Title: Semiconductor memory device
Inventor: OSAWA TAKASHI
IPC: H01L27/108
Filed: 1985-12-28
Abstract: PURPOSE:To execute a data transmission at high speed by providing a means to latch statically the signal on a bit line onto an I/O line and means to precharge the electric potential of the I/O line to the intermediate electric potential before latching. CONSTITUTION:To an I/O and the inverse of I/O line pair, the signal, which can be detected by an I/O buffer circuit 75, is sent from bit lines BL and the inverse of BL, and then, independently, the signal is latched. Thus, it is not necessary to obtain the spare allowance, and rapidly, the data can be transferred to a read data line RD. At the circuit, the electric potential of the I/O and the inverse of I/O lines is precharged to an intermediate electric potential VM of a power source electric potential and an earth electric potential by a precharging circuit 55. Thus, then a signal line CSL is led, the I/O and the inverse of I/O lines connected to the higher electric potential out of the bit liens BL and the inverse of BL are ascended to the power source electric potential from the electric potential VM without fail. Since the I/O line and the inverse of I/O line connected to the lower electric potential are descended from the electric potential VM, the time is hastened in which the necessary level difference is made.

Filed: 1987-11-27
Abstract: PURPOSE:To contrive prevention of generation of smokes and odors at the time of welding, by setting the thickness of the inner one of skin steel plates to be at least 1.5 times that of the outer skin steel plate. CONSTITUTION:The thickness of an inner skin steel plate 2 is set to be at least 1.5 times that of an outer skin steel plate 1, in a weldable composite-type vibration-proof steel plate 5 having a resin layer 4, comprising a conductive filler 3 as a core material, between the outer skin steel plate 1 and the inner skin steel plate 2. When two such composite-type vibration-proof steel plates 5 are welded to each other, with the inner skin steel plates 2 jointed to each other, by a pair of electrodes 6, a nugget having a sufficient joint strength is obtained. Since the resin layers 4 are located on the side of the electrodes 6, the resin layers 4 are remote from the nugget-forming position, and combustion of the resin layers 4 is restrained, so that the quantities of smokes and odors generated are markedly reduced.

The material m (i, j) and the concentration C (i, j) at the time of the end of a first process obtained in such a way are transferred to a second process. Thereby, the number of retention data at the time of the transfer from the first process to the second process is few and a high-accuracy simulation can be performed.

IPC: A61B3/12
Filed: 1999-10-20
Abstract: PROBLEM TO BE SOLVED: To enhance the accuracy of measuring vascular diameters and to apply stable tracking by accurately detecting a specific point during the calculation of a vascular diameter. SOLUTION: A quantity of deviation is input to an illuminating light quantity control means 50 from a vascular position computing means 76 and, when the quantity of deviation is smaller than an allowable value, the control means 50 determines that tracking is applied, and outputs a reflected light distribution sensing start signal to a reflected light distribution sensing means 48. The reflected light distribution sensing means 48 senses an output difference (reflected light distribution) between before and after the peak of a waveform, and outputs the result to the illuminating light quantity control means 50, which in turn compares the result to a set value.  When the result is equal to or greater than the set value, a signal is output to an illuminating light distribution changing means 51 so that the distribution of quantities of light of a rectangular tracking indicator T irradiated to the fundus oculi Ea varies.

Abstract: PURPOSE:To raise the speed of even processings other than operation by switching the integration time of image sensors and a signal transfer clock in a focus detector which uses selectively one-bit or two-bit digital signals to operate an extent of defocus. CONSTITUTION:An object image is formed on image sensors I1 and I2 through a lens, and electric charge storage information is transferred by a CCD 12 and is processed in a microcomputer 8 through an INF 10, and the extent of deviation between images and the focusing state are decided in accordance with correlations between image signals.

An A/D converting circuit for one bit and that for 8 bits are provided in the INF 10, and required storage electric charge is monitored by a monitor element near the CCD light receiving part to select A/D converting circuits. When the A/D converting circuit for one bit is selected, the microcomputer 8 shortens the electric charge storage time and raises the transfer clock frequency of the CCD to improve the speed of the arithmetic processing though the accuracy of distance measuring is degraded somewhat.

IPC: H04N1/00
Filed: 1992-10-12
Abstract: PURPOSE:To easily set a mode with a small number of switches by providing a mode selecting means which sets the operation mode of a device to the reception mode or the polling mode. CONSTITUTION:An operator indication detecting means 20 detects operator's indication of manual polling processing, and a transmission document presence/ absence detecting means 21 detects the presence or the absence of a transmission document, and a signal detecting means 22 checks whether a signal DIS or a signal CNG is detected from a line, and a timer means 23 is started based on the output from the operator indication detecting means 20 and measures the time. A mode selecting means 24 selects the polling mode or the reception mode based on outputs of the operator indication detecting means 20, the transmission document presence/absence detecting means 21, the signal detecting means 22, and the timer means 23. Since the facsimile equipment automatically determines the operation mode, it is unnecessary for the operator to recognize the operation mode, and the number of switches is reduced.

Title: High-voltage power unit
Inventor: ENDO SATOSHI
IPC: H02M3/28
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To provide a high-voltage power unit which can make a load usable, until its service life expires by minimizing the damage given to the load, even when the impedance of the load changes. SOLUTION: In a state where the output voltage H.V of a high-voltage power unit is stable, a current detecting means 2 detects the current of a transistor Tr2 and calculates the impedance of a load Z, based on the detected current value. When the calculated impedance of the load Z is smaller than a prescribed value, the power unit reduces the current of the load by dropping its output voltage. When the detected current value is smaller than the prescribed value, the unit increases the detecting accuracy of the current by switching a current detecting resistor R1 to another current detecting resistor R2 which has a higher resistance value than the resistor R1 has.

Filed: 1985-12-30
Abstract: PURPOSE:To omit a recess by constituting a push broach, which forms a groove for a spline on a blind hole by insertion/return cutting, with cutting edges formed with edges in the forward direction, a middle guide section, and a return edge formed with an edge in the backward direction. CONSTITUTION:A cutting edge section 5 is constituted of cutting edges 6, a return edge 7 and a middle guide section 8. The cutting edges 6 are formed with the first, second and third cutting edges so that the outer shape is made gradually larger from a forward guide section 3 toward a shank 2. Edges 6a of these cutting edges 6 are formed in the direction of the forward guide section 3, and the edge 7a of the return edge 7 is formed in the direction of the shank 2. Accordingly, the prepared hole 10 of a work 9 is cut into a predetermined shape by the cutting edges 6 at a push and is cut by the return edge 7 at a return process, thus no burr is generated in the prepared hole 10 of the work 9, and no recess is required to be formed. In addition, high accuracy can be obtained.
