IPC: B60R25/32
Filed: 1999-01-16
Abstract: PROBLEM TO BE SOLVED: To prevent a lock from locking or unlocking and a hazard while a bicycle is running by connecting a safety switch circuit, which uses a bicycle running sensor as a source of canceling a command, to a receiver and by disabling the operation of a locking bar drive mechanism that moves the locking bar in a locking direction while the bicycle is in motion. SOLUTION: A safety switch circuit 10, which uses a bicycle running sensor as a source of canceling a command, is controlled by a control unit of a receiver 4. This bicycle running sensor is an oscillation sensor 9a, which is supported by a weight hooked onto an end of a spring and in which a contact plate is placed opposite to the side of the weight. Electrical signals generated intermittently through oscillation are constantly output to the receiver 4, thereby determining whether a bicycle is running. By either opening or otherwise electrically shutting down a connection between the receiver 4 and a power-supply battery 5, the receiver 4 disables the operation of a locking bar drive mechanism 3 that moves the locking bar in a locking direction or an opposite unlocking direction.

Title: Majority logic circuit
Inventor: AMANO HARUO
IPC: H03K19/23
Filed: 1988-03-01
Abstract: PURPOSE:To decide the majority of an input signal by constituting a current switch consisting of plural transistors whose emitters are connected to the output of current mode logic gates provided corresponding to plural input signals. CONSTITUTION:When (n) input signals with plural values ought to take a majority logic are supplied to input terminals (11-1n), they pass the current mode logic gates (21-2n), and appear at output terminals. When a logic supplied to each input terminal is '0', the transistor in the current mode gates (21-2n) are turned OFF, and external transistors (31-3n) are turned ON, and a current flows from a positive power source +VCC to a negative power source -VEE via resistors (R41-4n). When the logic of the input terminal is '1' the transistors in the logic gates (21-2n) are turned ON, and the current flows passes the gates to the negative power source -VEE via the resistors. Since such operation is performed independently at every input terminal, the currents proportional to the number of logic '0's of the input terminal flow from the VCC to the -VEE, and those currents are compared by a comparator 6, then, the majority logic can be decided.

The electric power reflected by the fabric 6 is proportional to gamma<2>, and the power proportional to (1-gamma<2>) is transmitted through the fabric 6. The electric power transmitted through the fabric 6 attenuates the surface 4 mixed with the absorber 8 and is reflected again by the layer 7 on the rear side of a reflector. Then the electric power proportional to alpha(1-gamma<2>)gamma'<2> returns and the rest power proportional to alpha(1-gamma<2>)(1-gamma'<2>) transmits through the fabric 6 and is radiated to the rear side of an antenna. The transmitted power passes through the surface 4 while receiving attenuation. The greater part of the power passed through the surface 4 is reflected again by the layer 7. Thus the electric power transmitted through the layer 7 is attenuated to the satisfactorily small value.

Title: Formation of fine pattern
Inventor: MATSUZAWA TOSHIHARU
IPC: H01L21/027
Filed: 1980-04-11
Abstract: PURPOSE:To permit the exact formation of a fine pattern by combining a process irradiating light with a specific wavelength at a desired part and that irradiating light with another wavelength at the whole surface wherein a positive photoresist is used. CONSTITUTION:Exposure is done on a positive photoresist film through a mask having a desired pattern by using light having a wavelength of about 200-300nm. After that, exposure is applied to the whole surface by light having a wavelength of about 350-500nm. First of all, with selective exposure applied by light having a wavelength of about 200-300nm, low luminous part and high luminous part become a positive type and a negative type respectively. Next, with the whole surface irradiated by light having a wavelength of 350-500nm, the whole surface acts as a positive photoresist in this case. Therefore, the solubility at an exposed part increase. However, the part received intense exposure by the previous exposure will leave without dissolution as the part is sufficiently hardened. On the other hand, the part received weak exposure has high solubility by the previous exposure. Therefore, the part will completely be removed by development.
