Title: Image recording
Inventor: KOSHIZUKA KUNIHIRO
IPC: B41N1/08
Filed: 1989-03-09
Abstract: PURPOSE:To form a high-resolution, sharp image easily by forming an original image of hydrophobic material on the surface of a support with a hydrophilic surface, then allowing water ink or alcoholic ink to be adsorbed in a hydrophilic area and transferring the image to a medium-for recording. CONSTITUTION:When an original image is formed by a thermally sensitive, transferable recording medium 6, this medium 6 is composed of an ink layer 5 containing a thermally fusable material or a softening resin and coloring material such as dye or pigment formed on a support 4. A thermal head heats the ink layer 5 so that it is transferred to the hydrophilic surface of the support 2, and a hydrophobic area 3 is formed on the surface of the support 2 to obtain an original plate 1. Next the original plate 1 is wound around a winding roll 11 in such a manner that the surface where the original image is formed is turned outward. After this, the lower peripheral surface is soaked in the water ink or alcoholic ink and at the same time, the roll is rotated so that the ink is supplied to it. Then the extra ink is removed and the hydrophilic area is caused to adsorb the ink, and the medium for recording is moved close to the upper periphery surface of the winding roll to allow the medium. Consequently, it is possible to form a high-resolution, sharp image easily.

Title: Diesel engine
Inventor: URAKI YOICHI
IPC: F02D41/40
Filed: 1995-03-16
Abstract: PURPOSE: To improve smoke performance and to reduce NOx by reducing engine noise in a middle load domain using an injection nozzle having a low initial injection rate, and carrying out a high rate EGR to delay a fuel injection term, and shortening a fuel injection term in a low load domain. CONSTITUTION: A control unit 13 controls a EGR valve 7 through actuator 8 on signals sent from the rotation sensor 9 of an engine body 1, an accelerator opening sensor 10, a water temperature sensor 11 and a fuel temperature sensor 12. A high rate EGR is carried out in the low load domain of an engine body 1 to delay the fuel injection time of an injection nozzle 5 for lengthening an ignition lag term, and fuel injection pressure from the injection nozzle 5 is relatively heightened by the injection pressure varying means of a fuel injection pump 4. The injection term in the low load domain is thereby shortened. Thus the injection nozzle 5 opened in two stages restrains the abrupt rising of combustion pressure which causes engine noise in a middle load domain, and on the other hand produces premix combustion in the low load domain to restrain the generation of smoke.

Abstract: PURPOSE:To obtain a highly sensitive sensor for measuring a mixing rate or the like for an alcohol/gasoline mixed fuel with an easier maintenance in a small size by forming a folded part of a glass optical fiber with a large caliber from a core alone. CONSTITUTION:A linear optical fiber 2' comprising a core alone is placed on a non-heat conductive die 3 to soften the fiber 2' by locally heating a corner part 14 with a small burner 15 or the like, so that the tip 16 of the fiber 2' bends by a dead load thereof. Then, an excess part of the fiber 2' is cut off to form a folded part 2c, which is fused by heat to fibers 2a and 2b comprising a core and a clad. Then, a light emitting element 3 and a photo detector 4 are inserted securely into a body 5 to form a sensor. When the folded part 2c of a sensor thus obtained is exposed into a liquid to be measured, a transmission loss increases according to a refractive index of the liquid. Thus, a mixing ratio of the liquid can be measured with a high sensitivity thereby enabling the obtaining of a small and easy to maintain sensor.

Title: Electroacoustic transducer
Inventor: YONEYAMA MASAHIDE
IPC: H04R1/28
Filed: 1984-03-26
Abstract: PURPOSE:To cut harmful high-power ultrasonic waves for human bodies and to obtain an electroacoustic transducer with a little of a loss of secondary waves by providing an acoustic filter for interrupting a primary ultrasonic wave in a prescribed position away from a front of a piezoelectric vibrator. CONSTITUTION:A speaker employs a parametric function. The limited amplitude ultrasonic wave whose amplitude is modulated by an audible sound is radiated from a piezoelectric vibrator array 5, and propagates in air. During the propagation in air, self-demodulation of the wave is performed by influence of a non-linear characteristic of air, and accordingly a virtual sound source of a secondary wave (modulated audible sound) is formed in beams of the primary wave, whereby a secondary sound field of a sharp directivity is formed. Here, sound pressure of the primary wave is substantially large, and harmful for bodies. Consequently, an acoustic filter 6 is provided L (L=R0/2alpha; R0 is rayleigh length; alpha is attenuation coefficient of ultrasonic wave in air) away from the piezoelectric vibrator array 5, and the harmful primary wave is eliminated.

Abstract: PURPOSE:To extend the life of a light source by reducing the consumption of a battery and to alleviate the pain of an examinee by stopping light emitting operation for a predetermined time when it is detected that the saturation degree of oxygen in arterial blood is unstable timewise. CONSTITUTION:When a light emitting part 2 starts light emission at predetermined frequency by the light emitting order of an operation part 7, the saturation degree of oxygen in arterial blood and a pulse rate are calculated from the signal outputted from a signal processing part 6 on the basis of the operation of a light detecting part 3 and that of a photoelectric conversion part 4 and the stabilities thereof are investigated. Next, it is judged whether the calculated saturation degree of oxygen in arterial blood and pulse rate are within set ranges and, when the measured values are within an alarm range, measurement is continued. When the measured values are judged to be stable and also judged to be not within the alarm range, an operation part 7 issues a light putting-out order to a light emission control part 5 to stop the light emission of the light emitting part 2. After a predetermined time is elapsed, the light emission of the light emitting part 2 is reopened and the same operation is repeated in the same way.

Title: Intake port structure of engine
Inventor: KOMADA HIDEKI
IPC: F02F1/42
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To strengthen a swirl and prevent the occurrence of scattering in performance in manufacturing steps by improving on a shape of an intake port of an automobile engine. SOLUTION: An intake port 5 is divided into a perpendicular passage part 5a which opens to a combustion chamber 2 and an inclined passage part 5b which communicates with the perpendicular passage part 5a. A flat part 5d extending with respect to the inclined passage part 5b at an angle of α is formed at a lower part of a boundary part 5c at which the perpendicular passage part 5a and the inclined passage part 5b are connected. The flat part 5d and the perpendicular passage part 5b constitute an edge 9. Due to a peeling phenomenon of the edge 9, a swirl of an air fuel mixture flowing along a wall surface becomes strong. Because of forming the flat part 5d, a predetermined edge form can be maintained even if a mismatch of the intake port 5 accurs in the time of manufacturing. Accordingly, scattering can be prevented from occurring from the viewpoint of its performance.
