Title: Magnetohydrodynamic driving device
Inventor: AOYAMA GORO
IPC: H02K44/04
Filed: 1987-03-25
Abstract: PURPOSE:To make the title device highly efficient, by making a flux density near the end of the flow direction of the device so as to have a gentle gradient, in which electric eddy current will never be generated. CONSTITUTION:An electromagnetic flow coupler is constituted of a generator side flow passage 2, a pump side flow passage 3 and magnets 1, arranged in parallel to both of flow passages 2, 3, while the coupler is configured so that distances between the magnets 1 and the generator side flow passage 2 as well as the pump side flow passage 3 are enlarged gradually as fluid flow at both ends of magnetic poles in the flow direction is distant from the centers of flow passages. The magnets 1 are arranged so that the magnetic reluctance between magnets increased gradually; therefore, the density of flux in the pump side flow passage 3 is attenuated slowly in the end of the flow direction. According to this constitution, an electromotive force proportional to the flux density of the fluid in the flow passage decreases, therefore, the generation of electric eddy current may be prevented.

Title: Closed-circuit heat engine
Inventor: KANBAYASHI NORIYUKI
IPC: F03G7/00
Filed: 1988-03-25
Abstract: PURPOSE:To recover waste so efficiently by circulating a heating medium being ebulliently evaporable at room temperature or such less than that, while gasifying it by heat reception from a cold heat source, and utilizing a volumetric difference between liquid and gas. CONSTITUTION:A prime mover 1 is driven by a heating medium turned to high temperature and pressure gas by a gasifying heat exchanger 4. The heating medium, whose pressure and temperature are lowered by driving this prime mover 1, is further cooled by a liquefying heat exchanger 2, turning to a low pressure and temperature liquid. This liquefied heating medium is pressurized by a pressure-feed pump 3, and fed into the gasifying heat exchanger 4. The heating medium selects such one that is ebulliently evaporable at lower temperature than that of a supply heat source, so that even if it is a low temperature heat source, the heating medium is gasifiable in using such one. Thus, the gasified heating medium is fed to the prime mover 1 and mechanical energy is taken out.

Title: Method and apparatus for drilling rock
Inventor: HERUUITSUGU BURURITSUHI
IPC: E21C35/187
Filed: 1984-04-10
Abstract: For cutting rock by means of cutting head (1) having its bits (24) cooperating over a limited axial shifting stroke (a) with a cylinder-piston-aggregate, for example a valve (18), it is proposed to intermittently subject the cylinder-piston-aggregate to the action of pressurized fluid, thus exposing the bit (24) during its engaging the rock to percussion forces. During the phases lacking any action of pressurized fluid onto the cylinder-piston-aggregate, the bit (24) shall be pushed into its starting position. This embodiment can be realized with both hydraulic and pneumatic cylinder-piston-aggregates, noting that in case of an embodiment having a hydraulic cylinder-piston-aggregate it is preferred to design this cylinder-piston-aggregate as a valve (18) which simultaneously provides the possibility to expel pressurized liquid via a spraying nozzle (32) onto the mine face.

Title: Silver oxide battery
Inventor: TANSHIYUU SHIROU
IPC: H01M2/16
Filed: 1982-04-27
Abstract: PURPOSE:To improve the preservation performance of a silver oxide battery, and prevent any internal short circuit which might be caused during the electric discharge by making a porous synthetic resin film, which is provided in a separator layer, has a property of inhibiting transmissions of zincate ions and argentate ions and has a mean hole diameter of within a specified range. CONSTITUTION:A positive mixture 1 is packed into a positive can 2. A separator layer (A) consists of a translucent film 3, a cellophane film 4 and a porous resin film 5 which is formed by packing calcium hydroxide granular powder into the holes of a porous member before the above powder is bound with a synthetic resin. As an electrolyte with which a negative mixture 6 is impregnated, an aqueous causticalkali solution which is saturated with zinc oxide is used. As an electrolyte with which the positive mixture 1 and the separator (A) are impregnated, an aqueous caustic-alkali solution containing no zinc oxide is used. In a battery thus constituted, almost no capacity reduction is caused even after it is left at a temperature of 60 deg.C and a humidity of 90% for 100 days. In addition, a stable electric resistance is realized by adjusting the mean hole diameter of the porous synthetic resin film 5, and the preservation performance of the battery rapidly decreases when the mean hole diameter of the film 5 becomes over 100mum.

Title: Variable speed data receiver, clock restoration device and variable speed data transmitter
Inventor: YAMAUCHI MASAKI
IPC: H04L7/08
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To restore a source clock signal even in the case of sending variable bit rate (VBR) data such as Moving picture Experts Group (MPEG) 2 data via an ATM network. SOLUTION: An ATM cell sent via an ATM network is received by an ATM reception section 21. The received cell is restored into a packet by a cell disassembling adapter section 22 or the like and then decoded. The cell disassembling adapter section 22 detects a reception timing of a head cell of a frame period. A local clock section 30 detects a reception interval of a head cell based on the reception timing and restores a frame period signal CR based on the detected output. An M-multiplier 31 applies a multiple of M to a frequency of the restored frame period signal CR to restore a source clock signal SC, where M depicts a ratio of a frame period to a period of the source clock signal SC.

IPC: G06F19/00
Filed: 1992-02-24
Abstract: PURPOSE:To set a threshold level in the vicinity of a median of an input signal at all times and to detect a digital signal by detecting a peak of the input signal and setting nearly the median of the peak as a threshold voltage. CONSTITUTION:A holding voltage is set to nearly a median of a peak level by a divider comprising resistors 5, 6. When a voltage with a prescribed peak level is generated at input terminals 1a, 1b by an input signal, since a specific threshold level is set, a comparator 7 discriminates the presence of the input signal when a voltage is generated higher than the threshold level. In this case, a peak detection circuit 3 detects a new peak level and it is held by a hold circuit 4, then nearly a median of the peak level is set as a new threshold level. Thus, when the voltage generated at the input terminals 1a, 1b is larger than the new threshold level, it is detected that the digital signal is in existence.
