Title: Detection of penetration of liquid into liquid distributing container
Inventor: TOOMASU KURIFUTON JIESOTSUPU
IPC: G01N1/00
Filed: 1985-07-19
Abstract: Apparatus and a method are described which permit the detection of penetration of liquid by an apertured container (30) used for aspirating and dispensing the liquid. The apparatus and method feature control means (80) for advancing the container an increment of the maximum possible distance to the liquid; generating a pressure differential within the dispensing container that is sufficient to generate a signal that is indicative of whether the container aperture is closed by the liquid; detecting and signaling the pressure produced within the container by such a pressure differential; and comparing such signalled pressure against a reference value determinative of whether the container has penetrated the liquid.

Title: Manufacture of laminated core of motor
Inventor: ISAYAMA MINAO
IPC: H02K15/02
Filed: 1993-06-04
Abstract: PURPOSE:To expand a draft with a flatness of a board being maintained and to punch a stator iron core piece and a rotor iron core piece, each having a small air gap, to the desired shapes by pressing narrow sections of pole teeth of the stator iron core piece in the thickness direction of the board to make them thin and expand to the rotor iron core piece punched side and then by punching small teeth of an end part of the pole teeth and the external shape and by stacking. CONSTITUTION:From a metal thin board 1 after a rotor iron core piece 5 having a lot of teeth 6 around is punched out, pole teeth 7 of a stator iron core piece 15 is so punched out that each pole tooth may has a narrow part. Then, the narrow parts 8 are pressed in the thickness direction of the board to be made thin and end sections 9 of the pole teeth are extended toward the rotor iron core piece 5 punched side and a draft is expanded while an air gap is kept minimum. The draft is expanded by pressing part of the flat pole teeth 7 and by extending it as it is flat, and there is no distortion in the shape such as a swell. Since part of the pole teeth 7 is made narrow, the pole teeth 7 expand in the width direction when the narrow part is pressed thin. However, the thin part 11 is narrow and so, there is no projection and winding can be done with a good workability and without damaging an insulating layer.

Title: Electric heat built-up water heater utilizing frictional heat
Inventor: TANIYAMA KEISUKE
IPC: F24J3/00
Filed: 1987-06-27
Abstract: PURPOSE:To obtain a compact and economical water heater, by constituting the heater in such a manner that an inner body fitted on a rotary shaft and an outer body as an outer cylinder are rotated by a drive motor, frictional heat by contact is built up, and the heat is radiated directly into water or the like. CONSTITUTION:A rotary shaft 4 is rotated through a heat insulating joint 7 by a drive motor 6 fitted on the bottom of a frictional body 1 as an outer cylinder, and the upper and the lower, two sheets of inner frictional bodies 2 connected by a through hole and wedge pieces 3 are rotated all together. Then a force which moves the pieces 3 to the outside acts by centrifugal force, and by that force the upper and the lower, two sheets of inner frictional bodies 2 are pushed wide to the outside, that is, to the upper and the lower sides. Then friction by contact of the upper and the lower surfaces with the frictional body 1 as an outer cylinder is produced by revolution, and heat is built up. By utilizing this heat as well as to utilize centrifugal force, frictional resistance at the starting time is low, so that a powerful drive motor to make the start easy is not needed. Once revolution is started, it can be continued constant by the moment of inertia of inner frictional bodies 2 and the revolving force of a motor 6, and frictional heat is built up continuously.

Title: Automatic threshold value adjusting circuit
Inventor: MURAKAMI NORIO
IPC: H04J1/00
Filed: 1984-07-31
Abstract: PURPOSE:To expand an operating range of an automatic threshold value adjusting circuit by preventing an output signal of an amplifier amplifying an input signal from being clamped at large signal input. CONSTITUTION:When an input voltage VA of a comparator COMP is a VBE (where; VBE is a forward voltage drop of each diode) or below, that is, when an output voltage Vo of the amplifier AMP is <=2VBE, the gain of the amplifier AMP is -(R0/R1). When the input voltage VA is the VBE or below, that is, the output voltage Vo of the amplifier AMP is larger than 2VBE, the feedback resistor of the amplifier is changed to R0//R3, the gain of the amplifier AMP is -(R0//R3)/R1 and then the gain of the amplifier is lowered. Thus, the amplitude range of the input signal until the upper part of the output signal VA of the amplifier AMP is clamped is expanded.

Filed: 1993-06-30
Abstract: PURPOSE:To increase strength and coefficient of elasticity, and maintain an excellent appearance as an artificial marble by forming a fiber-reinforced resin layer internally and providing an artificial marble layer externally. CONSTITUTION:A pillar-like hollow molding has an internal fiber-reinforced resin layer A and an external artificial marble layer B.

IPC: E04B2/56
Filed: 1993-06-30
Abstract: PURPOSE:To provide wall panel-fastening construction which is simple and by which the work of sinking heads of screws for fastening wall panels and the work of caulking a joint part can be omitted. CONSTITUTION:The edges of two wall panels 2, 2 are opposed to each other, leaving a gap G between them, and are located along the front of a column 1, and finally are fastened to the column 1 with screws 3. Recesses 5 each are preformed on the edges of the wall panels and the screws 3 each are screwed on the insides of the recesses 5. A gasket 4 is pressed-in from above the screws 3 so as to be fitted between the recesses 5 and the gap G. Since the heads of the screws 3 are hidden in the gasket 4, finishing works such as puttying and touching-up are unnecessary. Since the work of sealing a joint and the work of sinking the screw heads are simultaneously done with the gasket 4, the works of puttying and silicone caulking are dispensed with and such a trouble that a puttying material and a caulking material are discolored with the passage of time does not occur. The work of fitting the gasket 4 is simpler than the works of puttying and caulking, and labor and time therefor can be omitted.

Abstract: PURPOSE:To minimize influence given to the transmission function of LAN by changing the state of a blocking port connected to same LAN as a root port to a forwarding state when time is out at the time of receiving BPDU to make the port of the designated bridge of LAN comes to a blocking state. CONSTITUTION:The time-out of C=BPDU is detected at high speed by using the fact that two ports 3-7 and 3-8 have compatibility on a topology when the two ports 3-7 and 3-8 of the designated bridge 3-4 are connected to same LAN. Namely, the reception stop of C=BPDU of the port 3-7 occurs when a fault occurs in the part of a transmission line 3-10. But, the reception of the blocking port 3-8 continues. In such a case, the state of the port 3-8 is set from the blocking state to the forwarding state and the root port of the bridge is changed from 3-7 to 3-8.

Abstract: PURPOSE: To obviate the entry of slag, etc. mixed in molten metal into cavity by providing the inlet of the runner for directing molten metal from an injection sleeve to the die cavity in the position excluding the upper part of sprue core.  
     CONSTITUTION: Where a stationary die 4 and a moving die 7 are held closely contacted, the female type tapered part 5b of an injection sleeve 5 and the male type tapered part 8a of a sprue core 8 are firmly fitted together. Hence, if molten metal 11 is supplied into the spacing 1 in the injection sleeve and the molten metal 11 is extruded from the spacing 1 by a plunger 13, it is pressure-fed into cavity 14 through a runner 12. The impurities 16 such as slag etc. in the molten metal 11 are lighter than the molten metal 11 and therefore they float to the upper part of the spacing 1. However, the runner inlet 12a is provided within the range excluding the bow-form part corresponding to the center angle of 30° with the perpendicular passing the center of the sprue core in-between and therefore, the entry of the impurities 16 in the runner 12 is obviated.
