Title: Composite mesh structured sheet with antislipping function
Inventor: HIYOSHI TAKEO
IPC: A47C27/00
Filed: 1999-10-26
Abstract: PROBLEM TO BE SOLVED: To provide a composite mesh structured sheet with an antislipping function which absorbs the sideways movement of a human body, reducing a sense of being rubbed despite its antislipping function, and which has a good cushioning property. SOLUTION: A composite mesh structured sheet consists of upper and lower meshes and an interposing panel layer made of countless fibers connecting the knitting threads of these meshes. To a lower face of this sheet, a flexible antislipping sheet having an air-permeability and formed on its rear face with a rubber foaming material serving as an antislipping function is pasted. Due to this structure, the antislipping function can be effectively exerted. In disregard of its antislipping function, this sheet absorbs the sideways movement of a human body, reducing a sense of being rubbed. This sheet can be used as a comfortable bed mat, seat mat or the like due to its good cushioning property, air-permeability, and pressure distributing propery.

Title: Electron cyclotron resonance plasma cvd device
Inventor: KAMIYAMA MICHIYA
IPC: C23C16/511
Filed: 1989-11-22
Abstract: PURPOSE:To uniformize the density of plasma flowing into a reaction chamber and to simultaneously attain the uniformity in film thickness and homogeneity by providing an impeller to be rotated by a plasma current in the plasma current. CONSTITUTION:A rotating stirrer 12 as the impeller is set between a plasma producing chamber 10 and the reaction chamber 30 in the electron cyclotron resonance plasma CVD device. The plasma current proceeding to the reaction chamber 30 from the plasma producing chamber 10 collides with the blade 12b of the stirrer 12 to rotate the stirrer 12, and agitated by the rotation. The density distribution of the plasma introduced into the reaction chamber 30 is uniformized by the agitation. Since the opening 12a of the stirrer 12 is rotated and moved by the rotation of the stirrer 12, the plasma current is not shadowed, and the uniformity in the film quality is unaffected.

Title: Grommet
Inventor: MAKABE TORU
IPC: H01B17/58
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To reduce the pushing force at the time of fitting, and to prevent the lowering of the holding force after the fitting by lightening a grommet main body from the inner surface side of a circumferential wall thereof so as to form recessed parts, which are directed from one end to the other end in the radial direction around a center shaft. SOLUTION: A hollow truncated cone-shaped grommet main body 2, which is formed thick, is formed with an annular groove 4 having the recessed-shaped cross section, which is to be fitted in a panel hole of a partitioning wall of a vehicle or the like, in the outer peripheral surface of the main body 2. The main body 2 is formed with four recessed parts 7 by lightening the main body 2 from the inner surface side 2b of the circumferential wall. Each recessed part 7 is formed into the same shape, and radially arranged in relation to the center shaft of the main body 2 with an equal space in the inner surface side 2b of the circumferential wall. With this structure, since a flexible part 2a is formed with a thin part, at the time of fitting the groove 4 in the panel hole, the main body 2 can be bent by the force smaller than the conventional case.  At the time of fitting, since the thin parts are bent opposite to each other and the thick part is not bent, the main body 2 can be easily bent. Consequently, lowering of the holding force of the main body 2a in relation to the panel hole can be prevented.

Title: Inching feed control apparatus of ultrasonic probe
Inventor: SHIRAISHI MASAAKI
IPC: G01N29/26
Filed: 1988-12-02
Abstract: PURPOSE:To control inching feed by operating a connected probe by synthesizing the difference signal of the data of the position of the probe with respect to a desired inching feed position, the speed data signal of the operated probe and a data signal for stopping the probe at a desired position to amplifying the same and supplying the amplified signals to a motor driving circuit. CONSTITUTION:The output signal of the difference between the data of a desired inching feed position and the position data of a probe is amplified to be supplied to a probe driving motor 11 to operate a motor. On the basis of positive and negative speed data signals at the time of operation, data of one polarity is selected corresponding to the rotary direction of the motor to feed back an output signal and the probe 13 connected to the driving motor is operated at a constant speed with respect to the load variation of the driving motor. When the probe reaches before + or - count based on a digital output value with respect to a desired inching feed position, the output signal due to the data of one polarity of a brake data signal divided into positive and negative polarities corresponding to the rotary direction of the driving motor is added to stop the probe at a desired position rapidly with good accuracy.

Title: Filed effect transistor logic circuit
Inventor: MAETA TADASHI
IPC: H03K19/0952
Filed: 1990-11-13
Abstract: PURPOSE:To reduce dispersion in a delay time due to temperature fluctuation by obtaining a gate bias of a buffer section current source FET from a reference voltage generating circuit. CONSTITUTION:A gate voltage of a current source FET 5 of a buffer section is obtained from a reference voltage generating circuit comprising a FET 7. When an H level is inputted to an input terminal 10, a level of a node 11 goes to an L level, a drive capability of a FET 3 is tentatively reduced and a load capacitor connecting to an output terminal 20 is discharged through the FET 5. The current in this case is decided by a gate bias of the FET 5. The gate bias is obtained from a reference voltage generating circuit and the level ismaximized at a threshold voltage decided by the parameter of the circuit. The current fluctuation of the current source FET caused by threshold level fluctuation due to temperature fluctuation is suppressed small by setting the design value of the threshold voltage to this value. As a result, the delay time of the circuit is immune to the effect of temperature fluctuation.
