IPC: B41J35/10
Filed: 1980-09-30
Abstract: PURPOSE: To facilitate accurate setting of the printing position with a light and operation by performing a printing in such a manner that no correction ribbon follows the lifting of print ribbons.  
     CONSTITUTION: While the excitation of an electromagnetic device 12 is released, an electromagnetic device 6 alone is excited. At this point, an oscillating member 7 is retracted by a changing force of a spring body ignoring a collision with a regulating member 10 until a projection 7b thereof comes off a recess. So, the oscillating member 7 does not turn free from displacement of a lift cam body 4 from the position as indicated by the solid line to the position as incidated by the dotted chain line turning counterclockwise. Therefore, an engaging member 11, a rotary member 13 and a correction ribbon carrier frame 2 do not turn. However, a ribbon cassette carrier frame 3 displaces from the position as indicated by the solid line to the position as indicated by the dotted chain line turning clockwise as an engaging pin 3b rises along an inclined surface 4b1 of a cam body 4b, displacing from the position as indicated by the solid line to the position as indicated by the dotted chain line. Thus, a print ribbon is lifted and set at the given printing position of a type body.

Title: Battery saving system of radio relay system
Inventor: OOTSUKA SHIGERU
IPC: H04B7/15
Filed: 1983-07-25
Abstract: PURPOSE:To improve the power saving effect by stopping the battery saving operation when a line is established among a base station, a repeater station, and a terminal station and performing the battery saving operation in repeater stations and terminal stations which do not contribute to line establishment. CONSTITUTION:A base station MS1 communicates with terminal stations TSs 4, 61, and 62 through repeater stations RSs 2 and 3 in the time division multi- access system. In the initial state, each station supplies power to operate a transmitter and receiver. The MS1 transmits a synchronizing signal BS-SYNC for battery saving at a certain period. When detecting this synchronizing signal, each of repeater stations and terminal stations turns off the power source for a certain time and turns on the power source again before reception of the next synchronizing signal and repeats this operation to reduce the power consumption. For example, in case of a call to the MS1 to the TS61, the MS1 transmits a start pattern signal to the RS2 and the TS61 while the RS2 and the TS61 turn on power sources again, and power sources of the RS2 and the TS61 are stopped from turning off, but the MS1 transmits the signal BS-SYNC to the RS3 and TSs 4 and 62 to continue the battery saving operation there.

Title: Piston shock absorber of pressure accumulator
Inventor: NISHIMURA SEIICHI
IPC: F15B1/04
Filed: 1977-11-10
Abstract: PURPOSE: To reduce bottom impact and eliminate vibration, by reducing the dropping speed of a piston due to a load of water pressure which is generated through limited amount of exhaust when a weight drops to a certain height.  
     CONSTITUTION: When the use of pressure water increases and a piston 5 drops to a preset height H, a valve body 11 is pressed to a valve seat 13 to close a port 14. Then pressure water in a cylinder 6 flows out through an orifice 15, which reduces the amount of exhaust and generates load of water pressure in the cylinder 6 and a large force works for reducing the drop of piston 5 to reduce its dropping speed. As the piston 5 continues to drop, its lower end collides with the bottom of the cylinder 6 through the valve body 11. Since it drops being reduced its speed in proportion to the amount of pressure water flowing out through the orifice 15, no impact is generated at the time of contact.

Title: Electromagnetic type speaker
Inventor: MURAKAMI FUMIKAZU
IPC: H04R13/02
Filed: 1979-10-19
Abstract: PURPOSE:To reduce the diameter of electromagnetic type speaker, without incurring the lowering in resonant frequency and sound pressure, by inserting a spring member bending broadwise the moving iron piece between the surrounding of moving iron piece and the plate to support the moving iron piece. CONSTITUTION:Magnetic flux by a magnet 4 flows through the plate 2, magnetic core 1 and moving iron piece 6 to produce a high magnetic flux density at magnetic air gap between the moving iron piece 6 and the magnetic core 1. Further, when a signal current flows to a coil, the magnetic flux produced flows to a loop almost the same as the magnetic flux by the magnet 4 and the magnetic flux of magnetic air gap is changed, to oscillate the moving iron piece 6. Since the moving iron piece 6 is supported with a spring support 8, the moving iron piece 6 oscillates close almost to a piston movement. Further, since the moving iron piece 6 covers the magnet 4, leakage of magnetism is less and the magnetic flux in the magnetic air gap is increased.

Filed: 1986-06-11
Abstract: PURPOSE:To eliminate the asymmetry of step response, by adding a logarithm converter in the feedback loop of AGC. CONSTITUTION:An input signal is attenuated by a step attenuator 1 so as not to be satuated at an A/D converter 2. The control of the step attenuator 1 is performed by the output of a register 6 scaled to F/N at the second scaler 3b. The output of the A/D converter 2 is scaled by the first scaler 3a, and only an amplitude component is taken out by an absolute value circuit 4. The logarithm of the amplitude component is outputted by a logarithm converter 8, and a threshold constant lnK is subtracted by a subtractor 5, and a differential output is sent to an accumulator circuit consisting of an adder 7, and the register 6, and is integrated until the output of the A/D convert 2 arrives at a certain level. Thus, an AGC feedback characteristic is linearized, and the asymmetry of the step response can be eliminated.
