Title: Stamp having sheet stand
Inventor: TANIGAWA MASAO
IPC: B41K1/50
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To affix stamp-faces having vartious designs simply and surely by forming a seat stand comprising a top part and a stand part positioned at its outside out of an elastic material sheet and providing a liquid-immersed seal with its printing face downward at the top part. SOLUTION: A stamp 1 having a sheet stand is formed by sticking a top face 15 of a square plate liquid-immersed stamp 14 to a bottom face of a top part 5 of the sheet stand. At sealing on a mount D by using this stamp 1, a hand is placed on the top part 5 so as to press it down and abut the bottom face of the liquid-immersed stamp 14 against the mount D for affixing the stamp. At this time, sliding sections 9 at four parts of the head of a stand section 13 slide outwardly on the mount D by interlocking with the press-down of the top part 5, so that the stand section 13 expands circularly. When the hand is removed after stamping, the sliding sections slide on the mount D inwardly so as to return to the former positions.

Title: Chattering preventing circuit
Inventor: FUKAZAWA HIDEO
IPC: H04M1/50
Filed: 1981-12-10
Abstract: PURPOSE:To prevent chattering with simple constitution, by using a part of a flip-flop for clock frequency division in common for the timing of output flip- flop set and reset. CONSTITUTION:In inputting ''1'' to an input terminal IN, an output of an AND circuit G11 goes to ''1'' and FFs 6-10 start counting. When the output of a flip- flop FF7 goes to ''1'', ''1'' is outputted at an output terminal OUT. Since the output of an NAND circuit G17 goes to ''0'' during this time, an output of an OR circuit G13 goes to ''0'' to clear the FFs 6-10. When a contact is opened, a circuit G12 outputs ''1'', the FFs 6-10 start counting, the FF10 outputs ''1'', the output terminal OUT goes to ''0'', the output of the NAND circuit goes to ''1''  for the preparation of the next input. The chattering of the contact is recovered during this operation time.

Filed: 1986-08-26
Abstract: PURPOSE:To permit the reconstruction of different reconstruction images by selectively using a spot light source and scattering light source as a reconstruction light source for a hologram on which the images are recorded as discontinuous two subject images. CONSTITUTION:The two images, i.e., the image recorded by remote distance photography and the image recorded by short distance photography are reconstructed if the light from the spot light source is irradiated as the reconstruction light and only the image recorded by the remote distance photgraphy is reconstructed if the light from the scattering light source is irradiated as the reconstruction light in the case of reconstructing the hologram 2. The hologram which can be used includes a Lippmann hologram, laser reconstructed hologram, image hologram, rainbow hologram, etc. A white spot light source 3, laser light source, etc. are used as the spot light source for the reconstruction light source. The light obtd. by passing the light from a fluorescent lamp 4 or the spot light source through a light scattering plate, etc. can be used as the scattering light source. The different images are thus reconstructed by changing the reconstruction light source.

Title: Data communication system
Inventor: NAGAO KATSUYUKI
IPC: G06F13/00
Filed: 1988-08-10
Abstract: PURPOSE:To surely stop a DMAC so that restoring processing can be performed without delay even in the case of high speed transfer or in the case when a bus was not released by stopping the DMAC forcedly by detecting that DMA transfer is not performed within a time constant period. CONSTITUTION:A hardware timer circuit 43 is operated at every DMA transfer period by using a fact that a DMA (Direct Memory Access) response from a DMA controller (DMAC) 42 corresponds to the actual DMA transfer. When the DMA transfer is not performed within a time constant, the DMAC 42 is stopped forcedly, and the DMAC 42 and the hardware timer circuit 43 are initialized. Thus, since time supervision is performed regardless of a CPU cycle, the time supervision can be surely performed so that the DMAC can be stopped even in the case of the high speed transfer with no CPU cycle and in the case when the DMAC 42 does not release the bus for some reason, and besides, the CPU cycle need not be strictly supervised, and the restoring processing can be performed without delay.

Title: Air leakage inspection in plasma producing device
Inventor: YAJIMA TERUO
IPC: H01L21/203
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To detect air leakage more simply and accurately in a plasma producing device. SOLUTION: Discharge voltage, discharge current, and plasma emission intensity in a plasma producing device are correlated with the amount of air leakage under certain conditions. In other words, the amount of air leakage is in proportion to a discharge voltage value and emission intensity in the case of constant discharge current, and the amount of air leakage is in inverse proportion to a discharge current value and emission intensity in the case of constant discharge voltage. Furthermore, in the case of constant discharge electric power, the amount of air leakage is in inverse proportion to a discharge current value and emission intensity and is in proportion to a discharge voltage value.  Therefore, it is possible to detect air leakage on the basis of changes in a voltage value or a current value measured at a measuring part 38 or changes in plasma emission intensity measured at an emission intensity measuring part 40 while controlling discharge voltage, current, or electric power at a control part 32 to perform D.C. discharge between a cathode tube 26 and an anode tube 28 for producing plasma.

IPC: B01J3/04
Filed: 1987-08-12
Abstract: PURPOSE:To attempt economizations of material and energy source by inserting a closed loop reaction vessel, which is equipped with a charging pipe for reactant and a discharging pipe for reaction product, into the earth so deep as to reach a subterranean hot water zone, wherein a conversion of materials such as a direct chemical synthesis reaction is carried out. CONSTITUTION:A closed loop reaction vessel 2, which consists of a duplex or a triplex pipe and is equipped with a charging pipe 3 for reactants and a discharging pipe 4 for reaction products, is inserted into the earth so as to reach a subterranean hot water zone which exists at least 1,000m or more below the ground level. A conversion of materials such as a direct chemical synthesis reaction is carried out in an underground high temperature zone under a static or a flowing condition. Economizations of material and energy source can be attained as a result of this process. Moreover, this pressure vessel has an intrinsically safe construction against any abnormalities for the vessel, because the vessel is set so as to receive a compression from the base rock. Installation costs can be largely cut down, because the thickness of the wall of pressure vessel is allowed to be thinner than those installed on the surface of the earth.
