Title: Electromagnetic cooking pan
Inventor: HASHIZUME KIMIO
IPC: A47J36/02
Filed: 1994-09-28
Abstract: PURPOSE: To increase the heating value, and to improve the heating efficiency by using titanium or titanium alloy as the metal material forming the inner surface layer of a pan, and furthermore, using magnetic metal material as the metal material forming the outer surface layer of the pan. CONSTITUTION: A pan main body 10 is formed into the double-layer structure of clad, and the pan inner surface layer 1 is made of titanium or titanium alloy, and the pan outer surface layer 2 is made of magnetic metal material such as magnetic stainless steel. The surface of the inner surface layer 1 is formed with a film 3 such as titanium oxide film or titanium nitride film at need. Since this titanium oxide film does not need the film coating or the special heating, the pan main body 10 can be manufactured by superplastic processing or hoot forging. This titanium or titanium alloy has the performance for appropriately relaxing the heat conduction to the food, and furthermore, since it has a small heat conductivity and a small density, it is appropriate for the material forming the inner surface layer.  Furthermore, titanium and titanium alloy is a heater, which receives the induction heating work by the high frequency current and which heats efficiently, it is excellent for the metal material forming the outer surface layer 2.

Title: Low temperature show case
Inventor: TAMAYAMA KOJI
IPC: F25D17/08
Filed: 1989-09-08
Abstract: PURPOSE:To facilitate a fixing of a transparent plate and further to facilitate a fixing operation for a bumper rail by a method wherein a wall front surface is provided with a rising part in contact with the lower part of an inner surface of the transparent plate and the bumper rail is provided with a pushing part in contact with a lower portion of an outer surface of the transparent plate and a resiliency applying part. CONSTITUTION:As a lower part of a transparent plate 41 is arranged between a rising part 30 and a pushing part 38 of a bumper rail 33, a resiliency applying part 37 of the bumper rail 33 is deformed. As this deformation occurs, a resilient force is transmitted to the pushing part 38, and then a force for pushing the lower portion of the transparent plate 41 toward the rising part 30 is acted upon with the pushing part 38. Due to this fact, the transparent plate 41 is fixed between the bumper rail 33 and the rising part 30 and at the same time the bumper rail 33 is also fixed. Accordingly, it is sufficient if only the lower part of the bumper rail 33 is fixed with small screws. A mere insertion of the transparent plate 41 between the rising part 30 and the pushing part 38 is sufficient and thus its fixing operation can be simply carried out.

Title: Tape and cassette for security of copyright
Inventor: NISHIYAMA KAZUHIKO
IPC: G11B23/087
Filed: 1988-09-20
Abstract: PURPOSE:To erase and reproduce the content of video recording automatically by devising the protection such that a magnet traces a tape or not through the utilization of the thickness of the tape wound on a reel in the magnet devised to be able to trace the tape wound on the reel. CONSTITUTION:In the case of reproducing a tape, suppose that the tape is wound from a reel A to a reel B, then the content of video recording is erased by magnetism of a plate magnet C and cannot be reproduced. When the tape is entirely wound on the reel B, the thickness of the wound tape is thicker, and the magnet C is fixed at the position of a magnet C' while being hooked by a crank shaped claw on the way of the guide plate of the plate magnet while tracing the tape and video recording and reproduction is enabled. When a button E is depressed, the guide plate D is pushed from the outside of the tape cassette to release the magnet C' from the claw of the guide plate D. Thus, video recording is automatically erased when the recording is once reproduced.

Abstract: PURPOSE:To maintain the function for holding a constant voltage even if negative noises enter into a neighboring region and a parasitic transistor is conducted, by surrounding an n-type region in contact with the cathode electrode of a Zener diode with a p-type region, and blocking the connection with the parasitic transistor. CONSTITUTION:On a p-type silicon substrate 1, a high concentration n-type region 2 and a high concentration p-type region 4 are formed. Then, impurity ions are implanted, and a p<+> type region 5, n-type regions 6 and 72 and a p-type region 7 are formed. A p-type region 71 is formed so as to surround the n-type region 6. Even if a parasitic transistor 11 is conducted, the function of the device can be maintained when a current, which is supplied from a cathode 8 of a Zener diode Z is made to flow to an anode 9 continuously. The n-type region 71, which is connected to the cathode 8, is surrounded with the p-type region 71. Thus the outflow of the voltage, which is supplied to the cathode 8 to a collector 3 of the parasitic transistor 11 is prevented.

Abstract: PURPOSE:To facilitate setting of control center for focus control based upon the just focus state of a recording light beam by a focus servomechanism, by providing an objective unit which includes an objective and a driving means for focus control that drives the objective. CONSTITUTION:A command signal S9 is supplied from the 3rd output terminal O3 of a central processing circuit 19 to a driving circuit 43 and a stepping motor 44 moves a photodetector 13. When the photodetector 13 moves, return beams of a light beam for detection which is incident equally to two photodetecting elements so far and returned from a recording medium 1 are not incident equally to both photodetecting elements any more. Consequently, the difference signal S5 from a subtracting circuit 20 varies in level and a driving current (i) based upon the difference signal S5 flows through the driving means 6 for focus control to drive the objective 5, which is moved to the position where the return beams of the light beam for detection from the recording medium 1 are incident equally to the two photodetecting elements of a photodetector 13.

Title: Cross member of frame for vehicle
Inventor: SANNOMIYA NOBUO
IPC: B62D21/02
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a cross member of a frame for vehicle capable of reducing the investment on a die and improving the torsional rigidity and the durability. SOLUTION: A gusset 22 formed by bending a blank 20x in the direction orthogonal to a cross member body 21 is integratedly provided with a member body 21 on each end part of the cross member body 21 of U-shaped section formed by bending the flat blank 20x. Because the flat blank 20x is bent to integrate the gusset 22 with the cross member body 21, only a die for the blank 20x may be prepared, and the investment on the die can be reduced. Further, the assembly process to assemble the gusset 22 with the cross member body 21 can be dispensed with to reduce the cost. Because the gusset 22 is continuously integrated with the cross member body 21, the input applied to the gusset 22 is transmitted to the member bandy 21 through its continuous part, and the durability can be improved.
