Abstract: PROBLEM TO BE SOLVED: To provide a silver halide color photographic sensitive material of high sensitivity having smooth appearance of skin color and showing both of the reproducibility and stability. SOLUTION: Each of this photosensitive material consists of at least one layer of blue-sensitive silver halide emulsion layer containing a coupler, which develops a yellow color, a green-sensitive silver halide emulsion layer containing a coupler, which develops a magenta color, and a red-sensitive silver halide emulsion layer containing a color coupler, which develops a cyan color on a supporting body. This silver halide color photographic sensitive material has such properties that when it is exposed to light corresponding to (min. red absorption density + 0.3) in the masking characteristics of green density obtd. by exposure with separated red color, it gives >=0.04 overmask and >=320 specific photographic sensitivity.  Moreover, the RMS graininess after development of the photosensitive material is <=13 for green light, and the ratio of the RMS graininess R of the red-sensitive layer to the RMS graininess G of the green-sensitive layer (R/G) is <=1.0.

Title: Ink jet printing head
Inventor: SHIODA TOYOJI
IPC: B41J2/175
Filed: 1985-12-09
Abstract: PURPOSE:To prevent the pressure of an ink in an ink chamber from being fluctuated and obtain an ink jet printing head capable of printing with favorable quality and being highly reliable, by providing a horn form ink-supplying passage between a pressure chamber and the ink chamber, the passage being enlarged toward the ink chamber. CONSTITUTION:When printing by jetting ink droplets, an ink pressure wave generated in a pressure chamber 22 for jetting the ink droplet is propagated simultaneously to a nozzle 21 and an ink-supplying passage 23. The ink-supplying passage 34 is formed in the shape of an exponential horn. The sound wave passing through the horn can not be transmitted in a frequency range below a cutoff frequency fc. Therefore, when dimensions are so set that the cutoff frequency fc is higher than the frequency fe of residual vibration of the pressure wave generated in the pressure chamber 22, the sound wave propagated into the ink-supplying passage 34 is not propagated into an ink chamber 24, due to the change in cross-sectional area of the horn shape of the passage 34. Accordingly, the pressure of the ink in the ink chamber 24 can be prevented from being fluctuated.

Title: Locating apparatus of faulty section of aerial transmission line
Inventor: KANO HITOSHI
IPC: H02H3/30
Filed: 1987-11-04
Abstract: PURPOSE:To enable the execution of location with high reliability, by comparing an overhead ground wire (GW) current before the occurrence of a fault with the GW current after that for location. CONSTITUTION:A fault current measured by a current sensor 4 for each section is multiplexed by a multiplex transmission device 5 and transmitted to a central monitor station 11 through an optical fiber 2 in an optical fiber composite overhead ground wire (OPGW). In the central monitor station 11, GW current waveforms just before the occurrence of a fault and just after that are compared for each section by a relative operation circuit 9. A phase shift and an amplitude difference between the two GW currents are detected in detail by this comparison. A faulty section is located from the result of the comparison and the waveform of the GW current after the occurrence of the fault. Since these phase shift and detailed difference in amplitude are detected by the comparison between the GW currents before and after the occurrence of the fault, a fault point can be located effectively.

CONSTITUTION:Pins 20 for predetermined works are put on a recovery pallet 13b or 13c. After a predetermined number of pins 20 have been supplied on a pin insertion pallet 13a, the vibration and rocking operation by a main body 15 are stopped. At this time, a table returns to the initial horizontal state. Subsequently, the power of electromagnets 10a and 10b is turned on, and by the magnetic lines of force generated between the two, the pins 20 are aligned and vertically stand, and the pins 20 are attracted to the electromagnet 10b side. Then, by rotating a rotary table 11 on which the electromagnets 10a and 10b are mounted, the pins 20 are made to move sliding on the pin insertion pallet 13a in synchronism with the rotational operation of the rotary table 11 while they are held by the magnetic lines of force. Further, by driving a vacuum mechanism 16 to suck the pins 20 into holes 30, only the pins 20 have reached the holes 3 and are correctly orienting with respect to the upward and downward directions are guided and inserted into the holes 30.

Title: Method for feeding paper and recording apparatus
Inventor: YASUE TAKUYA
IPC: B65H3/06
Filed: 1999-09-29
Abstract: PROBLEM TO BE SOLVED: To enhance deskewing accuracy by using a DC motor as a conveying roller driving system, and reducing variations in amount of biting of a conveying roller during deskewing. SOLUTION: When paper fed passes through a paper sensor, an ASF motor which rotates a paper feed roller and a PF motor which rotates a conveying roller are not stopped but kept at constant speeds. When the end of the paper passes through the paper sensor, the ASF motor is driven by n2 steps and the PF motor is driven by m1-a steps to cause a certain length to bite into the conveying roller. A correction (a) is determined for each paper feed speed and the set number of steps is varied according to the selected paper feed speed. Thus, the influences of specification of a speed increase by the PF motor and deceleration curve characteristic are reduced and variations in amount of biting are reduced to enhance deskewing accuracy.

Title: Photosensitive microcapsule and photosensitive material
Inventor: HAYASHI HIROSHI
IPC: G03F7/06
Filed: 1988-11-02
Abstract: PURPOSE:To obtain a picture having a good contrast by forming the shell of a resin formed from a raw material contg. specific isocyanate to the circumference of a core material contg. a silver halide and polymerizable material. CONSTITUTION:The shell consisting of the resin formed from the raw material contg. the isocyanate expressed by the formula I is formed to the circumference of the core material contg. the silver halide and polymerizable material. In the formula, R<1> denotes a hydrogen atom or 1 to 4C alkyl group; R<2> to R<4> respectively independently denote 1 to 3C alkylene group; (n) denotes 0 to 4 integer. The groups may have a substituent. The isocyanate expressed by the formula I has the reactivity equal to or higher than the reactivity of arom. isocyanate. However, the reaction does not progress so much as there is the reaction with the contents in the case of preparing the microcapsules. The prepn. of the resin wall having a high glass transition point is thus possible. Bleeding out of the monomer in the capsules is suppressed in this way even if thermal development is executed at a high temp. The sharp picture is thus obtd. by a short period of a development processing.
