Title: Structure of accessary mounting device of engine
Inventor: ABE KOJI
IPC: F02B67/00
Filed: 1990-03-15
Abstract: PURPOSE:To reduce vertical vibration of an engine by mounting an accessary so that the accessary serves as a dynamic damper through attaching a mounting bracket to an engine body at the position near the central axis of the vertical mode vibration of the accessary, and in addition, by providing a constraining member at the position near the central axis so as to suppress the forward and backward vibration of the accessary. CONSTITUTION:A mounting bracket 6 is attached to an engine body 2 at the position near the central axis 8 of the vertical mode vibration of an accessary 4. The accessary 4 vibrates in the vertical mode vibration through this mounting bracket 6. Forward and backward mode vibration of the accessary 4 is prevented by providing a constraining member 14 for suppressing the forward and backward mode vibration of the accessary 4. In this case, the vertical mode vibration of the accessary 4 is not suppressed because the constraining member 14 is fixed at the position near the central axis 8 of its vertical mode vibration. Thus, direction of the vibration of the accessary 4 coincides with that of the vertical vibration of the engine body 2. Because the accessary 4 vibrates vertically in an opposite phase with respect to the engine body 2, the accessary 4 can serve as a dynamic damper.

Title: Measurement of level
Inventor: KANAI FUMIAKI
IPC: G01C5/04
Filed: 1989-03-17
Abstract: PURPOSE:To cover a wide measuring range by dividing a measuring range into a plurality of blocks to detect levels at measuring points with a continuous injection of water at each of the blocks. CONSTITUTION:After injection of water into communicating pipes 5 to such an extent as to allow detection of water level with comparison manometers 4, water is injected into a pipeline 2 at a block A. Simultaneously with an output of ON signals from displacement manometers 1 provided at measuring points within the block A, a controller records a water level converted from an output voltage value of a reference manometer 3 on a magnetic disc. Water levels thus obtained correspond to levels at measuring points. Likewise, the controller stores water levels corresponding to levels at measuring points at blocks B-D on the magnetic disc. On the other hand, the controller detects a relative level difference between measuring points where the manometers 4 are set from output voltage values thereof 4 to correct water levels at measuring points stored in the magnetic disc based on the results thereby calculating levels at all measuring points based on the same reference point.

Title: Abbreviated dialing register controller
Inventor: FUJITA HIROSHI
IPC: H04M1/274
Filed: 1986-03-24
Abstract: PURPOSE:To prevent illegal registration of third persons by changing the service function class of an operated telephone set with only a specific dialing operation to register system abbreviated dialing. CONSTITUTION:When the system abbreviated dialing register operation is performed on a telephone set 1, a central controller 5 takes out the service function class of the telephone set 1 from a service function class memory 6. This service function class is compared with contents of a system abbreviated dialing registerable number memory 7. If this comparison results in coincidence, dialing from the telephone set 1 is registered as dial abbreviated dialing. Though this registering is controlled because the comparison does not result in coincidence normally, this control is released by preliminarily determined specific dialing on the telephone 1.

IPC: H04Q11/04
Filed: 1988-03-18
Abstract: PURPOSE:To reduce the quantity of the hardware of a digital telephone exchange system by causing one piece of time division control circuit to simultaneously generate (n) kinds of time division timing signals having different timing. CONSTITUTION:Pulse of a 1st period are generated by means of a counter 201 and inverter 205 and pulses of the 2nd period which is (n) (n=a natural number of >=2) times or more the 1st period are produced by counters 201 and 202, inverter 206, and flip flop 203.

Title: Digital frequency converter
Inventor: MISHINA TAKASHI
IPC: H03K5/00
Filed: 1980-05-20
Abstract: PURPOSE:To extract a difference in frequency between digital input signals easily and securely, by inputting the digital signals, differing in frequency, to an up-down counter and by ANDing among their count values. CONSTITUTION:An up-down counter 5 is applied at input terminals UP and  DOWN with input signals V1 and V2 and its count values A, B, C and D are inputted to an AND circuit 6, which generates an output signal V3. For example, when the variation in pulse level of the signal V1 makes its count value goes up by one or the count value of the signal V2 go down by one, the count values A, B, C, and D are discriminated by the circuit 6. If the counter 5 has four bits, its maximum count value is 2<4>, i.e., 16 and the signal frequency F of the output is (f1-f2)/ 16. Consequently, a difference in frequency between the signals V1 and V2 is extracted easily and securely.
