Title: Manufacture of electric power steering device
Inventor: SAKAI AKIO
IPC: B23F13/02
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of an electric power steering device capable of carrying out a measurement of parts further simply and at a high accuracy. SOLUTION: A predetermined dimension relationship is established between an outer diameter surface 103b and a tooth surface 103c by machining the outer diameter surface 103b and the tooth surface 103c of a worm gear 103a using single formed tool T. Accordingly, a tooth surface shape can be presumed at a high accuracy by measuring the outer diameter surface 103b which can be generally measured relatively simply and at a high accuracy without directly measuring the tooth surface 103c of the worm gear which is conventionally difficultly measured. Thereby, a management of a back-lash of the worm gear 103a and a worm wheel, for example, can be severely carried out.

Title: Temperature sensing valve
Inventor: MIYAHARA SHINJIRO
IPC: F16K31/70
Filed: 1986-05-27
Abstract: PURPOSE:To make a temperature sensing valve compact and increase the responsiveness to a temperature, by communicating a water supply port with a cold water discharge port through an element wire clearance of a driving spring formed of a shape memory alloy. CONSTITUTION:A valve member 28 is movable in a housing 21 by means of a driving coil spring 29 formed of a shape memory alloy. When a cold water is supplied from a water supply port 22, a spring constant of the driving spring 29 becomes small, and accordingly the valve member 28 is moved toward a bias spring 30. As a result, a discharge port 27 is brought into isolation from a hot water discharge port 24, and simultaneously the water supply port 22 is brought into communication with a cold water discharge port 23 through an element wire clearance 32. On the other hand, when a hot water is supplied from the water supply port 22, the discharge port 27 is brought into communication with the hot water discharge port 24.

Title: Recording and reproducing device using disk recording medium
Inventor: YAMAMOTO NAOKI
IPC: G11B19/20
Filed: 1986-05-27
Abstract: PURPOSE:To obtain a compact and thin recording/reproducing device by using a shift means which shifts a holding means so that a head is floated over a disk recording medium for a prescribed period in response to the start of a motor. CONSTITUTION:A piezoelectric element 14 is displaced by a piezoelectric element drive circuit 15 in response to the start of a motor and before the start of the motor to raise up a head lift lever 11 toward B. Then a head 3 is separated from a disk recording medium 2 by a head lift pin 13. Under such conditions, a motor 1 is rotated and just small starting torque is needed owing to a small load torque. When the circuit 15 is turned off with increase of the rotational frequency of the motor 1, the head 3 is kept floated up by an air flow produced by the revolution of the medium 2. When the diameter of a coil winding is reduced, the starting torque is reduced and the current consumption is also reduced in a rated mode in terms of the features of the motor 1. Thus it is possible to obtain a compact and thin recording and reproducing device.
