Title: Electromagnetic device
Inventor: KAKEHASHI HIDENORI
IPC: H01F17/00
Filed: 1991-08-23
Abstract: PURPOSE:To obtain an electromagnetic device wherein a leakage flux can be reduced by a method wherein an insulating film 11 on which a conductor layer having a strip- shaped pattern and a magnetic-substance layer having a U-shaped pattern surrounding its three sides have been formed is wound in such a way that the central side of the conductor layer is situated at the inside. CONSTITUTION:An insulating film 11 on which a conductor layer 13 having a strip- shaped pattern and a magnetic-substance layer 12 having a U-shaped pattern so as to surround three sides of the conductor pattern 13 having the strip-shaped pattern have been formed is wound in such a way that the central side of the magnetic layer 12 having the U-shaped pattern is situated at the inside. For example, a conductor layer 13 having a strip-shaped pattern is applied to a long insulating film 11 along its lengthwise direction, and a magnetic-substance layer 12 having a U-shaped pattern so as to surround three sides including one side and both ends in the lengthwise direction of the conductor layer 13 is applied to it. In the magnetic-substance layer 12, the central side is set to be wide, and a gap 11a for insulation use is opened between it and the conductor layer 13. Lead terminals 14, 15 are bonded to both end parts of the conductor layer 13.

Title: Hub unit test system
Inventor: WAKABAYASHI MASAMI
IPC: H04L12/44
Filed: 1993-08-27
Abstract: PURPOSE:To test a hub unit quickly by counting number of times of transmission up to the reception of a state information signal after the transmission of a predetermined signal is started and comparing the number of times with a specified value to discriminate normal and abnormal state being an upper limit of a collision number of times on a port. CONSTITUTION:A hub unit test function 17 of a personal computer 13 gives signals TD+, TD- to ports 1,2 as a transmission command via a tester 12. Since the ports 1,2 receive them simultaneously, a collision is detected and number of times of collision is counted by a counter of a hub unit 11. When the count reaches 30 times or over, a state information signal (PART signal ON) is received by the test function 17 via the tester 12 to discriminate whether or not the signal is a state information signal, and in the case of YES, number of times of collision is displayed, and in the case of NO, the collision number of times is increased by 1 and the processing is restored to the original state. When a display number of times is 30 times or over, the upper limit of collision number of times is set normally and when lower than 30 times, it is discriminated that an upper limit of collision number of times on the port is in error.

IPC: F16H55/08
Filed: 1993-08-27
Abstract: PURPOSE: To exhibit a good anti-ratcheting characteristic and to prevent an interference generation between teeth by forming a flank surface of a tooth of a cross section in a longitudinal direction of a sprocket to a specific tractrix curve shape. CONSTITUTION: A main portion 110 of flank surfaces 112, 114 of belt teeth engaged with respective sprocket teeth is made to a tractrix curve represented by a formula and is transited to a belt tooth tip end 116 using a continuous portion of the tractrix curve. The belt teeth 118 are completely engaged with a groove 120 of the sprocket 112 at a ration of h/b=0.695. When belt teeth 128 are inserted to a sprocket groove 130, a contact and a tangential sliding contact are caused between the flank surface 124 of the belt tooth and a sprocket tooth 126. Thereby, the belt has an excellent anti-ratcheting characteristic by the relatively sharp flank surface 124 and an interference of the belt teeth 118 is not at all caused to realize a smooth operation.

IPC: H01L21/316
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To reduce oxidation temperature by turning a part of a clean silicon surface into an temporarily inactive state to oxygen molecules. SOLUTION: Inactivation process of a silicon surface is performed by irradiating a clean silicon surface with hydrogen in the atomic state. Hydrogen gas in the range from 10<-5> Pa to 10<-4> Pa is introduced in a stainless tube having a diameter of 4 mm which is directly connected with a variable leak valve, and hydrogen molecules are dissociated by a coil type tungsten filament, with which a specimen is irradiated. The amount of hydrogen gas is controlled by the degree of vacuum in a specimen preparing vessel. While the clean surface is maintained at a constant temperature of 650 K by current heating, the specimen is irradiated for 5-10 minutes with hydrogen in the atomic state. The hydrogen-terminated Si(100)-2×1 surface is adjusted.  By simultaneously topping power sources of the tungsten filament and the current heating, the state of the surface at the temperature is quenched.

IPC: H01M10/05
Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To enhance discharge characteristics of a battery using a thin positive electrode plate and decrease the dispersion of the discharge characteristics by using nickel oxyhydroxide or its derivative having specified moisture content or more. SOLUTION: Nickel oxyhydroxide or its derivative containing 650 ppm or more moisture used in a positive electrode active material has layer structure, moisture presumably contributes to stability of a lithium diffusion layer, and correlation is present between the moisture content and discharge capacity. The moisture content of 8000 ppm or less is preferable and has no adverse effect on a negative electrode caused by dissolving in an organic electrolyte solution. A positive electrode active material having performance in a constant level or higher and no dispersion of the performance can be manufactured and industrial production is made easy. The derivative is prepared by substituting part of nickel of the nickel oxyhydroxide with cobalt, aluminum, zinc, and manganese.  The specified ratio of moisture is simply contained by controlling humidity in exposing atmosphere, or moisture, temperature, and degree of pressure reduction in a drying process.

Title: High-speed data transmission and synchronization system
Inventor: KATO YUJI
IPC: H04J3/06
Filed: 1985-09-28
Abstract: PURPOSE:To facilitate frame synchronization by using a phase changeover circuit to switch the phase of a clock signal when no frame synchronization is taken for a prescribed period and using the clock signal at the phase when the frame synchronization is taken to key received data. CONSTITUTION:When the frame synchronization is not taken for a prescribed period in a frame synchronization circuit 11, a changeover control signal CS is fed to a phase changeover circuit 12 from a changeover protection circuit 13 to invert a flip-flop 15. Then the phase of the clock signal CK is changed over. Thus, since the rising phase of the clock signal CK is nearly at the center of data, the data is keyed and the frame synchronization is taken in the frame synchronization circuit 11. When the frame synchronization is taken, since a frame synchronization detection signal FD is fed to the change-over protection circuit 13, the changeover control signal CS by the overflow of a counter 14 is not outputted to allow the phase changeover circuit 12 to hold the phase of the clock signal CK as it is. Thus, the high-speed data transmission of 500MHz is attained.
