Title: Cooker with weight sensor
Inventor: NISHIMURA NOBUICHI
IPC: F24C7/02
Filed: 1985-12-27
Abstract: PURPOSE:To be able to make constantly exact weight detection and also satisfactorily finished cooking and carrying out zero point adjustment for the output of a weight sensor automatically when a foodstuff detecting means finds out no existence of foodstuff and the detected temp. of a temp. detecting means is under a given value. CONSTITUTION:When a user removes foodstuff from a shelf plate 2 after cooking is finished, detected weight becomes weight W of only the shelf plate 2 itself. After a while, temp. in a heating chamber 1 is decreased and detected temp. found out by a temp. sensor 9 and a temp. detecting circuit 10 is lowered under a given value (a term between Tb-Tc). A control part 20 detects that the foodstuff is removed from the plate 2 on the basis of the condition that detected weight becomes W (or 'W+DELTAW'). When temp. in the heating chamber becomes under a given value (point Tc), zero point adjustment for the output of a weight sensor 3 is automatically carried out. If the detected weight shifts to 'W+DELTAW' and the output V of the sensor 3 takes such a relation as V=a.W+b, V is returned back to an original relation V=a.W.

Title: Electrostatic countermeasure structure of operation panel
Inventor: NAKAJIMA YASUMASA
IPC: H05F1/00
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To prevent spark discharge toward inside resulting from charged static electricity by forming an opening provided in an operation panel so as to form a gap against a setting component such as a temperature adjusting knob or the like, and standing providing a cylinder wall on the peripheral edge of the opening in an electric cooking device or the like. SOLUTION: In an electric cooking device such as an oven or the like, when air becomes dry, static electricity is charged on the surface of an operation portion, spark charge is generated to an encoder 22E so as to adversely affect the control portion, and the runaway of a microcomputer may sometimes happen. A cylinder wall 2W surrounding the top side base portion of the encoder 22E is formed integrally with an operation panel which supports a board 2' and is simultaneously hidden by a resin sheet in such a height as not interfering plate pieces 22F. Thereby, creeping distance for sparking from the surface of the operation portion to the base portion of the encoder 22E via the cylinder wall 2W is lengthened so that spark discharge to the encoder 22E by the static electricity can be prevented by a simple structure.

Title: Axial piston type hydraulic pump
Inventor: TAKESHITA SEIICHIRO
IPC: F04B1/22
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To restrain pulsation, and effectively prevent vibration and a noise by setting a length of a notch groove extending in the circumferential direction toward the directional control valve part side from the starting end of a delivery port arranged in a valve plate, to a length corresponding to an angle formed by the notch groove to the center of a rotary shaft. SOLUTION: A length L1 of a notch 19 corresponds to an angle θ1 (θ1=π/N) when the number of pistons is denoted by N and the ratio of the circumference of a circle to its diameter is denoted by π, to the center of a rotary shaft 6. When cylinders reach the starting end side of a delivery port 17, the pistons reduce, and since pressure oil in the cylinders flows out toward the delivery port 17 side, a flow rate of the pressure oil delivered from a delivery port 17 increases. Here, when the length L1 of the notch 19 is set to an angle θ1 corresponding to an angle of about a half of an angle θ2 between respective cylinder ports 9A, in a half of time necessary every time when the respective cylinder ports 9A communicate with the delivery port 17, the respective cylinders and the delivery port 17 can communicate with each other through the notch 19.

Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To effectively form a ceramic into a ultrafine particle by radiating pulsed laser light with a specified pulse width to an amorphous ceramic.

Title: Control adjustor for supply of gas to burner of boiler or the like
Inventor: JIYOSEFU RU MEERU
IPC: F23N1/02
Filed: 1989-11-15
Abstract: PURPOSE: To ensure a heating output over a wide area, by permitting an opening of the leak valve of a pilot adjuster to follow an air stream passing through a conduit, and providing means for adding to a gas flow separating a pilot adjuster slight opposing pressure which serves as a function of pressure that is existent downstream a leak valve and which changes oppositely to the foregoing pressure. CONSTITUTION: When there is no air pressure at an inlet 11, a valve body 15 is pushed against a valve seat 16 owing to elongation of a spring 9 and a spring 31. A gas valve 3 is pushed against a valve seat 4 to permit no gas flow to be sent from an outlet 2 to a burner U. When an air stream A1 is applied to the inlet 11, the valve body 15 is separated from the valve seat 16, and an air stream A2 is fed out through an outlet 12. The spring 9 is compressed and a leak valve 8 is opened, whereby a gas stream effuses to the outside of a chamber B to reduce gas pressure in the chamber B and hence the gas valve 3 is opened to feed the gas flow G2 to the outlet 2. The more the gas flow A2 is increased, the more gas flow G2 is obtained. Pressure itself acting on the gas valve 32 is adjusted as a function of a gas leakage amount passing through the leak valve 8.  As a result, force of a spring 35 adjustable with a caliburation screw 36 is applied on an upper end of a bar 4 axially.
