Title: Electromagnetic field simulation method
Inventor: HIRONO TAKUO
IPC: G06F19/00
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To improve accuracy by storing any time step value of a plurality of variables for describing an electromagnetic field in a memory, calculating from a certain time step to the next time step and renewing the content of the memory on the basis of the result to represent the calculation as canonical transformation. SOLUTION: Vector potential A and vector π of momentum conjugate therewith are used to describe an electromagnetic field. When current density becomes zero in every spot, Hamiltonian H is described by the vector A and vector π (canonical variable) like a formula (ε; permittivity, μ; magnetic permeability). Thus, calculation from a value of a time step having the canonical variable to the neat time step value is obtained from the canonical transformation having a function for making the calculation discrete as a generating function. The Hamiltonian H is made discrete by a finite element method using a serendipity cubic element so that a secondary symplectic numerical solution is applied to the Hamiltonian H. Thus, his accuracy simulation is provided.

Inventor: YOKOTA MASAFUMI
IPC: G11B7/14
Filed: 1994-03-24
Abstract: PURPOSE:To continuously reproduce information continuously recorded on a first and a second recording surfaces. CONSTITUTION:A group track and a land track adjacent to the group track are formed on both surfaces, A surface and B surface, of an optical disk l so as to extend from the inner periphery to the outer periphery. At the time of information recording/reproducing, the group track 110A on the A surface is retrieved from the inner periphery to the outer periphery by means of one optical head and, when the retrieval reaches the outer periphery, the group track 110B on the B surface is retrieved from the outer periphery to the inner periphery by means of the other optical heads 10, 20. When the retrieval reaches again the inner periphery, the land track 120A on the A surface is retrieved from the inner periphery to the outer periphery by means of one optical heads 10, 20 and, when the retrieval reaches the outer periphery, the land track 120B on the B surface is retrieved from the outer periphery to the inner periphery by means of the other optical heads 10, 20. Consequently, information reproduction and recording are continuously performed on both surfaces.

Title: Sealed-type alkali battery
Inventor: NISHIYAMA KOICHI
IPC: H01M4/52
Filed: 1989-03-06
Abstract: PURPOSE:To make it possible to use a paste-type cathode for a sealed-type battery without altering a conventional anode by installing a paste-type cathode containing a cathode active mass of oxides of >=2-valent nickel prepared by chemical oxidation of nickel hydroxide powder or a mixture of the oxides with hydroxides of >=2-valent nickel. CONSTITUTION:Nickel hydroxide in a paste-type cathode containing a cathode active mass of solely oxides or >=2-valent nickel prepared by chemical oxidation of a nickel hydroxide powder or a mixture of the oxides with hydroxides of >=2-valent nickel becomes in charged state in an equivalent of the total of (d) and (d). By using the cathode, even when anode which is supposed to be combined with a sintered-type cathode is combined with the cathode and used for a sealed-type battery, the battery can have well balanced capacity. By this way, in the case that the paste-type cathode is used, an anode does not need to be prepared specifically and even if the anode is so prepared as to be combined with a sintered-type cathode, a sealed-type battery having well balanced capacity can be prepared by using the cathode and anode.

Title: Data signal regenerating circuit for still video apparatus
Inventor: SATO KOICHI
IPC: G11B20/02
Filed: 1989-03-07
Abstract: PURPOSE:To prevent a noise from being generated in a reproduced picture by a data signal at the time of regeneration by executing ON/OFF control to shape the waveform of the data signal read from a recording medium. CONSTITUTION:When the tracking of a magnetic head 16 is completed and the reading of a multiple recorded signal is started, a microcomputer 12 turns on a data read signal. Accordingly, out of the multiple recorded signals read by the head 16, the data signal passing through a BPF 26 is shaped for its waveform by an waveform shaping circuit 32, demodulated by a DPSK demodulation circuit 36 and supplied to the microcomputer 12. When the data signal is once decoded, the microcomputer 12 turns off the data read signal and stops waveform shaping operation in the waveform shaping circuit 32. Accordingly, the waveform of the data signal read following this process and thereafter from the prescribed track of a magnetic disk 10 is not shaped and the signal is not outputted to the microcomputer 12.

IPC: A47C19/14
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To provide an elevator constructed such that a lifting operation can be carried out at any position of the periphery of a bed without the need for the supply of motive power and a locking operation at the lower position. SOLUTION: A pair of legs 6 and a linearly displacing type spring means 7 are provided, and a component of the energizing power in the raising direction of the spring means 7 with regard to each of the pair of legs 6 is minimum at the lower position and increases as a bed 1 is lifted. At the lower position, the weight of an elevating part of the bed 1 exceeds the energizing power in the raising direction of the spring means whereby the lower position of the bed 1 is maintained without the need for a locking device. In a lifting operation, if a workman applies an auxiliary lifting power to the elevating part of the bed 1 at the lower position, the contributive rate of the spring power in the direction of raising the legs 6 increases gradually as the bed 1 is lifted, so the 1 bed can be lifted automatically without the need for the motive power.
