Title: Pulse wave detecting device
Inventor: ITO MASAHIKO
IPC: A61B5/0245
Filed: 1988-11-30
Abstract: PURPOSE:To ensure the proper detection of a pulse wave with freedom from a contact resistance change between a skin and an electrode by operating a difference between the first and second impedance signals with an operation means for generating the difference as an impedance difference signal, and taking out a pulse wave component during body motion on the basis of the impedance difference signal. CONSTITUTION:When electrodes 20a to 20d as mounted on the surface of the skin of a living body 10 are made to operate, each of oscillators 30 and 40 generates a respective oscillation signal. Then, an adder circuit 50 adds each oscillation signal and generates an addition signal, while a constant current circuit 60 causes a flow of a constant weak current to the living body 10 via both electrodes 20a and 20b, depending upon the addition signal. A wave detecting signal from wave detectors 100a and 100b contains a noise component and a pulse wave component corresponding to the predetermined frequency during the motion of the living body 10. The device in the title, however, is so made that each noise component in both wave detection signals during every body motion is identical, and the phases of both wave detecting signals agree to each other under the delayed operation of a delay circuit 110. According to the aforesaid construction, it is possible to accurately display a pulse wave even during the motion of the living body 10 without any adverse effect by a noise.

Abstract: PURPOSE:To securely feed a tape one by one and obtain a tape feeder performing smoothly a bundling work, by providing a peeling off roller shifting the uppermost tape to the feed direction while a pressing piece is kept from the tape face prior to the feed of tape with the feed roller. CONSTITUTION:When a tape cassette 11 is inserted into an appropriate position of a guide groove 2 and a peeling off roller 31 is rotated in the pressed condit ion of a tape 12 laminated within the tape cassette with a feed roller 21, the rear side of the tape feed roller is transferred, pulled by the peeling off roller but the feed roller is not rotating and hence, this tape is kept from the other tape swelled and laminated between the feed roller and the peeling off roller and the rear end of the tape is shifted from the position of press piece 41. Next, when after the press piece pushes the upper face of the rest of tapes the feed roller is rotated, only the uppermost tape separated is fed to the front end of the guide groove.

Title: Depilator
Inventor: OGAWA HITOSHI
IPC: A45D26/00
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To prevent the damage of a driving transmission part as against pinching hair and engaging a foreign matter and also to make a depilating driving part and a head part small by arranging an over-load clutch in a driving transmission system between the depilating means for pulling-out hair and a motor being a driving source. SOLUTION: In a leaf spring 132 constituting the over-load clutch, arm pieces 132a come out from the plural places of the spring in the opposite direction of the rotation one, each support part 132b is disposed at the tip part of each arm piece 132a and also a positioning hole 132c and a screw insertion hole 132d are arranged. In case driving power being more than a set prescribed torque is transmitted, the support part 132d disposed in each leaf spring 132 comes off a lock part 131b, a large gear 131 skids as against a small gear 130 and driving power is not transmitted. Therefore, the driving transmission part is prevented from being damaged since the torque of the motor is interrupted in case of locking owing to pinching hair between gears or engaging the foreign matter.

Title: Printing system
Inventor: SOEJIMA YASUSHI
IPC: G06F3/12
Filed: 1990-11-13
Abstract: PURPOSE:To obtain diverse print results without judging application software for printing by accepting a character font registration request from a printer side by a character font detecting and informing means and registering a character font by a dynamic character font registering means at need. CONSTITUTION:If a character font needs to be changed during printing operation and the character font is not loaded in advance, the character font detection and information part 2 detects the information and sends the character font registration request to the dynamic character font registration part 3. Then the character font registration part 3 sends character font data to printer 4 from character font data 1 at the request and the printer 4 once receiving the data starts printing operation. Consequently, the number of usable character fonts for each job output unit becomes substantially infinite. Consequently, diverse print results can be obtained without judging the application software for the printing.

IPC: H03K5/1536
Filed: 1993-12-06
Abstract: PURPOSE: To improve zero crossing precision by reducing an asynchronous sampling rate, and to reduce the bit error ratio of a recording channel by exactly detecting the threshold crossing of a series of digital samples. CONSTITUTION: In a waveform preprocessor 22, a signal differentiator 46 differentiates a data signal waveform 20, and converts the peak of the waveform into zero crossing transition by a conventional valid method. When a medium 12 is constituted of the magnetic tape of a tape drive 48 or the magnetic disk face of a direct access storage device(DASD) 50, restored data are allowed to appear as a peak or pulse in the waveform 20. The differentiation in the signal differentiator 46 is necessary for the detection of the pulse. When the medium is an optical medium in an optical disk 52, the signal is PWN-processed, and the restored data are coding-processed through a variable and prescribed threshold as waveform transition.
