Title: Manufacture of semiconductor device
Inventor: KATAYAMA MASAYUKI
IPC: H01L23/522
Filed: 1991-03-22
Abstract: PURPOSE:To form a multilayer interconnection structure by removing the insulating material on the surface of an underneath layer exposed in an interlayer connecting hole for filling the hole with a conductive material by simpler method. CONSTITUTION:An Si substrate 1 is coated with a layer insulating film 3 through the intermediary of a lower Al wiring layer 2 arranged on said substrate 1 to make a through hole 3a. Next, this substrate 1 is immersed in a hydrochloric acid solution to remove the insulating material 6 existing on the exposed surface of the lower Al wiring layer 2 in the through hole 3a in a uniform state. In such a state, hexafluorine tungsten is reduced using silane gas to selectively deposit the tungsten 4 in the through hole 3a. During the initial deposition process, the hydrogen contained in the fluorine and the reduced gas contained in a metallic material gas induces the chemical reaction to remove the insulation material 6 such as Al2O3 etc., deposited on said exposed surface. Finally, an upper Al wiring layer 5 is formed on the layer insulating film 3 so that a multilayer interconnection structure may be formed through the intermediary of the conductive material 4 deposited in the through hole 3a.

IPC: G01N23/225
Filed: 1983-04-04
Abstract: PURPOSE:To improve the operational efficiency of a goniometer stage for an electron ray apparatus by preventing any unfavorable movement of a sample during the operation of moving the sample by rotating each driving shaft of a mobile mechanism mounted on a slanting table interlockingly with the rotational operation of the slanting table by the same angle as the ratation of the slanting table. CONSTITUTION:In a goniometer stage 70, and X mobile table 7 is installed on an orbit member 6 (installed on the base plate of a sample chamber 2) in such a manner as to be movable in X direction: a Z mobile table 8 is placed on the X mobile table 7; a slanting table 9 for giving a slant to a sample 5 is placed on the Z mobile table 8; a Y mobile table 10 is placed on the slanting table 9 in such a manner as to be movable in Y direction; and a rotary table 11 for giving to the sample 5 a rotation of an axis vertical to the surface of the sample 5 is placed on the Y mobile table 10. When a slant-producing knob 39 is rotated, the slanting table 9 rotates according to the rotation of the knob 39. At the same time, bevel gears 106 and 107, a worm 104 and a worm gear 103 rotate causing a shaft 100 to rotate by the same angle as the above slanting table 9. As a result, the operation of the slanting table 9 does not interfere with either the movement nor the rotation in Y direction and any positional shift of the sample 5 on a sample table 4 is not caused.

IPC: B24D5/10
Filed: 1986-03-17
Abstract: PURPOSE:To perform grinding to provide a deep-sensed surface with high accuracy by furnishing a space for containing a grinding liquid in the body of a grinding wheel, and encapsulating the grinding liquid in the wheel body with a lid for liquid preventive purpose. CONSTITUTION:Grinding liquid 6 is put in a space 1a furnished in the body 1 of a grinding wheel, and a lid 4 is fixed with screws 5 to prevent the grinding liquid 6 from flowing out. If the wheel body 1 is rotated by a shaft 2, centrifugal force is applied to the grinding liquid 6. Because the wheel body 1 consists of consolidated abrasive grains with minute voids provided and is of hyrative nature, the grinding liquid 6 oozes at the surface gradually, and when a work to be ground 7 is contacted, the grinding proceeds under interference of the abrasive grains, wherein used grains are pushed out by and by to be replaced by new grains. Provision of appropriate holes 3 in the wheel body 1 may increase the amount of grinding liquid in accordance with the work to be ground 7. This enables grinding having a deep-sensed surface with high precision.

The data are two-dimensionally spread according to the (g) value and the radical quantity S as is evident from the figure and therefore decision of whether a cancer or not is made posible with good accuracy by drawing the boundary line indicated by the two parameters as shown by, for example, a broken line II and to which side of the line the measuring data positions.
Patent JP-S58173960-A (JP)
Title: Reader of original
Inventor: KATOU MASATOSHI
IPC: H04N1/028
Filed: 1982-04-06
Abstract: PURPOSE:To attain miniaturization of the device and to avoid the S/N characteristic from being deteriorated, by making a linearly polarized light incident to the boundary between a transparent protecting layer covering a photodetection element train on a transparent base and an air layer at an angle close to the Brewster's angle. CONSTITUTION:Only the light in parallel with this paper among the polarized light of a fluorescent lamp 4 transmits a polarizing plate 7, passes through the transparent base 11 and is made incident on the boundary between a transparent protection layer 6 and the air layer. Since the refractive index of the layer 6 is high, the refractive index of the light made incident to the air layer is as shown in Figure. Curves R1, R2 show the change in the refractive index R accompanied with the change in the incident angle theta when the polarization direction is perpendicular to the incident plane and within the incident plane respectively. That is, when the light having the polarization direction within the incident plane is made incident at the Brewster's angle thetaB, the refractive index is 0. Since the illuminated light is made to the linearly polarized wave at the polarization plate 7 and the incident angle from the layer 6 to the air layer is selected as the Brewster's angle thetaB, the reflection light on the boundary is almost zero and the photoelectric conversion with the good S/N characteristic is attained.

SOLUTION: The users use the vehicles in two patterns, i.e., a right pattern where a user uses a rent-a-car in the morning to go to a parking lot 1 near a traffic terminal of a railway, etc., from his house 3 for commutation and then to go back to his house 3 from the lot 1 in the evening (right users), and an inverse pattern where a user uses a rent-a-car in the morning to go to his office 5 of duty from the lot 1 and then to go back to the lot 1 from the office 5 in the evening (inverse users). In the daytime, however, even the temporary users can use the said system in addition to the regular users. In regard to one of typical inverse users, a regional company uses the rent-a-cars for its employees to go to or come back from each traffic terminal in the morning or evening and also uses these cars for business in the daytime respectively.

Title: Motor driver
Inventor: KIKUCHI KAZUNORI
IPC: H02P6/12
Filed: 1995-03-17
Abstract: PURPOSE: To prevent a short circuit current from flowing through a switching element which controls the supply of the drive current of a motor. CONSTITUTION: Transistors 9, 14, and 32 are turned on by outputting drive signals DS2, DR3, DS4, and DR5 on, for example, low level 'L' and drive signals DR1, and DS6 on high level 'H' from a signal generator 2a. A motor rotates, being supplied with a current through a transistor 9, motor coils 20 and 22, and a transistor 14 from a power supply terminal 25. At this time, if the signal level of the drive signal DS2 is inverted, since the transistor 32 is in on condition, the off condition of the transistor 10 is maintained, therefore the short circuit current flowing through the transistors 9 and 10 can be prevented. When the signal level of the drive signal DR5 is inverted, a transistor 40 gets in off condition, a transistor 13 gets in on condition, and the transistor 14 gets in off condition. The short circuit current flowing through the transistors 13 and 14 can be prevented.
