Filed: 1987-04-30
Abstract: PURPOSE:To bend a plate material by one stage and to reduce the man-hour for the work by changing a bending span due to the movement of a bolster prepared in an equipment and a pressurizing position of an upper die in bending a plate material in a semi-ring shape. CONSTITUTION:A material 1 is positioned at a prescribed site on the bolster 2. Then, the bolster 2 is moved by the drive of a hydraulic cylinder, etc., simultaneously with bending work to reduce a bending span. At this time, pressure is applied from a press 7 through an upper die 3 and bending work is carried out gradually. In addition, in time of the final bending, that bending span is enlarged to be worked by application of the final pressure of the upper die 3 in a prescribed semi-ring shape. Furthermore, if the bolster 2 is moved up or down this structure can correspond even to H-dimension determined by various bending shapes.

Title: Semiconductor device
Inventor: ENDO TOSHIO
IPC: H01L21/30
Filed: 1988-04-27
Abstract: PURPOSE:To form an alignment mark, of a metal wiring layer, which is not stripped by an etching operation and to eliminate an initial failure and a failure after use for a long time by a method wherein the alignment mark, of the metal wiring layer, formed in a scribing region is arranged and formed on a semiconductor substrate via an insulating film. CONSTITUTION:A pattern 3 of an insulating layer film is formed under an alignment mark 2 for stepper use formed in a scribing region 1. Accordingly, when a metal wiring layer is etched, a part directly under the alignment mark 2 is not etched and scooped out in the insulating film that is hard to etch due to a semiconductor substrate 4. By this setup, the alignment mark 2 is not stripped off and is kept on the semiconductor substrate 4. In addition, since the pattern of the alignment mark of the metal wiring layer that has been stripped off does not adhere, an initial failure is reduced and the long-term reliability can be enhanced.

Title: Magnetic recording and reproducing device
Inventor: MIYAWAKI ISAO
IPC: G11B15/10
Filed: 1989-04-25
Abstract: PURPOSE:To eliminate unnecessary power consumption and to protect the subject device even when the device is equipped with a fan motor or the like by turning a power source off by detecting even such a case that the power source of the device main body is forgotten to be turned off by an internal timer circuit and automatically turning off the power source. CONSTITUTION:By pressing a power source button 2 under the off-state of the power source, this pressing is recognized by an input detecting circuit 4 and this information is sent to a power source control circuit 6, and the power source 8 is turned on by the circuit 6. By pressing the button 2 again, the information is transmitted through the similar system route, and the power source 8 is turned off. In this way, the on-off control of the power source 8 is carried out, and whenever the button 2 and other operation buttons are pressed, a timer circuit 10 is reset to return its count value to zero. If none of buttons are not pressed under the on-state of the power source 8, when a prescribed time is counted up by the timer 10, its information is outputted to the circuit 6, and hence the power source 8 is automatically turned off by the circuit 6. By this method, even when the device main body is left as it is for a long time operation, the unnecessary power consumption is never generated.

Title: Inventory control system
Inventor: IWASE TOMOKO
IPC: G06Q50/00
Filed: 1989-04-25
Abstract: PURPOSE:To attain the strict inventory control in terms of both the quantity and the amount of money by storing at least the inventory quantity and the reserve amount of money as the inventory data and performing the addition/subtraction of the reserve amount of money as well as the addition/subtraction of the inventory quantity when the commodities are stocked and taken out respectively. CONSTITUTION:When the slip data on the inventory of commodities are read out, the inventory record equal to the code of the corresponding stock commodity is re trieved out of an inventory file 7. Then the comparison is carried out between the unit price of the latest inventory (inventory 1) stored in a storage area 7a and the unit price of the inventory commodity. When no coincidence is obtained between both unit prices, the inventory data are shifted among plural storage areas 7a - 7e and the area 7a of the inventory 1 is defined as an idle one. Thus the inventory quan tity and the reserve amount of money of a slip are stored in the idle area 7a as the new inventory quantity and reserve amount of money of the latest inventory (inventory 1). When an out-of-stock slip is read out of a slip file 5, the inventory commodities are taken out of the inventory in the older inventory order. Thus strict inventory control is attained in terms of both the quantity and the amount of money.

Abstract: PURPOSE:To make the voltage stabilizing element for screen voltage unnecessary by applying the stabilized DC voltage to the ground side terminal of the variable resistor for adjusting the screen voltage. CONSTITUTION:Voltage of the point A of the fly-back transformer 1 is applied to one terminal of the variable resistor 2 for adjusting focus voltage, and to the ground side terminal of the aforesaid resistor 2 is connected one terminal of the variable resistor 5 for adjusting screen voltage through the dropper resistor 4. Also, the ground side terminal of the above resistor 5 is connected to the stabilized DC source through the dropper resistor 6. The aforesaid DC source rectifies with a diode 8 the pulses which come in the fly-back transformer, uses the circuit which smooths them with a condenser 9, and its voltage is approximately 190V. And if high tension current of the cathode-ray tube 3 is varied now, voltage of approx. 500V of the movable terminal of the resistor 5 is varied by approx. 50V, voltage of the above movable terminal becomes as 500-190VX0.1=31V owing to the stabilized DC source, which is less than 50V. Thus one voltage stabilizing element can be removed.

Title: Differential gear
Inventor: OKAMOTO KIYOMI
IPC: F16H48/06
Filed: 1989-04-24
Abstract: PURPOSE:To provide a differential gear which is excellent in power transmission capacity and stability and can reduce the reversibility from the wheel side and the under-steering tendency by clamping inner and outer free gears which are rotated in a body by carriers, and having the first and second center gears meshed with the respective free gears. CONSTITUTION:The torque of the first center gear 2 which has received input forces the second center gear 3 to rotate through free gears 4, 5 in synchronization therewith. This is because a contacting point of the first center gear 2 and the inner free gear 4 and a contacting point of the outer free gear 5 and the second center gear 3 approach each other, and the second center gear 3 receives the torque. Accordingly, though usually rotating in synchronization, in case of cornering and tight turning, the inner rear wheel requires differential operation, and if rotational difference is caused between the front and rear wheels, the second center gear 3 can not be synchronized with the first center gear 2, so that the revolution of the free gears 4, 5 is restrained, and the difference is absorbed by rotation on its axis to conduct differential operation.

Abstract: PURPOSE:To perform the reading of a color image and that of a black-and-white image with high resolution with one device by arranging plural filters keeping different angles, respectively between an original and a line image sensor, and shifting a reading position little by little. CONSTITUTION:When deviation due to the difference gamma of mounting angles (alpha) and (beta) of the filters 5a and 5b is set at a pitch of 1/3 the picture element of the line image sensor 3, positions 11a, 11b, and 11c being shifted by 1/3 of picture element on a read line 11 can be read by passing the same picture element on the line image sensor 3 through the filters 5a, 5b, and 5c.
