Title: Alternate air pressure imparting method and apparatus for low air loss type patient support device
Inventor: JIYON ETSUCHI BURUZARIKU
IPC: A61G7/057
Filed: 1987-09-09
Abstract: Method and apparatus for preventing bed sores in a bedridden patient (348). A low air loss bed is provided including a frame (12), a first set (321) of substantially rectangular air bags for supporting a patient thereon mounted transversely on the frame (12), and a second set of substantially rectangular air bags for supporting a patient thereon mounted transversely on the frame (12), and all of the air bags are connected to a gas source. The conformation of the air bags is such that, when the first set of air bags is inflated, the patient (348) supported thereon is moved toward the first side of the frame of the low air loss bed and, when the second set of air bags is inflated while the first set of air bags is deflated, the patient is moved toward the second side of the low air loss bed. The conformation of the air bags also retains the patient on the top surface of the air bags when the patient is rolled in one direction or the other. The first and second sets of air bags are mounted on a frame (12) which is itself divided into sets of transversely mounted air bags so that the frame can be contoured to the patient's comfort. Also provided is means for additionally inflating the air bags under those portions of the patient which are heaviest when the frame of the bed is inclined for patient comfort. The method of the present invention comprises inflating a plurality of air bags to a selected pressure for supporting a patient (348) thereon, inflating a first set of air bags to a pressure higher than the selected pressure to cause the patient support thereon to be rolled in a first direction on the air bags, and thereafter deflating the first set of air bags while inflating a second set of air bags to a higher pressure than the selected pressure to cause the patient (348) to be rolled in a second direction on the air bags. A third set of air bags can be provided in which the selected pressure is maintained, thereby substantially immobilizing a portion of the patient's (348) body.

Title: Waveguide type coupler
Inventor: ISODA YOUJI
IPC: H01P5/18
Filed: 1983-11-30
Abstract: PURPOSE:To reduce characteristic deterioration due to the change of frequency and to obtain a large wavelength contraction percentage by using a ridge waveguide having projections of which sectional shape is rectangular as a main waveguide and a sub- waveguide and using a ridge waveguide having projections with a T-shaped sectional shape as branch waveguides. CONSTITUTION:The electric length of the branch waveguides 8 is selected at 90 deg. under f0 frequency and the branch waveguides 8 are arranged in parallel in the longitudinal direction of the main waveguide 6 and the sub-waveguide 7 at the pitch interval of 90 deg. electric length of these waveguides 6, 7. Since the ridge waveguides are used for the main waveguide 6, the sub-waveguide 7 and the branch waveguides 8 in the branch waveguide type coupler, the frequency interval between a reference mode and a high order mode can be expanded. In the ridge waveguide having projections 4 of which selectional shape is rectangular, the waveguide contraction percentage is reduced in accordance with the reduction of the length of the narrow width surface of the waveguide. When the ridge waveguide having projections 5 of which sectional shape is T- shape, a large waveguide contraction percentage can be obtained even if the length of the narrow width surface of the waveguide is reduced, so that superior characteristics can be obtained over a wide band.

Title: Polyimide laminate body having slipperiness improved
Inventor: KIDO MASAMICHI
IPC: B32B7/02
Filed: 1988-09-09
Abstract: PURPOSE:To improve slipperiness by laminating a polyimide film and an activated fluorine film, and by forming undulation in a specified area on the outer surface of the fluorine film. CONSTITUTION:A polyimide film is obtained from a resin solution of a polyamide acid which is a precursor of polyimide. A fluorine film of which the fluorine content is 20wt.% or above ordinarily, or 50 to 76wt.% preferably, is used. Undulation of 0.03 to 5mum is formed at least on one side of the fluorine film. A sufficient effect of improved slipperiness can not be expected when the undulation is less than 0.03mum, while an adverse effect such as drawing of aid is produced in a subsequent laminating process when it exceeds 5mum.

Title: Radiation optical device for industry
Inventor: MIYATA KENJI
IPC: H05H13/04
Filed: 1987-09-10
Abstract: PURPOSE:To enable large current accumulation by providing a cavity for particle beams to pass through the inside on a particle orbit and erecting such a high frequency electromagnetic field that the resonance frequency may meet the fundamental frequency of a high frequency acceleration cavity in such a mode that the electric field intensity distribution perpendicular to the particle orbit may be inclined on the particle orbit. CONSTITUTION:A cavity 1 in rectangular parallelepiped is arranged on a particle orbit and a particle beam 2 is passed inside this cavity 1. Microwaves are poured into inside of the cavity 1 from an external oscillator 100 through a connected antenna 101, and an electromagnetic field which has high frequency electromagnetic field in TM201 mode for its main ingredient and changes timewise into a rectangle is erected. Since the distribution, in the x direction, of electric intensity in the y direction inside the cavity 1 causes an inclination, high energy particles which pass the outside of the center orbit on the average of time and low energy particles which pass the inside of the center orbit are, respectively, decelerated and accelerated relatively as compared with particles which pass the center orbit. Hereby, the width of energy distribution of particle group becomes narrow, and the expansion of beams based on energy despersion in a closed orbit is restrained and beam-loss caused by the collision to a beam duct is reduced.

Abstract: PURPOSE:To manufacture a lead frame with an aluminum film, which is less expensive and abounds in corrosion resistance and has excellent hermetic sealing properties, by specifying applied voltage to a substrate and relationship with the surface roughness of the coated surface of the substrate of a wire bonding section, etc. CONSTITUTION:Applied voltage B(KV) to a substrate and the surface roughness R(mum) of a lead frame substrate 2 are controlled simultaneously, thus improving the corrosion resistance of an Al film 6. The Al film formed through an ion plating method under the conditions of 0<=(B-C)<2>/R<=45; (in formula, C represents a constant determined by Al film thickness, the material of the substrate, the holding temperature of the substrate, an ionization method, the degree of vacuum and a film formation temperature, and takes a value to 0.0 from -2.0) has excellent corrosion resistance and resin sealing properties and also has superior productivity. Since there is trouble such as the lowering of productivity, it is preferable that applied voltage B(KV) to the substrate is kept within a range of -2.0<=B<=0. It is desirable that the surface roughness R(mum) of the substrate extends over 0.5 or less, but it is preferable that the surface roughness R(mum) of the substrate is kept within a range of 0.05<=R<=0.5.

Abstract: PURPOSE:To reduce the number of parts by using as driving element for a drain valve member form-storing alloy whose transformation point is set to a certain temperature adjacent to but above the freezing temperature so as to cause opening and closing of the valve member by the transformation. CONSTITUTION:A driving element 22 for a valve member 15 having a drain hole 14 is made of form-storing alloy, which is of austenitic structure at high temperatures and of martensite structure at low temperatures. Then, when the ambient temperature of the spring-like member 22 is above the martensite transformation temperature, the valve member 15 closes the drain hole 14, while when it is below the martensite transformation temperature, the drain hole 14 is open. Thus, transformation of the driving element is used to open the valve member, resulting in reduction of the number of parts in comparison with the prior art structure.
