Title: Electronic buzzer
Inventor: MURAKAMI FUMIKAZU
IPC: G10K9/12
Filed: 1977-12-28
Abstract: PURPOSE: To obtain a miniature and highly-efficient buzzer with its resonance frequency suppressed low by providing the 2nd diaphragm away from the 1st diaphragm with an air chamber interposed and by making use of this resonance frequency.  
     CONSTITUTION: Around magnetic core 2, coil 3 and ring magnet 4 are arranged and flowing an alternating current to coil 3 causes the 1st diaphragm 5 with moving iron 6 anchored to vibrate at a frequency of (f 1 ); and its vibrations allow the 2nd diaphragm 12 via air chamber 13 acting as an air spring to resonate at a frequency of (f 2 ), thereby emitting sound waves into the air. Diaphragm 5 is miniaturized and as its diameter becomes smaller, resonance frequency (f 1 ) rises higher enough to give displeasure, but the thickness and quality of diaphragm 12 are selected with (f 2 ) less than (f 1 ), so that the maximum sound pressure can be obtained at a low frequency. In case of a wrist watch, the inside of air chamber 13 is under an atmosphere invariably although the inside is held airtight by packing 11, so that diaphragm 12 will have no difference in pressure with an atmosphere as the result of variation in temperature. Resonance frequency (f 2 ) therefore varies greatly with temperature.

Title: Discriminating system of momentary trouble
Inventor: ARAI TSUTOMU
IPC: H04B17/00
Filed: 1983-08-30
Abstract: PURPOSE:To reduce burden of a supervisory system by judging it an ordinary trouble when time of trouble or number of times of troubles exceeds a set value within a specified time from occurrence of the trouble, and judging it as a momentary trouble when time of trouble and number of times of troubles is less than a set value within a specified time. CONSTITUTION:Trouble information inputted from a terminal 1 is compared with present state of trouble D1 stored in a memory 3 in a status change detecting section 2, and a trouble occurrence signal phi1 or a trouble restoration signal phi2 is sent to an intensive processing section 4. The intensive processing section 4 collates setting time Ts of a setting section 8 and trouble cumulative time of trouble Tn of a timer 6, and if Ts<Tn, it is judged as an ordinary trouble, and the result K1 of processing is outputted. Further, it collates number of times of setting of the setting section 8 and number of times of occurrence of troubles Cn of a counter 5, and if Ts<Tn, the result K1 is outputted as an ordinary trouble. When Ts, Cs are larger than Tn, Cn, it is judged as momentary trouble and the result K2 of processing is outputted.

Title: Continuous over-aging method for continuously hot aluminum dipped steel sheet
Inventor: IMATOMI HISAO
IPC: C23C2/12
Filed: 1978-12-25
Abstract: PURPOSE: To soften the material of steel sheet which has been continuosly annealed and hot-aluminum dipped so as to improve press moldability, by over-aging the hot- aluminum dipped steel sheet continuously.  
     CONSTITUTION: Steel sheet 4 which has been continuously annealed and hot-Al dipped is harder, and inferior in workability, than the steel sheet having been batch annealed and hot-Al dipped. To soften the former steel sheet, it is rapidly heated in an induction heating zone 1 of a heat treating furnace to a temp. 500W 580°C, and is kept at the temp. within 20 sec. Then it is over-aged by cooling it to 370°C in a controlled cooling zones 2, 3 at a cooling rate as small as not larger than 5°C/sec. Hereby, the steel sheet softens and exhibits excellent workability. Either horizontal or vertical heat treating furnace may produce similar results.

Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To reduce the transient current of a spindle motor during an intermittent reproduction operation. SOLUTION: In this optical disk apparatus, data recorded on an optical disk 101 are temporarily stored in a RAM 106, and the stored data are then read out and used, a reproduction mode in which a remaining amount of data in the RAM 106 is monitored and when the remaining amount of data becomes smaller than a first threshold level, data are reproduced from the optical disk 101 to be stored into the RAM 106, and a pause mode in which when the remaining amount of data exceeds a second threshold level which is larger than the first threshold level, the data reproduction from the optical disk 101 is paused, are provided.
