Title: Both hand operating switch
Inventor: HIROSE YASUNORI
IPC: B30B15/00
Filed: 1992-02-07
Abstract: PURPOSE:To improve safety of a both hand operating switch used for a press device, etc. CONSTITUTION:A resistance value decision circuit 5 monitors the resistance value between the push buttons 1a and 1b through the contact 3a, 3b. When the resistance value between 1a and 1b is low, it is judged the push button was operated by both hand, closing a switch 6. At this time a drive signal is transferred to a drive circuit 7 through switch 4a, 4b. When a foreign matter pushes at least one of either 1a or 1b, the resistance value remains high maintaining the switch 6 open. Accordingly, the system is driven only at the time of both hand operation to secure an operator's safety.

Abstract: PURPOSE:To obtain a jitter correcting means leading to low cost and high performance by using an oscillated frequency of a VCO so as to modulate a high frequency portion of a reproduced luminance signal and providing nearly same jitter component as that of the reproduced luminance signal to the oscillated frequency of the VCO. CONSTITUTION:An FM luminance signal reproduced from a head 3 is amplified by a preamplifier 4 and the frequency is corrected by a peaking circuit 5. After the high frequency of an output of the peaking circuit 5 is converted at a high frequency converting circuit 11, one frequency is extracted by a BPF12 and demodulated by a demodulation circuit 6. On the other hand, a horizontal synchronizing signal (h) separated from the luminance signal by a synchronizing separator circuit 9 is compared for the phase with a reference signal hr at a phase comparator 15 and its output (v) is fed to the VCO17 via an LPF16. As a result, an output of the VCO17 has nearly the same jitter component as the reproduced luminance signal and the reproduced luminance signal is subject to high frequency conversion by a high frequency converting circuit 11 based on the signal, then the luminance signal suppressed with jitter component is obtained.

Title: Range hood
Inventor: MURATA YUKITAKA
IPC: F24F7/06
Filed: 1995-02-13
Abstract: PURPOSE: To facilitate a fixing or a removal of a range hood filter and its cleaning as well by a method wherein a filter-fixing fitting is arranged outside a suction port of a range hood main body formed in a slant shape and the filter is removably fixed to an outside part of the suction port by utilizing this fixing fitting. CONSTITUTION: In the case that a filter 14 is fixed to a suction port 11, the filter is fixed by inserting it against a fixing fitting 13 from an upper part or a lower part. When the filter is inserted from above into the fixing fitting 13, a claw 15 is hooked with the fixing fitting 13 to prevent from being disengaged in a downward direction. The filter 14 is formed to be larger than the suction port 11 in order to prevent a short pass f from around it. With such an arrangement as above, stain is hardly adhered to the filter fixing part and in the case that the filter fixing part is stained, it is possible to remove the filter to perform its cleaning in a quite easy manner or to replace the filter with a new one.

Title: Disk cartridge and disk device using the same
Inventor: FUKAGAWA YOSHIHIRO
IPC: G11B23/03
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To easily discriminate history of changing disks and to properly perform the maintenance and management by forming a cartridge with a sealing piece for sealing a lock mechanism part of an opening and closing member and making a lock mechanism incapable of unlocking unless the sealing piece is excluded. SOLUTION: Since the sealing piece 1b of the cartridge 1 is thinner than a lower case 4 in thickness, when this piece is pushed in or pulled out by using a pen point or the tip of a screw driver, etc., stress is concentrated in a connecting part between the sealing piece 1b and the lower case 4 so that the piece is easily breakable. Since the sealing piece 1b is formed out of plastic, etc., having elasticity, when this piece pushed in, the piece is elastically deformed, and its restraint by a hole 1a is released, and then from this state, an opening and closing lid 5 can be drawn out. From this state, the disk 2 is changed for another disk, which is then inserted into the inside of the cartridge 1, and the lid 5 is closed until the restraining piece 5b is locked by the hole 1a to be restored to their original state, thereby completing the disk change.
