Patent JP-H02185110-A (JP)
Title: Interface circuit
Inventor: YAMANAKA NAOAKI
IPC: H04L25/03
Filed: 1989-01-12
Abstract: PURPOSE:To normally decide the low/high level of each input signal even in case of the variation in level during transmission by using the middle voltage between the high level and the low level of a clock signal as the discrimination voltage to decide the level of each input signal. CONSTITUTION:An input signal is inputted, ideally, in the ECL level on a line 2-10. In an input buffer 3-10, what is called a low-pass filter is realized with a resistance Rh and a capacity Ch. A voltage having an approximately middle value between the high level and the low level of the clock signal is generated on a reference voltage VBBh signal line 4. The DC component of the clock signal is equivalently extracted by this voltage generation, and a reference voltage VBBh is always adjusted to the middle value between the high level and the low level of the input signal though the voltage level is varied by the transmission loss or the like. The reference voltage VBBh generated in the input buffer 3-10 is supplied to the other input buffers 3-1 to 3-9 through the voltage VBBh signal line 4.

Filed: 1987-01-16
Abstract: PURPOSE:To prevent adsorption of a magnetic head by forming a magnetic thin film having 40-100Angstrom  surface roughness on a nonmagnetic substrate of <=40Angstrom  surface roughness. CONSTITUTION:A magnetic thin film having 40-100Angstrom  surface roughness Rmax is formed on a substrate having a super-position surface of <=40Angstrom  Rmax.

Abstract: PURPOSE: To improve a heat transfer to fluid from a surface through the reduction in bending of a heat collecting tube, by a method wherein a support, made of a flat steel plate, is located at the inside of the heat collecting tube.  
     CONSTITUTION: In a solar heat collecting device in which a paraboroidal mirror 3 is placed at the rear of a heat collecting tube 1, a flat steel plate 4 is inserted into the heat collecting tube 1 so that sides of the plate 4 are positioned in contact with the inner wall of the heat collecting tube 1 on the side of the paraboroidal mirror 3 and on the side of a plane mirror (not shown). This increases a moment of inertia of area on a y-axis of the heat collecting tube 1, and reduces the bend of the heat collecting tube 1 for the reduction in breakage of a vacuum heat insulating glass tube 2. The thermal conduction of the steel plate 4 so inserted diminishes a temperature difference in the circumferential direction of the heat collecting tube 1, and thereby the heat collecting tube 1 is further decreased in bending.

Abstract: PURPOSE:To obtain at low temperatures an oxide superconducting thin film as a single crystal of C-axis orientation, by film formation of a target consisting of Y1+aBa2+yCu3+xO7-delta, through sputtering, using neutralized ion beams while blowing O2 gas of specified partial pressure range on a SrTiO3 substrate. CONSTITUTION:A vacuum tank 1 is evacuated to a level of 10<-7>Torr followed by raising the temperature of a substrate 12 to 575-700 deg.C. Concurrently, O2 gas 15 is blown against said substrate 12, and after a lapse of a specified time when the substrate temperature becomes constant, a sputtering ionic source 4 is actuated to carry out film formation. When the thickness of the film to be formed reached a specified level, the operation of the ionic source 4 is stopped and the partial pressure of O2 in the tank 1 is brought to 10<-1>Torr followed by annealing to obtain the objective single crystal superconducting thin film. When an oxide consisting of Y1Ba2.2Cu3.2O7-delta is used as the target, SrTiO3(100) single crystal as the substrate, and the O2 partial pressure on the substrate is varied at the temperature of said substrate of 640 deg.C, the superconduc tivity of the film formed is given in Table 1; in this case, 10<-3>-10<-1>Torr is optimum as the O2 partial pressure on said substrate.

Filed: 1978-01-27
Abstract: PURPOSE:To prevent the application of input voltage directly to the PN junction of diffusion resistance layer, by constituting a part of the input side of the input protection resistor with polycrystal semiconductor and other parts with conventional diffusion resistance layer. CONSTITUTION:Since the polycrystal semiconductor resistance layer 26 is located closer part to the input terminal than the diffusion resistance layer 22, the forward voltage due to noise such as undershooting or high voltage due to static electricity is fed to the diffusion resistance layer 22 in the form that is reduced with the resistance layer 26. Thus, unnecessary carrier injection from the PN junction of the diffusion resistance layer 22 is restricted and the noise margin is increased, the destruction of the PN junction is restricted and the strength withstanding the static electricity can be increased.

Title: Commutator motor and magnetizing device
Inventor: NAKAYAMA TADAHIRO
IPC: H02K15/03
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of the brush and commutator of a commutator motor by arranging a plurality of permanent magnets respectively carrying rotors wound with coils on the inside at such intervals that no commutation occurs in the rotors and evenly forming two or more main magnetic poles in each magnet and auxiliary magnetic poles which are opposite in polarity to those of the main poles in about a half-length part of each magnet in the axial direction. SOLUTION: Permanent magnets 13 are magnetized so that main N poles 20 and main S poles 21 can be formed evenly in the magnets 13. The magnets 13 are fitted to a frame so that the poles 20 and 21 alternately change their places in the circumferential direction. The angle of rotation at which an induced voltage is generated across the coil of a rotor by commutation is represented as θ and the lengths of the magnets 13 in the axial direction are represented as L. Auxiliary magnetic poles 20a and 21a which are opposite in polarity to those of the poles 20 and 21 are formed at the boundary sections between the poles 20 and 21 within the range of the angle θ and a length of L/2 in the axial direction. In addition, the intervals between the magnets 13 in the peripheral direction are set at 2.  Therefore, the cost of a commutator motor can be reduced by reducing the number of parts and the deterioration of the brush and commutator of the motor can be prevented by suppressing the occurrence of sparks from the brush.
