Title: Automatic document issuing device
Inventor: OKAMOTO TSUGIO
IPC: G07F17/26
Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To smoothly convey paper sheets while eliminating the deviation of paper sheets at the time of simultaneously feeding the plural paper sheets by moving a document to a document take-out position with a driving means in the state of pressing the document with a document pressing means. SOLUTION: The document is moved to the document take-out position by the driving means in the state of being pressed by the document pressing means. Namely, pulley gears 27 and 39 consist of a planet gear mechanism at a paper sheet discharge part and in order to convey a paper sheet 11, the pulley gear 27 is rotated in counterclockwise direction, but the pulley gear 39 is rotated in clockwise direction with the clockwise rotation of a pulse motor 25. Further, the pulley gear 39 is revolved in the counterclockwise direction by a link 37 with the rotation of the pulley gear 27 and that force is transmitted through the link 79 to an upside roller 9. As a result, the load is always applied to the upside roller 9 arranged on a paper sheet presser plate 74 in the direction to increase grip force.

Title: Shock sound preventing circuit
Inventor: KAMATA CHIHIRO
IPC: H03F1/00
Filed: 1982-06-01
Abstract: PURPOSE:To prevent a shock sound generated by an amplifying circuit by providing a switching element which turns on when a difference exceeding a prescribed value is generated by between the charging voltages of capacitors provided on the power supplying side and power supplied side of a control element inserted and connected in a current supply line. CONSTITUTION:When a power supply switch 6 is closed immediately after being opened, namely, when the power switch 6 is closed again while the output of a comparing circuit 18 is at a level H, a decoupling capacitor 11 is charged and a motor 7 and an amplifying circuit 8 are powered on by the closure of the power supply switch 6. At this time, the 1st input terminal 19 of a comparing circuit 18 is grounded through a latching transistor (TR)21, so the output signal of the comparing circuit 18 is still at the level L without going down to a level L. When the power supply switch 6 is closed again, short circuits across capacitors 9 and 10 are formed by switching TRs 29 and 30, so the amplifying circuit 8 never enters into a stable state and then generates no shock sound.

Abstract: PURPOSE:To obtain resonance characterisitcs of a BPF, obtained by connecting an LPF and an HPF, without increasing the capacity of an ROM by giving amplitude characteristics a peak by increasing or decreasing some of coefficients of a transfer function. CONSTITUTION:In the ROMs 6' and 16' of an LPF and an HPF, coefficients b1 and b2 which correspond to cutoff frequencies are stored.

The circuits 20a and 20b calculate the coefficients b2n and b2m by the coefficient b2. In the LPF, adders 1 and 2 subtract and add coefficients from and to an input signal, and the multiplier 9 multiplies the result by KL to send an output to the HPF. In the HPF, adders 11 and 12 subtract and add coefficients from and to the output of the LPF, and the multiplier 19 multiplies the result by KL to obtain an output signal from the BPF. According to combinations of logical levels of control signals (n) and (m) supplied to the circuits 20a and 20b, the depth of the resonance level of the BPF is controlled.

Abstract: PURPOSE:To control the contact area between a positive temperature coefficient thermistor and its mounting substrate and maintain the heat radiating amount of the thermistor within a prescribed range by mounting the thermistor on the substrate after adjusting the area or shape of either the cut and raised part or cut hole of the substrate. CONSTITUTION:The mounting substrate 1 of a positive temperature coefficient thermistor 5 has a cut and raised part 2 and cut hole 12 so that the contact area between the substrate 1 and surface of the thermistor 5 on which one electrode 4a is formed and the contact area between the part 2b of the substrate counterposed to the section 2 and surface of the thermistor 5 on which another electrode 4b is formed can become prescribed values. The parallelepiped thermistor 5 with the electrodes 4a and 4b on its both main surfaces is inserted between the section 2b and substrate 1. Then the electrode 4a is connected to a conductive pattern 3a formed on the surface of the substrate 1 and the electrode 4b to another conductive pattern 4b formed on the opposite surface of the substrate 1. Therefore, the heat radiating amount of the thermistor 5 can be maintained within a prescribed range and the occurrence of an attenuation current can be suppressed.

Title: Semiconductor wafer
Inventor: OTA MASAE
IPC: H01L21/322
Filed: 1987-04-20
Abstract: PURPOSE:To make the weight of a wafer light and to decrease heat capacity, by partially scraping off the rear surface of the semiconductor wafer. CONSTITUTION:A semiconductor wafer 11 is formed in a circular plate shape. The rear surface of the semiconductor wafer is scraped to a specified depth so that a plurality of concentric annular rib parts 12 are made to remain. Symbols 13 are assigned to the scraped-off parts 13. Since the parts other than a plurality of the concentric annular rib parts 12 are scraped off to the specified depth, the weight is largely decreased, and the heat capacity is largely decreased. Since the annular rib parts 12 are made to remain on the rear surface, the same mechanical strength as the strength before the scraping can be kept. Since the entire body is formed of the same material, thermal deformation due to expansion and contraction does not occur unless temperature difference is yielded in the surface. In general, the temperature change in the surface of the wafer largely depends on the heat capacity of the wafer itself. The larger the heat capacity, the larger the difference. Since the heat capacity is small in the wafer 11 and the temperature change in the surface is less, the thermal deformation can be made small.

Abstract: PROBLEM TO BE SOLVED: To detect a remarkable noise, which can not be completely removed, and to deal with this noise without resetting an entire system by discriminating the signal state of a signal line after the noise is removed by a noise removing circuit, and instructing the execution of noise countermeasure processing when that state is not normal. SOLUTION: Signal lines 110 and 111 dedicated to noise detection are provided in a signal cable 3 and noise removing circuits 101 and 103 are installed. Comparators 102 and 104 respectively compare signal potentials on the signal lines 110 and 111 after noise removing processing with a threshold value settled within a normal range and detect communication abnormality generated on signal lines L0-L7 for data transfer. Corresponding to the input of this abnormality detecting signal, a D flip-flop 102 generates an interrupting signal XIRQ for instructing the noise countermeasure processing to the CPU of a printer 2. When this signal XIRQ is inputted, the CPU decides that noise removal is not completely executed, and performs the predetermined countermeasure processing concerning noise mixture.

IPC: C04B24/38
Filed: 1987-04-17
Abstract: PURPOSE:To obtain a highly viscous concrete free of separation of cement component even when the concrete drops and flows in water by addition of a special admixture to the concrete. CONSTITUTION:A cellulosic admixture containing a defoaming agent is mixed with a polyacrylamide admixture dispersed with an inorganic salt, e.g., hydrated sodium sulfate, etc., in a proportion of 1:4 to 4:1. The special admixture is added to concrete to increase the separating resistance of concrete in water, and a melamine sulfonate-based fluidizing agent is also added to concrete to improve the fluidity of concrete. The staying of laitance on the surface of concrete can thus be prevented, and concrete can sufficiently reach even between reinforcing bars and steel frames. High-quality reinforced concrete structure can thus be constructed in water.
