Title: Semiconductor memory
Inventor: OHIRA TAKESHI
IPC: G11C11/34
Filed: 1987-10-06
Abstract: PURPOSE:To raise the gate potential of a drive transistor by generating the potential at least higher than the potential which is that made of adding a supply voltage to the threshold potential of a transfer transistor, and impressing that potential on the gate of the transfer transistor. CONSTITUTION:A prescribed decoder 1 is selected and the potential being almost the supply voltage is supplied to the output line of the decoder 1 and transferred to the gate of the drive transistor T6 without reducing the potential of the output line by the transfer transistor T5 on which the gate voltage being leastwise it's own threshold potential Vth higher than the supply voltage is impressed. Therefore, the gate potential of the drive transistor T6 is set to the required high potential (the supply voltage). Thus the drive transistor T6 can raise the charging potential of a word line by showing it's driving ability to the maximum.

IPC: F23D14/18
Filed: 1985-11-11
Abstract: PURPOSE:To make a uniform distribution of temperature within a room by a method wherein a catalyst combustion part of an entire circumferential radiation type having a wide combustion area is vertically arranged and a convection flow fan is arranged above the catalyst combustion part. CONSTITUTION:A blower device 12 arranged above a catalyst combustion part 1 has a fan motor 17 within a fan case 16. Fuel gas supplied from a fuel supplying nozzle 3 into a gas chamber 2 is diffused within a thermal holding material 5 heated, whereby its temperature is also increased and then the gas is diffused at an entire circumference within the combustion catalyst 7. At this time, the catalyst reaction is promoted over an entire circumferential surface of the combustion catalyst 7 with the diffused combustion air from the surrounding air, with the result that the catalyst combustion is made stable. When a regular stable combustion is continued, a radial strong infra-red ray is discharged from the entire circumferential surface of the combustion catalyst 7 outwardly. In turn, the air flowed through the incoming air port 15 under an air feeding force of a fan motor 17 is blown from a blowing port 14 opened at an outer circumference of the top plate 13 laterally or inclinedly and downwardly. Hot air stream is formed at a part below a circumference of the catalyst combustion device to cause a uniform distribution of a room temperature to be attained.

IPC: G06K7/12
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To enable an optical reader which can detect the arrangement position of a latent-image mark formed of a phosphorescent body layer by detecting the afterglow emitted with the mark by using a photodetecting means, while irradiating the mark with exciting light by using a projecting means, to perform mark detection with superior S/N ratio, without having to provide a wall surface for partitioning a light irradiation position and a photodetection position from each other, even when both positions are arranged close to the mark. SOLUTION: While an angle α of intersection of the optical axis L1 of the projection means 14 with the latent-image mark 12 is set obliquely from the orthogonal direction, the angle β of intersection of the optical axis L2 of the photodetecting means 16 to the latent-image mark 12 is set between the angle αand the direction orthogonal to the latent-image mark 12. Consequently, the light irradiation position and photodetection position on the latent-image mark 12 can be arranged close to each other, and mark detection with superior S/N ratio can be performed, without having to provide a wall surface shielding both positions from each other.

Title: Ceramic ball machining method and device
Inventor: SUZUKI YASUO
IPC: B24B37/02
Filed: 1989-09-28
Abstract: PURPOSE:To process many ceramic balls at one time by bringing free abrasive grains in contact with ceramic balls effectively by mounting a machining bath which contains suspension consisting of free abrasive grains dispersed in high molecular solution and ceramic balls and a stirrer which stirs suspension in the machining bath. CONSTITUTION:When a stirring blade 12 is rotated, ceramic ball W which has a specific gravity smaller than that of metal ball is simply dispersed and floats in suspension 10 together with free abrasive grains. Particularly, projection section on the surface collides intensively with free abrasive grains and is ground to approach a true ball gradually. In this case, suspension 10 which contains free abrasive grains having comparatively large grain diameter is used, and it is changed over into suspension 10 which contains free abrasive grains having small grain diameter as the grinding process advances. Then, it is possible to approach ceramic balls W to true balls due to changes of number of contact and contact position of abrasive grains for ceramic ball W. Their surfaces become smooth. Thus it becomes possible to machine many ceramic balls W at one time.

Title: Crossing type jack
Inventor: DAARIRU ERU ENGERU
IPC: B66F3/22
Filed: 1993-09-17
Abstract: PURPOSE: To form a light groove-shaped part using a small quantity of material by drawing the center sections of tetragons to form a tapered shape after forming channel bars from a raw material having the side face sections connected to both ends of the center sections of the tetragons. CONSTITUTION: After stamping out channel bars 19 from a steel plate, when the end sections 43 and 44 are drawn outside and broadened by drawing the center sections 29 of the channel bars 19 in the direction of side face sections 31 and 32, the material of the center sections 29 is reduced in thickness due to drawing, and the longer the center section 29 is drawn, the more the thickness is reduced. That is, in the cross sections near the center section of the channel bar 19, the thickness of each of the center sections 29 is more or less reduced more than the thickness of each of the side face sections 31 and 32, and in cross sections adjacent to the end sections 43 and 44, the center sections 29 are drawn, becoming thin. In either before or after this drawing process, the side face sections 31 and 32 are bent orthogonally to the center section 29. This makes it possible to form a channel bar with tapered section using a small quantity of material and lighten the channel bar.

Filed: 1990-09-22
Abstract: PURPOSE:To fasten by a desired fastening torque, by stopping the feeding of power to a rotating driving source, when a detected value reaches a set value corresponding to a preset fastening torque. CONSTITUTION:A ring gear 19d of a differential planetary gear mechanism 19 is turned in the reverse direction to a driver bit 23 with a reaction force torque being received according to the load applied on the driver bit 23, and this reaction force torque of the ring gear 19d is detected by a torque detection part 28. When the output signal of the torque detection part 28 reaches the set value corresponding to a preset fastening torque with the thread being fastened in this state, a stoppage signal is output to a rotation driving source 5 from a fastening completion detection part 30, the rotation driving source 5 is stopped, and the fastening work is completed. At this time, the rotation of the driver bit 23 can also be stopped immediately without receiving the effect of inertia together with the stoppage of the rotation driving source 5, because of the driver bit 23 being rotated at low speed. Consequently it can correctly be fastened at a desired fastening torque value.
