Title: Optical sensor
Inventor: OKADA MICHITOSHI
IPC: G01B11/00
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To enable to control the output level of a light receiving means in the case of comprising a two-dimensional light receiving element. SOLUTION: A slit beam is emitted from a light projecting means 11 to a detection region, and its reflected light is received at a CCD 20, which is light receiving element. The CCD 20 is scanned along the direction of arrangement of light projecting and receiving elements, and the driving of the light projecting element 13 is controlled by a driving circuit at a sensitivity control means 25 so that the number of lines in which a peak value can be detected may become a predetermined number. Sensitivity control is performed by changing the width of pulses of projected light within a charge storage period or changing the level of projected light. By this, it is possible to perform the setting of optimal sensitivity.

Title: Information processor
Inventor: HIRONAKA MASA
IPC: G06F12/08
Filed: 1990-10-02
Abstract: PURPOSE:To prevent the memory cycle from being shortened even when a JMP instruction which follows an I/O instruction hits against cache memory by providing an input terminal for inputting hit/miss state information of the cache memory, a register which can be set by the I/O instruction, and a comparator for comparing the contents of this register and input information to the input terminal and information of a program counter of a CPU. CONSTITUTION:When an I/O instruction is inputted to a data bus 1, a CPU 11 inputs it to the inside, and stores it in a pre-fetch register 6. Subsequently, a JMP instruction is inputted, and stored in the register 6 in the same way. When the conditions that a value (in this case, a JMP instruction) set in advance to a register 5 and the JMP instruction in a program counter 7 is a JMP of the next instruction, and that what is inputted to an input terminal 2 is a cache hit are formed are satisfied, a comparator 8 extends the JMP instruction to the same cycle length as the time when a cache is not connected yet by a delay circuit 9.

Title: Sheet feed device and sheet processing device
Inventor: KAWAZOE KENJI
IPC: B65H3/56
Filed: 1995-10-12
Abstract: PROBLEM TO BE SOLVED: To feed a sheet by so small feed force that the extreme end of a sheet fed to the nip of a pair of carry rollers correcting oblique going of a sheet processing device (for example, a word processor) does not enter. SOLUTION: A feed roller 9 lets out a recording sheets S by the maximum radius (r1) part of the roller part 9a until it is separated from the slope of a slope wall 7d (a), and lets out the recording sheet S by the minimum radius (r2) part of the roller part 9a after it is separated from the slope of the slope wall 7d (b). By such operation, a plate spring 14 strongly presses the recording sheets S at a small angle α until the sheet separation is completed and the feeding force is large, but after completing sheet separation, the plate spring 14 weakly presses the recording sheets at a large angle β and hence the feeding force is reduced. Consequently, the extreme end of the recoding sheet S fed to the nip between a carry roller 18 and a pinch roller 19 for correcting oblique going does not enter.

Title: Soldering method of surface-mounting board and the soldering device
Inventor: NAKAMURA YUKIO
IPC: B23K1/00
Filed: 1988-10-20
Abstract: PURPOSE:To enable a board to be produced with improved yield by soldering while generating self-alignment by applying vibration to a member to be soldered while the soldering material is heated and fused. CONSTITUTION:A printed-circuit board 1 where a cream solder 3 is applied to and a flat package IC 4 is placed at a specified position is carried to a reflow furnace 6 by a belt 7 and is heated. Then, after preheating, the printed- circuit board 1 is heated at a temperature exceeding the melting point of the cream solder 3 and a vibrator 8 is operated when the printed-circuit board 1 is heated to a certain temperature, thus heating the printed-circuit board 1 while applying vibration to it in the direction of gravity. Thus, self-alignment can be generated even if the flat package IC 4 is large and soldering can be performed, thereby allowing the printed-circuit board to be produced with improved yield.

Title: Dc-dc converter
Inventor: OKADA YUKIO
IPC: H02M3/28
Filed: 1988-10-20
Abstract: PURPOSE:To lower output currents at the time of the protection of overcurrents, and to realize a DC-DC converter having foldback current limiting characteristics by fluctuating reference voltage input to an error amplifier in response to the pulse width of driving pulses applied to a switching element. CONSTITUTION:Since voltage proportional to driving pulses is applied to an error amplifier 9 together with reference voltage, a DC-DC converter works so that the DC level of an overcurrent detecting level (OCP level) is elevated when the pulse width of driving pulses is large and the OCP level is lowered when pulse width is small. When pulse width exceeds the OCP level when the pulse width of driving pulses is large in an overcurrent detecting element 6, the pulse width of driving pulses is reduced by a control circuit 7 in response to an error signal from the error amplifier 9 and output voltage V0 is lowered. Foldback current limiting characteristics in which output currents I0 are also diminished with the reduction of the OCP level can be realized.

Title: Semiconductor device
Inventor: NAKAJIMA HIDEHARU
IPC: H01L27/108
Filed: 1985-11-25
Abstract: PURPOSE:To increase the capacitance of a capacitor by forming a second semiconductor layer onto a first semiconductor layer through a second insulating layer and shaping the second capacitor. CONSTITUTION:A second semiconductor layer (such as a DOPOS film 7) connected to a diffusion layer (such as an n<+> layer 8) constituting a switching- transistor is formed onto a first semiconductor layer through a second insulating layer (such as an insulating film 5), and a second capacitor (such as a capacitor C2) is shaped by the first semiconductor layer, the second insulating layer and the second semiconductor layer. Accordingly, when cell size is made the same, the capacitance of a memory cell can be made larger than conventional memory cells by approximately twice, thus preventing the reduction of capacitance to occur with the fining of cell size.

Abstract: PURPOSE:To prevent occurrence of bending crack during construction of a PC beam by applying a reversely bending load to the PC beam with the use of a bundle which abuts against the lower surface of the center part of the PC beam by tightening up a wire rope. CONSTITUTION:A wire rope 8 incorporating a fastener 9 is stretched between a pair of fixtures 1, 1 which have been attached to the lower surface of a laid PC beam 10 at opposite ends thereof. Further, a bundle member 5 incorporating a lower pulley 6 is made to abut against the lower surface 10a of the middle part of the PC beam 10.
