Title: Electric rice cooker
Inventor: ISHII NORIO
IPC: A47J27/00
Filed: 1989-03-09
Abstract: PURPOSE:To prevent the infiltration of steam into a case and prevent a failure that a hinge can not be opened or closed by starch by providing a gruel cover having steam blowout ports and stoppers at portions other than the opposite portion to the hinge. CONSTITUTION:A gruel cover 40 made of semi-transparent synthetic resin such as polypropylene, for example, is formed into nearly a square similar to the contour of a case 4, and a knob 41 is protruded at the center. Long groove- shaped blowout ports 42 and semi-circular stoppers 43 are provided on three sides except one side opposite to a hinge 10, a coupling groove 44 is formed on the lower face side of the gruel cover 40, and the collar section of an inner oven is inserted to prevent steam from leaking. When gruel is to be cooked, the gruel cover 40 is covered on the inner oven while a fixed upper cover 1 is kept open. A large quantity of generated steam is blown out in three directions through blowout ports 42 of the gruel cover 40, and no steam reaches the vicinity of the hinge 10. One of the stoppers 43 covers the portion of a receiving metal on the case 4 side coupled with a latch 8, thus the infiltration of steam into the case 4 from around here is prevented.

Title: Production of oxide high-temperature superconductor
Inventor: MORITA MITSURU
IPC: C30B17/00
Filed: 1992-03-13
Abstract: PURPOSE:To obtain an oxide high-temperature superconductor of a large size by effecting the crystal growth of a specific half-molten precursor comprising oxides containing Ba and Cu elements to control the nucleus formation, crystal direction and the growth rate. CONSTITUTION:In an oxide mixture containing Ba and Cu elements where Ba content is 25 to 75mole% (based on the metallic elements), 5 to 50vol.% of RE2O3 (one rare earth element containing Y or a combination of rare earth elements) is dispersed to prepare a precursor. The precursor is once heated at 950 to 1,350 deg.C in an oxidative atmosphere into a half-molten state, then cooled down to 900 to 1,100 deg.C. Then, the precursor is brought into contact with a single crystal as seed crystal of the RE compositional formula having a higher formation temperature than that of the RE composition shown in formula among precursors. Subsequently, the superconductor phase having an arbitrary crystal direction equal to the seed crystal is gradually cooled down in a range of 800 to 1060 deg.C or maintained at a constant temperature between 800 and 1060 deg.C to perform continuous growth of the phase represented by the formula.

Title: Glass substrate for optical master disk
Inventor: MUKODA MASARU
IPC: G11B7/26
Filed: 1990-03-06
Abstract: PURPOSE:To allow the exact evaluation of a pattern shape from a reflection signal of the glass substrate for a master disk by equaling the refractive index of the glass substrate and the refractive index of a photoresist to be applied thereon. CONSTITUTION:The glass substrate for the master disk consists of the photoresist 2 having the refractive index n2 and the glass substrate 1 having the same refractive index n1 as the refractive index of the photoresist 2. For example, 'Photoresist MP1,400(R)' produced by Diplay Far East Inc. is used as the photoresist 2 and a substrate consisting of, for example, 'Barium Flint Glass of code Number BaF 9(R)' produced by HOYA Co., is used as the glass substrate 1. In this case, n1=n2=1.64. There is no boundary between the photoresist 2 and the glass substrate 1 any longer and and an incident light does not make multiple reflections between the boundary of the air and the photoresist 2 and the boundary between the photoresist 2 and the glass substrate 1 in the case of the glass substrate produced by this combination and, therefore, the reflection from the glass substrate is not changed by the film thickness of the photoresist 2.

Title: Ink jet printer
Inventor: IMAMOTO MASAMI
IPC: B41J2/12
Filed: 1985-03-19
Abstract: PURPOSE:To detect the width of deflection of ink droplets accurately and stably, by a system wherein two detecting electrodes are oppositely provided on opposite sides of a path of ink droplets, the difference between electric currents induced in the electrodes due to the passage of an ink droplet is detected, and the deflection quantity of the ink droplet is detected based on the magnitude of the difference output. CONSTITUTION:When the voltage of a charging signal S1 impressed on a charging electrode 3 is V1 which is lower than an optimum value V2, the charge q02 given to the ink droplet is also small, so that the deflecting angle of the ink droplet is small, and the droplet passes through the vicinity of the detecting electrode 82. Therefore, a relatively large current is induced on the electrode 82 side, and an output Sv2 from a current-voltage converting circuit 92 is higher than an output Sv1 from a current-voltage converting circuit 91. Accordingly, by detecting the difference between the output signals Sv1 and Sv2, monitoring the amplitude of an output Sd obtained through a band-pass filter 12 and finding a point at which the output Sd becomes minimum, it is possible to detect the passage of the ink droplet through a midpoint between the detecting electrodes 81 and 82.

Abstract: PURPOSE:To enable discontinuous combustion in gentle acceleration to be prevented, by outputting a fuel cur release signal if the minimum opening of a throttle valve exceeds a preset value or more even in a fuel cut region of small deceleration, in the case of an automobile engine. CONSTITUTION:A throttle valve 2 is returned to a region in the vicinity of a closed position in running operation of a car, and if output torque of an engine decreases to a fuel cut region of small deceleration with the torque being almost below zero, a command means 7, outputting a fuel cut signal, closes a fuel cut valve 4 through a means 8. And then the minimum opening of the throttle valve 2 is stored in a memory means 12. And when the torque is out of the small deceleration fuel cut region or if the minimum opening of the throttle valve 2 even in said region exceeds a preset value or more, a command means 9, outputting a fuel cut release signal, switches the valve 4 to an open position through a release means 11. In this way, the engine promotes the improvement of its fuel consumption further enable discontinuous combustion to be prevented when gentle acceleration is performed in a small deceleration range.
