Filed: 1994-11-29
Abstract: PURPOSE: To form a dispersion plated film properly controlled in hardness by depositing or codepositing an Ni fine particle and an SiC fine particle at a specific ratio in a hard Ni plated layer or Ni-P plated layer. CONSTITUTION: In the case of executing Ni or Ni-P alloy plating on the surface of a sliding member, since there is a disadvantage that the increased hardness of the plated layer results in the wear of the opposite side member, the Ni particles having 0.5-5μm particle diameter and, >=90% purity or the SiC particles having 1-10μm particle diameter and, >=90% purity are added respecively alone or in combination by the ratio of 0-30% to the Ni plating solution or the Ni-P alloy plating solution or to that further containing phosphate ion or phoshite ion. In the case that the Ni or SiC particles are codeposited, the plating is executed by suspending the Ni particles or the SiC particles in the plating solution regulating Ni/SiC to 0-10. The Ni plated or Ni-P alloy plated layer properly controlled in hardness dispersed with the Ni particle and SiC particle is formed.

Title: Protector for brushless motor
Inventor: KATAGIRI SHINICHIRO
IPC: H02P6/12
Filed: 1996-10-17
Abstract: PROBLEM TO BE SOLVED: To protect the switching elements and the like at an inverter section against damage when rotation of a motor is reversed due to an external force by detecting reversal of rotation of a rotor and deciding that a speed command value is equal to or lower than a set level and then turning all switching elements off based on a stop signal. SOLUTION: Reversal of rotation of a rotor 14 is detected at a reversal detecting section 50. A speed setting section 52 outputs a set speed V0 which is then compared, at a comparing section 54, with a speed command value V1 thus deciding that the speed command value V0 is lower than a set speed. A stop signal S is delivered when the rotor 14 is rotating reversely and the rotational speed command value V1 is lower than the set value V0 in order to turn off all transistors Tr1 -Tr6 . According to the arrangement, an inverter section 12 can be protected by preventing the switching elements and the like from being damaged with a current induced by an external force when rotation of the rotor 14 is reversed.

Title: Automatic sound volume controller for radio machine
Inventor: SUGINO MASAYUKI
IPC: H04M1/60
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for a microphone only for peripheral noise measurement by providing a microphone for sound input and for peripheral noise measurement, measuring peripheral noise and automatically adjusting a sound volume with the result. SOLUTION: At the time of transmission, the sound of an opposite party cannot be received. Thus, the adjustment of the speaker sound volume is not necessary. At the time of reception, a transmission/reception switch part 102 is switched, and it is set to be a reception state. Thus, the sound of the opposite side is transmitted and is outputted form a speaker 106. When peripheral noise is high at that time, it is difficult to hear the sound of the opposite party. Thus, peripheral noise is collected by a microphone 101 which is not used at the time of reception and is measured in a sound volume measuring part 103. Then, the output sound volume of the speaker 106 is adjusted by a sound volume adjusting part 105. Thus, the microphone dedicated only for peripheral noise measurement is eliminated, and the number of parts is reduced and the circuit is simplified.

Title: Filter circuit
Inventor: UEKI KEIJIRO
IPC: H03H11/04
Filed: 1989-11-13
Abstract: PURPOSE:To reduce a required capacitance of a capacitor and to obtain a filter output with high accuracy by utilizing the relation between a base current and an emitter current of transistors(TRs) so as to decrease a charge/discharge current and employing a current mirror circuit so as to control the charge/ discharge of a capacitor. CONSTITUTION:When a 1st TR 10a is turned off and a 2nd TR 10b is turned on in response to an input signal from a signal source 11, a current Io/beta<2> flows to a capacitor 7. In this case, 1st and 2nd current mirror circuits 12, 13 and a 1st current conversion circuit 14 stop the operation, a current does not flow to a TR 14b. In this case, the capacitor 7 charges an input signal. Then in response to the input signal from the signal source 11, the 1st TR 10a is turned on and the 2nd TR 10b is turned off, then the current Io/beta<2> is discharged from the capacitor 7. Since a 3rd current mirror circuit 16 is not working at this moment, no charge current flows to the capacitor 7. Thus, the current charging/ discharging the capacitor is reduced and miniaturization is attained.

Abstract: PROBLEM TO BE SOLVED: To immobilize a radioactive substance in reactor water without increasing a manufacturing cost by forming an oxide film on the outer surface of a cladding tube under conditions where a specific DC voltage is applied in the electrolyte of neutral salt. SOLUTION: A metal frame 13 where a plurality of cladding tubes 1 are arranged is suspended in a conductive anode oxide bath 10 with an electrolyte 11 containing, for example, 0.1% boric acid ammonium.

After the anode oxidation, the cladding tube 1 is withdrawn from the anode oxide bath 10 and is washed before shifting to an edge part cutting process.  Although a part without any oxide film is formed at the upper edge part of the cladding tube 1 by this method, the area of this part is small, so that the function for immobilizing a radioactive substance in a reactor water onto the outer surface of the cladding tube 1 can be obtained fully.
