Title: Torque detector and motor assisted bicycle equipped with torque detector
Inventor: KOKATSU KYOSUKE
IPC: G01L3/14
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To simplify the mechanism of a torque detector by reducing the space and weight thereof. SOLUTION: A sprocket 2 comprises a rigid central part 29 for passing a drive shaft, a resilient stress deforming part 26 provided alternately with a plurality of protrusions 27 and holes 28 in the circumferential direction, and a rigid tooth part 26 including a plurality of teeth 24 formed on the outermost circumferential part of the sprocket 2. Stress deformation takes at the stress deforming part 26 of the sprocket itself through action of a stepping torque transmitted through the drive shaft and a chain resisting it. Consequently, the height of the protrusions 27 is lowered depending on the torque. A position detecting disc is abutted against the protrusions 27 and displacement of the detecting face of the disc is detected by means of a sensor. The stepping torque is then detected based on the detected axial displacement.  Since no additional resilient body is required, a simple torque detector realizing space saving and lightweight can be provided.

Inventor: TOKUYOSHI TAKAYA
IPC: H04Q3/58
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To extend a battery drive time by supplying power to a power supply section with a plurality of voltages so as to reduce power consumption at a power failure. SOLUTION: A commercial power supply 4 is employed for an operating power supply of a power supply section 14 in the normal operation so as to supply power with a set normal state operating voltage. When a power failure detection section 12 detects a power failure, the detection section 12 informs a central control section 13 of the power failure to instruct the power supply section 14 to use a battery 16 with a low voltage for power failure, and the power supply section 14 switches the operating power supply. When the power supply section 14 selects the battery 16 for the operating power supply, the central control section 13 instructs the power supply section 14 to supply power of the battery 16 with a voltage for a power failure and the power failure detection section 12 monitors the restoration of the power.  When the detection section 12 detects the restoration of power and the central control section 13 receives the notice, the control section 13 instructs the power supply section 14 to return the use of commercial power supply 4 with the normal operating voltage. Thus, the service life of the battery 16 is extended through the changeover of the supply power.

IPC: G11B7/24
Filed: 1989-11-24
Abstract: PURPOSE:To obtain the information recording medium capable of obtaining a large power margin in recording by providing a specified auxiliary film adjacent to at least one surface of a recording film. CONSTITUTION:The substrate of the information recording medium is irradiated with an energy beam to form a recess or a hole in the recording film. The auxiliary film consisting essentially of at least one kind of element selected from a group consisting of Se and S is provided adjacent to at least one surface of the recording film.

The Se, S and Te are the chalcogenide elements and form a homogeneous solid soln. Since the viscosity of the molten state is increased by the incorporation of Te, the inner diameter of the rim of the formed hole is decreased.

Title: Waste heat recovery boiler device
Inventor: SHIGENAKA TOSHINORI
IPC: F22B33/14
Filed: 1987-12-03
Abstract: PURPOSE: To shorten the starting time while reducing NOx by coupling an auxiliary steam header with a high pressure main steam pipe through an auxiliary steam bypass pipe provided with an auxiliary steam stop valve and an auxiliary steam regulation valve. CONSTITUTION: Point H of an auxiliary steam header 38 is coupled with Point 1 of a high pressure main steam pipe 27 through an auxiliary steam bypass pipe 48a provided with an auxiliary steam stop valve 49 and an auxiliary steam regulation valve 50. Auxiliary steam from the header 38 is introduced through the pipe 48a, the pipe 27, a super heater 14 and a drum steam outlet pipe 26 to a high pressure drum 13 thus preventing pressure drop thereof. Consequently, inner pressure of a high pressure boiler can be held at a substantially same level as the pressure of the auxiliary steam header. Since inner pressure of a low pressure boiler can be held higher than the atmospheric pressure, starting time can be shortened and since the exhaust gas temperature increases, NOx can be reduced at the time of starting.

Title: Handy communication unit including portable telephone set
Inventor: SATO SADAO
IPC: H04B1/3822
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To reduce adverse influence to a human body by means of an electromagnetic wave, to give ease feeling to a user, to improve the radiation characteristic of the electromagnetic wave and to facilitate the pull-out/pull-in of an antenna even in a calling posture by fitting the antenna fitting position of a handy communication unit to the lower part of a main body. SOLUTION: An antenna fitting position while a handy communication unit is used is set to the lower part 3 of a main body and it is kept away from brain and a heart as far as possible. Since the antenna position during use is set to the lower part 23 of the main body, adverse influence to the human body owing to an electromagnetic wave is reduced and ease feeling can be given to a user. The radiation characteristic of the electromagnetic wave improves, the pull-out/pull-in of the antenna become easy and production cost can be made almost similar to a former case. Even if the most part of the antenna is pushed into the main body 1, or it is pulled out halfway, the maximum point of electromagnetic wave voltage is prevented from being closely stuck to a brain cell which is most anxious in the human body and the effect in health and mind is given.
