Patent JP-S60138855-A (JP)
Title: Fuel cell
Inventor: OGAWA HAKARU
IPC: H01M8/04
Filed: 1983-12-27
Abstract: PURPOSE:To conduct heat conducted from a fuel cell main body to a porous body to reaction gas by using the porous body as a heat exchanger by installing a porous body which rectifies a reaction gas. CONSTITUTION:A porous body is used as a rectifier 20. Since the porous body has a large surface area, its contact area with gas becomes large. Reaction gas can effectively be heated by using heat conducted from a fuel cell main body to the rectifier 20. An electrical heater 21 is installed in the rectifier 20 and the fuel cell main body 1 is uniformly heated in a short time at starting by using the electrical heater 21. Since the electrical heater 21 and the rectifier 20 are accommodated in manifolded main bodies 15a and 15c, heat loss for temperature increasing is remarkably decreased.

Title: Overload control method of sound signal level
Inventor: MURANO KAZUO
IPC: H04M3/56
Filed: 1983-12-27
Abstract: PURPOSE:To compress simply and quickly the level of an overloaded sound signal by shifting only the bit string constituting the component of the sound signal exceeding a prescribed overload level to the lowest bit direction by a prescribed number of bits. CONSTITUTION:The sound signals added sequentially and digitally are supplied to the 1st accumulator 51 and stored there. The overload control is not needed before a sound signal level Pout reaches an overload level P0. Therefore the contents of bits A1-A4 and L of the low-order bit strings are shifted to the bits B1-B4 and L of the 2nd accumulator 52 via a selector 53 and sent onto a circuit. While the selector 43 works when the level Pout exceeds the level P0. The data are shifted as S B1, A1 B2, A2 B3, A3 B4 and A4 L, where S means the polarity bit of a high-order bit. An overload detecting part 54 detects whether the level Pour exceeds the level P0.

Filed: 1993-09-30
Abstract: PURPOSE:To provide an FM signal digitizing circuit which can improve the processing precision of FM demodulation or the like by reducing a quantizing error contained in a digital FM signal. CONSTITUTION:An analog FM signal is amplified by a variable gain amplifier 14 corresponding to an amplitude control signal, inputted to an A/D converter 3 after the output amplitude is limited by a limiter 16 and a higher harmonic wave component generated due to the amplitude limitation is removed by an LPF 17 later, and converted into the digital signal. Then, the amplitude level of the converted digital FM signal is detected by an amplitude detection circuit 15, the error concerning the detected amplitude level is calculated by calculating the difference from a specified level at a subtracter 11, and an amplitude control signal for correcting this error is generated by an integrator 12 and a D/A converter 13 and transmitted to the variable gain amplifier 14.

IPC: F16K1/226
Filed: 1987-09-29
Abstract: PURPOSE:To improve controllability of a valve provided with the flow characteristic approaching the linear characteristic by changing a mountain-shaped seat part in its radius, width and internal diameter and setting a valve unit peripheral edge in its bite-in amount and bite-in moving distance into a seat so as to be equal in the valve unit peripheral edge in its arbitrary position. CONSTITUTION:A seat ring 16, adapted to a valve unit 11 when it is closed, is constituted of the first and second mountain-shaped seat parts. The first mountain-shaped part changes its radius R, width W and internal diameter X4, setting a valve unit peripheral wedge in its bite-in amount (t) and bite-in moving distance E into the seat ring 16 so as to be equal in the valve unit in its arbitrary peripheral edge. While the second mountain-shaped seat part, to which the point end edge surface of the valve 11 is forced to be adapted decreasing the bite-in moving distance, is formed in the vicinity of a boss part 12. Thus eliminating an unnecessary bite-in amount, valve shaft torque decreases its change. While obtaining about 10-20 deg. fully closed seal position, the opening- flow amount characteristic approaches the linear.

Title: Wadding
Inventor: AIYAMA KAZUNORI
IPC: D04H1/02
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To provide wadding having sufficient water absorptive and hygroscope properties and sufficient durability, elasticity and comfortablenes by forming chairs, bedding, etc., provided with layers having at least the water absorptive and hygroscopic properties and integrally bonding another layer with the sheet layer which softens and has the surface temp. lowering by more than a specific temp. than the ambient temp. SOLUTION: A water resistant film is preferably bonded to one surface of the water absorptive and hygroscopic sheet. The water resistant film having a function to allow the permeation of steam but not to allow the permeation of liquid is more preferable. For example, microporous films, etc., of polyurethane and polyethylene are preferably used. When the film absorbs moisture, the moisture begins to evaporate as steam and, therefore, the film is thereby deprived of the latent heat of evaporation. The film of which the surface temp. falls preferably by >=2 deg.C, further preferably >=3 deg.C, after 30 minutes by absorbing the moisture of at least 0.5 times the weight ratio of the water absorptive and hygroscopic layer is preferably used.  Such falling temp. preferably falls largely in an early time and is determined by a moisture releasing rate and, therefore, the stock of a cellulose system is preferably used.

Title: Temperature control of die
Inventor: NOZAKI MIKINARI
IPC: B22D17/22
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To improve productivity by solving the crack of a die due to the thermal stress and also minimizing the shot number required for sacrifice pressing. SOLUTION: In the case where the temperature of a die 1 is lower than the proper temperature area such as at the time of starting a casting operation and the like, a cooling water is supplied to a cooling water path 2 installed in the die 1 under the condition that a switch valve 7 provided to a drainage path 5 is closed. Thereby, pressure of the cooling water in the cooling water path 2 is raised, for rising the boiling point of the cooling water. When waste punching is carried out under this condition, the water (compressed water) of higher temperature can be formed without evaporating the cooling water in the cooling water path 2, so that temperature rising of the die 1 due to the heat received from the molten metal can be promptly achieved. Thus, the number of shots required for waste punching is reduced for improving productivity.  Furthermore, since the waste punching is carried out while the cooling water is supplied to the cooling water path 2, problems of cracking of the die 1 due to the thermal stress can be solved.
