Filed: 1990-05-09
Abstract: PURPOSE:To obtain a product wherein enough fusion has reached the inner part even if the thickness of a molded item is thick or the foaming ratio thereof is high by performing evacuation of gas existing in gaps between foamable particles filled in a cavity with steam under a pressurized condition. CONSTITUTION:In a cavity 21 of a mold consisting of a fixed mold 11 with a steam hole 20 and a movable mold 12 with a steam hole 20', wherein the pressure is elevated with a pressurized gas, thermoplastic resin foamable particles are filled while being compressed by using this pressurized gas. After the pressure of the cavity 21 after pressurized filling is furthermore elevated than the pressure at filling time, a steam for evacuation with a pressure which is 0.2kg/cm or more higher than the inner pressure of the cavity 21 is passed through from the steam holes 20 and 21'. Then, the pressure in the cavity 21 is returned to the atmospheric pressure and the compressed foamable particles are returned and expanded to their original condition in the cavity and are furthermore heat-fused together.

Title: Solid-state image sensing device and manufacture thereof
Inventor: KITAMURA YUJI
IPC: H04N5/3725
Filed: 1988-05-16
Abstract: PURPOSE:To prevent the generation of the punch-through action of MOSFETs and to prevent the deterioration of the gain characteristics of an output circuit by a method wherein the impurity concentration of a diffused region for power supply side MOSFETs of the output circuit is formed lower than that of a diffused region for grounding side MOSFETs of the output circuit. CONSTITUTION:The impurity concentration of a diffused region 50', where the power supply side T11 and T21 among MOSFETs-T11, T12, T21 and T22- constituting an output circuit of an output part 4' and formed, is formed lower than that of a high-concentration diffused region 51 where the earth side T12 and T22 are formed. Moreover, source voltages of the T11 and T21 are equal to a voltage drop due to the resistances between sources and drains of the T12 and T22, source voltages of the T12 and T22 are an earth voltage, the regions 50' and 51 are earthed and a substrate voltage is applied to an Si substrate. Accordingly, the punch-through action of the MOSFETs is hardly generated by the potentials of the T11 and T21 and the punch-through action becomes easy to generate by the potentials of the T12 and T22. Thereby, by forming the impurity concentration of the region 51 in a high concentration, the generation of the punch-through action can be prevented sufficiently.

Title: Fuel supply system for internal combustion engine
Inventor: MINAGAWA KAZUJI
IPC: F02M55/00
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To effectively suppress a fuel pressure fluctuation in time of a sudden change in fuel injection quantity. SOLUTION: A damper means 20 is installed in the tip part of a delivery pipe 16 to distribute fuel to each fuel injection valve of respective cylinders. This damper means 20 suppresses any fuel pressure fluctuation by way of varying the content volume of a fuel piping system according to this fuel pressure fluctuation (fluctuation in a fuel fill in the fuel piping system) after a bellows 23 is expanded or contracted in the axial directions (both directions of arrows A and B) according to this fuel pressure fluctuation in the fuel piping system. When the quality of material and the elasticity of a spring 27 are properly selected, a characteristic of expansion dispalcement in the bellows 23 is set up so as to make a fuel pressure fluctuation rate to the fluctuation of the fuel fill in the fuel piping system be settled withing the range of 10 to 50kPa/cc.  With this constitution, fuel fluctuation suppressing effect and fuel pressure convergence in time of a sudden change in fuel injection quantity are reconciled, thereby improving a fuel pressure control characteristic in time of the sudden change of fuel injection quantity, and thus emission and drivability are improved.

Title: Own weight compensating method for master manipulator for remote control
Inventor: MAEKAWA AKIHIRO
IPC: B25J3/04
Filed: 1988-05-16
Abstract: PURPOSE:To reduce sense of fatigue at the time of operation by applying a torque to a master manipulator directed upward at all times when the attitude of one's own arm is to be held constant, and allowing the arm of the operator to be placed upon a master arm. CONSTITUTION:The output from an angle sensing means 3 is entered into a computer 10, and at an own weight torque calculating means 4, the target value for the torque due to own weight of each shaft of a master arm 1 is determined on the assumption that the value of compensative acceleration alphais greater than the acceleration g of the gravity. As a result an upward directed force is generated to the master arm 1, and when the operator wishes to keep his arm in constant attitude during operation of the master arm 1, he can put his own arm on the master arm 1 to lead to reduction of fatigue at the time of operation.

Hereby, the controller 6 takes in the signal 8 and the signal 9 as the data, and determines the optimum pattern of the dissolved oxygen concentration in each room AWD. The controller 6 compares this optimum pattern with the actually detected value of each room, and adjusts the air supply control valves 4aW4d for each room so as to make the distribution condition of the dissolved O 2  concentration of each room to coincide with the optimum pattern, and generates the control signals 7aW7d. As a result, the distribution pattern of dissolved O 2  concentration in the aeration tank 1 can be controlled to the optimum condition at excellent accuracy.
