Title: Intake device of internal-combustion engine
Inventor: MATSUNAGA MASANOBU
IPC: F02M35/12
Filed: 1983-10-27
Abstract: PURPOSE:To previously avoid generation of noise due to a back flow of pressurized air at the time a throttle valve is completely closed during supercharging operation by arranging a muffler in an intake path on upper stream side from an impeller. CONSTITUTION:At the time of supercharging operation of an engine 1, the impeller 14 of a turbo charger 4 rotates with high speed (for example, 100,000rpm), compresses intake air, and supercharges it to a cylinder 12. And when a throttle valve 13 is rapidly closed, air of high pressure in an intake path 11 which is on the upper stream from the throttle valve 13 and on the lower stream from the impeller 14 flows backward as it expands to the inside of the intake path 11 which is on the upper stream side from the impeller 14 of low pressure (approximately the atmospheric pressure), and it generates noise of 200Hz-2kHz. This noise can be silenced by a muffler 20 which is arranged in the intake part 11.

Abstract: PURPOSE:To simplify construction and contrive to reduce cost, by arranging a printing head and a correcting head side by side along a platen, and causing one of that two heads to function a guide member for bringing an ink ribbon into contact with a paper when the other head is used. CONSTITUTION:At the time of normal printing, an ink ribbon 10 is pressed against a paper 3 by a printing thermal head 32, and the head is supplied with printing energy while a carriage 8 is moved along a platen.

Title: Magnetic recording and reproducing device
Inventor: MORITA NOBORU
IPC: G11B5/02
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To recover read errors by eliminating Barkhausen noise and baseline shift that generate at the time of signal reproduction in a magnetic recording and reproducing device using an MR head. SOLUTION: The magnetic recording and reproducing device uses an induction type magnetic head at the time of recording information and a magnetoresistance effect type head (MR head) at the time of reproducing the data. In this case, if lead errors take place due to the MR head at the time of the reproduction of the data, an alternate attenuation current is energized to the magnetoresistance effect film of this head. As a result, the magnetic domain inside the MR film becomes a single domain structure to eliminate Barkhausen noise and baseline shift, so that read errors can be recovered.

Abstract: PURPOSE:To stably obtain a grown structure of multiple layers, by providing shallow melt chambers which are respectively communicated with a plurality of melt resevoirs placed in a row, and a slide plate provided in the bottom surface thereof with a recess capable of housing a semiconductor substrate, and controlling the slide plate and a partition plate. CONSTITUTION:A melt 12 of a predetermined impurity concentration is placed in a melt reservoir 2, while a semiconductor substrate 19 is attached to a recess 9. This is heated in a furnace to a predetermined temperature and is then left as it is for a while. In this case, a control bore 7 is not coincident with any communicating bore 4, and the recess 9 is located directly above a melt chamber 3. Then, a partition plate 6 is slid such as to allow the control bore 7 and the communicating bore 4 in the melt chamber 3 to coincide with each other. Thereupon, the melt 12 flows into the melt chamber 3 to contact the surface of the substrate 19. After the partition plate 6 is slid again, the temperature is lowered at a predetermined rate to effect epitaxial growth. After the growth has been completed, a slid plate 8 is slid such that the recess 9 is located directly above another melt chamber 3. Thus, epitaxial growth is repeated the number of times equal to that of the melt chambers 3.

Abstract: PURPOSE:To facilitate easy control with no bend of an optical axis and at the same time to attain the application of LDs the same in oscillating wave length, by providing an optical multiplexing means and a means which polarizes the transmitted light in an optical path of one side of the radiated light by a micro angle, and detecting the light of one side of each light emitting means from the light given from a recording medium. CONSTITUTION:Two parallel beams are multiplexed by an interference filter 14 to make perfect coincidence between the polarizing directions and optical axes of two beams. Under such conditions, two LD beams are focused at the same point. Here a prism 24 is put into the optical path of a recording LD10a, and therefore the transmitted light of the prism 24 is polarized. Thus two spots which are separated from each other in terms of space are formed at the focused point. The reflected beams of the two separate spots are extracted by a polarized beam splitter 21. An interference filter 25 detects only the light of a regenerating LD10b and leads it to a detecting system 26 to perform record and reproduction. In this case, the operation is stable since the record and reproduction spots are separated from each other. In addition, the optical system is also controlled simply just by inserting the prism 24 after obtaining once coincidence between two optical axes.

Abstract: PURPOSE:To circulate refrigerant with a small-sized liquid pump by providing a liquid receiving a liquid receiving tank, a vaporizer, and a condenser, and installing a first pipeline, a second pipeline, a return pipeline, and a loop pipeline and a liquid condenser above the liquid receiving tank. CONSTITUTION:The refrigerant in a liquid receiving tank 31 is adapted to pass through a first pipeline 39 and flows into a vaporizer 32 by means of a liquid pump 41 where it is vaporized. Then, it flows into a condenser, passing through a second pipeline 42 where it is condensed, thereby heating the indoor air. Then, the refrigerant circulates into the liquid receiving tank 31, passing through a return pipeline 45. A loop pipeline 71 is installed to a gas section 69 in the upper part of the tank 31 where a liquid condenser 59 is installed above the tank 31. Due to this construction, the refrigerant gas portion which flows into the gas section 69 in the tank 31 from the return pipeline 45, is arranged to flow into the liquid condenser 59, passing through the loop pipeline 71 where it is recondensed and drops into the tank 31 by gravity where it is decompressed and sucked up into the tank 31. It is therefore, possible to reduce the size of the liquid pump 41.
