Title: Waste heat recovery device
Inventor: OOSHITA KAZUYOSHI
IPC: F24D5/00
Filed: 1984-02-28
Abstract: PURPOSE:To effectively recover the heat of waste water and the heat of exhaust air by a structure wherein two pipes are abutted against a rib in a foam insulating case so as to install one set of said two pipes in an underfloor space by using one pipe as a drain pipe and the other pipe as a feed water pipe and at the same time to install the other set of said two pipes in an attic space by using one pipe as an exhaust air pipe and the other pipe as an supply air pipe and, in addition, a fan is provided in the exhaust air pipe. CONSTITUTION:When hot water is used at a kitchen and drained, the heat in the waste water heats the air in a vent layer 3 and consequently the heated air ascends. On the other hand, the air in the vent layer 3 is cooled by the cold water flowing in a feed water pipe 4 and consequently the cooled air descends. The convection of the air develops due to the existences of the ascending air and the descending air and causes to absorb the heat in the waste water in the feed water. During the winter, a fan 6 is rotated to exhaust the air in a room in order to change it. The pressure difference due to the exhaustion of the room air brings the outside air through a pipe 4 in the room. At that time, the heat of the exhaust air passing through a pipe 5 heats the air in the vent layer 3, while the pipe 4 cools the air in the vent layer 3. The resultant temperature difference causes the convection so as to absorb the heat of exhaust air in the cold air in the pipe 4 in order to perform the recovery of the waste heat.

Title: Racket frame
Inventor: AWANO TETSUYUKI
IPC: A63B49/02
Filed: 1988-02-19
Abstract: PURPOSE:To make it possible to enhance the speed and directional properties of a ball hit by the tip end of a frame racket section by letting the dimensional distribution in thickness at the frame racket section, a shaft section and a grip section be equal in a specified range along the axial line in the longer direction of a frame, and thereby setting the natural frequency of the frame in a specified range. CONSTITUTION:A frame is formed with a hollow section 10 made of FRP in a rectangular cross section. And as for the dimensional distribution in thickness along the axial line in the longer direction of the frame, t1 of a frame racket section 2, t2 of a throat section 3 and t3 of a shaft end section 4a on the grip section 5 side except the throat section 3 shall be equal in thickness within a range of 23-28mm, and the thickness S2 of the FRP outer shell of the throat section 3 is concurrently made greater than S1 of the frame racket section 2 and S3 of the shaft section 4 on the end section 4a side so that the natural frequency of the frame 1 is set in a range of 160-260Hz. This constitution thereby allows the restorating position of the frame racket section at the time of hitting a ball to be in good agreement with the position where the ball is separated from the gut stretched surface so as to keep the ball accurate in direction, thereby enabling oscillation energy to be effectively utilized for accelerated driving force at the time of reflex action to the ball.

Abstract: PURPOSE:To eliminate exactly a noise whose frequency is easily variable and large such as a commercial frequency noise, etc. by subtracting that which corresponds to a noise waveform except a flow signal waveform in a Fourier component, and eliminating a noise waveform in a Fourier space. CONSTITUTION:A noise eliminating circuit 1 amplifies suitably an input signal (a) from a transmitter part received by a buffer amplifier 6, by an amplifying circuit 10, and Fourier-converts an amplified output (b) by the first Fourier converting circuit 11.

Title: Optical vibration detector
Inventor: OZAWA AKIO
IPC: G01H9/00
Filed: 1995-02-24
Abstract: PURPOSE: To obtain an optical vibration detector which can detect vibration accurately by acquiring a vibration data with high S/N ratio. CONSTITUTION: A CPU 31 acquires a vibration signal and monitors the receiving signal level simultaneously and invalidates the acquired vibration signals when the receiving level drops below a set level during a predetermined time. In other words, only when the receiving level does not drop below a set level during acquisition of receiving level signal, the acquired vibration signal is stored as a vibration data. The acquired vibration data is subjected to FFT in the CPU 31 and a decision is made whether the frequency spectrum is valid based on the features thereof. The CPU 31 decides whether an insulator is acceptable based only on the valid frequency spectrum.

Title: Plasma cvd device
Inventor: TSUKADA MASASHI
IPC: H01L21/205
Filed: 1988-02-20
Abstract: PURPOSE:To enable substrates in even film quality to be formed stably by a method wherein, within an RF plasma device with a pair of parallel flat plate type electrodes, small protrusions are distributed on an electrode surface on the side whereto a substrate is not set. CONSTITUTION:Small protrusions 5a in height of several mum-several scores of mum are distributed on the surface of an electrode 5 on the opposite side to another electrode 1 whereto a substrate 4 is to be set. As a result, abnormal discharge states are brought about around respective small protrusions 5a, however, this discharge states extending to the whole plasma state, a little ruggedness etc. on the substrate side can be neglected. Consequently, on an average, the plasma states may be stabilized. Furthermore, the electron density and energy are augmented in the regions around the small protrusions 5a so that the plasma states may be controlled by changing the density of the small protrusions 5a from the center of the electrode 5 to the peripheral parts thereof. Through these procedures, even film quality can be assured even in the cases of setting multiple substrates or large-sized substrates.
