Title: Toilet seat toilet-led closing mechanism
Inventor: ARAKAWA MASAFUMI
IPC: A47K13/12
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To constitute an inexpensive closing mechanism, by providing a small- sized, inexpensive drive means by driving a drive means, thereby applying initial torque to an opened toilet seat or a toilet lid in the closing direction, and then by slowly lowering it to a closing position via a slow-down mechanism. SOLUTION: When a seating sensor is turned off after a person stands up and moves away from a toilet after defection or urination, a nozzle-moving motor 7 is actuated after about one minute, and a gear 5 on the nozzle side is rotated to move a gear 4 on the base side rearward, thereby moving a nozzle 6 deepest in the recess. Consequently, although it comes into contact with a stopper and stops moving by continuously applying torque to the nozzle-moving motor 7, a cam 8 on the motor side butts against a cam 10 on the toilet lid side, initial torque for moving an opened toilet lid 3 downward is transmitted to the toilet lid 3 from the cam 10 on the toilet lid side. In response to it, the toilet lid 3 starts to move downward by gravity, and then the toilet-lid slowd- down part of a slow-down unit 9 acts to move the toilet lid 3 slowly, thereby covering the toilet seat 2 with the lid.

Title: Disk controller
Inventor: AKIBA KAZUHIKO
IPC: G11B19/02
Filed: 1999-12-17
Abstract: PROBLEM TO BE SOLVED: To solve such a problem that the delay of response to a host device or the update process of control information becomes the primary factor for the time-out of the host device by the time delay because the seek operation is generated when the control information is updated by a disk controller and the above update process is carried out by the internal operation having no concern with the host device. SOLUTION: The measure to cope with this problem is realized by providing a nonvolatile memory for storing the control information in the disk controller. Then, the reduction of the start time, the improvement of the throughput, and the improvement of the data reliability are attained.

Title: Control device for working machine having expansion boom
Inventor: HIRAMI KAZUHIKO
IPC: B66F9/24
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To more speedily, safely, and adequately perform automatic storage of an expansion boom, by turning the expansion boom to a storage-time turning position when a present boom hoisting angle is larger than a turning tolerance angle, and by turning the expansion boom after raising it to the turning tolerance angle when the present boom hoisting angle is smaller than the turning tolerance angle. SOLUTION: A normal boom hoisting angle 'θx' corresponding to a present turning angle of an expansion boom is read out from a memory (S5). It is determined whether a present boom hoisting angle of the expansion boom is larger than the normal hoisting angle 'θx' selected in S5 (S6). When it is larger than the normal hoisting angle 'θx', the process directly proceeds to a turning control of S10. When it is smaller than the normal hoisting angle 'θx', raising of the expansion boom is performed so as to prevent interference between the expansion boom and a control box in the case where the expansion boom is turned (S7). At the time when the boom hoisting angle becomes larger than the normal hoisting angle 'θx', the raising of the expansion boom is stopped (S8, S9), and the process proceeds to S10.

Inventor: KIKUCHI KIYOAKI
IPC: H01C13/02
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To provide a module resistor which hardly cracks and is capable of mounting many resistance elements. SOLUTION: A module resistor 5 consists of a disk-type ceramic board 6, resistance elements 7 radially arranged on the ceramic board 6, a common electrode 8 arranged at the center, and electrodes 9 of the respective resistance elements 7.
