Title: Copying device
Inventor: OGINO SHIGEO
IPC: G03G15/00
Filed: 1988-01-16
Abstract: PURPOSE:To prevent a copying sheet without a formed image from being distributed to a sorter by accommodating the latter half of the cut copying sheet in a place other than sorting bins used when the cut copying sheet with a formed image is distributed by the sorter. CONSTITUTION:When the copying sheets of a prescribed size are exhausted, a copying sheet having an area twice said sheet is fed and bisected; copying operation continues. The latter half of the cut copying sheet without a formed image is accommodated in the place other than the sorting bins used in a sorting mode. Thus, the copying sheet without a formed image is not distributed by sorter 50 with a copying sheet having a formed image.

Abstract: PURPOSE:To enable the installation and removal of a device and the maintenance effected by arranging a limited slip differential device at the outside of a differential gear support bearing on a differential sidegear shaft and between a differential final gear and a differential sidegear shaft. CONSTITUTION:In a transmission case M which is composed of a right case 1 and a left case 2, the left case 2 is allowed to be a rear axle housing simultaneously so as to enable a limited slip differential device A to be contained inside, and the right case 1 is allowed to contain a differential gear device D at its center.

Title: Packing in cylinder-piston equipment and setting device thereof
Inventor: HASEGAWA KISAKU
IPC: F16J15/24
Filed: 1988-01-16
Abstract: PURPOSE:To make packing change so easily and its service life longer by overlapping plural pieces of packing with respective cutting spots in the radial direction with one another in the axial direction of a piston, and furthermore installing these cutting spots of each packing in shifting their positions to one another. CONSTITUTION:A sealing structure for sealing a hydraulic fluid 16 is provided with plural pieces of packing 8a-8c between a packing holder 9, having a taper part in an inner circumferential part, and a cylinder 3. Respective cutting spots at those of packing 8a-8c are set up in shifting their positions to one another.

Consequently, since uniform contact pressure is imposed to a sliding part between the packing 8a-8c and the cylinder 3, packing life becomes prolonged. In addition, operation of the cylinder 3 at slow speed is very smooth. Moreover, an interchange of the packing 8a-8c is easy enough.

Title: Dynamic type semiconductor memory device
Inventor: DOSAKA KATSUMI
IPC: G11C11/4094
Filed: 1988-01-14
Abstract: PURPOSE:To eliminate the delay of an access in a normal cycle and to reduce a current at the time of an action and a current necessary for holding a storage by equalizing the potential of a bit line pair in an off-time period, simultaneously, supplying an intermediate potential, stopping the supply and executing the access. CONSTITUTION:In the normal mode, since a bit line pair BL and BL is equalized in a standby period and a precharge potential VBL is given to the bit line pair BL and BL, the potential of the bit line pair BL and BL is held at 1/2.Vcc. Consequently, when an active period is in, the equalization and the supply of the precharge potential VBL are immediately stopped in a selected block, and a word line driving signal phiWL can be made to rise. Thus, the access can be executed at a high speed. On the other hand, in a refresh mode, since the equalization and the supply of the precharge potential VBL are not executed, and a precharge potential generating circuit 5 is not operated in being interrupted from a power source, an energy consumption can be saved.

Title: Formation of insulation layer
Inventor: KITAJIMA HIROSHI
IPC: H01L21/314
Filed: 1984-01-19
Abstract: PURPOSE:To obtain the insulation layer exerting no effect on Si even through high-temperature processes by a method wherein three layers or more of CVD Si3N4 films produced in the same manner as an SiO2 film are provided by lamination in forming an insulation layer used for element isolation, interlayer insulation, and passivation.

Patent JP-H11201793-A (JP)
Title: Flow rate sensor
Inventor: YAMAKAWA TOMOYA
IPC: G01F1/68
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To improve the sensitivity to the forward flow by setting the heating current of an upstream heat-sensitive resistor to be larger than the heating current of a downstream heat-sensitive resistor when the flow rate is zero to simplify the positively and monotonously increasing output from the detection of the reverse flow to the detection of the forward flow. SOLUTION: When the heating temperature of upstream and downstream heat- generating resistors 4, 5 is changed, based on the measured temperature of the fluid detected by measured fluid temperature compensation resistors 6a, 6b, the heating current value becomes the function of the quantity corresponding to the product of the flow speed of the fluid to be measured and the density. When the flow speed of the fluid is increased, the heat transfer from the upstream heat generating resistor 4 to the fluid is increased, and the heating current is increased. The heating current is less increased in comparison with the heat generating resistor 4 because the gas flow heated by the heat generating resistor 4 flows in the downstream heat generating resistor 5.  The flow rate and the flow direction can be detected by obtaining the difference in the heating current between the upstream and downstream heat generating resistors 4, 5, and the difference VM1-VM2 in voltage drop at reference resistors 24a, 24b by a differential amplifier 34.

Title: Drive circuit of light-emitting element
Inventor: OGASAWARA KAN
IPC: H01L23/58
Filed: 1994-01-28
Abstract: PURPOSE:To prevent the influence of an abnormal current generated by an external cause by providing a current limiting means which limits the abnormal rush current supplied to a light-emitting element. CONSTITUTION:A laser voltage regulator 52 generates a stabilized voltage supplied to a semiconductor laser 41 from a nonstable power supply voltage V1 and regulates the voltage and an overcurrent limiter 53 limits an abnormal rush current to the laser 41. The abnormal rush current includes the rush currents generated when the power supply is turned on, when a constant-current circuit 51 becomes defective, or a CPU makes an APC control error. The current value at which the limiter circuit 53 starts operations is set higher than a prescribed current value set to the circuit 1 and lower than the maximum allowable current value of the laser 41. Differently from the case where APC control is made by indirectly discriminating abnormality caused by an APC error from the information given by returned signals from a photodiode near the semiconductor of the laser 41, the abnormal state can be limited timely with no time lag.

Title: Electric power supply controlling circuit
Inventor: HAYASHI KENJI
IPC: G08B29/18
Filed: 1981-01-22
Abstract: PURPOSE:To prevent generation of an alarm error, by disconnecting a supply voltage of the side to be controlled, in case when the supply voltage of the controlling side is dropped or disconnected. CONSTITUTION:In the normal state, negative voltage being an electric power source to be controlled is applied to an input terminal 15, and +5V is applied to a control terminal 11. In this case, the base bias is applied to a transistor 14 by resistors 12 and 13, and it is turned on. When the transistor 14 is turned on, a current flows to resistors 16 and 17, and it becomes base bias of a transistor 18. As a result, the transistor 18 is turned on, and outputs a voltage of the electric power source to be controlled, from an output terminal 19. By this output, an alarming circuit is driven. Subsequently, when an input voltage of the control terminal 11 is dropped or disconnected, the transistor 14 is cut off, by which the transistor 18 is also cut off, therefore, no output is outputted from the output terminal 19.
