Title: Delay optimization method
Inventor: NAKAMURA ATSUSUKE
IPC: G06F17/50
Filed: 1995-06-26
Abstract: PURPOSE: To reduce calculation processing time and to reduce the increase in the LSI layout pattern area of a sequence synchronization circuit without affecting the maximum delay time by inserting a level latch into a signal path which violates the minimum restriction delay and giving an apparent delay. CONSTITUTION: A minimum delay is compensated and a delay time is added at a delay optimization part 6 for a signal path where the delay time is in shortage while violating the minimum delay restriction which is inputted and newly determined by a restriction condition input part 3 in a sequence synchronization circuit inputted from a circuit input part 2.  At the delay optimization part 6, the degree of overlapping of the signal path which violates the minimum delay restriction for each output terminal included in the sequence synchronization circuit is calculated and a label latch is inserted so that the area of the LSI layout pattern of the sequence synchronization circuit can be minimized in the order of a signal path where the degree of overlapping is large, thus reducing calculation processing time without affecting the maximum delay time and reducing the increase in the LSI layout pattern area of the sequence synchronization circuit.

IPC: G11B21/08
Filed: 1991-06-04
Abstract: PURPOSE:To make the seek operation of a head accurate by synchronously operating a speed control for every specified cycle waiting until next speed detection. CONSTITUTION:An optical disk 1 is rotated at a constant speed by driving a driving system on an information recording medium. An optical system 2 is provided with a sensor for optically recording information on the disk 1, reproducing the recorded information of the disk 1 and detecting a reflected light. A condensing objective lens provided in the optical system 2 is moved in the direction of a focus by a focus actuator 13 and the objective lens is moved in the direction of a tracking by a tracking actuator 12. Here, an error signal is detected and control the speed of the disk 1 by the focus or tracking difference detectors 3 and 4 based on the output of the sensor. At this time, the speed control for every specified cycle is waited until the next speed detection and the speed control is synchronized with the speed detection. Thus, the follow up ability of the information recording or the regenerating head to a target head is improved and the seek operation of the head is accurately controlled.

Title: Through hole inspector
Inventor: MITA KIKUO
IPC: G01R31/02
Filed: 1985-07-19
Abstract: PURPOSE:To achieve a higher speed of inspection, by deflecting light from a light source emitting light constantly with a rotary polyhedron to irradiate an area to be inspected instantaneously. CONSTITUTION:Light from a light source 51 constantly emitting light is deflected with a rotary polyhedron 52 and transmitted through a lens 54 to be inputted into a plurality of optical fibers 53. Then, the light propagated through the optical fibers 53 irradiate an area to be inspected from the back of an light intercepting object 2 passing through respective lenses 55. Here, as at least the light intercepting object 2 is arranged between the lens 55 and a printed wiring board 1 to intercept light from a through-hole 12, the light entering a light-transmitting substrate 13 from any part other than the light-intercepting object 2 leaks into the through-hole 12 from a defect 14 in a conductive layer 11, if any, to make the through-hole 12 bright inside owing to the leakage. The light is taken with a TV camera operating in synchronization with the rotary polyhedron 52 via a lens 41 and the presence of the defect is judged with a defect judging circuit 7. This permits a higher speed of inspection of a through-hole while elevating the inspection reliability.

Title: Measuring method for powder and granule
Inventor: HAYASHI YUTAKA
IPC: G01G13/24
Filed: 1981-10-09
Abstract: PURPOSE:To measure the weights of powder and granule with high accuracy over the entire area by disposing a pair of load cells one of which is large in capacity and the other is small in capacity in the state of supporting a weighing beam at the point of working or of force provided with a weighing hopper. CONSTITUTION:When powder and granule are charged into a weighing hopper 29, the load against the energizing force of a coil spring 28 acts upon a weighing beam 21, and the load upon a load cell 26 of large capacity is decreased. Then an arithmetic display device 31 converts the decreased value of load upon the cell 26 to a load values and dsplays the same. When the weight of the power and granule exceeds the energizing force of the spring 28, the beam 21 abuts to a load cell 27 of small capacity, and the load is exerted upon the cell 27. Thus the measurement threshold region where the accuracy of measurement is unstable, that is, the final delicate weight of the intended weight is measured with the cell 27 of small capacity, whereby the accuracy of measurement is markely improved.

Filed: 1989-06-22
Abstract: PURPOSE:To enable absorption and removal of each kind of radioactive nuclide with using rather small amount of an adsorption agent by treating a low level radioactive waste liquid with using a naturally produced glauconite. CONSTITUTION:Glauconite is a mutli-elements mineral consisting of special metamorphic rocks which are an aggregation of a chlorite, an amohibole, an apatite and the like. A radioactive liquid waste is treated by a flowing-through process that the glauconite particles of around 0.1 to 5mm in diameter are filled in a column and the radioactive waste liquid is fed from an end of the column, or by a batch process that the glauconite particles or powder are added to the radioactive waste liquid and are agitated altogether. Though an amount of the glauconite to be used as an adsorption agent differs accordingly to kinds and concentrations of radioactive nuclides contained in the radioactive waste liquid a range of the amount is usually within 0.5 to 5 weight parts against 100 weight parts of the radioactive liquid waste. After the treatment, the glauconite is separated from the waste liquid and is dried up as it is, or is solidified by a cement or a plastic.

Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To supply electric power to a load securely without using an extension cable, etc., by a method in which a detecting means which detects whether a switch between an inverter and a commercial AC power system is opened or not is provided, and the inverter is put into the self-operated operation only when the detecting means detects that the switch is opened. SOLUTION: If a service interruption detector detects the interruption of a commercial AC power system 5 in accordance with the output of an inverter 2, a current flowing between the commercial AC power system 5 and this system, etc., the service interruption detector stops the inverter 2. After the detection of the interruption, an open/close detector 31 detects whether a switch 3 is opened or not, and the detection output is supplied to a control means 21 which puts the inverter 2 into a self-operated operation mode. With this constitution, as a plug-socket exclusively for the self-operated operation is not used, electric power can be securely supplied to a load without using an extension cable, etc.
