Abstract: PURPOSE:To achieve sure secret protection, by transmitting the 1st ID value for self-discrimination to a center device by each terminal and comparing the 2nd ID value returned from the center device and that of itself. CONSTITUTION:The 1st IDA, B- which identify terminals are assigned to terminals TM1, TM2 belonging to a system of one network, and at the same time, the 2nd IDa, b- having a given relation with the 1st IDs are assigned and stored in the ID register IDR. A center HOST stored a correspondence table TBL between the 1st and 2nd IDs. A dial pulse designating the center is transmitted from the terminals, the terminal and the center are connected by a public line PL and the 1st ID, e.g., A is transmitted from the terminal. The center indexes the TBL and returns the 2nd ID to the A to the terminal. The terminal collates the 2nd IDa stored in the IDR with the 2nd ID returned from the center, and when it confirms the coincidence, the correspondence is made possible and when noncoincidence, no correspondence is made.

Title: Switching regulator control circuit
Inventor: HIRAYAMA MASAHIKO
IPC: H02M3/00
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of a regulator by preventing the generation of whiskers at the output of a power transistor to eliminate the output noise of a triangular waveform generating circuit caused by a differential amount of ground noise. SOLUTION: The output of a triangular waveform generating circuit 1 generating triangular waveforms, and the output of a charging/discharging circuit 7 are inputted into one terminal of a comparator 2.

Title: Pitch error correcting system
Inventor: SASAKI TAKAO
IPC: G05B19/18
Filed: 1990-04-26
Abstract: PURPOSE:To make the movement of a machine smooth and to improve a cutting face by outputting pitch error correcting pulses at equal intervals in each section. CONSTITUTION:A pitch error calculating means 4 reads out the current value of the spindle of the machine from a current value register 3 and reads out a pitch error correcting variable epsilonn in each section corresponding to the section of the current value and an accumulated pitch error correcting variable epsilonn up to the initial point of the current value. The pitch error correcting pulses PC based upon the read data are outputted to an adder 5 at equal intervals. The adder 5 adds an interpolating pulse IP to the pulse CP and outputs the added pulse to a spindle control circuit 18, which controls a servo motor based upon the output pulse. Since the means 4 outputs the pitch error correcting variables in respective sections at the equal intervals, the machine can be smoothly moved and the cutting face can be improved.

Title: Heat exchanging device
Inventor: UMEMURA HIROYUKI
IPC: F28F1/32
Filed: 1985-05-24
Abstract: PURPOSE:To increase the movement of fluid between neighboring flow paths and permit highly efficient heat transfer by a method wherein the area ratio of a through-hole with respect to first heat transfer body is changed in accordance with the relative position of the hole with respect to second heat transfer body. CONSTITUTION:When the flow amount and total pressure of fluid, flowing through an expanded flow path and a narrowed flow path, are supposed to be constant, a pressure difference is generated between one surface side and the other surface side of the same part of a fin 1, bent so as to have truncated wavy form, suction and blow-out of the fluid are realized through the through-hole 2 to obtain good heat transfer promoting effect and a boundary layer is re-developed in the heat transfer surface at the blow-out section starting from the bent section of the fine 1, therefore,, the heat transfer promoting effect, having the same degree substantially as the same in the suction section, is obtained. When the fluids flowing through the expanded and narrowed flow paths, collide against a pipe 3, stream at the back side of the pipe 3 is stagnated, a dead water area 6 is generated and heat transfer characteristic therein is deteriorated extremely as compared with the same in the other area. Accordingly, the number of through-holes 2 in the part corresponding to the dead water area 6 is increased to increase the pressure difference between neighboring expanded and narrowed flow paths and promote the movement of the fluid whereby more prominent heat transfer characteristic may be obtained.

Filed: 1995-05-10
Abstract: PURPOSE: To prevent malfunction due to the vibration of an antenna and to improve signal reception state in a step-type tracking when the traveling body turns by rotating the antenna at a rotary angle speed corresponding to the turning angle speed of the traveling body when tracking a satellite. CONSTITUTION: When a signal reception intensity signal LEF1 received by an antenna mounted at a traveling body is smaller than a threshold TH and a level |V| of the turning angular velocity is equal to or more than a threshold ΔV while the traveling body is turning, a value N2 for clocking to generate one pulse is set to a value which is inversely proportional to |V|. A group of drive pulses with a repetition frequency which is proportional to |V| are added to a stepping motor intermittently. The stepping motor finely rotates the antenna in a direction opposite to the turning direction of the traveling body.

Title: Paper feeder
Inventor: TAKANO TOSHIHIRO
IPC: G03G15/00
Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To reduce resistance when recording paper is fed out from a feed paper cassette so as to prevent defective feeding. SOLUTION: A cassette plate 2 on which recording paper P is placed is pushed up by means of a spring. When the recording paper P is discharged by means of paper feed rollers 11, 12, the recording paper P is pushed down by means of the paper feed rollers 11, 12. Although separation gates 9, 10 follow up and lower, their lowering quantities are restricted to a certain fixed extent by means of projection parts 14, 15, and height regulation parts 9e, 10e are separated from the upper face of recording paper P. Then, the recording paper P is guided by means of guide pads 9f, 10f, and deflection can be reduced when the recording paper P is discharged diagonally upward, so that resistance against feeding can be reduced.  When the width between the projection parts 14, 15 is matched with a dimension of thick paper such as a postcard, misfeeding or double feeding of the thick paper such as a postcard especially can be prevented.

This capsule 1 is enclosed in a pressure vessel main body 8 having an optical window and is heated by a jacket 11 to a specified temperature. Observation of the solid to be measured is conducted by a video monitor while a video camera is attached to a stereo-microscope. Then, pressurizing and pressure reducing are repeatedly applied to the capsule 1 so as to determine pressure for the solid to be measured to become stationary in the immersion liquid. A specific volume of the immersion liquid under the temperature and pressure at this time is adopted as a specific volume of the solid to be measured under these temperature and pressure. This operation is applied to plural kinds of immersion liquids different from each other in the specific volume so as to find relationship between temperature/pressure and specific volume of the solid to be measured.

IPC: G01P5/12
Filed: 1981-07-20
Abstract: PURPOSE:To reduce material costs and decrease the amount of dust attachment, by forming the resistor body made of nickel or nickel alloy on the surface of a cylindrical ceramic substrate, providing electrodes and leads on both ends of the substrate, and forming a protecting film of inorganic glass on the surface of the heat sensitive resistor body. CONSTITUTION:On the substrate 9, wherein Al2O3 is sintered with SiO2 and MgO as a sintering assistant, a lead electrode 11 made of 18-8 stainless steel is brazed. Then, nickel resistor wire 8 is wound and spot-welded, glass is applied and burned, and the temperature sensitive resistor body is formed. For example, When the air quantity for an automobile engine is detected, nickel is used as the temperature sensitive resistor material instead of platinum because the temperature difference between the intake air temperature and the temperature sensitive body is about 100-190 deg.C. Therefore the material costs are reduced. Since the glass protecting film is provided, the amount of the dust attachment is decreased, and the stable characteristics are secured.
