Title: Duplicator
Inventor: YAMAMOTO TATSUO
IPC: G11B20/10
Filed: 1979-02-13
Abstract: PURPOSE:To obtain a slave tape from a digital disc to prevent damage of a master tape, by subjecting analogue signals, which are recorded on the master tape, to digital conversion and time base conversion and recording them onto the digital disc. CONSTITUTION:Signals recorded on master tape 2 are applied to analogue-digital conversion circuit 9 and are written into time base change memory 11a. When contents of the memory are read out through contact 12a, the time base is compressed, and the read output is recorded on magnetic disc 13. When this magnetic disc is mounted on plural magnetic disc reproducing devices 15a, 15b and 15c and they are operated in parallel, signals are read out through digital-analogue conversion circuits 19a, 19b and 19c and are compressed to a speed as 32 times as high as the normal speed and are recorded onto slave sound recording device 21a. Consequently, a slave tape can be obtaned in the 1/32 time of the normal tape speed without high-speed rotation of the tape, and wear of the master tape can be prevented.

Title: Antilock brake device
Inventor: KATO JUNICHI
IPC: B60T8/58
Filed: 1993-02-02
Abstract: PURPOSE:To improve the operation of an antilock brake by providing a means by which the lock condition of a center differential gear can be released by the signal for indicating the operation of the antilock brake. CONSTITUTION:In the lock condition of a front axle and a rear axle, either one of crown gears 1 is moved, and the couple of the crown gears 1 is in a fitted condition. In this condition, if an antilock brake device is operated, an antilock-brake control signal is output from a program control device 11 to a relay circuit 12. By this output, the coil 12a of the relay circuit 12 is excited, and a contact 12b is opened to cut off the supply of current to a solenoid valve 14, so that the pipeline from a pressure source 13 to a hydraulic pressure cylinder is close. Thereby, the pressing force of the crown gears 1 is stopped, and a slipping-out force is caused to the couple of the crown gears 1 due to the difference in the driving torque between the front axle and the rear axle, so that the fitting of the crown gears 1 is disconnected. Thus, the operation of the antilock brake device is effectively carried out.

Title: Wire rod winding method
Inventor: KEMI JOICHI
IPC: B65H54/38
Filed: 1988-01-26
Abstract: PURPOSE:To prevent a wire rod from being wound on the same locus and to flatten a winding outer surface, by a method wherein the moving speed of a guide roller is varied each time it is reciprocated the proper number of times so that wire rod reversing positions at both ends of a bobbin are changed. CONSTITUTION:A moving speed V of a guide roller 4 is varied at intervals of the number of times, form example, one full reciprocation. The moving speed V is controlled by a CPU so that a relation W/P between a width W of a bobbin and a winding pitch P of a wire rod 5 is at random. Thus, the reversing position of the wire rod 5 is slightly varied at random, and the wire rod 5 is prevented from being wound on the same locus. This method causes flattening of a winding outer surface and improves delivery of the wire rod 5.

Title: Ink jet recording liquid
Inventor: ISHII FUMIO
IPC: C09D11/328
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To obtain an ink jet recording liquid which gives images excellent in light resistance and chroma by incorporating a specific arom. carbocyclic or hetrocyclic compd. into the same. SOLUTION: At least one compd. of the formula: A-J-B is incorporated. In the formula, A and B are each independently an arom. carbocycle or heterocycle; and J is a tetravalent arom. linking group bonded to A and B, individually via a divalent linkage. An example of the compd. of the formula is a compd. of formula I. The reason why the compd. of the formula improves the light resistance of a colorant for ink jet is supposed to be that the compd. acts as a donor for the colorant as an acceptor and thus encloses the colorant. Pref., an azomethine colorant (e.g. a compd. of formula IV) derived from a pyrazoloazole of formula II or I (wherein R1 and R2 are each II or a substituent) is incorporated as a Magenta colorant into the recoding liquid. Pref., 0.1-25 wt.% colorant and 0.1-25 wt.% compd. of the formula are used based on the amt. of the recording liquid.

Title: Method and device for discriminating character graphic from background area and recording medium recording its method
Inventor: KOBAYASHI KIMITOMO
IPC: H04N1/407
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To discriminate a frameless character, an inverted character graphic, etc., without converting the RGB values of a color image into information such as a hue, brightness and saturation and to quickly discriminate an edge-emphasized character graphic or the like without requiring specific processing. SOLUTION: A color area detection part 2 detects similar color areas by directly comparing RGB values in a color image, and when each of the color areas has regulated size and shape, a pixel sorting part 4 sorts the pixels of the color area by using the differences of RGB values and counts up the number of sorted pixels. When the 2nd higher number of pixles out of sorted pixels is included within a regulated range, a character extraction part 5 discriminates an area of the highest number of pixels as a background area, discriminates an area of the 2nd higher number of pixels as a character graphic so as to discriminate a frameless character graphic, an inverted character graphic, or the like and binarizes a character in a color area.  The RGB values of the area of the highest number of pixels are compared with that of the area of the 2nd higher number of pixels, the area having higher brightness is extracted as a reference and a character in the color area is binarized to remove the influence of an edge-emphasized character or the like.

IPC: H01L23/473
Filed: 1989-01-26
Abstract: PURPOSE:To eliminate the need to vary the flow velocity of a coolant by another unit and to make it possible to exhaust efficiently heat outside of an apparatus by a method wherein nozzles directed straightly toward holes provided in a cold plate is tapered off to increase the flow velocity of the coolant so that the coolant is spouted against the bottom of the holes. CONSTITUTION:When a coolant 7 flowing into a cooling container 11 through an intake 8 fills a suction chamber 15 sectioned by a partition 10, the coolant passes through a pipe 12 and spouts the coolant collides against the bottom of a hole 5 in a cold plate 6. As the point of a nozzle of the pipe 12 is narrowed finely, the flow velocity of the coolant 7 is increased and the coolant and spouts strongly. Moreover, the coolant passes through a nozzle 13b and a pipe 13 and is sent to the adjacent hole 5 through a nozzle 13a. In such a way, the coolant 7 is sent in order to holes 5 and lastly, is collected in an exhaust chamber 16 and is exhausted outside through a discharge port 9. Thereby, heat can efficiently be exhausted to outside of the apparatus without making the flow velocity of the coolant vary by another unit.

IPC: G11B5/127
Filed: 1981-02-08
Abstract: PURPOSE:To obtain a recording/reproducing head having high efficiency and good wear  properties, by setting the magnetic medium flow-in side unparallel to the flow-out side  of a main magnetic pole in a length of several-fold as much as the mean wavelength  and at the same time increasing the thickness of the magnetic medium. CONSTITUTION:A main magnetic pole 21 of high saturation magnetization such as  sendust or an amorphous ferromagnetic matter is set at the tape flow-out side; while a  reinforced core 8 of ferrite, etc. is set at the tape flow-in side, respectively. A residual  magnetizing pattern of a high-coercive medium 5 is decided only on the surface of the  flow-out side of the pole 21 of high saturation magnetization. The other surface of the  pole 21 plus both surfaces of the core 8 are set unparallel to the flow-out side surface  of the pole 21. Thus the reproduced voltage is decided by only the flow-out side surface of the pole 21. As a result, a recording/reproducing head can be brought into contact with the tape with the pole 21 and the tip surface of the core 8 set at the same  level. Accordingly the change of the recording characteristics due to the wear can be  avoided, and at the same time the transmission factor of magnetic flux is extremely  increased between the tip of the pole 21 and the coil part to obtain high efficiency and  high sensitivity.
