Title: Automatic document feeder and image forming device
Inventor: FUKUCHI MASAKAZU
IPC: G03G15/00
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To detect a staple, with a simple constitution, while saving space by detecting stapled documents, so as to prevent the occurrence of trouble such as paper jamming. SOLUTION: In this automatic document feeder 1, a detecting member 50 for detecting the staple is moved in a direction perpendicular to the feeding direction of a document, to execute the detection, by a scanning means 60, so that the stapled documents can be detected with the simple constitution. Further, when the staple is detected, the feeding of the document is inhibited not to make a copy. Thus, the occurrence of the trouble such as the paper jamming can be prevented.

Title: Equalizing circuit
Inventor: SHIMAUJI MASAHIRO
IPC: G11B5/09
Filed: 1987-02-23
Abstract: PURPOSE:To reduce the negative peak and to improve the influence of reading errors by attenuating by a prescribed extent the input approximation waveforms advanced and delayed relatively by the prescribed time against an input signal and at the same time controlling the half value width by a low-pass filter to add it to the input signal. CONSTITUTION:The isolated reproduced waveform of a thin film head of a waveform S0 includes a negative peak (a) earlier than the center peak by a time taua and a negative peak (b) later than the center peak by a time taub respectively. Here the peak of an output signal S5 of a low-pass filter 8 can be set at a similar level to the negative peak of the output signal of a delay line 3 by satisfying an equation I, i.e., tau1=(taua+taub)/2 and tau3=taud, where tau1 shows the total delay time of a delay line 1 together with tau3 showing the total delay time of a delay line 3 and taud showing the delay time of the low-pass filter 8 respectively. Then a waveform S5 obtained by the equation I is added with the output signal of the line 3 by an adder 5. As a result, the negative peaks (a) and (b) contained in the waveform S0 can be eliminated and the influence of reading errors due to said negative peaks is improved.

Title: Sealed bag containing mini gas-cylinder
Inventor: KOMIYA SHOHACHI
IPC: B65D81/07
Filed: 1988-02-24
Abstract: PURPOSE:To obtain a sealed bag in which the title gas cylinder is contained in a simple structure, high safety, light and compact, freely portable and easily handing, by providing a weakened part in which the sealed bag can be opened from the outside for a mini gas-cylinder and by forming the bag to have enough volume to contain all gas emitted from the mini gas-cylinder. CONSTITUTION:In a sealed bag in which a mini gas-cylinder is contained, weakened parts 12 comprising scored lines in the peripheral directions are provided around the surface of just the middle point of the full cylinder length. The sealed bag 20 is kept to be in a completely sealed condition by the heat- sealed part 21 at the periphery. The bag is large enough so as the gas of the mini gas-cylinder 10 can be all contained almost at an ordinary pressure. When the mini gas-cylinder 10 is unsealed, the sealed bag 20 is forced to open and the cylinder is forced to fold by keeping the weakened parts 12 comprising scored lines outwardly with the external force at both ends 11 of the cylinder. As a result, external forces are concentrated in this part and hence the bag is easily broken and a part of the mini gas-cylinder 10 is broken and then the internally compressed gas is instantaneously filled in the sealed bag 20.

Title: Ultrasonic sensor
Inventor: FURUSAWA KOICHI
IPC: G01S7/524
Filed: 1989-02-20
Abstract: PURPOSE:To enable sure detection of an object positioned at a close distance from an ultrasonic sensor by generating a short-circuit gate signal for a prescribed time after a drive for a prescribed time after the end of a transmission gate signal and by short-circuiting thereby the opposite ends of an ultrasonic vibrator. CONSTITUTION:An ultrasonic vibrator 4 is driven by a driving circuit 3 on the basis of a signal output generated from a transmission gate generating circuit 1. After the vibrator 4 is driven, a short-circuit gate signal for a prescribed time is generated from a short-circuit gate generating circuit 2 and thereby an analog switch 5 is closed. By this closure, the reverberation of the vibrator 4 stops in a short time. In the case when there is a reflective object in the vicinity of a sensor, a reflection wave is obtained immediately after the drive of the vibrator 4. A signal of this wave is obtained from the vibrator 4, amplifier 6 and given to a detecting circuit 7. By the circuit 7, an envelope signal thereof is detected and given to a comparator circuit 8. The circuit 8 compares an output of the circuit 7 obtained after the end of a short- circuit gate with a prescribed threshold value and gives an output circuit 9 a signal exceeding the threshold value. The circuit 9 outputs this signal as an object detection signal to the outside.

Abstract: PURPOSE: To make a connection definite by fixing a lead onto a film carrier using an elastic film of a heat-proof electric insulator and by pressure-welding the electrode terminal of a semiconductor element here over heating.  
     CONSTITUTION: On mount 24 on which polyimide film 23 is mounted at least at a part made of transparent quartz, polyimide film 23 with lead 22 on its surface is mounted with lead 22 up. Next, bump 21, an electrode terminal provided to semiconductor substrate 20, is made in contact with the end of lead 22 and bonding tool 25 with adsorbing vaccum hole 26 is arranged on substrate 20.

Abstract: PURPOSE:To inhibit the increase of leakage currents resulting from a Si rubber and a platinum group catalyst by compounding the catalyst containing no halogen compound when using the addtional type Si rubber containing no alkalic metallic impurity. CONSTITUTION:1-10wt.pt. diorganopolysiloxane, one molecule thereof has not less than three hydroxyl groups, is compounded to 100wt.pt. organopolysiloxane having alkenyl groups, that is, diorganopolysiloxane, both terminals of molecular chains thereof have vinyl grups or aryl groups, and a material manufactured in such a manner that a Si resin liquid into which a Pt compound, such as (CH3)4Pt, (CH3)2PtCO, etc. is mixed is applied to the P-N junction of a semiconductor element, heated at 65-200 deg.C and cured is used as the platinum group catalyst containing no alkali metal and halogen compound. As Si resin composition according to such constitution stabilizes the surface of the semiconductor element particularly for a large aperture, high dielectric resistance and large currents, results in the small change of leakage currents even at a high temperature and improves reliability.
