Inventor: OKADO KENJI
IPC: G03G9/09
Filed: 1983-07-22
Abstract: PURPOSE:To fully cover the tone of a magnetic powder, enrich a toner hue, improve fixability, elevate image density, and reduce fog by using a magnetic powder having a specified surface area. CONSTITUTION:A magnetic color toner contains a magnetic powder having a BET specific suface area of 0.3-6m<2>/g measured by N2 adsorption method in an amt. of 20-120pts.wt. per 100pts.wt. of a binder resin, and 5-60 titanium white.

IPC: H04B10/116
Filed: 1995-05-31
Abstract: PURPOSE: To realize prevention of leakage of communication security and maintenance of the operating environment when the optical space transmitter is used by using an infrared ray as its light source. CONSTITUTION: The system is a LAN operated indoors where an information terminal equipment 10 is linked via the optical space transmitter 1 using an infrared ray whose wavelength is 1.4μm or over or between 1.4-1.8μm as a light source. The signal light L1 emitted from the optical space transmitter 1 is diffused and reflected on a ceiling 12 or a wall 13 or the like and made incident onto other optical space transmitter. Through the constitution above, the signal light L1 may be leaked externally through a transparent part in terms of an infrared ray, but the part is covered with a shield member 5 made of a material transparent to a visual light but opaque to the light whose wavelength is 1.4μm or over or between 1.4-1.8μm.  Thus, the leakage of the signal light L1 is prevented to secure communication security and incidence of an external light L3 in the visual range into a room is made possible to maintain the indoor environmental sanitation.

IPC: H01L21/205
Filed: 1988-05-31
Abstract: PURPOSE:To make it possible to leave a single crystal GaAs layer on an Si substrate only by a method wherein an NiSi film is selectively formed on an Si substrate, and after the GaAs layer has been formed on the NiSi film, the GaAs layer on the NiSi film is selectively removed. CONSTITUTION:An NiSi film 3 is formed on an Si substrate 1, then after a GaAs layer 5 has been formed on the Si substrate 1 and the NiSi film 3, the GaAs layer 5 on the NiSi film is selectively removed. Said GaAs layer 5 becomes single crystal on the Si substrate 1 by hetero-epitaxial growth, its adhesive property with the Si substrate 1 is excellent, but it becomes polycrystal on the NiSi film 3, and its adhesive property with the NiSi film 3 is poor. Accordingly, the GaAs layer 5 only on the NiSi film 3, having poor adhesive property with the lower layer, can be selectively removed. As a result, the single crystal GaAs layer 5 on the substrate 1 can be heteroepitaxially grown selectively.

Abstract: PROBLEM TO BE SOLVED: To reduce the erroneous recognition of the voice of a driver without using a voice action button by setting a voice recognition section to a functional state from the judgment result of a voice action start judging means recognizing only the word corresponding to the action start of a user. SOLUTION: When the power switch of an on-vehicle voice recognition device is turned on, the interface section 22 of a voice recognition synthesizing device 2 monitors the utterance of specific voice via a voice action start dictionary and switches the dictionary used by a voice recognition process section to a voice action dictionary when it confirms the utterance of the specific voice. A voice recognition process is started, and voice recognition is made when a user takes a voice action. If there is a high possibility that the recognized voice is based on noise, the process is terminated. If not, the navigation functional content to be processed is judged based on the recognized voice content, and the navigation function to be processed is implemented.

Title: Direction change-over valve
Inventor: MIYAKE MEGUMI
IPC: F16K11/07
Filed: 1979-10-17
Abstract: PURPOSE: To simplify the circuit construction and reduce the pressure loss in the circuit of a captioned valve by providing a pressure chamber to give a pushing force to a spool valve so that the difference between fluid pressures in the upper and the down stream of a pressure reduction valve may be at a fixed level corresponding to the operational force of the direction change-over valve.  
     CONSTITUTION: When the load to an actuator 7 is increased as the actuator 7 is operating in the direction of an arrow A by a fixed speed, the load pressure is given to a bridge 17 via a load passage 14a. Thereby, the current from a chamber 38b of a pilot part 11b to the bridge passage 17 is reduced. Consequently, since the fluid pressure in the chamber 38b is brought to the equivalent value to the load pressure, the pushing force working to a spool valve 12 is increased to work to the right by the increased portion of the fluid pressure in the chamber 38b. Large diameter parts 25a and 26 of the spool valve 12 increase the throttling amount among circular grooves 20a, 21, and 20b, to increase the fluid pressure in a supply passage 16. In this construction, the pressure difference between the upper and the down stream of a valve 18d in a pressure reduction valve 18 is kept at a fixed level to correspond to the pilot fluid pressure.

Title: Liquid crystal display element
Inventor: WATANABE TOSHIO
IPC: G02F1/133
Filed: 1988-06-01
Abstract: PURPOSE:To prevent the generation of an unpacked part with a temp. change and a change in an inter-substrate spacing by providing a buffer chamber to a region exclusive of an effective display region by partition with sealing materials. CONSTITUTION:A thermosetting epoxy adhesive agent is used as an outer circumferential seal 10 and sheet glass having 1.1mm thickness is used as upper and lower substrates 11. Glass fibers having 10mum fiber length and 2.5mum diameter are used as spacers 13 for controlling a gap and oriented films 15 adhered with a resin 14 for inner adhesion are formed of polyimide and are subjected to a rubbing treatment, by which the films are subjected to a uniaxial orientation treatment in a direction 25 and the layer direction of a ferroelectric liquid crystal 18 is formed in the direction 22. The display part 20 and the buffer region 21 are partitioned by the seals 17. The volume increasing part of the liquid crystal 18 does not affect the display part 20 near the upper limit of an operating temp. range as the region 21 swells. The uniform gap control is thus attained. The liquid crystal sealed excessively in the region 21 shrinks near the lower limit of the operating temp. The generation of the unpacked part and the change in the inter-substrate spacing are thus prevented.

Title: Smoothing circuit
Inventor: OHASHI YASUO
IPC: H02M7/06
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To obtain a current waveform having its peak at the left end from the output terminal of a rectifier circuit by causing a capacitor to discharge the electric charges charging the capacitor by controlling the turning-on of a switching means based on the voltage difference between the output voltage of the rectifier circuit and a reference voltage. SOLUTION: When the voltage difference between the output voltage of a rectifier circuit 2 and a reference voltage exceeds a trigger voltage in such a state that the charging voltage of a capacitor 16 is higher than the output voltage of the circuit 2, the thyristor 17 of a switching means is turned on. Therefore, the electric charges charging the capacitor 16 are discharged through the thyristor 17. Consequently, the peak of the waveform of the output current of the rectifier circuit 2 flowing to the output terminal of the circuit 2 is formed at the left end of the waveform. Since the above-mentioned operations are repeated thereafter, the obtained current waveform and harmonic current can be made equal to or lower than the standard value specified by Class A of the guide line based on IFC 1000-3-2ni.

Filed: 1985-06-21
Abstract: PURPOSE:To decrease propagation of an error by using an address count-up address without using a synchronous address when the continuity of the synchronous address with a just preceding content is lost and it is the error only once. CONSTITUTION:The synchronous address 21 read by a synchronizing signal is compared with a value added by one block to a count of a preceding clock at an adder 24 by a comparator 25. When they are equal as the result of comparison, the content of the synchronous address is loaded to a counter 10. When the result of comparison is equal at the preceding block and different in this case, the counter 10 does not load the synchronous address and the block content counted up automatically is outputted. When the synchronous address is '3' as B shown in figure and the counted-up value is '5', for example, the comparator 25 outputs a dissident signal '1'.
