Filed: 1985-05-09
Abstract: PURPOSE:To continuously and smoothly change impedance by smoothing the movement of the internal conductor in a stub and to reduce the abrasion of a guide shaft, by transmitting driving force by using a rubber roller. CONSTITUTION:A rubber roller 46 is rotated to the necessary direction of either one of the directions shown by a double-arrow FA by driving a pulse motor and the receiving plate 44 contacted with the rubber roller 46 is moved to either one of the directions shown by a double arrow FB by the rotation of said roller 46. Because one end of a fixing plate 42 is fixed to the receiving plate 44, the fixing plate 42 also slides along a fixed guide shaft 48 with the sliding of the receiving plate 44. Because the internal conductor 30B of a stub 30 is engaged with one end of the fixing plate 42, the internal conductor 39B also slides as shown by an arrow FC with the sliding of the fixing plate 42. Hereupon, because the receiving plate 44 receives the transmission of the rotary force of the rubber roller 46 to be slid in an extremely smooth manner, the internal conductor 30B also smoothly moves to the direction shown by the arrow FC.

Filed: 1994-04-11
Abstract: PURPOSE:To improve the joining strength and the joining accuracy between the starting and finishing ends of sheet-like material by a method wherein the distance between its starting and finishing ends is held at the control value with a control pin. CONSTITUTION:Even after the starting and finishing ends S3 and S4 of sheet-like material S are pinched with upper and lower joining claws 48, 49, 36 and 37, a motor is continued to run. At this time, a cam follower 95 moves in an elongated hole 94, resulting in temporarily shut off lifting force from being transmitted to a lifting stand 26. During the shutting-off, a control pin 63 is immersingly retracted from between the starting and finishing ends S1 and S2 of the sheet- like material S, resulting in forming a gap between the ends. At this time, by being controlled by pinching, the starting and finishing ends S3, S4 are prevented from deforming.

IPC: G06F12/16
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To check the data errors in a write mode without lowering the data access speed by applying a read operation to a memory storage element that is not actually performing a write operation by interleaving and comparing this written value with that written before the said value to confirm the propriety of data. SOLUTION: A memory write/read control part 1 writes in sequence the data into the semiconductor memory parts 3 to 6. Under such conditions, the semiconductor memory part where a write operation is not actually performed is set to read the data. For instance, if the data write operations are over to the memory parts 3 and 4 while a data write operation is performed to the memory part 5, a write data check part 7 reads the data written into the parts 3 and 4 through the data read buses 11 and 12. These read data are compared with the write data which are previously fetched from a write data check data bus 8, and the coincidence is confirmed between both data.

Title: Burner
Inventor: ISHIKAWA KATSUHIKO
IPC: F23Q25/00
Filed: 1990-04-12
Abstract: PURPOSE:To sharply reduce small during ignition and extinguishment by a method wherein, in the lower part of a wick containing part, a protruding annular part is located to at least one of a wick outer cylinder or a wick guide cylinder to form a narrow part, a suction passage a suction amount of which is increased to a value higher than that of other part is located at least in one spot, and a suction means is operated during ignition or extinguishment. CONSTITUTION:A suction passage 8 has flow passage resistance decreased to a value lower than that of a narrow part 7 formed with a protruding annular part 6 of a wick containing part 4 and is relatively increased to a value higher than that of other part. Thereby, even when the gap of the wick containing part 4 is fluctuated due to a difference in the thickness and the size of a wick 5, an approximately constant amount can be sucked. Further, even when the gap of the wick containing part 4 is fluctuated according to the degree of roundness of a wick guide cylinder 2, the wick 5, and a wick outer cylinder 3 and due to a case of a wick outer cylinder 3 being eccentrically fixed to an oil tank 1, an approximately constant amount can be sucked through the suction passage 8. Eccentricity of the wick outer cylinder 3 when it is fixed to the oil tank 1 by means of the protruding annular part 6 is reduced. Thus, there is no need to suppress a suction amount so that the generation of white smoke due to an excessive suction amount occasioned by the fluctuation in a gap of the wick containing part 4 and the generation of a small due to defective combustion are prohibited. Reduction of a small reducing effect due to undersuction is prevented from occurring and an optimum suction amount can be stably ensured.

Title: Ghost eliminating device
Inventor: INMI MASABUMI
IPC: H04N5/21
Filed: 1982-06-09
Abstract: PURPOSE:To realize to improve the equalizing effect and equalizing speed of an MAE method, by changing continuously the value of alpha in proportion to the size of a ghost signal added to an output signal H(t) in order to make the locus of a tap gain coefficient Cj(1) to a Ci<0> pseud like of an MSE method. CONSTITUTION:If the size of an output Eg [this is equivalent to the size of a ghost signal applied to an output signal H(t)] of an integrator 915, which integrates ¦E(t)¦ of an instantaneous error E(t) which is an output of a differential amplifier 46, is large, the value of the gain of an amplifier 1010 becomes large. On the contrary, the smaller the output Eg of the integrator 915, the smaller the gain of the amplifier 1010 continuously. Outputs of integrators 911-914 are equivalent to a correction amount Mj of a tap, and the gain of the amplifier 1010 is equivalent to a constant alpha. Therefore, in such a circuit constitution, an equalizing operation is performed in larger state of alpha in initial stage, because the ghost signal applied to the output signal H(t) is large. When the number of times of equalizing is increased to make smaller the ghost signal applied to the output signal H(t), the equalizing operation is performed in smaller state of alpha gradually.

Title: Manufacture of semiconductor device
Inventor: IKUSHIMA YASUTAKA
IPC: H01L21/316
Filed: 1987-04-20
Abstract: PURPOSE:To obtain a high quality IC with no stress concentrated in the transition region, by using a non-oxidizable mask constituted of a plurality of nitride films having different resistances to oxidation. CONSTITUTION:By a plasma CVD method, a first nitride film 3 and a second nitride film 4 are deposited in order on the upper surface of a silicon oxide film 2 on the surface of a silicon wafer 1. Then, by a selective etching, a non- oxidizable film 7 of two-layer structure is formed only on an element-forming region, and the surfaces the silicon oxide film 2 and the non-oxidizable film 7 are covered by a third nitride film 5. By applying an anisotropic etching, the third nitride film 5 is left on the sidewall of the non-oxidizable film 7. Finally, a field oxide film 8 is selectively formed, by applying the non-oxidizable film 7 and the third nitride film 6 to masks. As the resistance to oxidation of the first and the third nitride film is smaller than that of the second nitride film, the sidewall 6 is also adequately oxidized, and the length L of a transition region 9 becomes about 0.1mum. Thereby, stress does not concentrate to the transition region, so that the quality of IC is improved.

Title: System for synchronizing plural waves
Inventor: MISHIRO TOKIHIRO
IPC: H04L27/38
Filed: 1988-04-20
Abstract: PURPOSE:To speedily lead in synchronization even if there is a pilot signal by providing a tracking type carrier reproducing means in a reference reception equipment and permitting a slave reception equipment to execute quasi synchronization detection by the reproduced carrier and to trace a phase. CONSTITUTION:One reception equipment (reference reception equipment) 1 among plural reception equipments 1 executes tracking type carrier reproduction by using orthogonally detected demodulation data. The other reception equipments (slave reception equipments) 2-1-2-n execute quasi synchronization orthogonal detection 21 and phase tracking 22, whereby demodulation data without phase rotation can be obtained. Since an SCPC(Single Channel Per Carrier) channel (except for S1-SN:SR) having information, for example, requires high speed synchronization, the difference of frequencies comes to be only the difference of transmission frequencies without including the difference of a common frequency if the reproduced carrier is used as the carrier for quasi synchronization detection. Thus, high speed tracking is attained by phase tracking.

Title: Camera capable of compensating focus variation with temperature
Inventor: TSUJI SADAHIKO
IPC: G03B3/00
Filed: 1982-06-09
Abstract: PURPOSE:To eliminate the influence of temperature exerted on the variation of focus by varying the relative distance between an image formation system and an image formation surface according to temperature when a material which varies considerably in refractive index due to change of temperature is used as part of a zooming lens. CONSTITUTION:The material which varies considerably in refractive index due to change of temperature, e.g. synthetic resin, etc., is used as part of the 4th lens group 4 among zoom lens groups. The helicoid 7a of the holding lens barrel 7 of the lens group 4 engages the helicoid 6a of a fixed barrel 6 threadably and an operating member 8 projects out of a hole part 9a; and marks 10 indicating high, intermediate, and low temperature conditions are provided on a main body 9. If part of the lens group 4 varies in refractive index due to change of temperature, an image point shifts in position. At this time, the lens barrel 7 is moved forth or back through the rotation of the operating member 8 to vary the relative distance between the lens group 4 and image formation surface. Thus, the influence of temperature exerted on the variation of focus due to change of temperature is eliminated easily.
