Title: Vessel with hydrogen-occluded alloy molding housed therein and method of housing the same
Inventor: NISHIMURA KOICHI
IPC: C01B3/00
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To prevent hydrogen gas flow into the subject molding from lowering by securing the flow channel of hydrogen gas to the molding housed in a vessel, to absorb the stress of the volume expansion of hydrogen-occluded alloy, and to raise the packing rate of the alloy in the vessel. SOLUTION: Plural hydrogen-occluded alloy moldings are put into a vessel, and hydrogen gas-permeable sheets 3 are sandwiched between these moldings 1. Each of the sheets 3 is placed in between the moldings 1 adjacent to each other from one end of the vessel 2 to the other end and thus made to communicate with both the inlet/outlet 21 for hydrogen gas. The sheet 3 is made of a porous material having buffering effect, thus enabling the stress developed by the volume expansion of the hydrogen-occluded alloy to be absorbed onto the sheets 3.

Title: Sputtering device
Inventor: YOKOYAMA MASAHIDE
IPC: C23C14/34
Filed: 1990-11-13
Abstract: PURPOSE:To control film thickness with high precision by forming an electrode into a roll shape incorporating a sputtering magnet, and steadily traveling a target synchronously with the electrode in a film target type sputtering device. CONSTITUTION:After a chamber 8 is highly vacuumized and exhausted by an ordinary method and gas is introduced thereinto, both a winding roll 5 and a roll-like main electrode 2 which incorporates a sputtering magnet 1 and a water cooling jacket part 12 are rotated by a driving system. Therefor, when a film target 3 is traveled and steadily traveled synchronously with the roll-like main electrode 2, electric power is supplied to the main electrode 2 from a power source 10 to generate discharge. A target 3 is sputtered and a shutter 7 is opened to form a thin film on a base plate 6. Thereby fluctuation of the thin film forming velocity and distribution of film thickness is almost eliminated, thus yield and productivity are enhanced.

Title: Propagation path estimator and mobile receiver using the same
Inventor: SATO SHINICHI
IPC: H04B1/10
Filed: 1994-12-13
Abstract: PURPOSE: To improve the accuracy of a propagation path estimation value by suppressing a noise without using a time average at the time of finding out the estimation value. CONSTITUTION: This propagation path estimator is constituted of a 1st correlator 13a for outputting a complex correlation signal (β.exp (jϕ)+N2) defined by the correlation values of a 2nd diffusion code sequency with the in-phase component and orthogonal component of a received base band respectively as a real number part and an imarginary number part and a low pass filter 13b to which the complex correlation signal is inputted.  Since the frequency characteristics of amplitude β and a phase in a propagartion path estimation value (β.exp(jϕ)) are suppressed by maximum Doppler frequency and the frequency band of a noise (N2) is higher than the estimation value, the complex correlation signal is inputted to the low pass filter 13b having the frequency characteristic of fixed delay at the fixed amplitude up to the maximum Doppler frequency to remove or suppress the noie (N2) without exerting influence upon the characteristics of the propagation path. Consequently an accurate propagation path estimation value can be obtained.

Title: Screen
Inventor: FUKUHARA SUEAKI
IPC: G03B21/60
Filed: 1990-11-14
Abstract: PURPOSE:To improve acoustic permeability by using textiles obtained by overlapping an almost white textile having gas permeability and an almost black textile as constitutional materials, and setting the surface of the almost white textile to a projecting surface. CONSTITUTION:The textiles which are obtained by overlapping the almost white textile 1a having the gas permeability and the almost black textile 1b are used as the constitutional materials, and the surface of the almost white textile 1a is set to the projecting surface (d). Consequently, a sound wave 8 from a speaker 2 installed on the back side of a screen 1 reaches an audience after the sound wave is transmitted through the screen 1 without generating the deterioration of the characteristic. Mean while, projection light 9 projected on the screen 1 is reflected on the surface of the screen 1 in a good state, and some parts of light 9a and 9b reach the back side after they are transmitted through the screen 1, and they are reflected on a wall surface 7, etc., and then, they reach the surface of the screen 1 again, but the light can be prevented from coming out to the audience side in this case because the light is shielded by the almost black textile 1b. Thus, the acoustic transmissivity can be im proved, and also the screen excellent to visual performance such as contrast, etc., can be obtained.

Title: Controller for high frequency high voltage power supply
Inventor: UEDA TAKEHIKO
IPC: H02M7/48
Filed: 1992-10-26
Abstract: PURPOSE:To allow continuous regulation of output power from a high frequency inverter while eliminating switching loss. CONSTITUTION:A current detecting means detects resonance current flowing through the resonance circuit in a high frequency high voltage power supply and a PLL circuit 15 locks the frequency at a level for matching the phase with the resonance current thus obtaining synchronized pulse. A PDM circuit 16 forms a zero voltage output interval of a set length for the pulse thus obtained and regulates output power by modifying the pattern of the gate signal for the semiconductor switching element in a high frequency inverter. Gate signal for the semiconductor switching element is generated such that the resonance circuit is short-circuited during zero output voltage interval thus operating the PLL circuit continuously.
