Title: Oiler of oiling device for trolley line
Inventor: NAGASAWA HIROKI
IPC: B60M1/02
Filed: 1984-02-09
Abstract: PURPOSE:To uniformly oil a trolley line without causing bliding in an oiling hole even if air temperature changes by providing an oiling member having the oiling hole in a tube belonging thereto and having a small coefficient of thermal expansion while providing an interval member opposing, spaced in a prescribed interval, to the hole. CONSTITUTION:Oil passages 9a are bored in a tube 9 at every fastening positions of the tube, and the oil passages 9a are respectively covered with oiling members 24. The oiling member 24 is formed by metal having a smaller coefficient of thermal expansion but higher rigidity than those of the tube 9. The above member has a cylindrical part 25 for covering an outer circumference of the tube 9 therewith and blocking the oil passages 9a and a flange part 26. A cylindrical space partitioned by the oiling member 24, a partition member 60, and a flange part 26 forms an oil reservoir 61, in which oil is stored at all times irrespective of an oiling or non-oiling period. Since an oiling hole 25a for supplying the oil into the trolley line 4 is bored in the metal oiling member 24, dust from the outside sticks to the surface of the oil and does not reach the oiling hole 25a without exerting a bad influence thereon even if the air temperature and a mounting state change.

Title: Magnetic propulsion device
Inventor: KAWAHARA TETSUO
IPC: B64G1/32
Filed: 1990-01-31
Abstract: PURPOSE:To obtain a semipermanent propulsion device adopted for a space navigation body by using the electromagnetic force of an electromagnetic application rod and a ground magnetic field to generate propulsion force, and magnetically shielding an interval between the electromagnetic force application rod and a d.c. electric current control circuit to improve the generation effect of the propulsion force. CONSTITUTION:A magnetic field existing in the earth and a magnetic field to be yielded by electricity passing through an electromagnetic force application rod 2 are applied to generate propulsion force. In this instance, the direction and the magnitude of the electricity to pass through the electromagnetic force application rod 2 are controlled by a d.c. electric current control circuit 3 which controls an electric current to be supplied from an electric source 4. Hereupon, the d.c. electric current control circuit 3 is influenced by the same magnetic field as the electromagnetic force application rod 2, so that each electromagnetic force applying to them is canceled each other. In order to prevent it, the d.c. electric current control circuit 3 except for the electromagnetic force application rod 2 is housed in a magnetic shield box 1. Consequently, the propulsion device of a semipermanent space navigation body can be obtained without necessity of loading fuel and propellant.

IPC: H02N2/00
Filed: 1989-01-31
Abstract: PURPOSE:To damp unnecessary vibration reflected via an output transmitter, to reduce noise and to prevent output from lowering by inserting a vibration absorber between the output transmitter and a connection plate. CONSTITUTION:An apparatus has a structure in which a third vibration absorber 26 such as rubber is provided between a first connection plate 6a and a second connection plate 6b.

Title: Digit balance precharge circuit
Inventor: OYAMA JUNICHIRO
IPC: G11C11/409
Filed: 1990-01-31
Abstract: PURPOSE:To reduce the power current by providing a means which performs the balance precharge of a pair of digit lines synchronously with a refresh request signal which is automatically and internally produced and right before an internal refresh action only when this internal refresh action is automatically carried out. CONSTITUTION:A precharge circuit is controlled by an external control signals, the inverse of CE and the inverse of RFSH and then activated when one of both signals, the inverse of CE and the inverse of RFSH is set at a low level. If the signal, the inverse of CE is set at a low level, both row and column addresses are fetched with the external input. Then the word line corresponding to the row address is raised up for execution of a refresh action. When the signal, the inverse of RFSH is set at a low level, the word line corresponding to a row address produced by an internal row address generating circuit 3 is raised up for execution of a refresh action. Furthermore a self-refresh mode is starts when a certain set period elapsed with the signal, the inverse of RFSH kept at a low level. Thus the memory cell selected by a row address produced by the circuit 3 is refreshed in each fixed cycle synchronous with a refresh timer. As a result, the power current can be reduced.

Abstract: This invention relates to a method of controlling the energy management of a system for catching, accumulating and transferring heat comprising a heat collector and a heat accumulator of the thermally stratified type forming part of a heat recovery circuit adapted to pass a heat transport fluid, said heat accumulator forming furthermore part of a consumer circuit adapted to pass the heat transport fluid. Experiments have now shown that excellent efficiency is obtained by using this method in which the heat capacity flux, that is to say, the mass flux multiplied by the specific heat of the heat transport fluid through the consumer circuit and the mean value thereof during a selectable time interval, is determined or estimated at least by approximation and the heat capacity flux through the heat recovery circuit is adjusted so that the difference between the mean value of the heat capacity flux through the heat recovery circuit during a time interval of the same duration as said selectable time interval and said mean value of the heat capacity current through the consumer circuit is equal to a factor to be selected multiplied by the heat capacity of the heat accumulator, divided by said time interval, said factor lying between 0 and 3. Further the invention relates to a system for carrying out said method.

Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To test a logic circuit while receiving a test pattern and monitoring an output signal sequentially using a logic circuit test equipment having relatively low operating speed and available relatively easily. SOLUTION: An I/O flip-flop on the input side of a synchronization block for which normal operation is verified is operated with a system clock signal SCK while an I/O flip-flop on the output side of synchronization block is operated with a test clock signal TCK. Even in case of system clock signal SCK and test clock signal TCK having period of 50ns, the time interval between the rising of a pulse S1 and the falling of pulse T2 is 40ns and it can be seen as if a test is performed at a higher frequency. Consequently, normal operation can be verified at a higher operating speed using a logic circuit test equipment having relatively low operating speed.
