Title: Compound-system speaker
Inventor: ANDOU OUTAROU
IPC: H04R23/02
Filed: 1978-11-07
Abstract: PURPOSE:To obtain a speaker which features a high efficiency and is capable of reproduction for a sufficiently low sound by combining quite different principles of the dynamic and piezoelectric types. CONSTITUTION:Coil conductor layer 10 functioning as a plane coil as well as an electrode layer is provided on one surface of high molecular piezoelectric film 8, along with full-surface electrode layer 9 provided on the other surface each. Thus vibrating film 7 is formed to be stretched out via frame 11. Then bar magnet 12 and magnetic plate are distributed in opposition to each other and holding film 7 between, thus forming magnetic circuit. The aural current is flown to coil conductor 10 from the low-impedance signal source to secure the operation as a full-surface driving type dynamic speaker. At the same time, the full-wave rectified aural signal is applied between conductor 10 and layer 9 so that film 7 may extend according to the absolute value of the aural signal. Furthermore, resistance 25 satisfying a fixed conditions is connected in parallel to the area between layer 9 and the coil conductor layer. In such constitution, a high-efficiency reproduction is possible for the low sound.

Title: Fuel cell type power generating apparatus
Inventor: DOI KUNIHIRO
IPC: H01M8/06
Filed: 1992-05-28
Abstract: PURPOSE:To provide a fuel cell-based electricity generating apparatus which can recover a sufficient amount of steam from a fuel cell side, suppress the shortening of the life of a catalyst of a carbon monoxide converter, and is made small in size and compact. CONSTITUTION:To carry out conversion treatment of a gas in an outlet of a reformer, pressured water taken out of a high temperature water line for exhaust heat recovery in an apparatus is sprayed to a conversion catalyst packed layer 4 side through a spray nozzle 5a in a carbon monoxide converter 3. In this case, the flow rate of the pressurized water is adjusted by a controlling apparatus 22 which controls the flow rate adjusting valve 21 corresponding to the electricity generation load. Consequently, the pressured water is easily evaporated even if it is sprayed and the conversion catalyst packed layer 4 is prevented from being wet. Also, since it is no need to cool a reformer outlet gas in the outlet of the carbon monoxide converter 3 to obtain condensed water for spraying, the recovery amount of the steam in the fuel cell 10 side increases and the apparatus can be made compact and small in size.

In the case of detecting tension, a section L is brought into contact vertically with the probe 4 from above or below, and the contact 8 is displaced by the reaction force vertically against the energization force of the spring 6. Each position detector 7 detects a displacement position, and outputs a signal through the contact 8 when the section L has reached a displacement position corresponding to a specific bend angle θ, and a display 10 displays tension only when the section L retains the angle θ.

A judging means judges the positional dislocation of the driven body at this start of reopening of current application, to the study position of the driven body in the initial number of steps at the last break of current application.  A control means 50 controls the driven body into the reference position and makes it execute the initial check, prior to driving the step motor 20, based on the objective number of steps, when the positional dislocation is judged by the judging means.

CONSTITUTION:A contact opening 15 is provided with a photoresist film 6 serving as a mask in an oxide film 3 on a silicon substrate 1 provided with a diffusion region 2. A process follows wherein lift-off is accomplished for the removal of a platinum film 7 and the photoresist film 6 with a fractional platinum layer 7a retained on the bottom of the contact opening 5. The entire source is covered by a 0.2-0.3mu-thick silicon film 8 and then arsenic ions are implanted. Next, heat treatment is performed at a temperature of 700-800 deg.C to trigger off silicide-forming reaction. Finally, a flattened electrode is built, after the silicon film 8 left unaffected on the oxide film 3 is removed, with the contact opening 5 filled up with platinum silicide 9. With the contact opening 5 being filled up with platinum silicide 9, an aluminum wiring is completely protected from disconnected due to improper, stepped coverage.

An objective primary side turning sped is calculated from a relationship between the value induced from the above and an outputted turning speed corresponding to the running speed of a car, and the obtained value is divided by an outputted turning speed every moment so as to calculate the objective value of a transmitting ratio in a stable state. Further, a secondary oil regulating value 11 is controlled corresponding to the detected result about transmitting torque of the CVT 8.  Then, deviation from an objective sped changing ratio is multiplied by a predetermined gain, the obtained value therefrom is divided by a variable corresponding to a secondary pressure of the CVT 8 and integrated, and a resultant value is multiplied by a variable to be outputted.

Title: Binary processing method for analog picture signal
Inventor: YUASA KAZUHIRO
IPC: H04N1/405
Filed: 1980-10-03
Abstract: PURPOSE: To obtain a binarized picture signal in which tonal recording is obtained at reproduction and recording, by storing a plurality of threshold level data to a storage device in advance.  
     CONSTITUTION: A plurality of threshold data are stored in an ROM, and one set of data are specified by switches SW1, SW2. The data give a tone to a binary picture signal from a picture reader ISV. That is, the ROM gives an analog signal indicated (x), (y) of the data set based on the value of counters COx, COy to a comparator CPA as a reference voltage Vref. On the other hand, an analog signal of a picture original picture element is applied to the CPA, and the binary signal of the picture original picture element is outputted from the CPA. Thus, the binary picture signal is the same as the case when an analog picture signal read in by superimposing a lattice shaped contrast pattern on the picture is binarized with a prescribed level threshold, allowing to obtain recording intermediate tone.

Title: X-ray transmitting film

IPC: H05G1/02
Filed: 1991-05-14
Abstract: PURPOSE:To provide a film with a large area, high X-ray permeability, and improved strength, hardness and pressure resistance by providing a hard carbon film on one or both faces of the polymer material film. CONSTITUTION:Polyester or polyimide is used for the raw material of a polymer film. A hard carbon film is formed on one or both faces of the film face, however if the carbon film is formed on both faces, the film is rarely curled and easily used. The hard carbon film is the so-called amorphous diamond-like carbon film. The hard carbon film is formed from the hydrocarbon gas in the process that a film forming active species is generated by the plasma method with DC, AC or microwaves through the plasma state. The raw material gas is decomposed into radicals and ions and reacted in the plasma state, thus the hard carbon film containing at least one of amorphous and fine crystals made of carbon atoms and hydrogen atoms is accumulated on a substrate.
