Title: Moving handrail cleaning device of passenger conveyor
Inventor: OKAZAKI TOSHIMI
IPC: B66B31/02
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To provide a moving handrail cleaning device of a passenger conveyor having a simple and reliably intermittent operating method to reduce deterioration of the quality of the handrail belt front surface and mechanical and electrical attrition of a detecting mechanism itself, in a detecting means for the moving direction and the moving speed of a handrail. SOLUTION: In a moving handrail cleaning device, two one-way rotational clutches 22, 30 are incorporated in a shaft of a bandshaped cleaning tool renewing winding motor 21 so that respective power transmitting directions may be opposite to each other. Since one motor is shared by taking the one-way rotational clutch 22 for renewing and winding a band-shaped cleaning tool on the normal rotation side and the one-way rotational clutch 30 on the reverse rotation side as driving sources for the vertical operation of a moving direction and moving speed detecting machine 33 of a moving handrail, and also since reverse rotation stopping force of the one-way rotational clutches 22, 30 is used for braking, an inexpensive device can be formed with a simple structure.

Title: Digital data receiving circuit
Inventor: HITAI YUTAKA
IPC: H04L25/06
Filed: 1981-09-26
Abstract: PURPOSE:To receive the data which is obtained by a majority logic with a simple constitution of circuit, by providing a dividing means of the data bits. CONSTITUTION:It is supposed that the noise is contained in the data of a signal line 451. The sampling clock of a signal line 452 samples the data of the line 451 at the fall and stores the result in a shift register of a 3-bit length. For instance, the data is set at ''0'' due to the noise at the 1st sampling point. As a result, the output A (signal line 453) of the 1st bit of the register 402 is ''0''. The data is ''1'' at the next sampling point, and the line 453 is set at ''1''. Thus ''0'' which is set at the shift register at the preceding sampling point emerges at the next output B. The data is kept at ''1'' yet at the next sampling point, and the outputs A, B and C of the register 402 are set at ''1'', ''1'' an ''0'' respectively. As a result, the output of logic ''1'' is obtained at an output 456 owing to a majority logic.

Title: S/n comparator for switching of signal receiver
Inventor: TAWA SHIYOUJI
IPC: H03K3/0232
Filed: 1981-09-26
Abstract: PURPOSE:To obtain a receiving output of the optimum S/N state at all times, by providing newly a means that sets the hysteresis voltage for each signal receiver circuit when the diversity is switched. CONSTITUTION:Both DC voltages Va and Vb are amplified by DC amplifiers 11 and 12 respectively in the case of Va>Vb, and the input of the 3rd DC amplifier 13 is turned into Va' and Vb' respectively. The output is set at eV in the case of Va'>Vb', and a current flows to a diode D1 of a photocoupler 14. Thus a transistor TR1 is turned on, and the amplifier 11 is set at OV at the side of an inverse input terminal. Then the DC voltage Va of the non-reverse input is amplified as it is. No current flows to a diode D2 of the photocoupler 14 since both ends of the D2 have the same potential. Thus a TR2 is turned off, and the bias of ebV is applied to the 2nd DC amplifier 12 at the side of an inverse input terminal by a resistance R2 and a variable resistance RV2. The DC voltage Vb' of the output is set at a level obtained by amplifying the (Vb-eb)V. On the contrary, the TR2 is turned on in the case of Va<Vb. Then the DC voltage of the non-inverse input is amplified as it is for the amplifier 12.

IPC: B60R21/16
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To provide a sensor which is suitable for detecting a lateral impact and for operating equipment protecting a driver from a lateral collision. SOLUTION: A sensor 100 is equipped with a hinge-connected thin and rectangular inertia detecting mass 120. This detecting mass 120 rotates inside a housing in a state wherein a small gap is formed, and when the detecting mass 120 rotates, a flow of gas from one side of the detecting mass 120 to the other side thereof is restricted. The flow of the gas is in an inertial state and, therefore, it is affected by the density of the gas. A thin hinge 130 used herein is inserted by insert molding into the detecting mass 120 and a sensor main body and thereby the hinge 130 is so supported as not to be deformed. A reservoir 111 for storing the gas is disposed in the lateral part of a main cavity and a bias contact is formed so that it may continue to be in contact with the detecting mass 120 constantly during a collision.  Besides, an integral type connector and the shape of a seal are improved.

Abstract: PROBLEM TO BE SOLVED: To improve a heat-radiating structure in association with a connector which is two-piece type and used frequently for electrical connection to a heat generating unit, and enable the increase in heat-radiating area or heat-radiating volume even in a narrow space. SOLUTION: A terminal portion 14 of a first piece 1 to screw a heat sink 3 is engaged with a slit portion 22 of a second piece (shown by an arrow AR). A terminal 14a is electrically connected to a terminal of the second piece side. In such a state, heat is generated in a CPU 201 provided on a first printed board 203 and other electric unit 202 and a part of the heat flows in a housing of the electric unit 2 and radiated. However, a large quantity of remaining heat is passed through a guide projecting portion 21 from an extending portion 205, transmitted to the heat sink 3, and radiated in air. Simultaneously, the heat flows to a housing of the first piece 1 made of materials having low-heat resistance, and is radiated.  It is possible to assure a wide heat-radiating area because heat generated in a heating element is radiated from all of the housing of the electric unit, heat sink 3, and first piece 1.
