Title: Ear microphone
Inventor: MOTOI KATSUO
IPC: H04R1/00
Filed: 1987-12-29
Abstract: PURPOSE:To prevent mis-operation of state changeover from reception into transmission unexpectedly or to avoid unpleasant sound from being given to an opposite party due to occurrence howling by a converting element caused by sound pressure energy by communicating a space formed between a front face of an inserting body and an eardrum to an external part via a duct. CONSTITUTION:A duct 15 connected between an outer skin and a front face of an insertion body 1 is formed. That is, the duct 15 is formed by a slot 1e, holes 7a, 8b, 14a and the front face of a sound opening 1d is communicated to an external part by the duct 15 via the outer skin 14. The enclosed space between the sound opening 1d of the inserting body 1 and the eardrum caused by the loading of the inserting body 1 into the ear by the user is communicated externally through the duct 15. When the sound pressure in the space is increased by the sound guide pipe 3, it is escaped through the duct 15 to keep the pressure in the space to a prescribed value or below. Thus, no sound from the sound guide pipe 3 is propagated to the conversion element 5 and occurrence of howling is prevented.

Filed: 1993-12-28
Abstract: PURPOSE:To evade the disabled state of locus control to which deviation feedback is added as much as possible by selecting arms whose rotation direction is not a stroke end and outputting constraint conditions corresponding to the selected two arms. CONSTITUTION:In an articulated work machine, in the case of selecting the arm on a correction direction side whose moving amount becomes maximum in a correction direction and minimum in a work direction, a constraint condition selection means 300 selects the arm on the correction direction side for which either one of the rotation directions is not the stroke end and inputs the constraint conditions to respective velocity computing means 400. A correction direction velocity command value computing means 600 computes a correction direction velocity command value corresponding to a deviation between a locus control object part and a target locus and the correction direction velocity command value and a work direction velocity command value are inputted to an angular velocity computing means 400. Then, the arithmetic result is inputted to a control means 500 and a pair of the arms are driven by a computed angular velocity. Thus, the control is not disabled during deviation feedback control.

Title: Magnetic head crush preventing device for magneto-optical disk device
Inventor: DATE KOICHI
IPC: G11B11/10
Filed: 1989-12-25
Abstract: PURPOSE:To prevent a magnetic head from crushing by providing a means which switches the focus servo system of a 2nd optical system to the focus servo system of a 1st optical system when a focus error signal exceeds a specific range and the output sum of a photodetector approximates zero. CONSTITUTION:The magnetic head 4 is displaced to the lens 5 of the 2nd optical system associatively. When the focus error signal obtained from the output of the photodetector 15 of the optical system 2 exceeds the specific range and the output sum of the photodetector 15 approximates zero, the focus servo system of the optical system 2 is switched to the focus servo system of the 1st optical system 1. Thus, if the 2nd optical system enters an out-of-focus state for some reason, the servo system is switched to the servo system of the 1st optical system instantaneously, so the magnetic head is prevented from crushing.

IPC: G11B17/028
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To clamp a disk by a minimum necessary clamping force when attaching/detaching a disk, and by a large clamping force when rotating the disk, since simultaneous achievement of the high-speed rotation of the disk and the easy unclamping of the disk is difficult when disk clamping performed by the magnetic attraction force of a permanent magnet acting between a chucking pulley and a turntable for holding the disk therebetween.

During a high-speed disk rotation, the disk is strongly clamped by a magnetic force and the clampers 21 and 22, and during unclamping, the clamping is released by weak power countering the clamping force corresponding to a weak magnetic force. Thus, both are simultaneously achieved.
