Title: Silicon carbide heating element
Inventor: TANAKA HIRONAO
IPC: H05B3/64
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To provide a silicon carbide heating element that can improve the temperature distribution inside a furnace that is required for a heat treatment furnace or relax its load and can effectively heat the furnace by changing the temperature on the surface of the heating part of the heating element. SOLUTION: By arbitrarily varying the diameter of a heat generation part of a heating element, surface load density is varied and the surface temperature of the heat generation part 2 is changed. By reducing the diameter of the heat generating part on the terminal sides, the temperature of the terminal sides 1 is set high, so that heat loss from the terminal sides is reduced and the temperature distribution inside a furnace is improved. On the contrary, by increasing the diameter of the heat generating part on the terminal sides 1, the temperature of the terminal sides is set low, so that metal fittings of terminal parts can be protected.

Title: Container cap
Inventor: FUKUMOTO RYOJI
IPC: B65D51/24
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To prevent heat deformation of an inner tube part when using the cap in such a way that it is fitted on a container filled with a high-temperature liquid and maintain sealability, by covering the inside of the inner tube part by the insertion of a protective material into the inner tube part, thereby preventing the direct contact of the high-temperature contents with the inner tube part. SOLUTION: A protective material 3 is inserted on the inside 112, of an inner tube part and an empty space 4 is made between them. Thus, the direct contact of high- temperature contents with the inner tube part 11 is prevented and heat transfer to the inner tube part 11 is made difficult by the empty space 4, therefore the inner tube part 11 is prevented from being deformed inside due to heat even in the case the cap is used in such a way that it is fitted on a container filled with high- temperature liquid, and sealability can be maintained. Further, by making the contact of the inside 112 of the inner tube part with the vicinity of the lower edge of the bottom wall of a discharging tube 17 firm so that airtightness is obtained, the high- temperature liquid does not enter the empty space 4, and the heat transfer to the inner tube part 11 is therefore made more difficult by the heat insulation effect of air in the empty space 4.

Title: Method for driving simultaneous cop exchanger with motor and driving apparatus
Inventor: SAITO YUKIO
IPC: B65H63/08
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To shorten the suspension time of a spinning frame in a cop exchanging work without using an additional inverter for the cop exchanging apparatus. SOLUTION: A cop exchanging apparatus starts the cop exchanging motion when the amount of wound yarn reaches a prescribed level during the operation of a spinning frame. In this case, the motor of the cop exchanging apparatus is driven by a commercial power source and the cop exchanging work is interrupted after the cop exchanging work to extract a full bobbin from a spindle. Thereafter, the power supply to the spindle driving motor of the spinning frame is stopped and the motor is driven by an inverter to supply electric power to the spindle driving motor to restart the cop exchange work. Although the most part of the cop exchanging work is carried out during the suspension time of the spinning frame, the motor is driven at variable speed with the inverter in a state to move a doffing bar at a high speed not to cause the trouble in stopping the doffing bar at a prescribed position.

Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To avoid nonconformity such as increase in an engine rotation speed by judging a variable valve timing mechanism to develop no malfunction, when the valve timing is displaced to a lag side by a prescribed phase or more after starting the engine next time. SOLUTION: When prescribed times A, Bsec are elapsed (S1, S2) with a deviation between a valve timing VTB and a target valve timing VTT being constant and with the valve timing VTB undisplaced, whether the valve timing VTB (old) is a prescribed phase or more is judged (S3), and an advance fail judgment flag XVTFA value is set to 1 (S7). When the valve timing VTB in starting the engine and stalling the engine in the previous time is a prescribed phase or more (S4) and is not a lag fail (S5), a starting advance fail judgment flag XVTFAB value is set to 1 (V6). If the both flags are 1 and the valve timing VTB detected after starting the engine next time is displaced to the lag side by the prescribed phase or more, the variable timing mechanism is judged to develop no malfunction.

Abstract: PURPOSE:To form a good plating layer on a wire to be plated by retreating an operating arm against a spring according to tilting of a two-cell type plating cell in the stage of resetting the two-cell type plating cell from the inclined position to a normal position. CONSTITUTION:The main part of the device is constituted to the two-cell type tin plating cell 14, a supporting device 15, a tilting device 16 and a holder 50 for the wire to be plated. A piston 16a of the tilting device is raised to transfer molten tin to a molten tin dipping part 12 in order to reset the plating cell from the tilted position to the home position. Strikers 58a, 58b attached to the supporting device 16 and the operating arm 53 engage with each other and retreat the arm 52 against the repulsive force of the coil spring 58 thereby spacing a copper wire 22 and a guide roll 54 at a space (d). The above- mentioned strikers contact each other in the case of the opposite operation. A coiler 19 is driven upon ending of the setting of the wire 22 to pass the wire 22 to the dipping part 12. The good tin plating is thus formed to a uniform thickness on the copper wire.

Filed: 1983-12-28
Abstract: PURPOSE:To suppress blooming substantially by controlling so that an illuminating amount of light per prescribed time of a light source for lighting an object will be decreased when levels of signals formed on respective parts of a light receiving face of an image pickup means exceed the prescribed level. CONSTITUTION:After a high band of a dot sequential system output from a senso is cut by a LPF4, it is multiplied by, for instance, a coefficient smaller than one, thereby becoming V3. On the other hand, an output of the LPF4 is integrated, thereby becoming V2. If the V2 is smaller than an V1, an output of a comparator 20 becomes a high level. A delay circuit 32 is outputting a high level signal until the prescribed time expires after an output of the comparator 20 rises and falls, and for this time a switch 20 is set to on. A comparator 23 compares the output V2 with the coefficient circuit output V3, and when V2<V3, it outputs a high level signal, which is supplied to a radiation characteristic control circuit 21a through a delay circuit 33, and controlled so that an emitting time to obtain almost the same emitting amount of light will be prolonged and illumination will be averaged in terms of time.
