Title: Flattened seat structure of automobile
Inventor: ARAI TOMIJI
IPC: B60N2/36
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To improve workability to automatically carry out rotation of a leg member by supporting a seat cushion from below by the leg member by making the leg meber in a vertical state at the time of making the seat cushion in a roughly horizontal reversing state. SOLUTION: A seat frame 7 is locked when it is retreated to a flattening position by sliding backward with a seat cushion 5 and a seat back 6. Thereafter, the overall seat cushion 5 is revolved to the front side around a front end part fulcrum P1 while pulling it up, and it is made in a reversing state with its back surface 5a up. At this time, pulling force is applied on a leg member 9 from a connecting member 12, the leg member 9 is made in a vertical state, a lower end part makes contact with a pedestal 22, and it is possible to support the seat cushion 5 from below. Consequently, since the leg member 9 is automatically rotated and made in the vertical state, workability becomes excellent.

Abstract: PURPOSE:To make a system small in size and to enable the detection of rotation by means of a simple system by a construction wherein an entire optical system from a light source to a photodetector is formed of optical waveguides such as optical fibers. CONSTITUTION:A beam of light from a semiconductor laser 1a is made to fall on a single-mode optical fiber 9 and divided in two by an optical fiber coupler 14a. The two beams pass through optical fiber couplers 14b and 14c respectively and then both pass through an optical fiber coupler 14d. Then, they are propagated clockwise and counterclockwise respectively through an optical fiber loop 11. The beams propagated in multiple times through this optical fiber loop 11 are passed through the optical fiber couplers 14b and 14c respectively and transduced into electric signals by photodetectors 4a and 4b. The stabilization of a resonant point is implemented by using the beam propagated counterclockwise through the loop 11, while the detection of rotation is implemented by using the beam propagated clockwise therethrough.

Filed: 1995-04-13
Abstract: PURPOSE: To modify a learning value when retaining control is started on the basis of a wrong learning value so as to perform stable retaining control in a valve timing controller for an internal combustion engine. CONSTITUTION: A hydraulic variable mechanism (VVT) 25 changes valve timing. A linear solenoid valve(LSV) 55 controls oil pressure supplied to the VVT 25. An electric control unit (ECU) 80 controls the LSV 55 for the purpose of obtaining valve timing matched to the operation condition of an engine 1 so that a real phase is matched to a target phase according to the operation condition. When phase deviation between the real phase and the target phase becomes below a predetermined value, the ECU 80 controls to retain the LSV 55 on the basis of a predetermined control value so as to retain a phase at the point of time. When the phase keeps a certain stable condition, the ECU 80 learns a learning value applicable as a control value for retaining control.  When the real phase is changed by the retaining control and the phase deviation is increased larger than the predetermined value, the ECU 80 changes the learning value by appropriately increasing/decreasing it.

Title: Stabilizing circuit of a/d converter
Inventor: ENDOU KENJIROU
IPC: H03M1/08
Filed: 1979-07-13
Abstract: PURPOSE: To prevent previously the malfunction caused by the level fluctuation, the noise and other factors and thus ensure the stabilization of the A/D converter, by inhibiting the converting action unless the analog input signal has variation of the fixed level or more.  
     CONSTITUTION: In addition to adder 12 and latch circuit 14, local D/A converter 15 and coefficient unit 16 are provided. Addition signal z applied to A/D converter 13 shows a continuous variation of 0.5x in correspondence to the variation of analog input signal x as well as a discontinuous variation of 0.5ΔX (ΔX: the minimum quantization accuracy of converter 13) every time the addition signal crosses the level prescribed by the threshold level of converter 13. On other words, the blind sector of 0.5ΔX is added to converter 13. As a result, even if signal x has a mimute change around the level prescribed by the above-mentioned threshold level, the so- called variance due to the fluctuation of the minimum bit LSB of converter 13 is never caused. Thus the state at that moment can be held steadily.

IPC: D06F25/00
Filed: 1989-04-07
Abstract: PURPOSE:To eliminate wasteful drying time and terminate washing in a satisfactory drying state by starting drying from a starting time set based on a drying required time selected by a load quantity setting switch and a termination time. CONSTITUTION:An operation part 16 has a load quantity setting switch 20, and this switch 20 is divided into each switch in which the magnitude of the load quantity is set stepwise, for example, five-staged switches of small load quantity to large load quantity. The limit of washing drying with a large quantity of clothes is switch '5', that with an extremely small quantity of clothes is switch '1', and switches '2, 3, 4' are provided between them. A drying required time calculating means 18 calculates the drying required time necessary for drying step from the load quantity set by the load quantity setting switch 20. The drying starting time is set on the basis of the drying required time and a termination time selectively set. As the drying required time is a time suitable to the load quantity of the clothes, washing step can be precisely terminated at the termination time selectively set.

Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To prevent a nail from slipping off by vibration and the like by constituting a shaft part with a screw part whose lead angle is not constant along a longitudinal direction, and recessed/projection parts which are not formed in a screw shape of a head part side. SOLUTION: A part 12a of a shaft part 11 of a nail 1 is formed as a screw part A formed with a plurality of grooves having a lead angle α, and a part 12b is formed as a screw part B formed with a plurality of grooves having a lead angle β. A plurality of parts 12c are annular bodies along a circumferential direction as recessed/projection parts which are not formed in a screw shape. In the relation between respective lead angles α and β, the angle β is larger than the angle α. Namely, a strike resistance is reduced when the nail 1 is struck, in the screw part B (12b), and a pull-out resistance is increased in the screw part A (12a). The nail 1 is slipped out while turning by vibration and the like, the nail 1 is difficult to turn since the lead angle α of the screw part A (12a) is smaller than the lead angle β of the screw part B (12b).  As a result, the nail 1 is difficult to slip off.
