IPC: G06F5/06
Filed: 1990-04-13
Abstract: PURPOSE:To reduce a phase difference between write and readout by devising the memory capacity to be freely set externally. CONSTITUTION:When a desired storage capacity is entered to an address control circuit 12 by using a storage capacity signal MS, the circuit 12 monitors a write pointer circuit 2 and a read pointer circuit 3, compares an address corresponding to a setting storage capacity with write and read addresses generated respectively from the circuits 2, 3 and controls the write pointer circuit 2 and the read pointer circuit 3, by which a required storage capacity is set. As a result of setting an adaptive storage capacity, the phase difference between the write and readout is decreased in the FIFO memory.

Title: Cooling and heating device using metal hydride
Inventor: MOROZU MASAKAZU
IPC: F25B17/12
Filed: 1989-04-18
Abstract: PURPOSE:To minimize sensible heat in each vessel during change over operation and improve system efficiency by positioning a cooling and heating block on a higher temperature side in a lower elevation than a lower temperature side block when changing over two sets of cooling and heating blocks alternately, transferring heat from a higher temperature side vessel to a lower temperature side vessel by the opera tion of a gravity type heat pipe, and hence eliminating differential temperature between both the vessels. CONSTITUTION:A vessel 1 is filled with metal hydride M1H at a temperature of TM. A vessel 3 is filled with metal hydride M2H at a temperature of TL. A vessel 2 is filled with M2H and lags by a semi cycle compared with the vessels 1 and 3 and the temperature is TH. A vessel 4 is filled with M2H at a temperature of TW and hydrogen is assumed to have finished its transfer motion to the vessels 1 and 4. If a frame 10 is tilted when cooling load is taken out from the lower temperature side vessel 4, heat will be transferred from the vessel 2 to the vessel 1 by the action of a gravity type heat pipe 9 and both vessels will be turned at a temperature of (THTM)/2 in a fixed time. With regards to the vessels 3 and 4, the temperature in the vessel 3 varies from TL to (TM+TL)/w while the temperature in vessel 3 varies from TL to (TM+TL)/2 while the temperature in the vessel 4 varies from TM to (TM+TL)/2.

IPC: H01L21/68
Filed: 1999-04-06
Abstract: PROBLEM TO BE SOLVED: To form a surface which resists donor effect of impurities wherein oxygen, carbon, etc., are dissolved by controlling surface conductivity, by introducing a material which reduces donor effect into a supporter surface of a board supporter. SOLUTION: A ceramic body with a supporting surface comprising a material which reduces donor effect has a first part 102 and a second part 112 arranged on the first part 102. Alkaline metallic oxide which reduces donor effect is mixed inside the second part 112. Alkaline metallic oxide which is a material to reduce donor effect is beryllium, magnesium, calcium, strontium, etc., and it reacts with oxygen or carbon existing during use of a chuck 100 and forms a mixture which is stable and does not give electron in the chuck 100. Donor effect of electron is thereby reduced, thus preventing chucking force from disappearing permanently.

Title: Perpendicular magnetic recording method
Inventor: KAWABATA TOMOYUKI
IPC: G11B5/09
Filed: 1988-04-21
Abstract: PURPOSE:To suppress recording demagnetization to a minimum by delaying the rising of a recording current only for a time, which is needed for a medium to move the gap length of a ring-shaped head, when the recording current is switched. CONSTITUTION:Transistors TR1 and TR2 are respectively turned on and off by Q-output and Q-output of a T-FF2 and respective emitters are grounded through the collector and emitter of a transistor TR3 with being commonly connected. This transistor TR3 is turned on and off by an output Qe of an exclusive NOR gate 3 and the base of the transistor is pulled-up by a resistor R and connected to the output edge of the NOR gate 3. This NOR gate 3 obtains exclusive OR between the Q-output of the T-FF2 and an output Qd of a delay circuit 4 and outputs an inverting signal as a signal Qe. The circuit 4 outputs a signal Qd, for which the Q-output of the T-FF2 is delayed only by a delay time (td). This time (td) is set based on a delay time setting signal S from a controller which controls the respective parts of a hard disk device.

Title: Method for testing logical circuit
Inventor: OGAWA KOUJI
IPC: G01R31/28
Filed: 1984-05-18
Abstract: PURPOSE:To make it possible to allow the output signal of a multivibrator to be synchronous to the strobe signal of a tester, by temporarily short-circuiting both terminals of the externally mounted condenser of the multivibrator and making an output pulse width indefinite apparently. CONSTITUTION:Both terminals of the externally mounted condenser 2 of a multivibrator 1 are temporarily short-circuited by a strap wire 3 and, because no charge is applied to the externally mounted condenser 2 of the multivibrator 1 triggered at the rising of B-input, Q-output succeedingly holds a high level regardless of inherent time series. Further, it is possible to bring the Q-output to a low level by making clear input low. In addition, because the B-input and the clear input are generally synchronous to the strobe signal of a tester, the Q-output of the multivibrator 1 can be made synchronous to the strobe signal of the tester.

Title: Light collector and productuon thereof
Inventor: GREUBEL WALDEMAR
IPC: F21K2/00
Filed: 1979-08-02
Abstract: A light-collecting device in the form of, for example, a rectangularly-shaped body having a so-called "fluorescent plate" with at least one light-exit window is comprised of a solid polymerized synthetic carrier material, such as a polyacrylate, a polymethacrylate, a polystyrene or copolymers thereof, containing fluorescing particles therein which have finite dipole moments with different values in the basic and in the excited state and containing a polar organic additive, such as a high-boiling polar solvent, for example, an aliphatic or aromatic alcohol, a nitrile or an ionogenic or non-ionogenic soap, with the fluorescing particles and additive being substantially uniformly distributed throughout such carrier material. The additive creates an environment with an orientating polarization about the fluorescent particles whereby the environment can re-orientate so-quickly that it achieves its thermodynamic equilibrium substantially completely during the existence of the excited state in the fluorescing particles and tends to suppress the disruptive self-absorption of light within the fluorescent plate. Such self-absorption originates from a partial overlap of the emission spectrum with the absorption spectrum of the fluorescing particles. The additive can be dissolved in the synthetic carrier material or can be chemically linked therewith and the so-attained system can be injection moulded, extruded or cast into a desired body form. The disclosed device is useful as a solar collector, an optical indicia transmitter or an image brightener for passive displays.
