Title: High speed diode
Inventor: SAKURAI KEIJI
IPC: H01L29/861
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To provide a low-noise high-speed diode wherein, with no increase in switching loss, etc., high frequency driving is possible, by providing, between the third and second semiconductor regions, the fourth semiconductor region whose impurity concentration is lower than the third semiconductor region. SOLUTION: With an epitaxial wafer wherein the second semiconductor region (n epitaxial layer) 2 of high resistance is grown on an n<+> substrate 1 containing high-concentration arsenic, the third semiconductor (first p<+> anode) region 4 and the fourth semiconductor (second p anode) region 5 are, on its surface layer, selectively, in a duplex manner, formed by implantation of boron ion and diffusion thereafter. The first p<+> anode region 4 is high in surface impurity concentration while shallow in diffusion depth, however, the second p anode region is low in surface impurity concentration while deep in diffusion depth.  Since the impurity concentration of the second p anode region 5 is low, the number of positive holes implanted from the second p anode region 5 to an i layer 9 in forward bias condition decreases, so, a reverse current in transient phenomenon when switched to a reverse bias state is small, while the reverse restore time is short, for a high-frequency operation.

Abstract: PURPOSE:To prevent each track from having a difference in output voltage due to variation in source voltage by providing (m+n) units of light emitting elements, 2(m+n) units of photodetecting elements, and (m+n) units of comparators, supplying the source voltage to (m) units of light emitting elements connected in series, to (n) units of light emitting element connected in series through diodes, and to the connection point of two photodetecting elements as a reference potential, and supplying its divided voltage as an offset voltage. CONSTITUTION:Diodes D1 and D2 are provided between a bias resistance RZ and a light emitting diode LZ to provide a half forward voltage drop across each light emitting diode, and RZ1, RZ2, RB1, RB2, RA1, and RA2 are resistances for giving an offset. The total forward voltage drop across the diodes D1 and D2 and light emitting diode LZ is equalized to the total forward voltage drop across the light emitting diodes LB and LA, and consequently even if the source voltage VCC varies, the variation rate of the quantity of light of the light emitting diodes LZ-LA is unchanged, thus preventing the output from varying with the quantity of light incident to an uncorresponding photodiode.

Title: Oil-hydraulic clutch type speed-changing device
Inventor: TSUDA TOSHIO
IPC: F16H61/30
Filed: 1980-01-19
Abstract: PURPOSE: To obtain optimum feeling of start for each group of speeds by providing two or more pressure control valves and making them operate corresponding to the selection of each group of speeds.  
     CONSTITUTION: A pressure oil port 17 is connected with the pressure oil port of the directional control valve of an oil-hydraulic clutch and with the oil-pressure port 18 of a pressure control valve A. When the directional control valve is shifted from neutral to the 1st speed or the 2nd speed or the like, the pressure oil is supplied to the cylinder of the oil-hydraulic clutch through the intermediary of the directional control valve. And, although oil pressure rise is going to rise to a set level for a moment to engage a friction plate, a spool 12 movable by a pressure of about 1W2kg/m 2  moves to the right by the pressure of the pressure oil from the port 18 and the pressure oil from the port 18 is drained to the port 23 of a relief valve. However, since the pressure oil gets in gradually from a port 19 through a throttle orifice 22 and pushes a spool 13 to the left, the spool 12 moves to the left by the push of springs 14 and 15 and thereby pressure rises gradually.

Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To reduce load of a host by preventing degradation of image due to insufficient bus width and memory and supporting logical operation between images. SOLUTION: Upon receipt of printing data from a host, image data is generated per band by an image drawing/compression/expansion part 804 and specified operation is conducted per band between images and image after operation is compressed and stored. When images for one page have been stored, the images are expanded, printed and outputted from a printer engine 806. Generation of image and logical operation is conducted per band, and hence required memory capacity can be reduced and the image is compressed after being processed so that memory for storing image can be reduced. As a result, sufficient memory capacity is provided, and hence resolution and gradation are prevented from being omitted.
