IPC: B29D30/24
Filed: 1984-08-29
Abstract: PURPOSE:To enable change in expansion of a drum diameter, by a method wherein a cylinder mechanism sliding in the direction of an axis of the drum is connected with a drum segment through a link and a slide bar sliding by a cylinder mechanism is provided with an advance position control mechanism, in a molding drum for a tire and belt. CONSTITUTION:When compressed air is fed to a rear chamber 32 of a cylinder mechanism 20 through air passages 36, 37, 26, 38 of a main shaft 10, a piston 23 is moved backward, abutted against a flange 13 of a drum shaft 12 and stopped. In this instance, a drum segment 18 is guided to a slide 17 and is slided inside in a radiusward direction through a link mechanism 40 by a rod 28 of a driving sleeve 27. When compressed air is fed to a front chamber 31 of a cylinder through air passages 33, 34, 35, the piston 23 is advanced, a slide bar 52 is abutted against a stopper 72 through the rod 28 and stopped and the segment 18 is slided outside in the radiusward direction.

Title: Tachometer
Inventor: ASANO ICHIRO
IPC: G01P3/48
Filed: 1990-07-07
Abstract: PURPOSE:To enable highly accurate measurement with high responsiveness by a method wherein a circuit is provided to sample and hold an output of a circuit which integrates a pulse signal and the output of the circuit is fed back to an integration circuit. CONSTITUTION:A pulse (a) proportional to revolutions to be inputted via an input terminal 1 is shaped into a pulse (b) with a waveform shaping circuit 2 and the pulse (b) is inputted into a one-shot multivibrator 3 to make a pulse signal (c) having a fixed voltage and a fixed time range. The signal (c) is integrated with an integration circuit 4 and an integration output (d) is held with a sampling/holding circuit 5. But an output (e) of the circuit 5 is fedback FB to the circuit 4 and hence, the output (d) decreases gradually. Then, when the signal (c) is inputted, the output (d) increases and the output (e) increases. When this operation is repeated as each signal (c) is inputted, an increment portion of the signal (d) by the inputting of the signal (e) balances a decrement portion of the signal (d) as given by the FB from the circuit 5 to maintain the output (e) at a fixed value thereby enabling the obtaining of an output voltage proportional to the revolutions.

Title: Driving method of bubble memory device
Inventor: OOTA HIROBUMI
IPC: G11C11/14
Filed: 1983-09-30
Abstract: PURPOSE:To attain a large bias margin at a low power consumption by increasing the strength of a rotating magnetic field driving a bubble memory chip at the function gate operation of the bubble memory chip. CONSTITUTION:The rotating magnetic field is increased temporarily when a bubble passes through a gate section and the period when the rotating magnetic field strength is increased is taken as <=5 cycles before and after a pulse is given to the function gate. For example, while the strength of rotating magnetic field at the swap operation is 50Oe, the strength of rotating magnetic field is 70Oe between 25mus and 45mus. As a result, the bias margin is frightened from 20Oe (conventional method) into 27Oe. Since the duty of a swap pulse is <=2% even at the write operation, the chip temperature rise due to the increase in the rotating magnetic field at a time does not take place.

Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To easily obtain the hardness according to the facility of a bearing, etc., and to unnecessitate processes of a stress relief annealing and washing, etc., by cooling a thin sheet parts with gas after carburizing in a carburizing chamber. SOLUTION: A work completing the carburization is quickly shifted to a pressurized cooling chamber, and at the same time, the inert gas, e.g. nitrogen gas, etc., is flowed into the cooling chamber to execute the pressurization. The work is cooled while stirring the inert gas with a propeller. By this method, the cooling speed is slower than the case of hardening with liquid and can easily be controlled by adjusting the gas pressure and the kind of gas. Therefore, the hardness is given to the work according to the facility and the use and the development of strain caused by the heat treatment can be restrained. Further, it is unnecessary to wash the liquid stuck to the work, such as the hardening with the liquid. In such a way, the processes of the stress relief annealing and the washing are unnecessitated, and the saving of the treating processes of the work can be obtd.
