYOSHI
IPC: G21C7/12
Filed: 1978-06-12
Abstract: PURPOSE: To decrease the quantity of the radiation of a reactor power plant, by using a sintered alloy of a chrome carbide, which employs a nickel or nickel base alloy as a combination phase, for a check valve of a control-rod drove mechanism.  
     CONSTITUTION: 10W70% nickel or nickel base alloy is mixed with chrome carbide as a combination phase, and sintered, thus forming an alloy. A check valve 1 is made of the alloy, and installed to a control-rod drive mechanism. The check valve 1 friction slides to a main body 4 when high-pressure water is change-over operated, but the quantity of the radiation of a reactor power plant can be decreased because cobalt is not contained in products due to frictional wear.

IPC: A61F2/28
Filed: 1995-03-28
Abstract: PURPOSE: To enables improvement in fitting to organic tissues and cells by providing a cover layer with the surface thereof having an OH group on the surface of a core body. CONSTITUTION: For example, in an artificial root, the surface of a core body 1 is purified rough by a blasting treatment to form a cover layer 2 comprising titanium on the core body 1 by a plasma blasting method. Then, the surface 3 of the cover layer 2 undergoes a hydrophilic treatment to introduce an OH group into the surface of the cover layer 2. This enables improvement in fitting to organic tissues and cells without lowering of adhesion strength between the cover layer 2 made of titanium or titanium oxide and the core body 1 and changing of affinity to the organic issues. A cobalt-chromium based alloy can be used as a material of the core body 1 and the hydrophilic treatment is performed by an eximer laser irradiation after dripping or applying of hydrogen peroxide.

Title: Video signal reproducer
Inventor: TAKAYAMA NOBUTOSHI
IPC: G11B15/467
Filed: 1983-04-20
Abstract: PURPOSE:To ensure the satisfactory tracking control even though a reproduced pilot signal has a level difference corresponding to the frequency difference, by switching the tracking control signal obtained in response to a pilot signal synchronously with the switch of a track where the reproduced video signal is obtained. CONSTITUTION:The frequency component f0 supplied to a terminal 32 from a wave detecting circuit forms normally a level variance. At the same time, the frequency component supplied from the wave detecting circuit from a terminal 33 also forms a level variance. If these frequency components are supplied as they are to a differential amplifier 36, the output (f) forms a large variance for each field. In this example, the positive reference voltage is applied to the positive input of the amplifier 36 from an electric power supply 39 in periods I and II. While the negative voltage is applied to the positive input of the amplifier 36 from an electric power supply 40 in periods III and IV. As a result, the positive input of the amplifier 36 is changed to a solid line from a broken line of Fig. (e). Thus the output of the amplifier 36 is changed to a solid line from a broken line of Fig. (f). This can reduce the error signal due to the characteristics of a head to the frequency of a pilot signal.
