Title: Internal-combustion engine
Inventor: KIZAKI YOSHIO
IPC: F02B31/02
Filed: 1982-12-14
Abstract: PURPOSE:To improve the condition of gasified fuel and to prevent knocking by improving positions where intake valves, an exhaust valve and an ignition plug are arranged. CONSTITUTION:In low load running, mixture flows only in an intake port 14 and is introduced into a combustion chamber 4 through a first intake valve 7 to produce a swirl. And the mixture introduced into the combustion chamber 4 through the first intake valve 7 flows first in the direction of an exhaust valve 19 so that most of fuel components in the mixture contact the high temperature exhaust valve 19 to promote gasification. In low speed high load running, since a mixture amount is large and most of fuel flows in liquid stage, fuel injected from the first intake valve 7 into the combustion chamber 4 collides with the high temperature exhaust valve 19 to cool it for preventing knocking.

Title: Measuring device of temperature of metal surface
Inventor: TANAKA HITOSHI
IPC: G01K7/36
Filed: 1982-12-16
Abstract: PURPOSE:To measure a temperature accurately without the influence due to the variance of the distance between a detecting coil and a metal surface, by separating the output of a high frequency bridge circuit having the detecting coil as one side into temperature components and distance components and correcting temperature components on a basis of distance components. CONSTITUTION:An eddy current generated on the surface of a metal such as a roll 1 is changed in accordance with temperature, and the impedance of a detecting coil 2 constituting one side of the high frequency bridge is changed by the magnetic field due to this eddy current. The unbalance output of this bridge circuit is processed by phase detectors 24 and 26 and is separated to distance components between the coil 2 and the roll 1 and surface temperature component of the roll 1. The sensitivity change rate of a ratio of distance components stored in an analog memory 32 to distance components for a reference distance is determined, and temperature components of the same change rate are corrected with the sensitivity change rate of distance by an analog computer 34, and thus, the temperature of the metal surface is accurately measured easily without the influence due to the variance of the distance between the detecting coil and the metal surface.

Filed: 1990-08-22
Abstract: PURPOSE:To make it possible to operate a winder upto the maximum specified winding roll diameter in any case by operating the area of overwinding which occurs during deceleration of a winding roll and then operating the area corresponding to the maximum specified roll diameter thereby operating the deceleration starting timing. CONSTITUTION:A rewind roll diameter operating unit 9 operates the thickness of paper based on the rewind roll diameter which is operated every moment. An operating unit 15 then operates the area C of overwinding of a winding roll, which occurs during deceleration after provision of a stop command before stoppage, based on the paper thickness, a deceleration time set by a deceleration time setter 10, and a winding speed set by a winding speed setter 17. An operating unit 12 then operates the area A of roll diameter DMAX m<2> set by a maximum winding roll diameter setter 16 and a command for stopping the winder at the roll diameter DMAX is inputted thus determining the deceleration starting diameter by subtracting the area C from the area A. Deceleration is started at a time point when such a diameter is reached.

Title: Electric connector
Inventor: MATSUNUMA HIROYOSHI
IPC: H01R13/518
Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To provide an electric connector whose shell is not deformed even if it is wrenched when a mating connector is inserted by arranging guide parts in the width directional center where connecting parts of a contact project, and sandwiching a fixing part and a fixing leg part of the shell by the guide parts. SOLUTION: In the almost center on the side where connecting parts 22 of a contact 14 of an, insulator 12 project, two guide parts 34 project toward the fitting port 40 side by putting mating faces of a shell 16 symmetrically. These guide parts 34 can sandwich a fixing part 36 and a fixing leg part 26 of the shell 16, and are better to be larger by about 0.1 to 0.4 mm than the fixing part 36 and the fixing leg part 26. Therefore, when a mating connector is inserted, since a plate-like piece 18 of the shell 16 reliably engages with a hitching part of the insulator 12, even if force of about 6 kg is applied, the shell 16 is not deformed. Since the fixing part and the fixing leg part arranged on both sides of the mating faces of the shell 16 are sandwiched by the guide parts 34 of the insulator 12, the shell 16 does not open when the mating connector is inserted.

Abstract: PROBLEM TO BE SOLVED: To precisely judge and deal with an abnormal increase in the concn. of dil. brine in a dil. brine tank due to the leakage of concd. brine without wasting generated electrolytic water. SOLUTION: The dil. brine in a tank 20 is supplied to an electrolytic cell 30 by an electric motor 28 and electrolyzed in the cell 30, the acidic and alkaline ionized waters (electrolytic water) are transiently stored in both tanks 40 and 50, respectively, and the acidic water is discharged from a cock 42 at need. The level of the dil. brine is kept almost constant in the tank 20 by supplying water from the outside, and the concn. of dil. brine in the tank is also kept constant by replenishing concd. brine from a tank 10. When the level is raised in the acidic ionized water tank 40, the generation of electrolytic water is suspended, and, when the level in the tank 40 is lowered, the generation of electrolytic water is resumed.  The generation or electrolytic water is stopped when the dil. brine concn. is abnormally increased in the tank 40 while the electrolytic water is generated or the generator is on standby.

IPC: H01L21/8234
Filed: 1992-08-20
Abstract: PURPOSE:To constitute a semiconductor storage device which enables multilevel storage, at least three-level storage, and thereby improve the storage capacity. CONSTITUTION:The Hall terminal 1 of a Hall bridge type MOS FET M1 is connected to the gate electrode of a MOS FET M2 of the same type and the Hall terminal 2 of the MOS FET M2 is connected to the gate terminal of the MOS FET M1 with the wirings crossing each other. Depletion type MOS FETs D1 and D2 are connected between the MOS FET M1 and its power supply and between the MOS FET M2 and its power supply, respectively. A strong magnetic field is generated in a direction perpendicular to the gate electrodes in a cooled condition obtained by means of liquid helium. This extremely reduces the power consumption because the quantum Hall effect reduces the resistance between the source and drain virtually down to zero.
