Title: Muting circuit
Inventor: SHIBUYA HIROTO
IPC: H03G3/34
Filed: 1981-04-16
Abstract: PURPOSE:To eliminate a shock sound and to obtain the substantially-necessary amount of muting by constituting the variable impedance part of a muting circuit by using the 1st and 2nd circuit parts composed of transistor (TR) of complementary polarities whose emitters are connected directly. CONSTITUTION:An input signal ei from a signal source 24 is transferred as an output signal e0 to an output terminal through a coupling capacitor 23 and a resistance 22. A muting signal is inputted from a terminal 25 to generate a muting control current IM by TRs 12 and 14 and a resistance 16, and thus while a current IM flows through TRs 11 and 18 constituting a current mirror circuit, the current IM flows TRs 19 and 20 forming a current mirror circuit. At this time, a voltage at a terminal 26 is biased from an earth point by the voltage value 1/2VCC of a constant voltage source 31, and then is raised by a VBE through a TR13; and it is lowered by the VBE through the TR19 to be held a half as high as the VCC, so that muting operation generates no switching noise.

Title: Gripper for packaging bag in packaging machine
Inventor: SHIMIZU KEIICHI
IPC: B65B43/54
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To allow a packaging bag to be reliably held in a stable posture even if a weight of contents to be bagged is large by coupling a movable claw piece with one of parallel links by a link mechanism comprising a first toggle joint and a second toggle joint. SOLUTION: When an intermittently rotating body 1 of a packaging machine stops at a supply station for supplying a packaging bag B, an open/close rod operates a release control piece to press an engaging roller 30 against elastic force of a compressive spring 22, and a first toggle joint T1 and a second toggle joint T2 are released from a toggled state so that a movable claw piece 12 comes away from a receive face 11 for receiving or releasing the packaging bag B. When the packaging bag B is supplied, the open/close rod moves the release control piece away from the engaging roller 30, an open/close control lever 20 is restored by elastic force of the compressive spring 22, and the movable claw piece 12 presses a side rim of the packaging bag B with strong force due to synergistic function of the two toggle joints T1 , T2 .

Abstract: PURPOSE:To provide a transformer placed close to a plurality of insulating conductors, which operates stably even in high frequency and which can be shielded with a simple magnetic sheet, by arranging a thin magnetic sheet and making part of the conductors a primary conductor and the rest a secondary conductor. CONSTITUTION:Two conductors C11 and C12 are placed in proximity to each other in parallel and the two are wound together in a planar manner. Conductors C11 and C12 are of approximately the same length and of approximately the same diameter, and part of the conductors are used as a primary conductor while the remaining part makes for a secondary conductor. A magnetic material Mm through coating or the like of magnetic powder is arranged on the surface of the conductors C to form a shield type air-core transformer. Also, a thin shield type air-core transformer is used for equipment such as a personal computer to enable personal equipment to be made in a thin form. Since this makes it possible for stable operation even in high frequency and shielding in a simple magnetic sheet, it can be placed directly near other parts. As a result, it can be placed with a high degree of freedom and equipment can be made small and thin.

IPC: G01G19/44
Filed: 1980-05-06
Abstract: PURPOSE:To miniaturize the device and to facilitate a read by obtaining a weight value through conversion by subtracting an electric output obtained in an unloaded state from that proportional to a weight in a loaded state. CONSTITUTION:When a man is on a weighing machine, host switch 10b is pressed to turn on, and DC/DC converter 10d is put in operation to supply electric power from circuit 10 to respective circuits. Simultaneously, the electrostatic capacity of sensor 5 in the weighing machine varies and the oscillation frequency of corresponding oscillator 6 is determined to send the oscillation frequency, proportional to the weight to microcomputer 8 via frequency divider 7. Once the stabilization of the weight is detected, its oscillation frequency fw is stored in RAM and buzzer 9 in operation. Then, when the man gets off the weighing machine, the unloaded state is detected and frequency f0 is read to convert fw-f0 into a loaded value, which is displayed 3. Thus, the device is miniaturized and reading operation is facilitated.

Title: Power system simulating method
Inventor: OTA YUJI
IPC: H02J3/00
Filed: 1990-03-09
Abstract: PURPOSE:To shorten sequence simulation time by maximizing the advance width of internal time of relay simulation in a power system simulating method for training workers in a control station. CONSTITUTION:Operational simulation of a relay is carried out based on fault calculation in the simulation of power system. Internal time is advanced if CB trip does not exist in the sequence simulation step. The advance width is set at the minimum value of a plurality of timers. If '1s' are outputted from all units 18-20, for example, signals are transmitted from the outputs on the block diagram to timers 21, 22 thus driving the timers 21, 22. Values of the timers 21, 22 are compared each other, where the larger one is referred to TL and the smaller one is referred to TS. The advance width is set at TS in the sequence simulation, then an advance is made by TL-TS and reaches to CB trip through a loop thus ending relay simulation.
