Patent JP-H1014191-A (JP)
Title: Brushless motor
Inventor: OISHI YASUO
IPC: H02K21/24
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To obtain a brushless motor in which a leakage flux is prevented from having adverse effect on the FG signal of a rotary driving magnet built in a rotor assembly. SOLUTION: A rotary driving magnet 24 having a combination of N and S poles are bonded while being magnetized into 2n (n is a positive integer) along the circumference to the inner circumferential part on the upper surface 21a side of a rotor yoke 21. Every other pole switching part on the outer circumference of the rotary driving magnet 24 is provided with (n) weakly magnetized parts or nonmagnetized parts 24a. Since leakage flux is suppressed at the weakly magnetized part or the nonmagnetized part 24a, adverse effect on the pole of a multipolar magnet 25 for FG is suppressed. Consequently, an FG output signal having uniform and flat waveform is produced from an MR element 16 for reading the pole of the multipolar magnet 25 for FG.

Title: Fuel injection valve
Inventor: NARAHARA YOSHIHIRO
IPC: F02M47/00
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To solve the problem of a conventional fuel injection valve of accumulator type which is large sized and heavy because of long valve body, susceptibleness to fluctuation, and decreased buckling strength resulting from disposing a spring in a nozzle chamber at lower side (injection port side) of the piston. SOLUTION: A spring 10 is disposed in a control chamber 12 at the upper side (injection port side) of a piston 9b. This makes it possible to reduce the whole length of the valve body 9. As the length of the valve body 9 is reduced, it is unlikely to be deformed such as deflection, resulting in simplified manufacturing thereof. The buckling strength of the valve body 9 is also improved.

Title: Numerical controller
Inventor: SHIMA ATSUSHI
IPC: G05B19/4155
Filed: 1986-08-14
Abstract: PURPOSE:To extremely facilitate extraction of a program and to eliminate a miscopy error, etc., by storing the program number of a subroutine from a read-out program and adding the subroutine program to the input program for transfer. CONSTITUTION:When a transfer program number and a transfer command are inputted from an input means 2, a program read output means 3 reads a program of the relevant number to output it to a program transfer means 1. If a subroutine calling command is contained in a block of the read program, a memory means 4 stores successively the command program numbers. When this storage is through, a subroutine program number output device 5 reads the program number out of the means 4 and outputs it to the means 1. The means 3 outputs again the program of the relevant input program number to the means 1. Meanwhile a subroutine calling command is received and a new program number is commanded and stored in the means 4. Then the programs of all stored numbers are transferred and therefore the programs needed for execution are all stored in an external memory medium.

Filed: 1996-07-01
Abstract: PROBLEM TO BE SOLVED: To allow one multiplex broadcast receiver to keep the newest data at all times as position-correction data and traffic information data by extracting newest data of the traffic information system and correction data. SOLUTION: A RAM 33 stores data, denoting a frequency at which DGPS correction data are broadcast and data denoting a frequency at which VICS data are broadcast. Data of frequencies of broadcast stations broadcasting DGPS correction data are read from the RAM 33, and the frequency data are fed to a reception circuit 22 through a port 34 to select broadcast stations broadcasting the DGPS correction data. Similarly the frequency data of the broadcast stations, broadcasting VICS data, are read from the RAM 33 and the broadcast stations are selected. Thus, even when the DGPS correction data and the VICS data are broadcast from different broadcast stations, both the data are received by one receiver 20.

Title: Thin film type optical element and its manufacture
Inventor: MIYAWAKI MAMORU
IPC: G02B6/12
Filed: 1985-08-29
Abstract: PURPOSE:To increase the threshold value of an optical damage and to improve the coupling efficiency in the input and output stage of guided light by providing an optical waveguide formed by implanting or thermally diffusion ions to a substrate surface and a region where the ions are neither implanted nor thermally diffused. CONSTITUTION:Parallel light 8 from a laser are condensed by a cylindrical lens 5 onto the end face 3 of the optical waveguide in the thickness direction of the optical waveguide 2. The condensed light is coupled into the waveguide 2. The guided light 9 coupled therein is diffracted by a surface acoustic wave 10 generated in a comb- shaped electrode 7. The diffracted light is emitted as parallel light from the end face 4 of the optical waveguide. The width of the condensed luminous flux at the end face 2 is approximately the same as the width of the light 9; therefore, the high coupling efficiency is obtd. The depth of the implanted protons is smaller and the proton density is higher nearer an optical function part 41 of the waveguide 2. The light 9 is, therefore, confined near the surface of the substrate 1 in the function part 41 and the high diffraction efficiency is obtd. Since the electrodes 7 and 20 are formed on diffused titanium layers 21, 22 in the regions where the protons are not implanted, the decrease in the piezo-electric characteristic by the proton implantation is obviated.

IPC: A47L15/42
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To cool a high-temperature liquid stored in equipment, while draining it. SOLUTION: When high-temperature washing water 118 (rinsing water) stored in the water reservoir 113 of a dishwasher 101 is drained through a discharge pipe 133, a water flow sensor 211 detects the water drained and outputs a drain detection signal to a cold water mixing control part 213. The cold water mixing control part 213 opens a first opening/closing valve 209 in response to this output. As a result, cooling water 205 stored in a tank 203 passes through a cooling water pipe 207, and since the cooling water 205 mixed at a mixing part 215 with the washing water 118 flowing through the discharge pipe 133 is lower in temperature than the washing water 118, the mixed water 219 cooled to low temperature flows thorough the discharge pipe 217.

Abstract: PURPOSE: To cope with a vicious deed of modifying a content by a breakage of a container by superposing two films molded in a sawtooth state so that an incident light ray is totally reflected on one side surface of a transparent thermoplastic film. CONSTITUTION: One side surface 2 of a colorless or colored transparent thermoplastic polymer 1 is molded in a sawtooth state crossing at an arbitrary angle in a single or a plurality of directions or similar protrusion and recess shape to totally reflect an incident light ray 3 from a flat surface of its opposite side. A composite film obtained by superposing the two films 5, 6 so that directions of grooves of the protrusion and recess shape form a certain angle therebetween is used as the packaging container material. When a liquid is filled in the packaging container and a pore is externally opened by a syringe needle, the liquid in the container is immersed into gap at the superposed part of the wall face of the container to vanish a total reflection of the container to vanish a gloss and to increase a transparency.  This vicious and dangerous deed can be immediately clearly sensed.

Title: Lead-out system for digital message
Inventor: OGAWA YASUNORI
IPC: H04M3/50
Filed: 1984-09-12
Abstract: PURPOSE:To discriminate the start time point for transmission of a voice message by defining a digital code which is not used to the voice message as a lead-out code and adding this lead-out code to the head of the message for transmission of the message through the same message channel. CONSTITUTION:When a subscriber 6 gives a call to a talking trunk 21 to listen to a voice message, the ringing tones are sent back to the subscriber 6 from a ringing tone generating circuit 214. While a serial/parallel conversion circuit 215 converts a lead-out code H and a digital message code train M sent from a message output device 100 into parallel codes. While a lead-out data generating circuit 216 produces the code H and transmits it to a comparator 217. The comparator 217 compares a digital code with the code H and supplies the logic '1' to an FF21 when the coincidence is obtained between both codes. As a result, '1' is delivered through a gate 212 and a selector 213 connects a message line 4 to a channel 12. Then the code train M is sent back to the subscriber 6 from the device 100 via the selector 213, the channel 12 and a switchboard 3.
