Title: Exhaust heat recovery piston engine
Inventor: NISHIWAKI JINICHI
IPC: F02M31/08
Filed: 1990-06-29
Abstract: PURPOSE:To enhance thermal efficiency of an engine by injecting or igniting fuel after compressed air or mixture is heated through a heat exchanger by exhaust heat and supplied to a combustion chamber. CONSTITUTION:An intake valve 3, exhaust valve 4, outflow valve 5 and an inflow valve 6 are provided in an upper part of a cylinder 2 to connect the intake valve 3 to the atmosphere, exhaust valve 4 to outside the cylinder via a primary flow path 7a of a heat exchanger 7 and the outflow valve 5 to the inflow valve 6 through a secondary flow path 7b of the heat exchanger. The atmospheric air is sucked into the cylinder 2 in a stroke of lowering a piston l to the bottom dead center by opening the intake valve 3, and next the air is compressed to increase its temperature in a stroke of lifting the piston toward the top dead center by closing the intake valve 3. Successively, when the piston l comes to the top dead center, the compressed air is allowed to flow in the secondary flow path 7b of the heat exchanger by opening the outflow valve 5, and the air is heated by utilizing exhaust heat, discharged from the cylinder 2, to flow into the cylinder 2 from the inflow valve 6. And then combustion is performed by injecting fuel from a nozzle 8.

Title: Sewing machine driving device
Inventor: YASUNOBU ISAMU
IPC: D05B69/18
Filed: 1982-09-28
Abstract: PURPOSE:To set plural speeds without requiring a switch with >=2 electrodes by detecting the impedance of a resistance connected to an input terminal, and driving and stopping a sewing machine and controlling its rotating speed during the driving on the basis of the impedance. CONSTITUTION:When switches 52 and 54 are both off, the impedance between terminals (e) and (d) is infinite, so the output of a converting means 41 drops below a reference voltage vs and the sewing machine is still off. When one switch 52 is turned on, a variable resistor 51 is connected, so setting the impedance to r1 allows the converting means 41 to output a voltage v3 and the sewing machine rotates at the rotating speed corresponding to the voltage. When the switch 54 is turned on, a variable resistor 53 is connected, so setting the impedance to r2 allows the converting means 41 to output a voltage v4 and the sewing machine rotates corresponding to the voltage.

Title: Manufacture of float
Inventor: SASAKI TAKAO
IPC: B29D22/00
Filed: 1983-09-14
Abstract: PURPOSE:To manufacture a float being highly resistive to the breaking due to water pressure by a method wherein compressed air is injected into a float through a plug hole made in the main body of the float, and simultaneously a taper plug, rotating at high speed, is pressed into said hole and welded thereto. CONSTITUTION:The main body 3a of a float provided with a rope-engaging member 3b and a plug hole 3c is formed by blow molding by using polyethylene or ABS resin, and compressed air of 1-3kg/cm<2> is injected into the main body through the plug hole 3c. Immediately after the injection, a taper plug 5 made of the same material as the float is pressed into the hole by a rotary power of 10,000rev/sec or above, and simultaneously the taper plug 5 is welded integrally to the plug hole 3c by a frictional heat caused by the rotation. The float thus prepared is best suited for retaining a rope for seaweed-culture etc. The float does not explode even when it sinks under water due to the weight of the rope, since compressed air is pressed therein. The plug is sealed up excellently.

Title: Clipping method
Inventor: NOMA MUTSUAKI
IPC: G06T11/00
Filed: 1988-07-07
Abstract: PURPOSE:To avoid the excess consumption of planes and to attain the easy clipping of a high speed by comparing the same coordinates of the two planes and generating a clipping graphic only with setting a compared result to the same coordinate of the display plane. CONSTITUTION:A plane 1 is set to be used for the clipping out of plural memory planes. Then, a pixel corresponding to the internal part of a clipping area 5 is turned on and a pixel out of the area is turned off. After that, for the graphic to be prepared, a pixel to be displayed in another plane 2 is formed to be turned on and the other pixel is formed to be turned off. The plane for clipping and the pixel in the same coordinates of the plane in the prepared graphic are compared and decided, and only the pixel to be turned on and to be in the same coordinates of a plane 4 for display is turned on. Then clipping graphic is generated and displayed. Thus, without holding the information of the clipping area in a memory table, etc., and providing a means to execute the decision for the inside and outside of the clipping area and computation at all, the arbitrary graphic can be easily generated in the arbitrary clipping area at the high speed.

Title: Contrast composition for mri diagnosis
Inventor: HASEGAWA HIDEO
IPC: A61K49/00
Filed: 1993-07-09
Abstract: PURPOSE:To provide a contract composition capable of being applied to the lower part tissues of a living body and used for MRI (nuclear magnetic resonance image) diagnose. CONSTITUTION:A contrast composition is characterized by containing free divalent magnesium cations large in an effect for shortening a spin-lattice relaxation time T1 as a paramagnetic substance for imaging with MRI as the main ingredient of the contrast composition. The concentration of the magnesium cations is optimized within a range of 5-50mum/nl so that the contrast agent is brightly expressed in a T1-emphasized image and that the contrast agent is darkly expressed in a T2-emphasized image (T2 is a spin-spin relaxation time). A MRI diagnose highly safe for living bodies can be performed in a fine dose of the manganese ions by directly administering the contrast composition into a living body lower part tissue such as a large intestine, a bladder or an uterus. Since the original brightness of the T2-emphasized image is not interfered within the concentration range, the diagnose of a tumor lesion is not inhibited.

Title: Frequency synthesizing device

IPC: H04B1/7143
Filed: 1988-07-12
Abstract: PURPOSE:To reduce an unstable section in the switching of a frequency and to improve transmission efficiency by providing two tuning type band-pass filters at an output stage, and switching and using them selectively by a switching control signal. CONSTITUTION:A frequency synthesizer 1 outputs a hopping signal whose frequency channel changes in prescribed sequence by a frequency control signal. It is assumed that the output signal performs frequency hopping in sequence of the frequency channels F1, F2,... as shown in figure (a). Switches 2 select the tuning type band-pass filters 3a and 3b alternately with a switching control signal with a timing (the timing synchronized with the frequency control signal) shown in Fig. (a), and the output signal is filtered and outputted from the frequency synthesizer 1. In such a way, it is possible to reduce a period where data becomes unstable at the time of switching the frequency, and to improve the transmission efficiency.
