IPC: H01L29/78
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To remove a short-circuiting cause developed on a sidewall spacer ranging from a diffusion layer of silicide formation to a gate electrode without increasing the number of steps. SOLUTION: Formed on a semiconductor substrate of a first conduction type are an element isolation region, a gate insulating film 203 and a gate electrode 204 of polycrystalline silicon. Formed on a side face of the gate electrode is a sidewall spacer 205 of a titanium nitride film.

Title: Optical disk recording and reproducing device
Inventor: SANADA SATORU
IPC: G11B7/085
Filed: 1988-07-21
Abstract: PURPOSE:To decrease a burden at the time of assembly adjustment by using a one-dimensional position detecting element to output an analog voltage, which corresponds to a head position, instead of an external linear encoder as the position detecting means of a driving part (positioner). CONSTITUTION:In the side of a rail 16 to move a positioner 2, a one-dimensional position detecting element (PSD) 3 is arranged to detect the position of the positioner 2. The PSD3 has a length L, which corresponds to the access area of an optical disk 15 in a radius direction, and width W and receives a beam spot P from a light emitting element which is loaded on the positioner 2. Then, the analog voltage is generated to execute a linear change to the movement of the beam spot P in the case the beam spot P is moved. Thus, the position detecting part of the positioner is easily adjusted at the time of assembly and the movement of the positioner can be exactly controlled to a target position with simple hardware constitution.

Title: Multiplication processor
Inventor: SATOU NOBUYOSHI
IPC: G06F7/527
Filed: 1982-10-18
Abstract: PURPOSE:To obtain the result of multiplication in a high speed, by discriminating whether an addition area is to be shifted after adding a multiplicand thereto or shifted as it is, depending on the content of shift-out bit register. CONSTITUTION:The number of input bit width of an arithmetic processor ALU is set to a counter. When the multiplication is started, the content of a shift register SHR is shifted right by one bit and the least significant bit of the multiplier section is inputted to the shift-out bit register SOR. When this bit is 1, the addition area (high-order side) of the register SHR and the multiplier section (low-order side) are shifted right by one bit again in the next step and the result is inputted. When the register SOR is zero, the high-order side of register SHR is to the register SHR after being shifted right by 1-bit via a multiplexer MPX. In repeating this operation by the number of times of the input bit width of the ALU (until the counter reaches 0), the result of multiplication is set to the entire register SHR.

Title: Valve lifter with thermal spray layer and manufacture thereof
Inventor: SHIMODA KENJI
IPC: F01L1/14
Filed: 1988-07-23
Abstract: PURPOSE:To enhance abrasion resistance and anti-exfoliation by specifying the spraying pressure, and spraying electric current respectively when Fe-C series thermal spray layer is formed by means of arc spray method so as to maintain the thermal spray layer porosity not more than a specified % and the attached thermal spray grains not less than a specified oblateness. CONSTITUTION:After the surface of an aluminum alloy block is treated by shot blasting, a thermal spray layer is formed by arc spraying, then it is proved that the blasting pressure in a range of 5.6-11.2kg/cm<2> is appropriate to maintain the porosity not more than 5%, blow holes increase as grains are not crushed if the pressure it low, and blow holes increase as bouncing becomes vigorous when the pressure exceeds 11.2kg/cm<2>. Also, the oblateness is small if the pressure is low, and the oblateness is large when the pressure is high, proving that the oblateness not less than 0.95 is necessary considering the abrasion resistance and the low abrasion quantity of the counterparts material. Further, when the spray current is made stronger, the hardness of the thermal spray layer increases. And when it is below 100A, the abrasion resistance becomes inferior due to insufficient hardness, and when it exceeds 200A, the arc becomes unstable allowing the temporary existence of undissolved grains in the thermal spray layer and making the grains very hard and easy to attack the counterpart material, thus, 100-200A is found appropriate for the thermal spray current.

Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To enable restarting of engine in the air without deceleration to subsonic speed by providing a restart by-pass duct which by-passes whole engine or fan. SOLUTION: A supersonic aircraft engine 10 provides a re-start by-pass duct 20 for by-passing at least one side of a turbojet enzine 11. The re-start by-pass duct 20 is adapted to by-pass only a fan 12 of the turbojet engine 11. By opening or closing an operated air inlet 22 of the re-start by-pass duct 20 during restraining, part of the air compressed in the air intake 1 is by-passed, and so, the inlet pressure P1 and the outlet pressure P2 can be adjusted to the pressure suitable for starting the turbojet engine 11, thus, the difficulties in restarting are eliminated and without deceleration to subsonic speed, the restarting can be conducted.

Filed: 1989-07-13
Abstract: PURPOSE:To make a member mounting device small in size and simple in structure by a method wherein two or more pawls, which are connected to a contact and made to open or close, are made to close to position a body. CONSTITUTION:A positioning device of this design is provided with two or more pawls 2 which closes or opens as connected to two or more contacts 7 whose mutual space is made wide or narrow corresponding to the rotational angle of a cam 8, where a body 1 is positioned by making the pawls 2 close. As the positioning device concerned is small is size and its component parts are arranged centering on a shaft 11, a member sucking suction shaft 12 is easy to built in an integral structure. A member 20 can be positioned in a process that it is sucked and transferred, therefore a relay table can be dispensed with, so that it is enough that only a set of a transfer arm 15 and a suction chuck is provided. By this setup, a member mounting device can be made small in size and simple in structure.

Abstract: PURPOSE:To prevent the destruction of the anodic oxidation coatings at a corner projecting part by bending a vertical wall in curving shape in the horizontal wall direction, then by forming a joining face by cutting the shape material with the cutting line passing through the bend part of the vertical wall. CONSTITUTION:A bending part 1a'' is formed by bending the vertical wall 1a of a shape material 1 in curving shape so as to direct the tip edge thereof for the vertical wall 1a' at the other part. Then, a joining face 1d is formed by cutting the shape material 1 with the cutting line 1c which is at 45 deg. for 90 deg. corner angle to be formed by the shape material 1, 2.

With this method the destruction of the anodic oxidation coatings on the surface of the corner projecting part can be prevented due to the bending radius of the corner part on the joining face being made possible larger.

Title: Hot dip aluminum alloy coated steel sheet and its production
Inventor: TAKAGI MASAAKI
IPC: C23C2/06
Filed: 1987-07-24
Abstract: PURPOSE:To improve the corrosion resistance and workability on a surface and in end face parts with good balance by biasing the dispersibility of the Al component in a plating layer much to the surface layer at the time of plating a steel sheet with a hot dip coating bath consisting of Zn contg. a specific ratio of Al. CONSTITUTION:The zinc hot dip coating bath contg. 0.3-3.5% Al and the balance Zn is used at the time of producing the hot dip Zn-Al alloy coated steel sheet by a zinc hot dip coating plant. The temp. of the material steel sheet to be advanced into this plating bath is maintained at the temp. lower by 10-80 deg.C than the temp. of the plating bath and the steel sheet is advanced into the bath. The thickness of the steel sheet is larger than the thickness of the plating layer and the temp. thereof is lower than the temp. of the plating bath and, therefore, the plating layer is cooled from the inside surface and the Al component is thickened to the part to be solidified with a delay according to this method. Said component is thus liable to gather on the front layer. The Al component is consequently distributed more in the surface layer in the plating layer and is less distributed at the boundary face with the steel sheet. The plated steel sheet having the excellent corrosion resistance and workability is thus obtd.
