Abstract: PURPOSE:To obtain the logical element which can coexist with the analog circuit of high withstand voltage by a method wherein an epitaxial layer is made thicker, the base width of a PNP transistor is reduced using a buried boron layer, and a cut-off frequency is increased. CONSTITUTION:In the diagram, a buried boron (p type) is indicated by 8, and the bottom isolation layer using the buried boron is indicated by 8'. According to this example, the base width of a parasitic substrate PNP transistor Q2 is determined by the distance between the p type region 5 of an NPN transistor Q1 and the buried boron 8, and the base width can be controlled in a constant state by properly changing the heat treatment time even when an epitaxial layer was thickly formed, for example. Accordingly, the epitaxial layer 3 can be formed in the thickness with which the withstand voltage of the NPN transistor Q1 can be satisfied.

Title: Production of optical fiber
Inventor: OHASHI KEIJI
IPC: G02B6/44
Filed: 1990-06-05
Abstract: PURPOSE:To improve the deposition speed of a carbon coating film and increase the density of the film formed on the surface of a bare optical fiber by specifying the temperatures of the surface of the bare optical fiber and the wall of a reaction tube. CONSTITUTION:A bare optical fiber 1 drawn from a heated preform 2 is passed through a CVD reaction furnace 4 to form a carbon coating film on the surface of the bare fiber 1. In the above process, the wall temperature of the reaction tube 5 is adjusted to <=400 deg.C with a temperature controller 6 and the surface temperature of the bare fiber in the reaction tube 5 is adjusted to <=700 deg.C and <1100 deg.C by setting the position of the furnace 4 and adjusting the drawing speed of the bare fiber 1. The thermal decomposition of the raw material gas can be accelerated by increasing the surface temperature of the bare fiber 1, however, the breakage of the bare fiber takes place at >=1100 deg.C. The thermal decomposition of the raw material gas is insufficient and the thickness of the film becomes thin at <700 deg.C. The size of carbon particle can be decreased by setting the wall temperature of the reaction tube 5 to <=40O deg.C to improve the deposition efficiency of the carbon particles on the surface of the bare fiber l. At the same time, the density of the carbon coating film can be improved since the carbon particles are deposited on the surface immediately after generation.

SOLUTION: A treatment liquid, composed essentially of phosphate, colloidal silica, and chromate, is applied to a grain oriented silicon steel sheet in plural times while regulating the coating quantity per time to <=2.5 g/m<2> and baked at 400 to 950 deg.C sheet temp., and the total coating quantity is regulated to (4 to 5) g/m<2> . It is difficult to secure insulating property if the total coating quantity is <=4 g/m<2> , while space factor is decreased if the total coating quantity is >=5 g/m<2> . Although the liquid composition of the treatment liquid to be used is not particularly limited, it is preferable that an aqueous solution or slurry, composed essentially of 3-24 wt.% phosphate, 0.2-4.5 wt.% colloidal silica, and 4-16 wt.% chromate, is used from the viewpoints of the properties of the insulating film and the workability at the time of application.

Abstract: PURPOSE:To change the direction of a paper sheet transferred securely with a simple mechanism and prevent the paper sheet from being jammed by swinging a gate means arranged in a transfer passage for changing the transfer direction of the paper sheet according to normal or reverse rotation of a transfer roller. CONSTITUTION:Transfer rollers 10, 14, 15 are connected to each other with a belt 17 and driven in the direction S1 or S2 with a motor 16 capable of rotating in normal and reverse directions. A gate lever 13 attached rotatably about a rotary shaft 12a is rotated with pulleys 11, 12 and a belt 19 in the same direction with that of the roller 10 up to stoppers 18a, 18b. When a paper sheet is inserted from a point A in the direction of Q1, the motor 16 rotates in the normal direction, the roller 10 rotates in the direction of S1, and the gate lever 13 rotates counterclockwise to guide the paper sheet in the direction of Q2. Then, when the motor 16 is rotated in the reverse direction, the gate lever 13 rotates clockwise to guide the paper sheet in the direction of Q3 to be discharged with the roller 15 in the direction of Q4. With this simple constitution, the gate lever free from paper jamming is formed.

Abstract: PURPOSE:To surely detect a memory by bringing a memory terminal on a cassette side into contact with a sensor terminal on a recording and reproducing device side in the case of housing a semiconductor memory inside a tape cassette having different thickness and case size, detecting the memory and selecting a desired cassette. CONSTITUTION:The arm 105 of a turning member 104 is moved in the desired direction by using a tension spring.

Simultaneously, the turning action of the arm 105 is finished, so that the terminal 106a is press- contacted to the resist part of the memory, and information is detected by a memory detector 101. Thus, the engaging actions of the terminals 106a to 106d are accurately performed even when the distances of the resist parts 9a to 9d are narrowed with the miniaturization of the cassette.

Abstract: PURPOSE:To quickly obtain ultra-minute pattern by employing the high resolution electron beam patterning system with low processing capability for miniature part of specified pattern and the ordinary exposure for the rough area. CONSTITUTION:The negative electron beam resist is coated to the material 8 to be processed on the semiconductor substrate 7. After the position alignment 10, the electron beam is irradiated 11 in accordance with a miniature minute pattern. Then, after mask alignment 10 of the window, the light including the wavelength of 180-300mm. is irradiated to the large pattern region. The pattern 9' is obtained by evelopment and the material 8 is etched using the mask 9'. Since the electron beam is irradiated only to the miniature pattern region, the scanning time is curtailed as compared with that for entire part and the ultra-miniature pattern which has not been obtained by the existing method can be formed. In case this method is applied to the positive resist, since the scanning area is narrow, the scanning time is not elongated and high speed patterning can be realized as in the case of negative resist, making high the degree of freedom of selecting resist material.
