Title: Alignment pattern and method of alignment
Inventor: KONISHI MORIKAZU
IPC: H01L21/027
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To improve alignment accuracy and throughput during electron beam exposure, and prevent residue of a resist film. SOLUTION: The alignment pattern 1 is arranged on the surface side of a wafer 11 exposed by an electron beam and is formed of a plurality of patterns 11a arrayed in one direction with their ascending density of alignment toward an alignment center O. When aligning using the alignment pattern 1, an electron beam with a diameter much larger than to the configuration interval L1 of the pattern 11a in the central position O of the alignment direction of the pattern 11a is made to scan the alignment pattern 1 in the alignment direction of the pattern 11a. The relative positioning in the scanning direction between the alignment pattern and the electron beam B can be detected according to the peak position of a signal strength obtained by electron beam irradiation the positioning information of the electron beam irradiation is compensated from this positional relation.

Title: Vertical field-effect transistor
Inventor: KAWAHARA MINORU
IPC: H01L29/10
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To improve the breakdown voltage of a vertical field effect transistor by forming the passage of a current when a drain area and a P-type base area are reversely biased and yield so that the passage can pass through the edge section of the bottom face of a high-concentration P-type base area from the flat section of the P-type base area. SOLUTION: The depth difference L3 between a P-type base area 6 and a high-concentration base area 5A is adjusted so that an avalanche current can flow through the edge section of the bottom section of the base area 5A from the flat section on the bottom of the base area 6 when the difference L3 becomes <=0.5μm. Therefore, current routes 12A and 12Ar become shorter than the conventional example. Since the routes become shorter at the sections passing through the base area 6 having a high resistance, the base potential of a parasitic NPN transistor which uses a low-concentration N-type drain area 8, the P-type base area 6, and the high-concentration P-type base area 5A as a collector, base, and emitter, respectively, becomes lower and the current amplification factor of the transistor drops. Therefore, the breakdown voltage of the transistor can be improved when the transistor is driven in a state where a dielectric load is connected to the transistor.

Filed: 1991-12-16
Abstract: PURPOSE:To automatically and properly prevent the drag of a hydraulic transmission device with a small quantity of parts by providing a brake member in resilient contact with the brake face of a gear, and a piston for causing the brake member to part from the brake face when a hydraulic clutch is engaged. CONSTITUTION:When a selector valve 51 is at a neutral position N, the first and second hydraulic clutches 15 and 17 are drained of oil. Also, the oil chamber 45 of a piston 46 connected to a brake member 44 is drained of oil. Then, the brake member 44 comes in resilient contact with the cone type brake face 43 of the second gear 18, due to a spring 48, and the first gear 16 is thereby braked via the second gear 18 and a transmission means 21 for preventing the concurrent turn thereof with a propeller shaft 3. On the other hand, when the selector valve 51 is selected at a high speed position H or a low speed position L, pressure oil is fed from a pump 52 to each of the hydraulic clutches 15 and 17. As a result, the piston 46 is pressed against the force of the spring 48, and the brake member 44 is separated from the brake face 43, thereby releasing the braking of the second gear 18.

Air is blown into the applied tube 1 that is once baked, from the baking starting end to the baking finishing end, in such a way that it is streamed, so as to bake the applied tube 1 from one end to the other end for each length part. The applied tube 1 which is longer than standard size, can thus be appropriately baked, while an applied tube 1 of standard size can also be appropriately baked.

Title: Printer device
Inventor: MUTO YASUHIRO
IPC: B41J29/46
Filed: 1992-12-14
Abstract: PURPOSE:To prevent image fogging and to restrain the excessive consumption of toner by providing a toner density sensor for measuring the fogging density of toner at the white part of a part out of the user printing area of already printed paper. CONSTITUTION:When the density of the toner at the white part of the already printed paper is abnormal, the part of the toner density sensor output waveform 14a of output from the toner density sensor corresponding to a toner mark 8 becomes a high level signal 21a, and the part thereof corresponding to the white part becomes a low level signal 22a and is higher than a level A. Therefore, a control part judges that a failure of image fogging occurs, and it makes a toner supply target value for controlling toner amount low, and delays the supply timing of the toner fed from a toner hopper to a developing device, so that a T/C value in the developing device is lowered. Thus, the toner density on printing data is made low, the image fogging is prevented and the excessive consumption of the toner is restrained.

Title: Method for pulverizing vulcanized rubber material
Inventor: NISHIYAMA HIDEMI
IPC: C08J11/00
Filed: 1992-12-14
Abstract: PURPOSE:To pulverize waste of a rubber material into finely-divided powder efficiently and continuously in a simple process by applying a shearing force to granular waste of a vulcanized rubber material at a specific temperature. CONSTITUTION:In a method for pulverizing a vulcanized rubber material, a shearing force is applied to granular waste of a vulcanized rubber material at a temperature of 230 deg.C or lower. This is because at a temperature higher than 230 deg.C, a malodor may be generated and the pulverized waste may be thermally fused. When the waste is supplied to a shearing force application device, the waste is granulated to a granular material of a predetermined particle diameter by a granulator or the like for preventing the occurrence of blocking or surging in the loading means of the shearing force application device. If a shearing force is applied after an agent belonging to an anti-blocking agent is added to the waste to be pulverized, the adhesion and cohesion of the rubber material can be prevented.

Filed: 1992-11-20
Abstract: PURPOSE:To suppress the center runout and the face runout of a hub stage effectively with simple constitution by providing a cut hole at one part on the rotation truck of a yoke plate to which the end face of rotor magnet is opposed. CONSTITUTION:A rotor magnet 4 being magnetized in multipole in diametrical direction is held at the inside periphery of a rotor case 5 by adhesion or the like, and the inside periphery is opposed a specified interval part to the outside periphery of a stator core 2, and the lower end face is opposed a specified interval apart to a yoke plate 3. On the other hand, a slot-shaped cut hole 20 is provided at one part on the truck of the rotation of the yoke plate 3 to which the end face of the rotor magnet 4 is opposed, and since there is no magnetic substance at the section of the cut hole 20, the magnetic resistance becomes large there, so it follows that the magnetic attraction decreases. As a result, the rotation of the rotor case is inclined compulsorily, and a rotary shaft 12 inclines by the amount of a clearance to a bearing, and clearance between both ceases to exist, so runout can be suppressed.
