IPC: G11B23/033
Filed: 1986-06-17
Abstract: PURPOSE:To make space efficiency effective, and to make the titled disk cassette small and thin in size by providing a means for pressing a magnetic disk against a recording and reproducing head, on the cassette. CONSTITUTION:When a cassette holder 1 is moved in the direction A, a spindle 10, and also, a magnetic head 9 and a carriage 7 are inserted into the holder 1 from a bottom face opening part 1A of the holder 1, and a bottom face groove-shaped opening part of the holder 1 in the same way, respectively. When the holder 1 descends to a fixed position, the spindle 10 pushes up a magnetic disk 5 in the direction B, and a pad 2 is inserted into the inside of a cassette from an opening part 4A of the cassette 4 and pressed against the disk 5. By providing the pad in such a way, an oscillating mechanism is omitted from the pad side, and the head is pressed by an elastic force of the pad itself and an elastic force of a damper for supporting the magnetic head, therefore, the head can be pressed more stably. Also, a space required for operating of the mechanism can be reduced.

Title: Motor driver
Inventor: TANAKA TATEAKI
IPC: H02P6/21
Filed: 1994-05-31
Abstract: PURPOSE:To suitably drive a sensorless brushless motor by coping with noise in a signal at the time of driving the motor. CONSTITUTION:A motor 11 has armature coils (u), (v), (w), a neutral point (n) and a rotor 11r. The voltage of a battery 20 is applied to the coils via a switching unit 21. A low-pass filter 30 is connected to the point (n) corresponding to armature currents to removes noise from a signal. At the time of starting, the rotating position of a rotor is detected from the voltage of the point (n). When the armature currents are large, filter means is selected, while when they are small, a neutral point voltage signal is selected. The armature excitation is switched according to a predetermined exciting pattern. It is transferred to a predetermined normal time drive operation based on a revolving magnetic field detection signal. Noise is removed by second filter means which can pass a signal of a higher frequency range than that of first fitter means. Thus, the drive control in which the influence of the noise is small can be executed even at the time of the normal operation.

Filed: 1996-05-09
Abstract: PROBLEM TO BE SOLVED: To provide a new format DRAM (dynamic RAM) capable of coexisting with a conventional DRAM and high speed operation by clock control after the coexistence is ended. SOLUTION: A circuit generating an intra-bank XRAS becoming active for a prescribed period from a row address strode (XRAS) inputted from the outside by intra-bank controllers 111-114 of the DRAM having a plurality of banks A-D is provided. Memory access in its bank is performed independently of the external row address strobe by output enable (XOE), column address strobe (XCAS), etc., occurring between occurrence and stoppage of internal XRAS. Thus, pipe line control is made possible while making the coexistence with the conventional DRAM possible. At the point of time when the coexistence with the conventional DRAM is ended, the XCAS is used as a clock, and the DRAM is accelerated.

IPC: G06F17/14
Filed: 1988-06-06
Abstract: PURPOSE:To quickly transpose an arbitrary number of bits by preliminarily storing the number of bits to be transposed in a register. CONSTITUTION:When 16 information inputted from a bus 19 in series have bits transposed and are stored in a memory 10, address transposition of 4 bits is necessary and '4' is stored in a register 15. Contents '00000' of a register 17 are sent to a gate 16 and a 5-bit transposing circuit 12. The gate 16 sets only lower four bits to '0000' by the indication of the register 15. The transposing circuit 12 sets a pointer 11 to '00000'. A barrel shifter 13 shifts bits right by one bit obtained by subtracting the number of bits in the register 15 and sets the upper bit to '0' to set '00000'. OR between outputs of the gate 16 and the shifter 13 obtained by an OR circuit 14 is given to the pointer 11. First information is stored in the memory 10 in accordance with contents of the pointer, and an incrementer 18 sets contents of the register 17 to '00001'. Since the barrel shifter and the OR circuit are added, the number of bits from the least significant bit of the pointer are quickly transposed.

Abstract: PURPOSE: To protect the surface around a port against damage due to heating and to protect a burner against damage due to backfire by making one or more specified port at a multiport burner smaller in area than the remaining ports and providing means for detecting the presence of a flame within a specified port. CONSTITUTION: Outlet wall 1 of a burner is made of a slotted plate of ceramic, or the like wherein each slot 2 forms outlet of fuel and air having identical bore area.

A thermocouple probe 5 extends into the port 2' through the restrictor 4 and the forward end 6 of the probe 5 terminates at a distance about 6 times as long as the bore diameter of the restrictor from the upstream end 3. At the time of normal combustion, no signal is delivered from the probe 5 and a valve 8 is opened by a control box 7.  When the ratio of air in a fuel/air mixture decreases and the combustion face begins to be heated, retraction of flame (light back) takes place in the port 2' and the probe 5 is heated by the flame in the port 2' to provide the control box 7 with a signal for closing the fuel valve 8 thus protecting the burner.

IPC: H01S3/038
Filed: 1985-06-28
Abstract: PURPOSE:To cause uniform and high power density discharge to occur as well as to lower the firing potential by making the distance between the surface of a cathode divisional electrode of the gas upstream side and the anode shorter than the distance between the surface of the gas downstream side and the anode, thereby suppressing the negative glow on the cathode surface.

That is, it is sufficient that the distance ld of the gas downstream side is longer than the distance lu of the upstream side. With this, at the discharge start-up time, discharge occurs at the upstream side, the negative glow extends to the downstream as the discharge power is gradually increased, and in addition, the negative glow stably exists on the whole split electrode, whereby the discharge region widens and is stable and uniform discharge is obtained. Further, the maximum voltage of the power source can be reduced, enabling the device to be small and less expensive.
