Title: Pipe made of resin
Inventor: ONARI TAKASHI
IPC: F16L9/12
Filed: 1987-12-09
Abstract: PURPOSE: To simplify the mounting operation and raise efficiency by arranging nut insert holes on a cylindrical body of resin, forming bolt insert holes throughout the nut insert holes and forming engagement members for stopping the rotation of nuts in the nut insert holes. CONSTITUTION: Nut insert holes 2, 3 are arranged on an outer peripheral surface of a cylindrical body 1 of resin, which are equally spaced from the end surfaces 1a, 1b. Through holes 4, 5 are arranged from the end surfaces 1a, 1b throughout the nut insert holes 2, 3. In the nut insert holes 2, 3, rotation stopping engagement members 6 are formed on the end surfaces of the openings of the bolt insert holes 4, 5. The rotation stopping engagement members 6 engage the outer peripheries of the hexagonal nuts screwed with the bolts inserted in the bolt insert holes 4, 5. As a result, the strength with respect to the clamping force of the bolt is raised so that the pipe is highly reliable. As operation can be completed by manipulating the bolt only, the operation efficiency is raised.

Title: Electric coffee pot
Inventor: OBATA HIDEO
IPC: A47J31/44
Filed: 1987-12-09
Abstract: PURPOSE: To obtain tasty coffee by a method wherein a hot water storage tank is freely rotatably arranged and is nearly cylindrical with a bottom adjacent to a delivery port of a water passing device, provided with a plurality of partition walls inside while a plurality of bleeding holes are provided on the bottom part thereof. CONSTITUTION: A heater 17 is electrically energized and water in a tank 11 begins to drip intermittently from a delivery port 21 through a water passing pipes A14 and B19. When the hot water tank 22 is so set that a first tank 22a is located right under the delivery port 21, boiled water dripping from the delivery port 21 is stored in a first tank 22a. As the hot water storage tank 22 is mounted by being inclined, when the boiled water is stored in the first tank 22a to a certain quantity, the total balance of the center of gravity is broken and the hot water tank 22 rotates. The boiled water stored in the first tank 22a drips at a time through the bleeding hole 25a provided on the bottom part to pour on coffee powder set in a filter chamber 20.  During the period, the boiled water dripping from the delivery port 21 is received by a second tank 22b and none thereof pours on the coffee powder thereby realizing a steaming process for the extraction of coffee.

Title: Method for forming image
Inventor: ITO YOSHIKUNI
IPC: C09D11/326
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To suppress occurrence of beading by giving ink containing surfactant of a range of predetermined wt.% under the condition that an ink amount per unit area and unit time becomes a predetermined value or less. SOLUTION: Ink containing at least surfactant of a range of 0.2 to 5.0wt.% is given under the condition that an ink amount per unit area and unit time becomes 8×10<-3> mg/mm<2> .sec or less. In a printed image using the ink containing 0.1wt.% of the surfactant amount, no beading occurs, but in a printed image using ink except it, the beading easily occurs as the surfactant amount is increased, and the image is deteriorated. If the ink amount printing per unit area and unit time is set substantially to 8×10<-3> mg/mm<2> .sec or less, occurrence of the beading can be effectively alleviated. Thus, an apparatus for suitably controlling the ink amount to be printed per unit area and unit time on a medium to be recorded is used.

IPC: G02B6/122
Filed: 1999-11-02
Abstract: PROBLEM TO BE SOLVED: To obtain an optical transmission/reception module where two photodiodes can be integrated on a single chip. SOLUTION: The optical transmission/reception module 111 is comprised of a waveguide substrate 112, where a V-shaped optical waveguide 116 is formed, and a dual PIN-PD(photodiode) 123 which is arranged so as to face a filter 115 arranged in a turning-back position of the optical waveguide 116 in one end part of the substrate 112. An optical signal, received by a common port optical fiber 118, passes the optical waveguide 116 and is transmitted through the filter 115 and is received by a reception port 124. Light emitted from an LD 122 for transmission is branched, and some passes through the optical waveguide 116, is reflected by the filter 115 and is inputted to the common port optical fiber 118, and others will not pass through the optical waveguide 116 but is scattered and is inputted to a monitor port 125.  Since two PDs are formed on a single chip, the module is made small-sized and lowered in cost.

IPC: B01D1/00
Filed: 1986-12-29
Abstract: PURPOSE:To enhance corrosion-resistant and release-resistant properties by coating a section containing a zirconia sintered crucible for evaporation used for concentrating uranium of an isotope separation device with a yttria corrosion-resistant layer. CONSTITUTION:An evaporation crucible 10 for separating isotopes is provided with a box-type crucible base constituted with zirconia sintered material, and a corrosion-resistant layer 13 coated with flame sprayed yttria is provided in a containing section 12 opened up on said base.

Title: Driving device for plasma display panel
Inventor: UEDA TOSHIO
IPC: G09G3/291
Filed: 1989-11-30
Abstract: PURPOSE:To decrease loss currents so as to suppress a power loss and to reduce electric power consumption by interposing a constant current element between a voltage line for maintenance pulses and a resistance voltage dividing circuit so that the supply current to the resistance voltage dividing circuit for generating a writing voltage is maintained constant. CONSTITUTION:The constant current element 201A is interposed between the voltage line L 10 for the maintenance pulses VS and the resistance voltage dividing circuit 102. The current flowing from the voltage line L 10 for the maintenance pulses VS to the 2nd resistance voltage dividing circuit 102 is held constant in such a manner and, therefore, the current flowing to a 1st transistor Q 10 is confined only to the current derived from the excess voltage of a 1st capacitor as a power source. The loss currents are eliminated in this way, by which the power loss is averted and the electric power consumption is reduced.

Title: Capacitive pressure sensor and its manufacture
Inventor: NAKAJIMA HIDESHI
IPC: G01L1/14
Filed: 1993-12-14
Abstract: PURPOSE:To shorten a manufacturing process, to improve a size accuracy and to stabilize product characteristics. CONSTITUTION:A diaphragm 1 is obtained by forming a resist mask on a substrate of a single crystal silicon and etching from one surface to form a recessed part 4, a thin part 5 and a thick part 6. A thickness of the thick part 6 is the same as that, of the original silicon substrate. The thick part 6 is formed more thick than in a conventional product, and therefore hardly deformed even when a pressure is impressed. A parallelism to an electrode 9 is maintained and a capacity is stabilized. The electrode 9 facing a pressure sensitive part consisting of the thin part 5 and thick part 6 is formed at a recessed part of an upper glass plate. A recessed part 11 of a base glass plate 3 sets a movable area for the thick part 6, so that the diaphragm 1 is prevented from being broken when not smaller than a rated pressure is impressed. Since the diaphragm 1 is obtained by etching only from one surface, the thin part 5 and thick part 6 can be controlled easily in size, that is, a size accuracy is improved and characteristics of the product are stabilized, a manufacturing process is greatly shortened, and a manufacturing yield is improved.

When the P value exceeds 40, the Q dumping effect of the vertical deflecting coils 1 and 2 is increased, while the frequency dependent property of convergence is reduced. And when the P value is less than 3, the effect of the Q dumping is reduced, making liable to generate a wavy ringing, and the frequency dependent property of convergence is increased. Consequently, the generation of wavy ringing can be prevented sufficiently, and the frequency dependent property of convergence can be reduced sufficiently.
