Title: Manufacture of mask rom
Inventor: NISHIKAWA SATORU
IPC: H01L27/112
Filed: 1990-04-18
Abstract: PURPOSE:To write date into a mask ROM by subjecting a ROM structure to H<+> ion implantation and heat treatment before it is furnished with a passivation film. CONSTITUTION:FETs, which are not to be connected with bit lines, are selected out of all the FETs in a mask ROM according to a user program. Hydrogen ions are introduced to the doped channel regions 12 of the selected FETs. The doped channel regions 30 are then heat-treated (28). This heat treatment is carried out to combine the hydrogen atoms, the silicon atoms in a substrate 10, and the dopant atoms in the doped channel regions 30 to make the dopant atoms inactive.

Filed: 1983-06-10
Abstract: PURPOSE:To achieve a printing by a very light operating force by performing a pressure printing (duplication) with an ink roller in the process of withdrawing a moving truck into the machine frame. CONSTITUTION:As a handle 12 is depressed, a moving truck 15 is withdrawn into the bottom of the machine frame 11 through a transmission mechanism of a link 21, a lever 19 and a link 20. As the upper movement thereof is checked, an ink roller 22 rolls pressed on the top of a copying paper on a card placing base 18 passing thereunder to copy a character signal on the card. As the moving truck 15 approaches the final end position of the movement, a contact section 15A thereof 15 hits and pushes an arm 48 of a printing pressure lever 42 to be slid as shown by the dotted line. Consequently, the lower step section 45 gets off the step 47 of the printing pressure lever 42 and an ink roller holder 38 is turned and displaced counterclockwise by the energization of a spring 41 so that the roller 22 rises by a distance to match the difference between the upper and lower steps 45 and 46. Upon the release of the handle 12 from the depression, the handle 12 rises by the spring 41 and returns to the position as shown by the solid line.

Filed: 1983-06-08
Abstract: PURPOSE:To obtain a long life lead-acid battery in which softening or coming off of positive active material is decreased by inserting projections into holes installed on the container side and pressing an electrode plate group by projections. CONSTITUTION:In a paste type lead-acid battery, a projection 3 is screwed in a hole 2 installed on the side of a container 1 and an electrode plate group 6 is pressed by the projection.

Abstract: PURPOSE:To prevent leakage of gas and to obtain a sufficient restricting effect by a tongue member for changing gas flow rate by providing seal members on both side surfaces of the tongue member in such a manner that the seal members are brought into contact with the inside wall surfaces of the turbine housing by means of pressure differentials. CONSTITUTION:A tongue member 4 for changing the flow rate of gas flowing into a turbine rotor has on both side surfaces 4A, 4B seal members 21 of a resilient material.

The seal member 21 is of a sectional configuration having two arcuate portions disposed symmetrically up and down in such a manner that these arcuate surfaces are kept in linear contact with the wall surfaces 2A, 2B of the turbine housing, respectively. And, in the vicinity of a nozzle opening 6 with high static pressure, the seal members 21 are biased to the wall surfaces 2A, 2B and pressure differentials cause the seal members 21 to be attracted toward the wall surfaces 2A, 2B so as to keep sufficient linear contact for improved sealing effect.

Abstract: PURPOSE:To simply and easily obtain a thin metallic film in which the metal having excellent dimensional accuracy is made to remain by forming a thin org. metallic film on a substrate, and radiating electric charge particle beams thereto to decompose the org. metal. CONSTITUTION:An SiN film 2 of a holding substrate is formed on an Si wafer 1 and the thin org. metallic film 4 is formed thereon by spin-coating the org. metal thereon. The charge particle beams are radiated thereto in a vacuum at the acceleration voltage necessary for the thickness of the thin film 4, and the thin org. metallic film 4 is changed to the thin metallic film 4 down to the boundary with the SiN film 2. The thin org. metallic film 4 in the non- radiated part is then dissolved away by a solvent. The thin metallic film 5 formed with the fine wire pattern of the metal is thereby obtd. The above- mentioned metal is preferably Au or Pt and the charge particles are preferably ions. This method is adequate for a field such as X-ray lithography for forming the fine pattern.

Title: Gear driving device and tape recorder
Inventor: UMEZAKI KIYOSHI
IPC: G11B15/665
Filed: 1989-04-24
Abstract: PURPOSE:To reduce the size of the devices in the title and to decrease the collision frequency of parts by providing a worm wheel which is engaged with a worm to transmit drive and can be disengaged therefrom, in which teeth having pointed addenda and the same chordal pitch of addendum are formed only in one direction from the maximum engaging portion. CONSTITUTION:A worm 3 is rotated clockwise by a switching lever 6 to be meshed with a worm wheel 4. Accordingly, the rotation of a motor gear 1 is transmitted through a gear 2, the first gear 3a of the worm 3 and the second gear 3b to the worm wheel 4 to obtain large speed reduction. When a standard tooth form is laterally shifted and the addendum is pointed, the collision of addenda caused when the gear 3b and the wheel 4 mesh with each other can be decreased. Further, when the gear space on the addendum circle of the gear 3b and the gear space on the addendum circle of the wheel 4 are equalized, there is no possibility that two teeth of the gear 3b enter between the teeth of the worm 4 at the time of meshing. If teeth are provided only on the lower side of the maximum engaging portion of the gear 3b with the wheel 4, at the time of collision, they are easy to escape due to contact of teeth most adjacent to each other at the time of engagement.

Abstract: PURPOSE: To provide an intermediate fermenting machine, capable of readily regulating the fermentation time and simple in structure. CONSTITUTION: This intermediate fermenting machine is capable of winding a circulating chain 3 hanging each bucket 2 at a regular pitch around plural chain wheels 5, successively receiving a dough M at a position P by the bucket 2, running the bucket 2 once upward, fermenting the dough M during the reciprocation of the bucket in mutually opposite horizontal directions in an upper fermentation chamber 4b, turning over the bucket 2 at a position R, discharging the dough M, further reciprocating and running the bucket 2 in the horizontal direction in the upper fermentation chamber 4b, rerunning the bucket downward and circulating to the bucket to the position P. When a screw rod 14a is rotated, chain wheels 5a and 5b, together with a slider 7, are moved in the horizontal direction. Thereby, the fermentation time of the dough M can extremely readily be regulated. Since a locking mechanism, etc., for fixing the chain wheels 5a and 5b are not required, the structure is simple.
