Patent JP-H0410800-A (JP)
Title: Diaphragm for electroacoustic transducer
Inventor: ONO YUJI
IPC: H04R7/02
Filed: 1990-04-27
Abstract: PURPOSE:To improve the rigidity of a diaphragm without lossing the characteristics of cellulose fibers by using fine cellulosic fibers extracted from the sheath of sea squirt. CONSTITUTION:A sheet consisting of only the fine cellulosic fibers extracted from the sheath of sea squirt is used. although a cellulose material with high crystallinity is preferable as a cellulosic fine fiber material as compared with a high rigid fiber, the cellulose of sea squirt (tunicin) is proper as a starting material because its crystallinity is higher than other natural cellulose. Consequently, the electroacoustic converter diaphragm having high rigidity, improved at its airtightness and reduced at its air leakage can be obtained.

Filed: 1983-06-21
Abstract: PURPOSE:To reduce man-hours and remove the positional displacement of a window, and to obtain desired breakdown characteristics by reutilizing the window for the first selective diffusion for the second selective diffusion. CONSTITUTION:A window 6 is bored to an SiO2 film 5 on a P<-> type Si substrate 4, and P is diffused to form an N<-> layer 2. An SiO2 thin-film 8 as the surface is removed by fluoric acid, B is diffused from the window 6 again, the time for diffusion is adjusted properly, and P-layer 3 is formed in the same shape as the N<-> layer and depth shallower than the N<-> layer. A positional displacement is not generated in the P-layer 3, and it has uniform thickness. Ti 9 is applied, a bump electrode 10 is superposed through Ag plating, and an ohmic electrode 11 is attached on the back of the substrate 4. In the constitution, since the window is bored once, man-hours are decreased, the window is not displaced, the layer 2 having uniform thickness is obtained, and thickness can be controlled accurately by setting the time for diffusion, thus acquiring desired breakdown voltage.

Title: Image transfer using elastic film
Inventor: MOGI MASAO
IPC: B41F17/34
Filed: 1990-04-27
Abstract: PURPOSE:To enable even a high definition image to be printed on a large area by transferring the image through a sheet-like elastic film. CONSTITUTION:An elastic film 1 is fixed by a support 2 on the both ends and maintained level, and a specified drawn line part 3a is formed on the surface of an intaglio plate 3 for printing which is filled with ink 4. A space between the elastic film 1 and the intaglio plate 3 is sealed to form an airtight chamber 5. In addition, an air inlet and outlet hole 5a is provided in a part of the chamber. Air is sucked through the hole 5a to decompress the pressure of the chamber 5. As a result, the elastic film 1 is curved downward to stick to the upper surface of the intaglio plate 3. Then if air is forced into the chamber through the hole, the elastic film 1 is restored to a level position, and the ink 4 of the drawn line part 3a of the intaglio plate 3 sticks to the lower surface of the elastic film 1 and thus is transferred. After this process, a material to be printed 6 is set to a position of the intaglio plate 3, and the pressure of the airtight chamber 5 is reduced again. This caused the elastic film 1 to be curved downward and comes in close contact with the surface of the material 6. Subsequently, the ink 4 is transferred to the surface of the material 6. Next, if air is sent into the chamber 5 through the hole 5a, the elastic film 1 is restored to a level position, and the drawn line part 3a of the intaglio plate 3 is transferred to the surface of the material 6.

Title: Method of forming threaded hole in thin-walled metallic formed product with closed section and fense post made by this method
Inventor: IZAWA KATSUHIKO
IPC: B23G1/16
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To form a threaded hole having a high fastening strength in a thin- walled metallic formed product with a closed section, provide a an inexpensive a thread fastening component or improve efficiency in fastening operation. SOLUTION: When a thin-walled metallic product having a closed sectional surface 3a is cold rolled, a detent groove 7 inclined to project into the closed sectional surface 3a is formed in advance at a flat part 3b formed at a part of it. A width of the detent groove 7 is larger than a diameter of a threaded hole 6 formed afterward, and then its central location is formed with a threaded hole. The number of threaded peak portions of the threaded holes 6 is substantially increased. When a bolt is threadably fitted to the hole, even if a pulling load is applied to it, the detent groove 7 is inclined in an opposite direction of the pulling direction, so that a deformation where a peripheral edge of the threaded hole 6 is apt to rise up is prevented as much as possible and then the threaded hole 6 may realize a high fastening force.  As compared with performing a burring work, the threaded hole formation is quite easily performed and the hole can be made in less-expensive manner.

Title: Bridged tap equalizer
Inventor: TSUDA TOSHITAKA
IPC: H04B3/04
Filed: 1983-06-23
Abstract: PURPOSE:To equalize at high stability in relatively short time by detecting arrival of a pulse signal at equalizer input and controlling an inhibition gate by output that delayed the detection pulse one step. CONSTITUTION:An equalizer output signal is delayed by plural steps of delay cicrcuits D1-D3 through an inhibition gate IHG. Delayed output of each step is multiplied by coefficients C1-C3 by multipliers M1-M3 respectively, and output of multipliers M1-M3 is subtracted from an input signal IN by an arithmetic circuit SM to obtain output of a bridged tap equalizer. When the input signal of the equalizer is pulselike form, this is delayed by the time 1T for a time slot by the circuit D1, and this is detected by a pulse detecting circuit PD. The detected pulse is waveform shaped by a time constant circuit TC, and a gate IHG is controlled by the signal, and the pulse to be inputted next is inhibited by IHG. Accordingly, no signal due to secondary echo occurs, and action is controlled at high speed.

Abstract: PURPOSE:To increase the detecting capability of focus for all objects, by stressing and extracting the characteristics of the object while maintaining the same in the stage of binary encoding a picture image while maintaining the rough part thereof. CONSTITUTION:The luminous flux from near A of a luminous flux for detecting focus, more particularly, an afocal system 1 forms the optical image of an object on the left side of an image sensor CCD 7, and the luminous flux from near B forms the optical image of the object on the right side. The two optical images on the CCD 7 are converted to time serial image signals which are inputted to a binary encoder 9, and are separated to the image signals from the luminous flux A and the luminous flux B by the two registers contained in a correlator 10. The two separated image signals are inputted with the degree of the coincidence with each other as a correlation signal to an arithmetic circuit 11, by which the rate of deviation from a reference value is calculated. The focus is automatically adjusted with a driving circuit 12. Then, the detecting capability of focus for all objects is increased.
