Abstract: PURPOSE:To ensure high speed response characteristics over a wide band range, without damaging workability when a photo detector module is assembled. CONSTITUTION:A carrier 10 for mounting a photo detector 11 is constituted of insulator like alumina. An electrode pattern 21 for applying bias and an electrode pattern 22 for outputting signals are formed covering two surfaces of a surface 31 on which the photo detector 11 is mounted and an electrode surface 32 for electric connection. On the two surfaces of the surface 31 and the surface 32, air gaps 41 and 42 are formed between the electrode patterns 21 and 22. A metal plate 24 for assembling which is soldered to the carrier 10 is formed on the surface facing the surface 32. An air gap 43 is formed between the electrode pattern 22 and the metal plate 24. By the effect of these air gaps, capacitance of the carrier 10 can be reduced.

IPC: B65H31/24
Filed: 1993-06-25
Abstract: PURPOSE:To improve a loading property by changing a loading method of a sheet bundle on a stack means by a method wherein whether the loading method is of a stapling mode or a non-stapling mode is judged in the title after treater which delivers the sheet bundle to a stacker. CONSTITUTION:When a sheet bundle loaded on a tray means 403 is moved to a stacker, a method for handling the sheet bundle is changed according to whether a stapling process has been carried out or not.

Filed: 1989-07-13
Abstract: PURPOSE:To shorten the time required for the disturb test after production by selectively supplying plural driving voltages to a memory cell in response to indicating outputs of the normal mode and the test mode. CONSTITUTION:When a test signal T in the low level is given, a MOSFET 63 is made conductive in a power supply circuit 71 for test, and the potential of a node N61 is supplied to memory cell driving lines 60a and 60b and becomes a voltage Vcc - Vth lower than a supply voltage Vcc by a threshold voltage Vth of a MOSFET 62. In a power supply circuit 70 for normal operation, a signal the inverse of T in the high level is received by the gate of a MOSFET 61 and it is made non-conductive. Consequently, the potential Vcc is not transmitted to lines 60a and 60b, and a potential is given to lines 60a and 60b from the circuit 71. Consequently, the low driving voltage Vcc - Vth is supplied at the time of the disturb test.

Title: Timer controller
Inventor: SASAKI MASAO
IPC: H04N5/63
Filed: 1988-07-20
Abstract: PURPOSE:To improve the serviceability and recognizability of the title controller by sending sound and/or video signals when timer time comes. CONSTITUTION:When, for example, a timer is set so that power supply can be turned on at specific time Ta, the data are stored in a RAM 27 and comparison between the data and the timer count Tb of a time piece 28 is started. When the timer count Tb coincides with the data stored in the RAM 27, whether the power supply to a television receiver 13 is turned on or off is confirmed. When the power supply is turned off, control signals are outputted so that the power supply to the receiver 13 can be turned on and the channel of the receiver 13 can be set to a specific channel. When the power supply to the receiver 13 is turned on, only the control signal which selects the channel is outputted. Thereafter, picture and sound data are respectively outputted from a picture memory 29 and sound synthesizer 30. Thus the serviceability and recognizability of this timer controller can be improved.

IPC: G01S17/10
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To accurately measure distance even if there are large reflection pulses from an object at the rear of a target by allowing an quantity-of-light control means to control a quantity-of-light variable part in accordance with the quantity of light of initial light pulses through an external light path and light pulses through an internal light path. SOLUTION: A light pulse light transmission means 100 selects either an external light path 106 for transmitting light pulses toward a target 105 or an internal light path 107 for transmitting light pulses for obtaining the reference level of light pulses in a state where the quantity of light is balanced toward the inside of a device, thus emitting the light pulses. A light pulse reception means 101 receives light pulses through the external light path 106 or the internal light path 107, converts them to electrical signals, and output them to a time measurement means 102. A quantity-of-light control means 103 controls a quantity-of-light variable part 104 and balances quantity of light for making equal the quantity of received light of light pulses through the external light path 106 and the internal light path 107.  The time difference between the emission timing from the light transmission means 100 and the reception timing from the light reception means 101 is measured by the measurement means 102, thus obtaining distance.

Title: Electrical dust precipitator
Inventor: MOROHASHI HISAO
IPC: B03C3/16
Filed: 1981-11-12
Abstract: PURPOSE:To eliminate the degradation in the performance and troubles owing to deposited dust with simple construction by removing fixed electrodes for precipitating dusts from an electrical dust precipitator, and using liquid columns formed independently in spaces in lieu of said electrodes as dust precipitating  electrodes. CONSTITUTION:Needlelike discharge electrodes 11 are provided to the bottom ends of the 1st electrodes 9, and the top ends thereof are connected to one electrode of a high voltage power source 13 via a connecting member 12. If liquid 14 such as, for example, water, which is conductive with high voltage electricity is filled in a liquid well 4 and the liquid 14 in the well 4 is scooped into jackets 5 by a circulator, the liquid 14 filled in the jackets 5 falls toward the well 4 through small holes 10, thus forming many liquid columns 15 enclosing the electrodes 9. When the other electrode of the power source 13 is connected to the liquid 14 in said state, the columns 15 form the 2nd electrodes of the polarity differing from that of the electrodes 9, thus generating corona discharge toward the columns 15. When dusty air is fed through an air intake port 2 toward vent ports 6, powdery dust sticks to the columns 15 and falls together with the liquid into the well 4.

Title: Method for hot rolling
Inventor: YORIFUJI AKIRA
IPC: B21B27/00
Filed: 1988-07-22
Abstract: PURPOSE:To prevent linear flaws by pressing only edge parts by use of a roll whose rotating axis is orthogonal to the transfer direction of a stock to be rolled and is slanted to a surface of the stock and whose surface is grooved in the axial direction for a rough rolling stage consisting of vertical and horizontal rollings. CONSTITUTION:A grooved roll 7 is installed against the surface of a stock 1 to be rolled so that the rotational axis of the roll 7 makes an angle of alphato an edge part 3 and is supported by a roll shaft 8. Grooves 7a of the roll 7 are parallel to the roll axial line and are equally spaced by a pitch P and have the same depth of (d). A surface shape of the roll 7 is not limited to a straight shape and a proper concaved shape such as a hyperbolic curved shape is also employed. The purpose of the roll 7 is to cut roughs generated on the edge 3 of the stock, so that roll support is sufficient by cantilever type because a necessary drafting force is small. The roll 7 is enough to be a non-driven roll because the roll 7 is driven by the stock 1 even if the roll is driven by a driving device. Hence, linear flaws in hot rolling of metal stocks are prevented from being generated and the quality of products is improved.
