Patent JP-H01273780-A (JP)
Title: Brake device for bicycle
Inventor: ISHIBASHI HIDEYUKI
IPC: B62K19/38
Filed: 1988-04-27
Abstract: PURPOSE:To prevent lowering of durable performance, by a method wherein a radius ranging between the pivotal support point of a brake body to hold a brake shoe and the exerting point of a control force is reduced so that it does not interface with the constituting member of a bicycle, and the control force of a control wire is transmitted to the brake body through a boosting mechanism. CONSTITUTION:When, with a brake lever controlled, a control wire 20 is pulled frontward (in a direction A), brake bodies 28 are rotated in a direction B around respective bolts 29 through a pulley 33 and a connecting rod 32, and brake shoes 30 are forced into pressure contact with the both sides of a rim 11b of a rear wheel 11. In this case, a force exerted on the rod 32through the action of a boosting mechanism by means of the pulley 33 is increased two times as large as that on the wire 20, and a stroke is reduced to 1/2. Thus, even if a working radius R ranging from a pivotal support point 01 of the brake body 28 to a working point 02 of a control force transmitted through the rod 32 is reduced to half that of a conventional type, the same brake force as that of a conventional type is provided. Since the same force as that of a conventional type may be exerted on the control wire 20, the wire 20 is prevented from excessive stretch and lowering of durability.

Inventor: KUWABARA TADANORI
IPC: E02D3/12
Filed: 1982-06-15
Abstract: PURPOSE:To obtain a highly accurate inclination angle even when a mast is bent by a method in which a steel wire is laid tensely between a sensor fitting base and the lower part of the mast, and an inclination sensor is set to the sensor fitting base. CONSTITUTION:A steel wire 12 is laid tensely through a turn buckle 13 between a sensor fitting base 10 and the lower part of a mast 5b, and an inclination sensor 14 is set to the sensor fitting base 10. During the period when the ground is treated and hardened by a treatment machine 5, when a deflection occurs in the mast 5b of the treatment machine 5, the steel wire 12 in the mast 5b represents the inclination of straight line between the top and lower part of the mast 5b in spite of the deflection of the mast 5b. Thus, a true inclination angle from the top to the lower part of the mast 5b, given by the steel wire 12, is detected by a differential pressure transformer type sensor on the fitting base 10, and exact inclination between the upper end and top of the treatment machine 5 is displayed on an inclinometer 18 in a control room.

Title: Operation deciding method for central processing unit
Inventor: KOMATSUDA NOBUKO
IPC: G06F11/00
Filed: 1985-05-14
Abstract: PURPOSE:To detect abnormal operation of a central processing unit CPU efficiently by a simple circuit by deciding that the CPU operates normally when a signal having a specific period is sent out to a separation signal terminal. CONSTITUTION:When an execution instruction is read in the CPU 1 from an external storage device, an address signal is outputted to the external storage device and an address and data separation signal 7 is outputted periodically. An integration circuit 2 integrates the address and data separation signal 4 outputted from the CPU 1 to shape the waveform into a level signal, which is outputted. The integral output signal 8 is inputted to a warning inhibition circuit 3 together with a warning inhibition signal 9 and the circuit 3 ORs the two inputs and outputs the result. In operation mode wherein the CPU 1 is not in abnormal operation, but the address and data separation signal 7 is not outputted, the warning state of the integral output signal 8 is inhibited by the warning inhibition circuit 3 and a warning signal 10 is not outputted. Consequently, the warning signal 10 is outputted only when the CPU 1 is in abnormal operation.

Title: Coal, petroleum or gas burning burner
Inventor: ARUBAATO DANIERU RARIYU
IPC: F23D14/22
Filed: 1989-04-25
Abstract: PURPOSE: To reduce discharge of NOx by providing a flame stabilizing ring with a first part projecting radially inward into a central passage, and a second L-shaped part projecting radially outward from a burner nozzle and receiving a retractable gas ejector. CONSTITUTION: A flame stabilizing ring 118 blocks secondary air flow through an annular surrounded region 86 between a tubular burner nozzle 44 and a gas region sleeve 84. In case of coal firing, flame is combined on the inside of the ring 118 with regulated secondary air introduced through inner and outer annular passages and discharge of NOx is reduced. In case of oil firing, secondary air flow is influenced by the ring 118 and an air separation vane to reduce the quantity of oxygen for oil flame in the region immediately in the downstream of a burner port thus suppressing generation of NOx . In case of gas firing, flame is stabilized extremely because a retractable and turnable gas ejector 48 is shielded by the ring 118.
