IPC: A47C20/04
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent or relieve the dropping of the waist when a user raises an upper half body by actuating the upper half body supporting frame to rise. SOLUTION: A lower half body mattress 4 fixed to a lower half body supporting frame 2 and an upper half body mattress 5 fixed to the upper half body supporting frame 3 are separated from each other and the end 4a of the lower half body mattress 4 on the upper half body mattress 5 side deviates more to the head side than a virtual axial center O which is the center of rotation of the luffing operation of the upper half body supporting frame 3.

Title: Radio equipment
Inventor: ITO KAZUYUKI
IPC: H04B1/10
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To detect a dead channel signal even in a weak electric field and to avoid the dead channel signal from being outputted as noise by reading the dead channel signal by the portion of plural cycles and reading rising and falling of a signal together. SOLUTION: At the time of receiving the dead channel signal, a comparator 9 converts it into a digital signal. A CPU 7 detects the presence/absence of the dead channel signal by reading rising and falling of the portion of plural cycle periods (four cycles e.g.) concerning the converted digital signal. Thus, since the dead channel signal can be detected at the time of a dead channel even in the case of using the radio equipment in the weak electric field, it is possible to avoid unnecessarily generating noise. When the CPU 7 judges the dead channel signal to be undetected in spite of receiving the dead channel signal at this time, voltage is supplied for a tone squelch part 6 from the CPU 7 to interrupt a tone signal to interrupt voice output. When a signal does not pass through the comparator 9, a tone squelch is not interrupted.

Title: Scroll type machine with volume control mechanism
Inventor: MAAKU BASU
IPC: F04C28/08
Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To modulate continuous capacity from 100% full capacity to 0% of a scroll type machine by a single control mechanism. SOLUTION: Axial or radial relative movement between both scroll members 26, 32 is obtained to release sealing of a fluid pocket between both scroll blades to thereby obtain load release of a machine. Relative movement is accomplished by controlling fluid pressure in one chamber between two fluid pressure chambers 56, 58 by a solenoid valve 68 to move one scroll member 32 in one direction or the other direction or moving the scroll member by the other actuator. Capacity is modulated by making machine operation in a loaded state or load released state periodic. It is therefore recommended to use a sensor 82 for sensing the fluctuating condition of an air-conditioning system or the like, and a valve control module 80. In another embodiment, control mechanism is provided to improve motor efficiency during load release operation.

IPC: H04N1/40
Filed: 1990-11-15
Abstract: PURPOSE:To emphasize qualitative intermediate brightness by setting the inclination alpha of a picture converting processing line as tanalpha=W/(N-W). CONSTITUTION:An input part 1 inputs a starting level (gradation) L of intermediate brightness to be convert-processed and a W input part 2 inputs the width W of the intermediate brightness to be convert-processed. A calculating part 3 of tanalpha calculates the tangent of the inclination alpha of a converting processing line by tanalpha=W/(256-W). An input frequency input part 7 at each gradation inputs the generation frequency at each gradation (every 0 to 255) of an input picture. A picture converting processing part 8 selects a processing line corresponding to the respective gradation and executes frequency conversion by the selected processing line. An output picture output part 9 outputs the picture converted in such a manner.

Title: Wood supply method and apparatus in sawing machine
Inventor: MIYATA HIDEO
IPC: B27B31/02
Filed: 1988-12-08
Abstract: PURPOSE:To enhance working efficiency and to achieve the reduction of cost by presetting the sawing guide line position of the side part of wood on the lateral side of a wood insert route and transferring the wood positioned on the lateral side to a stopping means. CONSTITUTION:When both-edged wood having both sawn surfaces is supplied by a wood supply deck conveyor 11, the end edge of the wood is stopped by a preset stopper 21. In this state, the rods 15 of front and rear positioning bodies 12 are advanced and retracted to align the side edge part of the wood with the marker line (b) formed by a preset marker 10. When a chain lifter 26 and a wood feed lifter 25 are raised and tilted on the basis of a set completion signal, the wood is fed to the right while held to a definite posture to be stopped by a receiving stopper 18. When the lifter 26 is allowed to fall, the wood is placed on the lifter 25 and, when the lifter 25 is allowed to fall, the wood is placed on rollers 6a to be forcibly fed. Even when the side edge of the wood has unevenness, since the stopper 18 falls toward the outside to be retracted, the wood is straightly fed.

Title: Cleaning method of cvd sio2
Inventor: MORI ISAMU
IPC: H01L21/304
Filed: 1990-11-16
Abstract: PURPOSE:To clean SiO2 simply and without damaging a thin-film formation apparatus by a method wherein the SiO2 which has been deposited inside the apparatus is cleaned within a specific temperature range by using a chlorine fluoride which contains at least one kind out of ClF, ClF3 and ClF5. CONSTITUTION:SiO2 which has been deposited inside a thin-film formation apparatus is cleaned within a temperature range of 400 to 800 deg.C by using a chlorine fluoride which contains at least one kind out of ClF, ClF3 and ClF5. Consequently, the silica produced by a reaction is amorphous, its film itself does not form a network of Si-O-Si-O- completely, one part of it contains carbon, a bond such as Si-H, Si-O-H or the like is left and its density is low as compared with quartz glass. As a result, it is easily attacked by the chlorine fluoride. As a result, it can be dissolved at a low temperature as compared with the quartz glass. Thereby, it can be cleaned simply and without damaging the apparatus.

Title: Purification of higher fatty acid, higher alcohol and aromatic compound
Inventor: HIRAYAMA CHUICHI
IPC: C07C31/125
Filed: 1993-11-05
Abstract: PURPOSE:To purify higher fatty acids, higher alcohols and aromatic compounds without using an aromatic non-polar phase by using a filler for reversed phase chromatography capable of recognizing the shape and length of a molecule. CONSTITUTION:The purification of the above compounds is carried out by a liquid chromatography using a filler obtained by bonding a polymer of the formula ((n) is 2-200; R1 is Hor methyl; R2 contains (CH2)mCH3; (m) is 3-21; X is functional group such as propyltrimethoxysilyl; Y is residue such as H) through the terminal X group to a silica gel. This process enables the separation and analysis of higher fatty acids, separation and analysis of higher alcohols and separation and analysis of condensed polycyclic hydrocarbons. Since the supported non-polar phase is free from aromaticity, it does not exhibit unfavorable PI-PI interaction with solute molecules. Since the supported non-polar phase is a polymer bonded to silica gel through one terminal, it has flexibility, changes the molecular orientation with temperature and enables the control of the holding time of solute and the shortening of the analysis time by controlling the temperature.
