Title: Stored program control system exchange
Inventor: HAYASHI HIROYUKI
IPC: H04M3/24
Filed: 1985-02-08
Abstract: PURPOSE:To improve the efficiency of maintenance and management of an exchange by storing an extension accessory function data to an external storage device at each time, reading the extension accessory function data from the external storage device when the extension accessory function data is not guaranteed at the occurrence of a fault in an exchange and resetting the exchange so as to guarantee the extension accessory function data. CONSTITUTION:A processor CPU supervises a time of system, and when the time is coincident with time information stored in advance in a storage device M, an extension accessory function data stored in an extension accessory function data storage section D is read and stored in an external storage device FL. The processing is executed automatically and repetitively by the processor CPU at all times. Then if an error takes place in an exchange and the content of the extension accessory function data storage section D is not guaranteed, the processor CPU reads the extension accessory function data stored earlier than that in the external storage device FL and sets the data to the storage D. Thus, the guarantee of the extension accessory function data is attained.

Title: Interphone
Inventor: ABIKO TOSHIO
IPC: H04M9/10
Filed: 1983-02-15
Abstract: PURPOSE:To realize simultaneous communication by providing a means shifting a sound frequency between a microphone and a speaker. CONSTITUTION:A signal from the microphone is sampled by an A/D converter 12 by using a signal in 8kHz obtained from 1/9 frequency-division of a clock signal in 72kHz. A CPU14 counts an output signal of a zero cross detecting circuit 17 and writes a data for 10 waves' share to a memory 131. When the write to the memory 131 is finished, the write to the next memory 132 is performed. While the memory 132 is written, the memory 131 is read by using a signal in 7.2kHz obtained from 1/10 frequency-division of a clock signal. Since the spectrum of the sound frequency from the microphone is transited and the signal is outputted from a speaker, howling is prevented.

Title: Recording method by ink jet recorder and recording head adapted to the method
Inventor: SAKAI MARI
IPC: B41J2/14
Filed: 1997-01-22
Abstract: PROBLEM TO BE SOLVED: To reduce influence of an ink viscosity as much as possible and to discharge ink droplet of small ink amount at a flying speed adapted to printing by selectively pressurizing only a central region of a meniscus. SOLUTION: A piezoelectric vibrator is abruptly charged, and contracted at a predetermined speed. Thus, a pressure generating chamber is quickly expanded, and a central region mc of a meniscus steady near a nozzle opening 20 is rapidly drawn relatively largely to the chamber side. At a stage that the region mc of the meniscus is largely drawn to the chamber side, the vibrator is discharged, abruptly elongated at a predetermined speed to contract the chamber at a predetermined speed. A flow or inertial flow of ink pressurized by the chamber due to the contraction of the chamber is concentrically operated at the region mc of the meniscus near the chamber side, and hence only the region mc of the meniscus is selectively urged at a very high speed.

Abstract: PURPOSE:To improve peeling property between a photosensitive element and a dye fixing element by incorporating an oily component to the photosensitive element or the dye fixing element in the titled method contacting the photosensitive element with the dye fixing element thereby transferring the diffusive dye contd. in the photosensitive element to the dye fixing element. CONSTITUTION:A silver halide and a dye donative substance capable of forming or releasing a diffusive dye are incorporated into the photosensitive element. The photosensitive element is image-wisely exposed, followed by developing it. Subsequently, the photosensitive element is contacted with the dye fixing element, whereby the diffusive dye which is formed or released in the photosensitive element, is transferred to the dye fixing layer of the dye fixing element and fixed. The image is formed on the dye fixing element by peeling the photosensitive element from the dye fixing element. The oily component is incorporated into at least one layer of the layers which constitutes the photosensitive element and the dye fixing element. The oily component is exemplified by preferably silicone oil having 140 deg.C b.p. Thus, as the oily component is incorporated in the constituting layer, the peeling property between the photosensitive element and the fixing element is improved after transferring the dye, and a roughness of the film surface can be reduced.
