Title: Hot air flow space heater
Inventor: HIRAISHI SHUNICHI
IPC: F24H3/06
Filed: 1985-03-04
Abstract: PURPOSE:To provide the titled air flow space heater having a high safety, unrequiring an installation space within the house and easily carrying out the installation work by providing an indoor air passage communicating with two ducts, and a burner heating indoor air through an airtight wall, and providing a blower in the indoor air passage. CONSTITUTION:When a blower 20 is driven by the control unit 7 of a grill 1 and a burner 14 is actuated, an indoor air circulating fan 21 and a waste gas fan 22 rotate. For this reason, air within a room 4 to be heated is introduced into the indoor air passage 9 of a main space heater body 8 via a suction port 2 and a duct 10. Further, external air sucked up from an external air intake port 12 is sent into a combustion chamber 13. Indoor air entering the indoor air passage 9 carries out indirect heat exchange with a combustion gas rising up in a heat exchanger 16 and is heated. Indoor air is passed through a duct 11 and an exhaust port 3 and is returned to the room. Further, the waste gas which has completed the heat exchange is guided to a waste gas passage 18 and thereafter is discharged to the outside through an exhaust port 19 by means of waste gas fan 22.

Inventor: SAKAKIBARA TAKAAKI
IPC: B23Q15/00
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To form a workpiece surface in a shape after machining symmetrical relating to the center line in a sub-scanning direction.

Title: Coin sorter
Inventor: SHIMOKURA KOICHI
IPC: G07D5/08
Filed: 1988-02-25
Abstract: PURPOSE:To make unnecessary a software, etc., for an A/D conversion and a numeric value processing, and to drastically reduce the costs of the title discriminator by discriminating the falseness of coins only with the logical comparison between a detecting pulse and a comparing pulse. CONSTITUTION:When the input of the coin is detected, a presetting counter 30 is set at a value S1 by a detecting signal. The counter 30 outputs the positive comparing pulse when the clock pulses in the prescribed piece are inputted from a detecting signal input time point T1. On the other hand, a since wave signal whose phase is delayed is outputted by the transit of the coin from a detecting part 23, and it is shaped into a rectangular wave by a waveform shaping device 26. At the time of T2 when the rectangular wave falls, a monostable circuit 27 outputs the positive detecting pulse having a width W. The AND of the both pulses can be obtained by an AND circuit 33. When the coin is normal, the comparating pulse is included in the width W, the output of the circuit 33 is at an H, it is inputted to a counter 34, and it is decided to be the normal coin when its counted value exceeds a prescribed value M. When the coin is false, the counted value of the preset counter 30 does not exceed the value M, and remains at an L.

Title: Digital error generating circuit
Inventor: YAMAZAKI SHIGERU
IPC: H03K3/84
Filed: 1981-03-24
Abstract: PURPOSE:To simply produce a random error without carrying out a D/A conversion, by causing an error at a random bit position of a series of digital data signals which are successively transferred. CONSTITUTION:It is supposed that four FF outputs forming an artificial random code generating circuit 1 are set at ''1001'' and a 16-notation counter 2 is set at ''0000'' respectively. As a comparator 3 produces no coincidence signal 8, a digital data signal input 4 is converted directly into a signal output 5. When the counter 2 reaches ''100'', the comparator 3 delivers the signal 8. As a result, the signal polarity is inverted by an OR circuit 7 for the input 4 to be converted into the output 5. In other words, an error is included into the digital data signal. At the time, the signal 8 is converted into a clock input of the circuit 1 and the FF output of the circuit 1 proceeds to the next state.

Title: Constant voltage power circuit
Inventor: HASHIMOTO KYOSUKE
IPC: G05F1/56
Filed: 1987-02-27
Abstract: PURPOSE:To reduce a stand-by current and an input/output voltage difference by operating a 1st TR in its saturation area and increasing the resistance value between the base of a 2nd TR and a positive power source and the resistance value between the base of a TR and a constant voltage diode. CONSTITUTION:Transistors TR 2 and TR 1 turn on by the application of an input voltage and a capacitor C3 beings to be charged, thereby outputting VOUT. When the charging voltage of the capacitor C3 exceeds the Zener voltage of the constant voltage diode, the TR 3 turns on and TR 2 and TR 1 turn off, so that the capacitor C3 begins to be charged. When the discharging voltage of the capacitor C3 goes to under the Zener voltage, it is returned to the initial state. At this time, the TR is used in its saturation area at all times and the values of the resistances R4 and R6 are made large to reduce the input/output voltage drop and also reduce the stand-by current of the circuit.

Title: Non-backlash overload clutch with misalignment absorbing function
Inventor: FUJII SHUNJI
IPC: F16D7/08
Filed: 1989-02-27
Abstract: PURPOSE:To facilitate the absorbing of misalignment by arranging a driven plate formed with a torque transmission element holding through part between a hub formed with a torque transmission element holding bottomed part and a pressure plate with a gap kept between them. CONSTITUTION:A driven plate 40 is fixed between a hub 20 and a pressure plate 30 with a gap kept between them. Consequently, when the hub 20 is mounted on a shaft A, and the plate 40 and a coupling flange 13 are mounted on a shaft B, the plate 40 can relatively move to the hub 20 in an axial direction even if a space error D exists, and tilt to absorb the error even if an angular error exists between the shaft A, B. When a clutch is not under an overload during its rotation for torque transmission the pushing pressure of the plate 30 brings a ball 12 into two-point contact with a V-shaped notch 41 of the plate 40 and a V-shaped long groove 26 (torque transmission element holding bottomed part) of a flange 22 of the hub 20 to rotate both the shafts A, B in one united body. An overload clutch 10 can therefore absorb the angular and space errors even if they occur during the rotation of the clutch.
