Inventor: KAMIYA TAKUMI
IPC: H03F3/45
Filed: 1992-04-09
Abstract: PURPOSE:To obtain the buffer circuit able to prevent the oscillation effectively without forming any capacitor onto an integrated circuit.

Title: Driving mechanism for wheel spindle stock in grinding machine
Inventor: SAITO YUICHI
IPC: B24B47/12
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent a wheel spindle stock from being vibrated by restraining a feed screw from being deflected when the wheel spindle stock is in feed operation at high speed, and thereby properly grind a work. SOLUTION: A wheel spindle stock 15 is mounted to the upper part of a stationary base fixed to a bed 11 by way of a static pressure sliding mechanism 16. The shaft parts 25a and 25b at both the end parts of a feed screw 25 are supported by brackets 21 and 22 integrally formed in the stationary base by way of a radial bearing 23 and a hydrostatic bearing 24. A nut member 32 fixed to the lower surface of the wheel spindle stock 15 is threadedly engaged with the screw part 25c at the intermediate part of the feed screw 25. Since one shaft part 25b of the feed screw 25 is supported by the hydrostatic bearing 24, even if the feed screw 25 is pushed upward, or pressed downward, action force is absorbed by the hydrostatic bearing 24, the feed screw will never be elastically deformed, and thereby it will never be deflected.

Title: Formation of polysilicon film
Inventor: FUSE MARIO
IPC: H01L21/20
Filed: 1990-04-03
Abstract: PURPOSE:To shorten an annealing time and to lower a threshold voltage by a method wherein a part into which silicon ions are to be implanted and a part into which the silicon ions are not to be implanted are divided on an amorphous silicon film, the silicon ions are implanted and a heat treatment is executed. CONSTITUTION:When silicon ions are implanted into an amorphous silicon film, an ion-implantation-preventing film is formed or the irradiation of an ion beam is controlled. Thereby, the ions are implanted excluding a specific part in order to prevent the number of nuclei from being reduced at the interface between the amorphous silicon film and a substrate. Grains of polysilicon grow in the film-thickness direction and in a direction parallel to the film. However, the growth speed in the film-thickness direction is larger. As a result, a silicon nucleus density is high in a part into which the ions have not been implanted; the distance between adjacent silicon neclei becomes short; polysilicon whose grain size is small is formed. The growth of grains is slow in a part into which the ions have been implanted; the grains into which the ions have not been implanted act as the center and grow until they meet grains which have been grown from the region of an adjacent implantation-preventing film. A growth operation is started simultaneously with a heat treatment, and a growth time is shortened.

SOLUTION: The noncontact type data carrier 10 is equipped with an oscillation circuit 17 which oscillates a pulse signal of specific frequency higher than a power supply signal, a counter circuit 16 which counts a pulse signal in one cycle of a received signal from the reader writer 50, and a comparing circuit 18 which compares one-cycle length of the receive signal obtained according to the count result of the counter circuit 16 with the previously set one-cycle length of the power supply signal and judges that the received signal is a modulated signal when the length is different from that of the power supply signal. When the received signal is the modulated signal, the received signal is demodulated.

IPC: H04N5/92
Filed: 1985-04-26
Abstract: PURPOSE:To record and to reproduce suitably a composite video signal and a sound signal without interfering mutually with an address signal by constituting a device so that the composite video signal which is FM-modulated is not recorded overlapping on an address signal area and also setting the frequency band area of the address signal higher then that of a modulated sound signal. CONSTITUTION:A means 2 which FM-modulates the composite video signal, means 16-22 which control the rotation phase of a disk so that the vertical blanking period of the composite video signal is recorded on a prescribed position including the address signal, a means which modulates the sound signal to the signal having a lower frequency band area than that of the FM-modulated composite video signal and a means 3 which mixes the FM-modulated composite video signal and the modulated sound signal are provided. Furthermore, with providing a means 23 which prevents the composite video signal that is FM-modulated from being supplied for a prescribed time to the mixing means 3 so that the FM-modulated composite video signal is not recorded at the area where the address signal is performed, and providing means 11-13 which record the signal outputted from the mixing means 3 on an information recording truck, the address signal is set as the signal having a higher frequency band area than that of the modulated sound signal.

Title: Flowrate control device
Inventor: KIDOUCHI YASUO
IPC: F16K31/06
Filed: 1989-04-07
Abstract: PURPOSE:To simplify constitution by providing the first magnet as a pressure receiving body, the first spring for energizing the pressure receiving body, a pilot valve for opening and closing the communication hole of the pressure receiving body, the second spring for energizing the pilot valve, the second magnet having different polarity from the first magnet, and a variable magnetic force generation means, respectively. CONSTITUTION:When power is not supplied, a pilot valve 20 closes a communication hole 16 with the second spring 22, and pressure difference between a back pressure chamber 14 and a primary chamber 13 disappears. As a result, a valve body 11 comes in contact with a valve seat 18 with the first spring 19, thereby stopping a flow. When a coil 25 is supplied with power, the second magnet 21 is adsorbed and the pilot valve 20 opens the communication hole. Consequently, pressure in the back pressure chamber 14 drops and a piston 10 is pushed up, overriding the first spring 19 by the help of pressure in the primary chamber 13. Then, the valve body 11 moves away from a valve seat 18, and a flow takes place. The first magnet 17 generates the higher resiliency, when the coil 25 is supplied with the more current, thereby bringing the valve body 11 near the valve seat 18 and throttling a flowrate. According to the aforesaid construction, simple constitution can be applied.
