Title: Branching filter
Inventor: UENO MORIAKI
IPC: H01P1/205
Filed: 1987-02-20
Abstract: PURPOSE:To securely separate signals which are in two close frequency bands by setting the electrical angle of a second comb line band-pass filter(BPF), where the signal of a second frequency band which is higher than a first frequency band passes through, smaller than the electrical angle of a first comb line BPF. CONSTITUTION:The electrical angle theta2 of the BPF 20 for reception, which is the second comb line BPF where the signal of receiving frequency band which is the second frequency band higher than the first frequency band passes through, is set smaller than the electrical angle theta1 of the BPF 10 for transmission which is the first comb line BPF where the signal of the transmitting frequency band which is the first frequency band passes through. For example, if the length l2 of the inner conductive film 42, 42... of the BPF 20 for reception is set short, the electrical angle theta2 of the BPF 20 for reception is smaller than the electrical angle theta1 of the BPF 10 for transmission because the length l2 is short. Thus, the skirt characteristic of the lower side of the BPF 20 for reception becomes sharp, so that the range where the pass frequency bands of the BPF 10 for transmission and 20 for reception overlap becomes narrow or they do not overlap.

Title: Manufacture of printing head
Inventor: HOSHINO HIROSHI
IPC: B41J2/235
Filed: 1989-02-16
Abstract: PURPOSE:To reduce adhesion of cutting refuse when an end of a yoke is cut and to remove said refuse easily by an air gun or the like by providing a bypass plate in a freely detachable manner at the other end of said yoke to which is attracted an armature. CONSTITUTION:When an end of each of an upper yoke 2 and a lower yoke 3 is to be cut, a bypass plate 7 is inserted into a groove formed in a yoke base 6. Consequently, a magnetic flux flowing from an end of the upper yoke 2 to an end of the lower yoke 3 tends to flow much to the bypass plate 7 in a magnetic circuit formed by the upper yoke 2, lower yoke 3 and a magnet 1. A magnetic flux comes to hardly flow in the ends of the upper yoke 2 and lower yoke 3. Accordingly, the ends of the yokes 2 and 3 are cut during this time. After the dust or refuse is removed, an armature 4 is installed and the bypass plate 7 is removed.

Abstract: PURPOSE:To obtain a power MOSFET having a small ON resistance and a fast switching speed by forming an oxide film by a LOCOS method, forming the thickness of the thick oxide film to a specific value or less, and forming a dense oxide film thin on a channel forming part and thick on a region therebetween. CONSTITUTION:A channel layer 3 is covered with a mask of a nitride film, a drain layer 2 between the channel layers is etched, and a thick oxide film 53 is formed by high temperature oxidation.

The formations of a source electrode 7 and a drain electrode 8 are similarly to a conventional method. If the thickness of the film 52 on the layer 2 is so limited as to become 4000Angstrom  or less in this MOSFET, when the thickness of the film 51 is 1000Angstrom , for example, in 500V breakdown strength n-channel MOSFET, the rise of an ON resistance may be limited to approx. 10% as compared with the case that the thickness of the oxide film is uniform.

Title: Color filter for reflection type liquid crystal display device
Inventor: HANEDA AKIO
IPC: G02F1/1335
Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent color filter pixels from being stripped or dissolved by using a photosensitive color resin compsn. having a small content of color pigments and containing a UV absorbent. SOLUTION: A photosensitive color resin compsn. having a small content of pigments and containing a UV absorbent is used for the formation of color filter pixels. The content of pigments is <=20 wt.% to 100 wt.% of the solid content of the photosensitive color resin compsn. containing an UV absorbent, and the content of the UV absorbent is 0.5 to 5 wt.%. UV rays are absorbed and attenuated by the UV absorbent before the rays reach the lower layer of the color filter pixel film. Therefore, the photosensitive color resin compsn. near the color filter substrate under the color filter pixel film is not excessively hardened. This prevents peeling of a hardened film due to decrease in the adhesion strength with the color filter substrate which occurs when the film is excessively hardened.

Abstract: PURPOSE:To obtain a clear print with high density, by a method wherein the pigment concentration per unit area of a heat-fusible ink layer of a thermal transfer sheet used in an N-times mode process is set to a concentration represented by a specified formula. CONSTITUTION:An N-times mode process is a thermal transfer process in which the feeding velocity (N) of a transfer recording material is set to be greater than the feeding velocity (N') of a thermal transfer sheet when thermal transfer by a thermal head is conducted by superposing the sheet and the recording material on each other. The pigment concentration per unit area, P(g/m<2>), of a heat-fusible ink layer of the thermal transfer sheet used for the N-times mode process is set to be P'XN/N', where P' (g/m<2>) is the pigment concentration per unit area of an ink layer of an ordinary thermal transfer sheet. For example, where N/N'=2, P is set to 2P'. By this, high-density printing can be performed even in the N-times mode process. The pigment concentration of the ink layer can be enhanced by a method wherein the concentration of a pigment in a wax ink is preliminarily enhanced, or a method wherein the thickness of the ink layer itself is increased.
