Title: Semiconductor device
Inventor: NISHINO TOMONORI
IPC: H01L25/07
Filed: 1991-06-29
Abstract: PURPOSE:To make a semiconductor device a multichip-type device with good productivity by mounting the plurality of semiconductor chips on one face of a TAB tape in the longitudinal direction of the TAB tape and by bending the TAB tape zigzag for locating the semiconductor chips in three dimensions and then by sealing the TAB tape and the semiconductor chips with resin. CONSTITUTION:A TAB tape 1 is, for instance, a polyimide- or other material- made base film 2 having copper foil-formed leads 3 for electrode extraction formed on its surface. On one surface of the TAB tape 1, the plurality of semiconductor chips 4a, 4b having the leads 3 connected with electrodes 5 are placed in the longitudinal direction of the TAB tape 1. Then, the TAB tape is bent zigzag so that the semiconductor chips 4a, 4b may be placed on a region above one chip and may be eventually located in three dimensions. Under such a condition, the TAB tape 1 and the semiconductor chips are sealed. By this method, the device can be made to be a multichip-type one without increasing an occupation area and the degree of integration of the device can be increased.

Filed: 1980-12-25
Abstract: PURPOSE:To increase the number of parallel connection of slave stations, by increasing an input impedance of the slave station, through the provision of a power supply exclusively for use by a reception circuit at the slave stations. CONSTITUTION:A slave station B is provided with a power supply 16 exclusive for reception circuit. A master station A switches power supplies 1, 2 with a contact 6 of a relay 7 to transmit a transmission signal shown in Figure. A reception circuit B1 of a slave station B detects a transmitted signal (reception signal at slave station in Figure) at the base of a transistor 11 via a high input resistor 10 for amplification (current conversion). A light emitting element 13 of a photocoupler is driven with this detected signal for the detection at a reception signal circuit 15 via a photodetector 14. A return signal from a slave station turns on or off a light emitting element 18 with an oscillation circuit 20 of a return signal circuit B2, to turn on or off a photodetector 17. Thus, a return signal current as shown in figure can be flowed to a transmission line 9 with the power supply 2 of the master station.

Filed: 1989-07-18
Abstract: PURPOSE:To efficiently attain addressing of RAM by providing a circuit which sets more than arbitrary bit to an all '0' against the addition result of two address pointers designating the access addresses of RAM. CONSTITUTION:The example of cos [(2i+1)jpi/2n)i, j=0-n-1, n=8] is considered. Two ADP 6 and 7 are used as the address pointers (ADP) of RAM 5, and RAM 5 is addressed by the addition result of ADP 6 and 7. The addition result is transferred to ADP 7 so as to make it a new value. Designation masking more than five bits for the addition result of ADP 6 and 7 by a mask block part 9 is described in an instruction. The value of (2j) is stored in ADP 6, and the value of (j) an ADP 7. RAM 5 is accessed by the value of ADP 7. ADP 6+ADP 7 is newly set to be the value of ADP 7. The RAM 5 is accessed by the value. The processings are repeated n-1 times. Thus, the processing time of addressing when a constant having periodicity such as a triangle function is stored in RAM is shortened.

Filed: 1982-10-26
Abstract: PURPOSE:To completely stop an oscillation at the stopping time by operating a thyristor provided therein for protecting against an overvoltage even at the stopping time of the entire operation. CONSTITUTION:When a light emitting diode LED1 of a power source controller 4 emit a light, a phototransistor Q3 is turned ON, a switching transistor Q9 continues switching, and an output is provided at the secondary side of a transformer T2.

IPC: B65H23/188
Filed: 1980-12-26
Abstract: PURPOSE: To achieve good printing quality by exchanging the pressing force of the stopping member for the first and second paper feed mechanism alternatively thereby eliminating the loosening of the paper.  
     CONSTITUTION: A paper 3 is inserted from above where the contact between the rollers 4, 4' are released. When the paper 3 reaches to a roller 9, the roller 4' is rotated in the opposite direction thus to contact between the rollers 4, 4'. Here the contact pressure P1 between the rollers 4, 4' is lower than the contact pressure P2 between the rollers 9, 9' thereby the paper 3 is fed below. When exhausting the paper 3, the roller is rotated reversely while the contact pressure P1 between the first and second feed rollers is made higher than P2 to exhaust the paper 32 above thus to feed the paper 3 while stretching continuously.

Abstract: PROBLEM TO BE SOLVED: To smoothly feed length y sheet materials by feeding sheet materials by means of a feeding means abutting on the sheet materials carried on a sheet material carrying means and making the sheet materials on the sheet material carrying means forming a loop from a folded style and rising up abut on a guide member at its highest position. SOLUTION: When a command to feed sheets is issued, a loading tray 2 is pushed against a pick up roller 4 through a spring 3 and only one sheet of a vanner paper Sb on the utmost top of the loading tray 2 is separated, fed and guided to a nip of a pinch roller 5 and a feeding roller 6. After the tip of the vanner paper Sb passes a microswitch 7, printing starts at a record head 8. In order to avoid double feeding of the sheets after the second sheet, the loading ray 2 is separated from the pick up roller 4 and moved in a specific timing after the tip of the vanner paper Sb has passed the microswitch 7. Both ends of the vanner paper Sb on the utmost top about to make a loop from a folded condition and rise up when the sheet is to be fed are restrained by vanner paper guides 2g, 2h.

IPC: G03G15/00
Filed: 1986-08-07
Abstract: PURPOSE:To previously prevent the excessive staple processing by prohibiting the copying operation and transmitting an alarm if a sheet is left in a bin, when the finishing mode for carrying out the staple processing is selected. CONSTITUTION:When the finish mode for the staple processing is selected by a switch 155, in the sort mode by a switch 151, a CPU judges the existence of a sheet in a bin. When a sheet is left in the bin, it is judged if the copy processing is started or not, and in case of start, a copy removal display LED 160 is lighted up, and an alarm is transmitted, and the system operation is prohibited. Thus, the trouble that the excessive sheet left in the bin is staple- processed can be prevented beforehand.

Title: Preventive device of door from opening
Inventor: ANDO TAKAHIRO
IPC: E05C21/02
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To provide a means capable of surely preventing a door of a storage furniture from being opened in an earthquake, and easy in fitting work. SOLUTION: A storage chamber 2 having a rope R in this device 1 is fixed to a cabinet body part S, and a tip part of the rope R is fitted to a door T. A locking mechanism built in the storage chamber 2 gives no troubles in pulling the rope R at the normal speed while it makes it impossible to pull out the rope R and prevents the door T from being opened when the door T is opened rapidly by the earthquake and the pull-out speed of the rope R is increased or when the vibration caused by the earthquake is detected. Since the rope R is stretched between the body part S and the door T, the degree of freedom in selecting the fitting position of the storage chamber 2 and the rope R is very large. Thus, the fitting work is very easy. No defective operation due to the positional deviation occurs, and the door T is surely prevented from being opened when the earthquake occurs.
