Title: Facsimile adaptor device
Inventor: MIYAMUNE KIYOSHI
IPC: H04N1/00
Filed: 1990-05-21
Abstract: PURPOSE:To eliminate the need for a manual changeover switch by discriminating whether a facsimile equipment of its own station is used in the facsimile mode or in the scanner mode depending on a dial signal. CONSTITUTION:An adaptor 1 dials a telephone number of an external facsimile equipment to fetch a dial signal to a fetch section 11B, an analysis section 13 decodes a dial number, and a discrimination section 14 discriminates whether a connection destination is a personal computer connecting to the adaptor 1 or an external facsimile equipment. Thus, the adaptor 1 fetches a dial signal from the facsimile equipment of its own station to analyze the content and discriminates whether the mode is the scanner mode or the facsimile mode depending on the analyzed result. In the case of the scanner mode, the facsimile equipment of its own station is connected to the personal computer and in the case of the facsimile mode, the facsimile equipment of its own station is connected to a telephone line. Thus, the manual switch for the changeover is not required.

Title: Structure for installing vibrating body of vibration control device
Inventor: SHIMODA SADAKI
IPC: F16F13/00
Filed: 1992-04-22
Abstract: PURPOSE:To facilitate assembling of mounting bracket and prevent generation of engine noise. CONSTITUTION:Stopper rubber layers 76, 76 of predetermined thickness are integrally joined and formed on the surfaces of the outer periphery of the end portion 71 of a mounting bracket 7 which face the support leg of a vibration control device and the bottom wall of a holder, respectively.

Title: Liquid level meter
Inventor: UEDA TOSHITSUGU
IPC: G01F23/296
Filed: 1978-10-24
Abstract: PURPOSE:To simplify the constitution and increase the reliability of the liquid level meter by measuring the liquid level based on the propagation time of the ultrasonic wave propagating in the magnetic distortion line. CONSTITUTION:With output of the exciting pulse with fixed cycle from exciting pulse generator OS, current i2 flows to support part 2 via power transmission transformer 6. Current i2 then flows to magnetic distortion line 1. As a result, current i3 flows to secondary coil 32 of transformer 30 which shifts up and down along with float 3. Current i3 flows to exciting coil 40 in the form of the exciting pulse signal to generate the ultrasonic signal at line 1. At the same time, the exciting pulse given from generator OS sets the FF. With application of the exciting pulse to transformer 6, the ultrasonic signal is produced to line 1 at the position of coil 40 and propagates the line 1 to be received at reception means 5. Signal e obtained through means 5 resets the FF. As a result, the pulse featuring the time duration from set to reset is delivered from the FF. and the time of this pulse period is counted by counter CU.
