Title: High frequency component
Inventor: NAGATOMI YOSHITAKA
IPC: H03L7/18
Filed: 1993-11-11
Abstract: PURPOSE:To reduce the adjustment time by providing a resonance electrode pattern on one side of a board and a shield electrode to the other side of the board and providing plural frequency adjustment sections whose adjustment width differs from each other to the resonance electrode pattern. CONSTITUTION:Shield electrodes 26,27 are formed on the surface of layers 22, 24 and an electrode pattern 28 for forming a resonator, an electrode pattern 29 for forming a filter, and an earth pattern 30 to separate them and to be located inbetween are provided the surface of a layer 23. An outer side of a notch window 31c of the pattern 29 is notched and an opposed area of the electrodes 26, 27 to the pattern 29 is reduced, then a capacitive component is reduced, resulting that the resonance frequency gets higher. In this case, since the window 31c is provided to a narrower part of the pattern 29, the resonance frequency is largely chanted. Conversely,when the outer side of the notch window 31a is cut off, since the pattern 29 of the part has a width width, the effect is small and then the variable width of the resonance frequency is decreased.

Title: Leaf-like plate type heat exchanger and its manufacture
Inventor: MATSUMOTO TOSHIO
IPC: F28F3/10
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a plate type heat exchanger for largely reducing pressure loss with excellent heat conductivity, heat resistance and corrosion resistance without fear of leakage. SOLUTION: Thin heat fusible resin to be heat fused with a thickness of 10 to 100 μm or preferably fluororesin film 10 is directly heat fusion bonded to a heat transfer surface 2 of a heat exchange plate 1. Then, two plates obtained by fusion bonding the films 10 are opposed, and a U-shaped sectional member is fusion bonded to a sealing line of the films 10 to form a flexible bag-like structure. Since the sealing line is connected in the flexible bag-like state, no leakage occurs from a unit A or gasket connecting surface. And, the films each having no pinhole are laminated, and hence aluminum plates, metal plated steel sheets or thinner stainless steel sheets can be used for corrosive fluid with high total heat transfer coefficient. Further, its structure is simplified by providing an inlet 15 and an outlet 15' at the U-shaped sectional members of a leaf-like unit.

Title: Electronic azimuth meter
Inventor: SAITO TOSHIHIRO
IPC: G01R33/06
Filed: 1992-10-21
Abstract: PURPOSE:To obtain a small electronic azimuth meter of low power consumption and without its rotation required by arranging three or more sets of magnetic sensors with change of an angle for each of them, for one set of which two directional elements of magnetic resistance are arranged at a relative angle. CONSTITUTION:Magnetic sensors 2 to 4 are placed side by side at a right angle and radially on a base 1, and a magnet 5 is arranged in the central part of the magnetic sensors 2 to 4 in such a manner that the upper side is S-pole, and magnets 6 to 8 are arranged in the outer circumferetial part in such a manner that the upper side is N-pole. Since the elements of magnetic resistance deliver their outputs in an absolute value independently of the direction of magnetism, the offset of magnetism is applied to the sensors 2 to 4 with the magnets 6 to 8, thereby being able to recognize the direction of magnetism to be detected because the outputs become large when the direction of the offset of magnetism is the same as that of magnetism to be detected and the outputs become small when the direction of the offset of magnetism is opposite to that of magnetism to be detected. Also, since the outputs of the sensors 2 to 4 of three sets or sore are calculated to estimate the direction of earth magnetism, the estimation of azimuth can be performed without rotating the sensors 2 to 4. Therefore, the rolling mechanism is not required.

The sector number is increased by only 1 sequentially and as the accessing of all tracks of the track number 0 is ended, the recording/reproduction head is moved in a radial direction of the disc 11 to access all sectors of the track number 2 sequentially from the sector 12 of the sector number 0. This operation is repeated and the accessing of all the sectors is ended to the track number 2L.

Filed: 1989-10-31
Abstract: PURPOSE:To obtain a white level simply and accurately by moving a glass plate when a platen roller is driven and bringing a white colored part of the glass plate to a read position when the platen roller is reversed. CONSTITUTION:When an original 11 is loaded to a reader along a guide 10, an original sensor 9 senses the original, and when a platen roller 1 is driven (reversed) in a direction of the P, the glass plate 12 is moved with friction with the platen roller and an upper end touches an upper side wall of a heat sink and comes to a standstill. A white part exists onto the glass plate at the read position and a white level is obtained by reading the white part. When the platen roller 1 starts forward drive, the glass plate 12 restores to the original position simultaneously as paper feed, the white part of the glass plate 12 is deviated from the read position and the original is read through a transparent part. Thus, the white level is obtained accurately with simple constitution.

Title: Sticking method for projection screen
Inventor: KOJIMA HIROSHI
IPC: G03B21/56
Filed: 1989-10-31
Abstract: PURPOSE:To prevent picture quality from deteriorating by sticking respective screen plates which are reduced in size toward a side which faces outside environment. CONSTITUTION:In an example wherein two lens sheets 1 and 2 are stuck together, the projection-side lens sheet 2 is smaller than the lens sheet 1 positioned on a light incidence side. If the external environment changes, variations in temperature and humidity are uniformed with time gradually in the screen plates, so the screen plate 1 arranged on the light incidence side requires a longer time to have the same conditions with the projection-side screen plate 2 and there is flotation generated between the screen plates. For this purpose, the screen plate 2 is made smaller than the screen plate 1 to preclude the flotation. Consequently, the projection screen which never deteriorates in picture quality is obtained.
