Title: Method for forming conductive part in micropore through hole of circuit board
Inventor: KOKUBU KATSUNORI
IPC: H05K1/11
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To realize a method for forming conductive parts in a micropore through hole of a circuit board which can appropriately improve connection reliability of conduction and can reliably respond to micropore wiring patterns, by making the interconduction between inner layer wiring patterns and outer layer wiring patterns as small as possible with a multilevel construction. SOLUTION: A through hole which is partially blocked by an inner wiring pattern 4 is formed by a laser means from one outer-layer conductive layer 2 for bringing the inner wiring pattern 4 and the outer-layer conductive layers 2 and 5 of both sides into conduction by through hole. Another through hole which is partially blocked by the inner wiring pattern 4 and is displaced from the above through hole within an acceptable range is formed from the other outer conductive layer 5 by a laser means in the same way for forming a through hole 6 with steps, and a through hole plating layer 7 is formed finally.

Title: Reflection type screen
Inventor: SATO HIDEO
IPC: G03B21/60
Filed: 1989-07-20
Abstract: PURPOSE:To obtain a bright screen and to watch an image very clearly in a bright room by arranging transparent beads which can converge light all over the surface of a light reflection layer and using silver ink as the reflection layer. CONSTITUTION:The light is transmitted through the transparent bead which can converge the light, but the light which ought to be transmitted to the back surface of the bead 4 is reflected by the reflection layer 2 into the bead and exits toward an incident surface again because the reflection layer 2 is provided on the back surfaced of the bead 4. Therefore, the back surface of the bead 4 becomes the reflection surface. For example, the bead 4 having 100mum diameter is used and the silver ink for screen printing is used as the reflection layer 2, then the silver ink is thickly painted and dried on the foundation cloth of the back surface. By using the silver material which is excellent in reflection characteristic as the reflection layer 2, the bright image is offered even in the case of the image projected on a screen from a projection type television projector which is somewhat short of the light quantity of a light source.

Title: Illuminator, scanning aligner and device manufacturing method employing them
Inventor: HINAI OSAMU
IPC: G03B27/54
Filed: 1994-07-19
Abstract: PURPOSE:To uniformize the exposure of a photosensitive substrate surface and transfer an excellent pattern image over the entire range of the sensitive substrate surface by a method wherein the illumination position related to the scanning direction of light pulse to be applied next is changed in response to the intensity of light pulse applied previously. CONSTITUTION:The scanning speed of a reticle 10 and a semiconductor substrate 12 are kept constant. Further, pulse intervals of exposure light from a light source are kept constant and the amount of exposure of each pulse is monitored. When the amount of exposure of pulse is larger than a desired amount of exposure, at the time of the next pulse application, the position of an illumination region is displaced in the opposite direction to a scanning movement direction of the reticle 10 from a position at the time of pulse applied previously. Thus, the exposure time period is relatively reduced.

Title: Manufacture of optical head device
Inventor: ASADA JUNICHI
IPC: G11B7/22
Filed: 1990-07-16
Abstract: PURPOSE:To form the grating of minute pitch by forming the grating by utilizing a bright/dark pattern obtained by irradiating a specific optical mask with a luminous flux. CONSTITUTION:On a transparent substrate 14b, a transparent film 14a having a prescribed periodic structure is formed. In this case, film thickness d1 of the transparent film 14a is set as indicated with an expression I. In this regard, lambdaand (n) denote wavelength of a light source, and a refractive index of the transparent film 14a, respectively. By such an optical mask 14, a phase of light is inverted by pi in the part in which the transparent film exists and in the part in which it does not exist. In such a way, as for a light amplitude distribution on the substrate 17, the light amplitude comes to zero in a boundary part of a pattern, and it comes to a distribution whose contrast is satisfactory. Also, since light whose phase is shifted by pi is allowed to interfere directly without interposing a light shielding film, the contrast is satisfactory, and a grating a minuter pitch than that of a conventional phase shifting method can be formed.

CONSTITUTION:A driving means 7 driving an induction-heating coil 6 is controlled by an ON/OFF control means 14 as follows: As a result of the comparison by a temperature gradient comparing means 11, if the detected temperature gradient is larger than the preset temperature gradient, it is turned to OFF from ON, then it is turned to ON when the preset time elapses after the temperature descent start is detected by a temperature descent detecting means 13 immediately after it is turned to OFF, then as a result of the comparison by a temperature comparing means 12, it is turned to OFF if the temperature detected by a temperature detecting means 3 is larger than the preset temperature, and to ON if smaller. When the load quantity of an object to be heated is small, the maximum temperature of the object to be heated can be set to the preset temperature.

IPC: G01N27/12
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To shorten the waiting time till a pollution is detectable at the time of starting and make detectable a gas after starting in a polluted atmosphere by intermittently turning on a heater in a power saving mode, renewing a reference value based on the output of a gas sensor in heating, and starting the detection of the gas based on the reference value renewed in the power saving mode, in a normal mode. SOLUTION: The heater 4 of a gas sensor 2 is intermittently turned on in a power saving mode, and a reference value is renewed based on a gas sensor output in heating so that the reference value can be renewed substantially similarly to a case of the heater 4 under a continuous turned-on state. The reference value can be thus renewed with a little power consumption. In the gas is detected under the reference value in moving to a normal mode, the waiting time till enabling the detection can be shortened. When moving to the normal mode in a polluted environment, the reference value corresponding to the clean environment is obtained so as to enable the gas detection. In this constitution, the gas detection can be performed even if moving to the normal mode in the polluted environment.

Title: Perpendicular magnetic recording medium and its production
Inventor: AKAMATSU TAKAYOSHI
IPC: G11B5/706
Filed: 1986-08-15
Abstract: PURPOSE:To provide the titled recording medium which has the small coercive force in the film thickness direction, does not generate cracks and can maintain the large magnetic anisotropy in the film thickness direction by incorporating cobalt and nickel into a perpendicularly magnetized film in such a manner that the number of atom ratio thereof is within a specific range. CONSTITUTION:The number of atom ratio of the cobalt and nickel incorporated into the perpendicularly magnetized film is within a 55:45-40:60 range. The fine structure of the film is distinct if a gas having low chemical activity is introduced therein, but the coercive force increases if the fine structure is distinct. The generation of such fine structure is adequately suppressed by adding the nickel at a relatively high ratio to the film up to the 55:45-40:60 range of the number atom ratio of the cobalt and nickel. The generation of cracks is thereby prevent and the coercive force in the film thickness is decreased to <=1,000 Oe.

Filed: 1994-07-22
Abstract: PURPOSE:To prolong life by specifying material of a circular rubber member in a rubber fitting torsional damper, and thereby improving durability, and sliding torque. CONSTITUTION:A torsional damper is prepared by press-fitting a circular rubber member to a portion between opposed peripheral surfaces of a hub provided on a crank shaft and a circular mass concentrically arranged near an outer periphery thereof.
