Title: Radio wave absorbing wall
Inventor: MORIYAMA YOSHIYUKI
IPC: E04B1/92
Filed: 1992-10-06
Abstract: PURPOSE:To obtain the reflective loss characteristic of a radio wave absorbing wall more than the prescribed value for the entire incident angles of a television radio wave by constituting the radio wave absorbing wall by laminating specific materials in the prescribed order successively from the arrival direction of the radio wave. CONSTITUTION:A ferrite board 13 whose thickness, area, and magnetic permeability are prescribed values is temporarily fixed to a dielectric board 12 whose thickness is 0-50mm (not included 0), whose magnetic permeability is 8-150, and whose area is a prescribed value, with adhesive. Then, the dielectric board with the ferrite plate is adhered to the back face of a granite 11 arranged so that the longitudinal and lateral directions can be a prescribed value, continuously to the magnetic field direction of the radio wave, and uncontinuously through a prescribed interval to an electric field direction. Then, a reflective reinforcing bar 15 is arranged at a prescribed position from the back face of the ferrite board 13, and a concreat 14 is provided, so that the radio wave absorbing wall can be manufactured. Thus, the high reflective loss more than 15dB in 100MHz can be obtained, and the ghost fault of a television can be canceled.

Title: Temperature-measuring device
Inventor: MORII HIROSHI
IPC: G01K7/18
Filed: 1996-11-06
Abstract: PROBLEM TO BE SOLVED: To measure temperature accurately without being affected by a high-frequency magnetic field by a compact and inexpensive device by connecting to a through hole for accommodating a hot wire element and providing a temperature measurement contact accommodation recessed part for accommodating a temperature-measuring contact at a protection pipe. SOLUTION: A protection pipe 25 is extrusion-molded by using a magnetic body ceramic such as nickel-zinc or manganese-zinc based ferrite, and a through hole 28 for accommodating thermoelectric yarn stocks 21 and 22 of - and + polarities is provided. Also, a temperature- measuring contact accommodating recessed part 30 for accommodating a temperature- measuring contact 23 that is formed by making connection to the through holes 28 and 29 and connecting the thermoelectric yarn stocks 21 and 22 is provided at one edge side of the protection pipe 25.  Therefore, since the temperature-measuring contact 23 of a thermoelectric element 24 is accommodated in the temperature-measuring contact accommodating recessed part 30 of the protection pipe 25 made of a magnetic body, a high-frequency magnetic flux that is generated by feeding a high-frequency current to an induction heating coil is centered at the protection pipe 25 that is made of a magnetic body and does not influence the thermoelectric element 24. Also, since it is not necessary to prepare a protection pipe with a long diameter for covering the protection pipe 25, a device can be miniaturized.

Title: Torque detection method for chassis dynamometer
Inventor: FUKUSHIMA HIROKAZU
IPC: G01M17/007
Filed: 1993-10-30
Abstract: PURPOSE:To provide a torque detection method for a chassis dynamometer which enables the detection of a torque generated simply without providing a torque sensor. CONSTITUTION:In a chassis dynamometer which is connected mechanically to a roller 1 on which a drive wheel 2 of a test vehicle is placed and a motor 3, acceleration is determined from the speed of the motor 3 when the coasting operation of the drive wheel 2 is made while no torque is generated from the motor 3. On the other hand, acceleration is determined from the speed of the motor 3 when the coasting operation of the drive wheel 2 is made while a torque is generated from the motor 3. Thus, a torque generated is detected based on both the acceleration and a mechanical inertia value of the roller 1, the motor 3 and a rotating part of the vehicle.

IPC: G03G15/09
Filed: 1991-11-11
Abstract: PURPOSE:To relieve the nonuniformity of the electrostatic charge state of a toner by constituting the developing roller in such a manner that the magnetization layer of a conductive roller is periodically magnetized in the max. curvature direction (direction X) of the peripheral surface so as to attain a positive sine function in the change of a surface magnetic flux density: B(X). CONSTITUTION:This developing roller 1 is constituted by magnetizing the magnetization layer 1B formed on the peripheral surface of the conductive roller 1A. The magnetization is so constituted that the change of the surface magnetic flux density: B(X) in the direction X, i.e., the max. curvature direction of the roller peripheral surface attains substantially the sine function. Namely, the inconstancy in the arranging density of +, - indicating the change rate in the direction X of an N pole and an S pole is indicative of the nonuniformity in the magnetization of the respective pole parts and the surface magnetic flux density: B(X) on the peripheral surface of the magnetized developing roller 1 changes sine-functionally to a wavelength: lambda. The layer thickness of the thin layer of the magnetic developer held on the developing roller 1 is then gently changed at a lambda/2 period with respect to the wavelength: lambda and the fluctuation in the direction X of the electrostatic charge state [q/m] of the toner T is relieved.

Abstract: PURPOSE:To prevent the increase of threshold currents due to reactive currents in an active layer in a coupling region, and to reduce a calorific value by bringing the width of groove bottoms divided into a plurality of oscillation regions and the layer thickness of a second clad layer just under the groove bottoms to specified values respectively. CONSTITUTION:The width W of a groove base is brought to 2.9mum or less, and the layer thickness (t) of a second clad layer just under a groove is determined within a range of 0.16-0.48mum in relation to width W. Mesa sections 26a-26c and grooves 27a, 27b isolating these mesa sections arc formed in such a manner that the second clad layer 24 and a cap layer 25 are laminated successively onto the whole surface on an active layer 23, and both layers 24, 25 are etched selectively. When forward currents are applied among the cap layer 25 on each mesa 26a-26c and a substrate 21, currents concentrate into the active layer 23 just under respective mesa, and laser beams are oscillated. With laser beams output from each oscillation region at that time, phase is synchronized while being mutually coupled, and the laser beams are output as 0 deg. phase mode laser beams. Accordingly, there is no coupling region causing the generating of reactive currents, thus reducing threshold currents by 30% or more.
