IPC: H03K19/0948
Filed: 1993-09-01
Abstract: PURPOSE:To shorten delay time when a load capacity becomes large by connecting diodes between the high potential power source of a differential amplifier circuit and the common source of plural driving transistors. CONSTITUTION:Input signals Vin are provided with the amplitude of -0.8-1.6V and when the built-in voltage of the diodes D1 and D2 is set at 1.6V, the voltage of the connection point of the common source of nMOSFETs 21 and 22 and a constant current circuit PS is fixed at 1.6V. In this case, when the value of a load element Z is adjusted and the threshold value of the FET 21 is set at 0.8V, it becomes the same as the voltage of the signals Vin, a current is not made flow to the FET 21 and the signals of the bar of the output signals Vout become '0'. Also, when the signals Vin are -1.6V, the signals of the bar of the signals Vout become -0.8V and the high level of the output signals of the differential amplifier circuit coincides with a high potential level. Then, logic can be surely attained in a short time with a small amplitude logical operation.

Title: Traction lot
Inventor: YAMAMOTO TAISUKE
IPC: H02G1/02
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To restrain increase in traction force, while the front end of a cable is being passed through a safe in cable installation work. SOLUTION: In a traction lot 20, one-side ends of a plurality of strands 22a to 22e different from each other in length are arranged and bound so as to be uniform, and the bounded ends are crimped by a nut 23. The other-side ends are formed with a ring 21, and its entire body is covered with a casing 24. The nut 23 is screwed into a bolt 32 of a cable front edge 31, and the ring 21 is tied with a traction rope termination 11 for cable installation work. The front end of the traction lot 20 has low rigidity because of the small number of strands, however, the number of strands is more and the rigidity also becomes larger as it approaches the termination. An angle α2 of a cable front end 31 to the horizontal decreases with a change in the rigidity and becomes almost horizontal, when it enters a safe 50a. When the angle α2 to the horizontal is large, the rigidity becomes small. On the other hand, since when rigidity is high, the angle α2 to the horizontal becomes small so that it is possible to minimize tension which is required to increase because of the cable front end 31 passing through the safe 50a.

Title: Electric cooker
Inventor: AOTO KAZUYOSHI
IPC: A47J27/08
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To prevent high pressure steam from being discharged suddenly into the atmosphere even when a pressure release valve is opened by external operation while the interior of a pot is in a high pressure state by making the opening area of a by-pass port provided in the pressure release valve smaller than the opening area of a steam release port. SOLUTION: When a by-pass port 23 is opened, high pressure steam in a pot is discharged into the atmosphere from a steam release port 38 through the by-pass port 23, an insertion hole, a space 37, a clearance 34 and a steam guide cylinder 33. At this time, pressure in the interior of the pot enters a wide space 37 at a breath from a small by-pass port 23, slightly lowering the pressure. Pressure to be discharged, however, lowers from the steam release port 38 whose opening area is large, and is scattered into the atmosphere. That is, high pressure steam in the pot enters the space 37 in a high pressure state from the by-pass port 23, slowed in the space, discharged from the steam release port 38 whose opening area is larger than the opening area of the by-pass port 23 without converging high pressure steam.
