Title: Structure for fixing brake pad abrasion detector
Inventor: MATSUZAKI YOSHIKI
IPC: F16D66/02
Filed: 1992-09-18
Abstract: PURPOSE:To provide structure for fixing a brake pad abrasion detector where a probe can be stably held even in the case of whole abrasion of a pad by enhancing accuracy of an abrasion detecting position by means of a probe. CONSTITUTION:A probe 5 having a head 5a on a side of a detection end is inserted into a through hole 4 formed on a back plate 2 of a brake pad 1 at the fixing surface of a friction member 3 via a damper member 7 interposed between the probe and the back plate. A seat groove 4a and an expanding portion 5d are formed in an inlet of the through hole 4 and the barrel of the probe, respectively, so that the expanding portion 5d is contained in the seat groove 4a. A clip 6 is fitted to the groove 5c of the barrel of the probe penetrating the through hole 4. The clip is locked at the back surface of the back plate 2, for the purpose of prevention of slip-off of the probe. With this structure, since the front surface of the back plate serves as a positional reference of the probe, variation of a detection position is limited only to a dimensional error of the head of the probe and the damper member. Even if the pad is wholly abraded, it is possible to prevent the probe from slipping off because the expanding portion 5d received in the seat groove 4a remains.

Title: Ionization type smoke sensor
Inventor: SHIMOMURA SHIGEKI
IPC: G01N27/64
Filed: 1989-09-26
Abstract: PURPOSE:To prevent sensitivity from being changed by accumulated dust on a dielectric by alternatively applying positive and negative voltage to be impressed to an ion chamber. CONSTITUTION:A radiation source 8 is provided in a cathode electrode (k) surrounded by an anode electrode (a) and an ion chamber 2 is formed by the anode electrode (a) and the cathode electrode (k). Air is ionized by the radiation source 8 and an ion current flows. However, when smoke flows into the ion chamber 2, the ion current is decreased. By using this fact, the smoke is detected. An output pulse I from an oscillation circuit 1 passes through a capacitor C1 and a resistor R1, becomes alternative positive and negative pulses like II and is impressed to the anode electrode (a). Thus, electric charges, which are formed by the dust accumulated in the ion room 2, to be charged to the capacitor are almost eliminated and the sensitivity of the smoke sensor is kept constant.

Title: Voice output device
Inventor: NAKAMURA YUICHI
IPC: H04R3/02
Filed: 1987-10-05
Abstract: PURPOSE:To improve the degree of freedom in use by adopting the constitution such that an input section, an amplifier section having a variable gain amplifier function and an output section are used so as to attenuate in a very short period as to a signal being discontinuous and consecutive only for a short period thereby preventing howling. CONSTITUTION:A voice signal inputted from a microphone of an input section 1 is band-limited from 200Hz to 6kHz by a band limit circuit and reaches a variable gain amplifier section. The variable gain amplifier section has a characteristic not always being linear and changing periodically while being consecutive from an amplification factor of 0dB to 50dB at 15kHz-20kHz. The voice signal reaching the variable gain amplifier section is at a far low frequency band in comparison with the gain change of the amplifier and recognized as a voice signal as if the maximum amplification factor is constant to human ears. In general, howling is generated from a single frequency component of a very minute voltage among environmental noise in a system having a constant amplification factor in a time nearly 10msec and the howling is attenuated momentarily in the amplifier system and not recognized as the sound.
