Title: Oscillation device
Inventor: KOTABE MITSUHO
IPC: H03L7/24
Filed: 1978-06-23
Abstract: PURPOSE:To control the charge and discharge of the capacitor in the time constant circuit deciding the oscillation phase of the sag/tension oscillation circuit via the 1st and 2nd transistors controlling the conduction in synchronization with the AC power supply, by connecting the sag/tension oscillation circuit to the smoothing DC power supply. CONSTITUTION:The smoothing DC voltage is applied to the gate of PUT30, and the overlap voltage of capacitor 29 which is charged via Tr28 or resistance 32 is applied to the anode. When the potential of the anode reaches the fixed level to the gate potential, PUT30 conducts and the pulse is delivered from pulse transfomrer 31. Waveform (b) is applied to the base of Tr33 to repeat the conduction and nonconduction like waveform (c). As shown by waveform (d), Tr37 becomes nonconductive and conductive when Tr33 is conductive and nonconductive respectively. Capacitor 29 is short-circuited when Tr37 conducts, and capacitor 29 performs discharge like waveform (e). And the charging is started with every half-cycle of AC power supply 20 to switch on PUT with the fixed phase.

Title: Reinforcing method for connected part of optical fiber
Inventor: MURATA NORIO
IPC: G02B6/24
Filed: 1981-05-21
Abstract: PURPOSE:To increase the degree of reinforcement and the weather resistance, by coating the connected part of an optical fiber with an adhesive material melted by heat  and using a heat shrinkable tube containing a fiber material having strength, a high  elastic modulus and a low thermal expansion coefficient buried at the outer circumference. CONSTITUTION:A plastic coat layer 2 is removed at the connected part of an optical  fiber 1, and the core wires 3 of the optical fibers to be connected to each other are set  opposite to each other at the connected part. A tube 4 made of a graft-modified material of an ethylene-ethyl acrylate copolymer, for instance, is loaded to cover over the  wires 3 and the layer 2 at both ends of the connected part. A heat shrinkable tube 6  to which the carbon fibers 5, for example, are buried equidistantly toward the outer  circumference and in the axial direction is set at the outer circumference of the tube 4. Such reinforcing member is heated by means of an electric heater, burner, hot gun, etc.  Thus the tube 6 shrinks toward the diameter, and at the same time the tube 4 is also  melted. Then the wire 3, the layer 2 and each reinforcing member are adhered together into a body. In such a way, the strength of the reinforcing member is increased, and  the breakdown of the wire 3 can be prevented from the expansion/shrinkage caused by  the temperature change.

Title: Burglar alarm device for device provided with door
Inventor: FUKUDA ICHIRO
IPC: G07F9/10
Filed: 1992-02-28
Abstract: PURPOSE:To properly detect abnormality and to generate an alarm by generating an abnormal signal in response to the detection of abnormal oscillation based upon an output from an oscillation detecting means and generating an alarm signal in accordance with the abnormal signal. CONSTITUTION:An output from an oscillation sensor 6 is applied to a smoothing circuit 8 through an amplifier 7. The circuit 8 smooths the oscillation signal detected by the sensor 6 and generates a DC signal corresponding to the value of an oscillation level. The output of the circuit 8 is impressed on the base of a transistor(TR) 9 whose emitter is grounded. When no oscillation is detected by the sensor 6 or the level of detected oscillation is low, the TR 9 is not turned on and the output of the collector is held at a high level. When the level of oscillation detected by the sensor 6 is more than a prescribed level, the TR 9 is turned on and the collector output is dropped to a low level. Consequently, an abnormal signal indicating the detection of abnormal oscillation is generated.

IPC: G01S7/32
Filed: 1986-03-31
Abstract: PURPOSE:To greatly improve clutter elimination performance by adding a means which calculates a convergence constant used in a load calculating means by using an input signal and adjusting the convergence constant corresponding to variation in the statistical characteristics of the input signal. CONSTITUTION:The convergence constant calculating means 6 stores all input signal with range pin number 1-k-1 equivalently and uses the reciprocal number of the mean weighting value of the input signal electric power to generate the convergence constant muk-1 required to generate a load ak corresponding to a range pin number k. A load calculating means 5 calculates the load by a specific equation by using the convergence constant muk found by the convergence constant calculating means 6. Consequently, the estimation accuracy of the load is maintained irrelevantly to the statistical characteristics of the input signals.

Abstract: PURPOSE:To allow smooth replacement of an electric cell in a minimum space without the erasure of stored information from a semiconductor memory by providing at least two cell contacts and creating a state where a new electric cell and an existing electric cell are connected in parallel when these cells are exchanged in a push-out manner. CONSTITUTION:If an new electric cell 2 is inserted, as a replacement, in a cell insertion aperture 3 of a memory card 1, it is brought into contact with the first + and - electrode contacts 6, 6' for a cell. On the other hand, an existing electric cell is connected to the second + and - electrode contacts for a cell and both cells are placed in parallel. At the same time, the same voltage as applied in the single-cell case is applied to a memory chip 10 and thereby the information of a pixel signal stored is retained. If the new electric cell 2 is pushed through the insertion port, the existing cell 4 is crowed out to a cell delivery aperture 5, and the first + and - electrode contacts 6, 6' and the second + and - electrode contacts 7, 7' are connected to only the new cell 2. Thus the existing cell 4 is easily delivered through the delivery aperture 5. After the delivery, the cell insertion aperture 3 and the cell delivery aperture 5 are covered with an electric cell lid respectively to fix the cell 2.

Moreover, an actuator control part 13 drives a motor 14 and a solenoid valve 15 and controls valve opening of a throttle valve for feedback to the desired throttle opening, and it also drives the solenoid valve 15, thereby controlling brake fluid pressure for feedback to the desired brake fluid pressure. In this case, a time variation in acceleration is calculated, and when this time variation is out of the specified range, the specified control rule is corrected. With this constitution, such a control rule as making proper responsiveness obtainable is thus secured.
