Title: Recording head
Inventor: MORI AKIHIRO
IPC: B41J2/325
Filed: 1987-05-14
Abstract: PURPOSE:To improve the supply of ink, thereby make realization of stable recording possible by providing a housing in such a manner that it is connected to a substrate having an ink passage hole which runs through a heat generating element, and an ink stirring means to be stored in the housing. CONSTITUTION:A heat generating element 7 which generates heat selectively in response to an image signal, a substrate 4 having an ink passage hole 8 running through the heat generating element 7, a housing 2 permitting ink storage which is connected to the substrate 4 and an ink stirring roller 13 installed in the housing 2 constitute the subject recording head. When the stirring roller 13 with a spiral groove engraved on the surface is rotated by an external drive means, the viscosity of thermomelting ink 3 to be filled in the housing 2 of the recording head 1 reduces. Consequently, the fluidity of ink is improved resulting in the smooth supply of ink into the ink passage hole 8. Thus stable recording can be obtained and also bubbles contained in the ink 3 removed, which enables a further stable, satisfactory image to be obtained.

Title: Semiconductor integrated circuit
Inventor: OWADA NAOMI
IPC: H01L27/04
Filed: 1988-05-11
Abstract: PURPOSE:To enable densification by burying a high resistance polycrystal silicon area in height up to semiconductor substrate surface between buried layers right below each of the SBD (anode) area and the base area of a flip flop circuit by a vertical bipolar transistor. CONSTITUTION:A high resistance polycrystal silicon area 6 reaching a third buried layer 10 from the surface of a P type semiconductor substrate 1 is provided in each complex element. In this case, since the resistance of an epitaxial layer 3 is interrupted due to a high resistance polycrystal silicon area 12, series resistance Rd can be determined by a second buried layer 2, and the layer resistance of the third buried layer 10 can be set rather higher. By dividing the epitaxial layer 3 vertically this way, the area required for series resistance connected serially with SBD can be made small, and densification is made possible.

Title: Monitor system for out of speech zone/battery voltage for cordless telephone system
Inventor: SHINOHARA SHINICHI
IPC: H04W88/02
Filed: 1992-05-08
Abstract: PURPOSE:To simplify the setting of a criterion of the movement of a cordless telephone set to the outside of its speech zone and a criterion of a battery voltage drop. CONSTITUTION:A reference radio wave is sent from a reference radio wave generator 30 to a radio transmission reception section 3 and an electric field strength outputted from the radio transmission reception section 3 to a lead L1 is stored in a nonvolatile memory 4 as a criterion of movement to outside of its speech zone. Moreover, a reference voltage is impressed from a reference voltage generator 40 to a power supply path L2 and a voltage appearing at the power supply path L2 is stored in the same memory 4 as a voltage drop criterion. Since the setting of the criteria is implemented through relevant circuits, each criterion is subject to dispersion in each characteristic of each product, the setting by adjustment of a volume control or the like is not required and the adjustment man-hour is remarkably reduced. Furthermore, since the criteria are stored in terms of digital data, the criteria are not fluctuated due to an environmental change or shock or vibration at transportation and then the reliability is improved.

Title: Floppy disc recorder
Inventor: ARAKI IZUMI
IPC: G11B19/18
Filed: 1984-06-07
Abstract: PURPOSE:To suppress a delay time of a ready signal restoration as less as possible by changing the ready signal depending on the opened and closed clamp mechanism so as to prevent the generation of a write/read error due to mis- operation. CONSTITUTION:If a knob or a door is opened when a device selection signal DS is at an L level, the ready signal LD outputted from a NAND gate 22 with a delay of a time constant Ta of a monostable circuit 17 changes to an H level representing disabled write/read. When the knob or the door is closed in such a state, the signal LD changes to an L level representing the write/read preparation end with a delay of time Tb corresponding to four pulses of an index signal IND. Thus, if the knob or the door is opened in error during write/read of the information to a floppy disc, the signal LD changes immediately to an H level and write/read is stopped.

Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To make possible realizing further higher tone quality than conventional one. SOLUTION: Preceding a run of a movie, the sound data in a movie film sent to a digital signal reproducing device 11 are converted to an electric signal by a photodetector 12. The converted signal is stored in a hard disk device 15 from a film reproducing device 13 through a controller 14. The controller 14 sends a control signal to the film reproducing device 13, a motor drive circuit 17 and the hard disk device 15 based on the time code data related to the sound data together with the regenerative sound data from the film reproducing device 13 to control them. Further, a sound signal is sent from the controller 14 to a speaker 19.  Since the sound data stored in the hard disk device 15 not the sound data from the movie film are read out successively at a real run time, the sound with the high tone quality is reproduced always independently of the number of run times without precise constitution.

Title: Detection circuit of television signal
Inventor: ISOBE MITSUO
IPC: H03L7/08
Filed: 1983-06-28
Abstract: PURPOSE:To make the tuning frequency follow the vidoe IF frequency by changing the tuning frequency with the output of a frequency detection means whose output voltage varies in proportion to the frequency change of a carrier wave signal. CONSTITUTION:The video IF signal of a signal input terminal T1 is supplied to a selection circuit 11 for variable tuning frequency, and the output signal of the circuit 11 is supplied to a PLL2 and a signal input terminal 4a of a circuit 4 respectively. The output voltage of the circuit 4 has an approximately linear change within a variation range of frequency of the video IF signal. The tuning frequency of the circuit 11 has an approximately linear change by the output signal voltage of the circuit 4, and the varying direction is selected so that said tuning frequency is lowered with the rise of voltage. Therefore the relative phase difference between the carrier wave signal supplied to the PLL2 and the carrier wave component of the video IF signal of the terminal T1 is approximately fixed despite the change of frequency of the video IF signal. Furthermore the relative phase difference is also fixed between two input signals of a multiplier 3.
