Title: Control system for transfer of data
Inventor: SHIRAKU YUTAKA
IPC: G06K15/00
Filed: 1986-09-03
Abstract: PURPOSE:To transfer data at a high speed with a small number of circuits by providing plural FiFo to a picture data output part of a printer device to write the next picture data to one of both FiFo when the picture data are read out of the other FiFo. CONSTITUTION:A memory circuit 1 of a non-impact printer stores a single dot of the output picture data in response to a single dot of a memory. When a single dot line output request signal B and a single byte output request signal C of a 1st dot line are inputted to a control part 4, a picture data request signal (b) is outputted from the part 4. At the same time, the data on a 2nd dot line are outputted every byte from the circuit 1 and stored in an FiFo 3. In this case, the data on the 1st dot line are also outputted from an FiFo 2. Thus data are read out of the FiFo 3 while data are written to the FiFo 2 and data are written to the FiFo 3 while data are read out of the FiFo 2.

Title: Noiseless discharge device
Inventor: TABATA NORIKAZU
IPC: H02M7/515
Filed: 1982-11-26
Abstract: PURPOSE:To permit an inverter to operate at higher frequencies, by prolonging the time of application of inverse voltage to the SCR of a power inverter, through maintaining the voltage between electrodes at a level smaller than the peak value. CONSTITUTION:An electric discharge device is started by a combination of a method in which the frequency is varied and a method in which the current is varied, in a manner explained below. Assume here that the frequency and voltage in the steady operating condition are f0 and Vp0. The current is gradually increased at a constant frequency lower than f0, and the voltage is raised to Vp0 while maintaining such a state that the reverse voltage time tr is greater than the time length toff for recovering the ability to check forward voltage even when the peak voltage Vp, which is equal to the discharge voltage Vb, is reached. Then, the frequency f is increased to f0 while maintaining the voltage Vp0 at a constant level, so that the steady operation of the discharge device is commenced. The change of the voltage Vp0 can be effected by varying the pressure in the gap. It is possible to use an inverter at higher frequency range, by attaining a matching between the discharging condition of the discharging electrode and the operating condition of the inverter.

Abstract: PURPOSE: To stand long storage and make usable at any time and in any place by arranging a thermoelectric power generating module utilizing Seebeck effect in the upper part of a light source such as a candle through a heat plate, and generating electric power by utilizing heat generated by lighting the light source. CONSTITUTION: Heat flow caused by heat from flame A of a candle strikes against a recess U of a heat control plate as shown in an arrow H, heats the heat control plate, passes through a vent hole h2 in the periphery of the heat control plate, takes in new air N from the outside, and flows in the upper part while it comes in contact with the outside of a cylinder 22 for heat radiation. The recess U of a heat control plate is efficiently heated, and the temperature of a second heat exchange substrate (high temperature side) 32 of a thermoelectric power generating module 30 is raised. On the other hand, a first heat exchange substrate (low temperature side) 31 of the thermoelectric power generating module 30 is efficiently cooled by new air flowing in contact with a cylinder 22 for heat radiating. The power generating module is sufficiently, practically used as a power source of a radio or an LCD TV in spite of generating electric power by using excess energy generating in association with illumination.

Abstract: PURPOSE:To efficiently obtain the compound useful as an intermediate, etc., for medicines, agricultural chemicals, etc., by adding an allyl alcohol and a peroxide to a solution of optically active diethyl tartrate, carrying out the asymmetric epoxidation, then esterifying the resultant product in the presence of an enzyme, separating the prepared ester and hydrolyzing the separated ester. CONSTITUTION:Optically active diethyl tartrate is preadded to methylene chloride and the resultant mixture is stirred and cooled. An allyl alcohol of formula I (R1 is 1-20C alkyl), together with t-butyl hydroperoxide, is then added to the obtained solution. The prepared mixture solution is stirred and titanium isopropoxide is added thereto to carry out the asymmetric epoxidation. Thereby, a crude optically active epoxy alcohol of formula II (* indicates asymmetric carbon) is obtained and then made to react with an acyl donor in the presence of a hydrolase in an organic solvent to preferentially esterify the (-)-isomer and provide an epoxy ester of formula III (R2 is the same kind as that of R1). The resultant epoxy ester is further separated from an optically active epoxy alcohol of formula IV. The prepared ester of formula III is then hydrolyzed to afford the objective optically active epoxy alcohol of formula V.

Title: Memory access controller
Inventor: KUWASHIRO YUTAKA
IPC: G06F13/28
Filed: 1989-08-10
Abstract: PURPOSE:To permit fast access to a memory device by supplying the value of an old address register provided to detect the change of a high-order address to which a CPU(arithmetic processor) makes access to a memory device before the CPU starts access after memory access, etc., in performing direct memory access (DMA transfer) is completed. CONSTITUTION:After the DMA transfer is completed, or after external refresh is completed, the high-order address to which the CPU 1 makes access before that is outputted to the memory device 2, and an address strobe signal corresponding to the address is outputted to the memory device 2 artificially. Therefore, when the CPU 1 starts the memory access, the memory device 2 already enters page mode access or static column mode access, which enables the access to be performed only by outputting a column address. In such a way, the quick access can be realized.

IPC: B23K9/10
Filed: 1982-11-29
Abstract: PURPOSE:To detect welding current irrespectively of whether it is AC or DC and to eliminate easily the influence of a high frequency component by disposing a magnetoelectric transducer within the magnetic field created by the welding current, and detecting indirectly the presence or absence of the welding current or the change thereof. CONSTITUTION:When welding current (i) flows in a cable conductor, an alternating magnetic field for detection is applied on a magnetoelectric transducer 20. The transducer 20 induces a Hall voltage (v) corresponding to the alternating magnetic flux and inputs the same to an amplifier 30. When the output Qv of the amplifier 30 is larger than a set current value K, comparators 50A, 50B output respectively signals P1, P2 having a constant level. A discontinuous signal P is outputted from an adder 60, and the signal P is converted by a continuous signal M by an integrator 70. Said signal is transmitted to a relay driving part 80 and therefore the relay operates and the flow of the prescribed welding current (i) is detected.
