Abstract: A drive control device and a drive control method for a stepping motor are provided to reduce the number of parts and generation of vibration and noise by a stepping motor. The drive control device controls a drive frequency of the stepping motor according to a measurement value inputted. The drive control device includes storage means for storing the resonance frequency of the stepping motor based on its resonance characteristic as an output-inhibited drive frequency and control means for calculating an instruction angle for operating a needle according to the measurement value, acquiring a first drive frequency of the stepping motor, judging whether the first drive frequency is the output-inhibited drive frequency, and deciding the drive frequency by replacing the first drive frequency with the second drive frequency which is lower than the output-inhibited drive frequency if the first drive frequency is the output-inhibited drive frequency.

Abstract: A pointer measuring instrument capable of indicating “zero” on an indication panel by a pointer even if a play (backlash) is present in gears. The measuring instrument comprises a pointer reference position setting means (7a, 7b) for determining the reference position of the pointer (4). A control means (6) rotates the pointer (4) in the direction toward the reference position when a power supply to a stepping motor (2) is turned on, and performs a first drive for stopping the rotation of the pointer (4) when it receives a pointer reference position arrival signal from the pointer reference position setting means (7a). Then, the control means performs a second drive for moving the pointer (4) by a first angle from the reference position in the reverse direction away from the reference position, and performs a third drive for rotating the gear (3S) of a reduction mechanism (3) on the stepping motor (2) side by a second angle.

Abstract: An image sensor module is composed of a base, a CCD image sensor, a glass plate, and a frame-shaped moisture permeable member. The base has a depressed chip chamber, in which the CCD image sensor is contained. Top and under surfaces of the moisture permeable member are provided with adhesive layers. The base and the glass plate are attached above and below the moisture permeable member through the adhesive layers, and the chip chamber is sealed. The moisture permeable member has the property to block liquid water while transmit water vapor, and releases the water vapor produced by the heat of the CCD image sensor from the inside to the outside of the chip chamber.

Abstract: A brush holding apparatus is mounted to an inner wall surface of a rear bracket and a cap mounted to a head portion of a brush holder portion is exposed through an opening in the rear bracket. Brushes are housed inside brush insertion apertures of the brush holder portion and are placed in elastic contact with slip rings by springs. An abrasion detection terminal is insert molded into the brush holder portion, a contact thereof projecting inside one of the brush insertion apertures and coming into contact with the corresponding spring when the brushes are abraded by a predetermined amount.

Abstract: An image sensor module is composed of a base, a CCD image sensor, a glass plate, and a gasket. The base has a chip chamber with an opening, in which the CCD image sensor is contained. The glass plate is bonded by an adhesive layer to a top surface of the base, and covers the opening. The gasket is held between the base and the glass plate. The gasket is disposed inside the adhesive layer and seals the chip chamber tightly, so that moisture in the surrounding air does not enter the chip chamber.

Abstract: An end-to-end delay acquisition unit in a radio terminal measures end-to-end delay time, which is the delay time required for end-to-end transmission and reception, by using PING packets in an IP network or the time stamp function of RTCP during VoIP communication. An activation period modification determination module that is provided in the radio terminal modifies the activation period of the radio communication module that carries out radio communication such that the end-to-end delay time that has been measured by the end-to-end delay acquisition unit is equal to or less than a standard value that has been stipulated in advance.

Abstract: A speaker system for a vehicle including: a plurality of speaker units which are formed by attaching a speaker to an enclosure and located inside the vehicle, wherein an imaginary sound source is considered in arranging the speaker units inside the vehicle and the minimum resonance frequency of the speaker units is reduced.

Abstract: Straight, nano-scale-order amorphous carbon tubes having a long-term stable ability for storing various kinds of gases and being stable in shape, and a novel process for producing said carbon tubes with high purity, high yield and high mass-productivity are provided. The amorphous nano-scale carbon tubes are prepared by subjecting a heat-decomposable resin having a decomposition temperature of 200 to 900° C. to an excitation treatment in the presence of a metal powder and/or a metal salt, or by subjecting a carbon material containing —C?C— and/or ?C? to a heat-treatment at 3000° C. or lower.
