Title: Semiconductor producing device member
Inventor: ENOMOTO AKIHIRO
IPC: C23C16/32
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To make excellent the corrosion resistance to strong acids such as hydrofluoric acid and nitric acid and to suppress the generation of particle contamination by controlling the particle size of silicon carbide particles forming a CVD film and the average surface roughness of a base material before the formation of the CVD film to specified ranges. SOLUTION: The particle size of >=80% of the particles of silicon carbide forming a CVD film is controlled to <=10 μm, desirably to 0.1 to 1 μm, and the obtd. CVD film is made dense. The porosity of the CVD film composed of silicon carbide is <=3%, and, furthermore, the closer to 0% as possible, the more desirable. Since the CVD film is dense, even in the case the thickness of the film is small so as to be several μm, it exhibits sufficient corrosion resistance to strong acid. As a base material, the one composed of quartz and whose surface roughness before the formation of the CVD film is 1 to 10 μm is used. When this substrate is used, stress generated on a space between the substrate and the CVD film caused by thermal expansion is dispersed, so that the peeling of the CVD film and cracks are made hard to be generated.

Title: Polarization multiplex two-way optical transmission system
Inventor: NOSU KIYOSHI
IPC: H04B10/2507
Filed: 1978-05-31
Abstract: PURPOSE:To prevent crosstalk and the attenuation of energy to separate optical signals, by separating light pathes or optical signal on a basis of thier directions so that optical signals issued by the optical signal source of the other side may be led to photo detectors mutually. CONSTITUTION:The ray issued by optical signal source 1 is adjusted to parallel beams by lens 4 and are connected to optical fiber 3 through polarizor 8 by lens 5, and optical signals transmitted through fiber 3 are connected to polarizor 8 in the other side by lens 5 and are focused through polarizor 8 by lens 7 and are led to photo detector 2. Here, two-way optical signals are so arranged that polarization surface may be orthogonal to each other when they are transmitted through fiber 3, and light pathes of optical signals can be separated by their directions, and therefore, optical signals issued by optical signal source 1 of the other side are led to photo detectors 2 mutually. As a result, the attenuation of energy is not received because two-way optical signals are separated, and crosstalk accompanied with separation can be prevented.

Title: Impact relaxation device for percussion tool
Inventor: NITTA NORIO
IPC: F16F7/00
Filed: 1988-03-18
Abstract: PURPOSE:To relax the forward impact force of an intermediate striking hammer to prolong the life of a percussion tool, and reduce the weight of the tool by adhering a cushioning material to the inside of a front cover. CONSTITUTION:A striking hammer 4 strikes at an intermediate percussion hammer 7, and further the intermediate striking hammer 7 strikes at a tip-cutter 1.

Title: Control device
Inventor: YANASE MASAO
IPC: G03G15/00
Filed: 1980-05-19
Abstract: PURPOSE:To surely detect the presence or absence of an inductive load such as total counter by detecting the counter electromotive force generated when a DC inductive load is turned off and performing operation controlling by the detection output thereof. CONSTITUTION:When an L load driving signal S1 is inputted by paper feeding, etc., a transistor (TR) Q2 goes on and an L load goes on. Since the signal S1 is also inputted to a timer T, the timer T is set, and after t1 second, the TRQ2 goes  off, hence the L load goes off as well, thereby generating counter electromotive  force. This is detected by a photocoupler P, and is inputted to the reset terminal of a timer T, hence the timer T is reset and a thyristor SCR does not go on. If a resistance, etc. is connected in place of the L load, no counter electromotive force is generated and therefore the timer T is not reset. Hence, after the set time, the thyristor SCR is turned on by the signal of an H level from the output terminal of the timer T, thereby driving a relay RL and disabling the copying key.

IPC: D06F33/02
Filed: 1988-03-18
Abstract: PURPOSE:To shorten the time required as well as to get rid of any waste watt consumption by stopping a dewatering process only when a detecting element has detected any unbalance of washing at the first time dewatering process, while installing a control part which operates an informing means. CONSTITUTION:When operation is started, a drain valve 21 is opened by a control circuit 19, and a drain process is started. Next, when a dewatering process is started, whether this dewatering process is the first time or not is judged, and furthermore when an unbalance detecting sensor 16 detects any unbalance in a dewatering bin, the control circuit 19 stops a motor 10, having a display LED 17 lighted, and it displays the unbalance, while it operates a buzzer 18. A user corrects the unbalance by himself and, after the dewatering process, transition to a rinsing process, the drain process and the dewatering process from a feedwater process takes place. Since this dewatering process is the second time this time, if detecting the unbalance, the dewatering process is temporarily stopped, shifting to the feedwater process, and any deviation of washing is eliminated at a stirring process, and the unbalance is automatically corrected, thus operation is shifted to such likewise afterward.
