Title: Magneto-optical recording and reproducing device
Inventor: OTOGAWA MITSUHIRO
IPC: G11B5/02
Filed: 1989-03-09
Abstract: PURPOSE:To remove a bit shifting variable by momentarily changing the shifting variable of a magnetic field modulating pulse at the time of recording in accordance with the linear speed of a recording medium detected by a parameter. CONSTITUTION:Data 12 recorded on an objective track are inputted to a magnetic field modulating pulse generating circuit 9 and the circuit 9 outputs a magnetic field modulating signal to a coil driver 4 together with a certain shifting variable. The shifting variable is found out by calculating the linear speed of a disk obtained by using the radius distance of the objective track as a parameter based upon a signal outputted from a motor control circuit 13 and calculating the shift value by the circuit 9 in accordance with the linear speed. Then, a magnetic field generating pulse delayed by the shift value of the objective track is formed. Consequently, the bit shift of a reproduced signal can be removed independently of the change of the linear speed and the generation of a bit error can be prevented.

Title: Film or sheet for clean room partition
Inventor: KATO TOSHIYUKI
IPC: E04H5/02
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To enhance the antistatic properties, flameproofness, transparency and pliability by laminating a fluororesin film on both faces of an antistatic transparent soft film or sheet of a vinyl chloride resin, in the film or sheet to be used for partitioning in a clean room where semiconductors or the like are manufactured. SOLUTION: A fluororesin film 11 is laminated on both faces of an antistatic transparent soft sheet 10 of a vinyl chloride resin through a vinyl chloride adhesive 12. Thus a sheet 1 for partitioning in a clean room is obtained that is free from the generation of an outgas and is well acceptable in terms of light resistance, antistatic properties, flameproofness (flame retardance), transparency and pliability. The fluororesin film 11 to be used is acceptably a film consisting of a fluororesin layer made of a fluororesin, an acrylic resin layer and/or a vinyl chloride resin layer as laminar elements. In addition, a flame retardant, a pigment, an antioxidant, an ultraviolet absorbent and the like may be properly added to the vinyl chloride resin according to necessity.

Title: Fuel jet pump for diesel engine
Inventor: KANOU KATSUNOBU
IPC: F02M59/24
Filed: 1979-05-07
Abstract: PURPOSE: To eliminate the butt-surfaces of a plunger valve and a delivery valve tube for avoiding such worst operational condition that fuel jetting is stopped due to the fall of fuel pressure, even if a packing has loosened, by constructing the plunger valve and delivery valve tube monolithically.  
     CONSTITUTION: A stepped sleeve 9 monolithically having a plunger barrel 2 and a delivery valve tube 4 is provided, and a plunger 1 and a delivery valve 3 are inserted therein. This fuel jet pump is fitted, with a packing 5 pressed by an end of a delivery valve holder screwed in a pump assembly body and a shoulder portion of a plunger barrel 2 engaged with that of the body. The plunger barrel 2 and delivery valve tube 4 are monolithic and differ from the conventional ones of the kinds in that there is not butt-surface therebetween. Even if a packing 5 has loosened in operation, therefore, the leakage of fuel from a pump chamber 7 can be prevented.

Title: Refrigerator
Inventor: NANRI SATOSHI
IPC: F25D21/04
Filed: 1993-03-16
Abstract: PURPOSE:To provide a refrigerator which is free of generating freezing at a flow outlet in a refrigerator. CONSTITUTION:A cooled air supplied into a refrigerator from a refrigerator supply passage 33 is adapted to flow out into a vegetable chamber supply passage 33 from a flow outlet 42 and introduced into a vegetable chamber from the vegetable chamber supply passage 33. At that time, a part of cooled air is supplied to a combined chamber 41 of the vegetable chamber supply passage 33 to which the flow outlet 42 is opened by way of a combining flow passage 43. A cut-off wall 44 is installed protrusively and integrally to an insulation material-made lower duct 37 which forms the combining flow passage 43. This cut-off wall prevents the cooled air from flowing out into the flow outlet 42 from the combining flow passage. This construction makes it possible to protect the flow outlet 43 from being cooled with the cooled air and eliminate the potentiality of freezing in the area around flow outlet 42. Since the cut-off wall 44 is made of an insulation material, no dew condensation is produced on the cut-off wall 44 even if the cooled air from the refrigerator comes into contact with the cut-off wall 44. More specifically, there is no danger that the water drops will be frozen even if dew condensation is produced.

Abstract: PURPOSE:To generate a mist with a low salt concn. and to inexpensively perform desalting and preparation of water by emitting an ultrasonic wave from a point below the liq. surface toward the gas phase at ordinary temp. and under ordinary pressure. CONSTITUTION:A plurality of desalting apparatus adjoiningly provided with a water manufacturing apparatus are arranged so as to connecting them in series and sea water is introduced through a path 2 into small rooms divided into a plurality of rooms in a main body container 1 and overflowing water is discharged from a path 3. A plurality of ultrasonic oscillators 7 wherein the output is controlled by means of a pulse adjusting device 8 are provided in each small room and mist generated by means of ultrasonic emitting is transferred into the second small room from a path 6 by means of air introduced through a path 5. Then, successively, by passing it through each soil room, the salt concn. is gradually decreased and the mist generated from the last small room is passed through a path 4 and is sent into a tank, wherein it is stored. In this instance, water is returned by a slower speed than that of the preceeding mist generating speed and the concn. of the salt content is decreased thereby.

Abstract: PURPOSE: To localize an area to detect a signal by applying an excitation pulse of<1> H as a slice selection pulse under slice gradient magnetic field and applying a gradient magnetic field for re-focusing in the slice gradient magnetic field when one quantum coherence of<1> H after multiple quantum coherence is generated. CONSTITUTION: In this pulse sequence, a cylindrical area is excited selectively by applying slice selection excitation for a direction of X-axis and that of Y-axis, respectively. Moreover, as for a remaining direction of Z-axis, a C-H correlation two-dimensional spectrum for a local area is acquired by applying encoding. In this sequence, frequency adjustment on a 90 deg. pulse of<1> H which excites only<1> H selectively is performed so as to excite a specific slice area selectively, and it is set as a slice selection excitation pulse for X-axis, and applied under the slice gradient magnetic field(Gx). Therefore, localization is attained for a first axis(X-axis) and two quantum coherence and selection can be attained.
