Title: Housing chamber for liquefied metal handling equipment
Inventor: KUROKAWA MASAO
IPC: G21C9/00
Filed: 1978-05-22
Abstract: PURPOSE: To minimize the exothermic reaction of a liquefied metal, by arranging  breakable sheets edge to edge at the top of a receiving pan provided at the bottom  of a housing chamber so that the liquefied metal having leaked is insulated from  the upper atmosphere as much as possible.  
     CONSTITUTION: The top opening of the receiving pan 1 is entirely covered with the thin sheets 7. If the liquefied metal 9 gushes and falls, the thin sheet 7 for a section corresponding to the falling liquefied metal is broken and the metal flows into the receiving pan 1 and spreads therein. However, the other thin sheets 7 are intact. If the number of openings of a frame 4 is set at 50 to 100, the broken area is 1/50 to 1/100 of the total area and the surface of the liquefied metal 9 is almost insulated from the upper atmosphere 10.

Title: Induction heating cooker
Inventor: IWAI TOSHIAKI
IPC: H05B6/12
Filed: 1990-03-12
Abstract: PURPOSE:To improve accuracy for timing to detect water boiling by detecting the absolute value of the temperature of a heated object, and the variation of the aforesaid temperature, and controlling the output of induction heating, depending upon respective detected output values. CONSTITUTION:A heating coil 2 connected to a power supply 1 heats an object or pan 3 so placed as to oppose thereto, via induction heating. In this case, the power supply 1 may be a commercial power supply, but a high-frequency power supply using an inverter or the like may provide higher induction heating efficiency. The output terminal of a temperature sensor 4 is connected to the first and second temperature detection means 6 and 7, and output from the aforesaid means 6 and 7 is applied to an output control means 8. Thus, this output control means 8 regulates output from the power supply 1. Also, heating is performed with strong thermal power until water temperature reaches a certain level. When the prescribed water temperature is attained, the output is reduced to restrain a water temperature rise, and water boiling is detected after the follow-up of a temperature sensor 4, thereby embodying high accuracy for water boiling detection.

Title: Voltage regulator circuit and voltage regulating method
Inventor: BORDEN ROBERT B
IPC: G05F3/24
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain a voltage regulator with a low dropout by adding a pull- down circuit which is connected to an output node. SOLUTION: The pull-down circuit PD1 includes a comparator C1 , trip voltage VTRIP, and a pull-down transistor MPD. When an overvoltage state is present so that the load current ILOAD of the regulator varies quickly from a large value to nearby zero, the output voltage of an amplifier A1 rises exceeding Vtrip , and consequently the transistor MP1 is cut off, so that the output of the comparator C1 falls almost to the ground voltage. When the output of the comparator C1 falls down to the ground voltage, the transistor MPD enters a linear area to lead a current of several mA out of the output of the regulator, and the output voltage of the regulator is adjusted by being put back by several μs. Once the output voltage is adjusted, the output of the comparator C1 becomes high to turn off the transistor MPp, and the regulator is put back to its normal operation.

Title: Trim end engaging structure of seat
Inventor: KUSHIYAMA TOMOYA
IPC: A47C31/02
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To eliminate inconvenience such as exposing an engaging tool caused by rotation of the engaging tool, losing tension of a trim, etc., to improve the appearance, by forming a bend part to be bent into the inserting direction of the engaging tool onto an engaging wire to stop rotation of the engaging tool by the bend part. SOLUTION: A bend part 3c to be bent into an almost reverse U-shaped toward the inserting direction (upward) of an engaging tool 4 is integrally formed in a proper length on the lower part 3b of an engaging wire 3 at an almost middle part in the longitudinal direction. The bend part 3c can be simultaneously formed when a straight wire is bent into a lateral rectangular frame shape to make the engaging wire 3. A trim 2 is covered on a cushion frame 1 and the engaging tool 4 is inserted into the lower part 3b of the engaging wire 3 from under side to engage the trim 2 by drawing the trim 2 downward. Even though rotation force (b) acts on the engaging tool 4 by the drawing reaction force of the trim 2, the engaging tool 4 is not rotated since rotation of the engaging tool 4 is stopped by the bending part 3.

Title: Optical disk recording/reproducing device
Inventor: UDAGAWA TOSHIKI
IPC: G11B7/085
Filed: 1992-02-18
Abstract: PURPOSE:To limit a scanning range to some extent and to shorten a scanning operation time by moving in advance an objective lens to a target value, at the time of focusing scan. CONSTITUTION:When an operating command is received from an integrated controller, a disk jump control part 11 gives a command and an address to a target value holding part 12 and switches a switch 14, and switches a switch 13 by another controller. To one disk, a signal FS is generated from a focusing signal generator 10 and a lens is moved. By a leading-in range detector 9, a possible range is detected, and recorded in a RAM 12a through the switch 13 at the time of focusing. To the other disk, the range is recorded in a RAM 12b in the same way. On the other hand, when a disk jump is executed in the course of reproduction, the control part 11 switches the switch 14, and for instance, reads out a target value SM from the RAM 12b and holds it, supplies it to an actuator driver 6, and a lens is moved into a leading-in possible range. A focusing servo loop is formed, a servo operation based on a focusing error signal is executed, and the time required for a focusing servo start operation is shortened.

Filed: 1984-03-30
Abstract: PURPOSE:To form a long seamless unequal twisted chip easily by extruding a flat chip specified distance from a forming die having an unequal twisting groove and stopping without passing through the die. CONSTITUTION:A flat chip of sintered hard alloy is put in the linear groove 2 of a twist forming die 1 and extruded to a twisting groove 3 by a punch 4, and the extruding of the punch 4 is stopped at a position of the groove 3 at which a specified angle of torsion can be obtained. A part that plastic deforms the flat chip profiling the groove 3 is heated by a high frequency coil 5 to 1,000- 1,200 deg.C at which the flat chip can obtain sufficient capacity of deformation and material defects such as growth of particles etc. After plastic deforming the flat chip by the groove 3, the power source of the coil 5 is cut off, and released from a mold when the temperature of the chip becomes below 500 deg.C. It is necessary to divide an outliner 6 beforehand to make this releasing. By this method, manufacture of a long, seamless unequal twisted chip in which changing angle of torsion continues becomes possible, and the accuracy of torsion of each part of the chip is high.
