IPC: G03F1/60
Filed: 1990-09-10
Abstract: PURPOSE:To prevent particles from being applied to the surface of a substrate by a method wherein, when the substrate is bonded to a substrate bonding stand, the substrate is pressed toward the substrate bonding stand by using compressed air. CONSTITUTION:A substrate (a silicon wafer) 7 is piled up on the smooth surface of a reinforcement body (a substrate bonding stand) 2 in such a way that an epoxy-based sheetlike adhesive 6 is sandwiched; the reinforcement body 2 is housed in a recessed part 11 at a heater plate 10. Then, an electric current is applied to a heater 9; the adhesive 6 is heated to its hardening temperature via the reinforcement body 2; compressed air 15 is jetted to the surface of the substrate 7 from the rear surface of a pressurization utensil 16. The pressure force by which the compressed air 15 presses the substrate 7 is set to a magnitude, e.g. 8kg/cm<2>, which is required to bond the substrate 7; compressed air 15' supplied to the pressurization utensil 16 is set to a definite pressure (e.g. 100kg). At this time, the pressure force of the compressed air 15 is set by adjusting a faced gap delta between the substrate 7 and the pressurization utensil 16 within a range of, e.g. 3 to 10mum. In order to cool the adhesive 6, cooled compressed air 15b is jetted from the pressurization utensil 16 instead of the compressed air 15.

Title: Four-head recording and reproducing system
Inventor: TAKIZAWA YOSHIHIKO
IPC: G11B27/032
Filed: 1988-09-27
Abstract: PURPOSE:To reduce the reproducing error rate of a subcode after post-recording by recording a subcode to be post recorded so as to coincide with the center line of a magnetic recording face obtained at the time of recording other recorded data. CONSTITUTION:A pair of magnetic heads A', B' for post recording are a arranged so as to be shifted upward only by height DELTAt corresponding to a deviation DELTAl between the center line (c) of the magnetic recording face of a recording/ reproducing magnetic heads and the tracking center line c' of a recorded track. When the subcodes are post-recorded by the magnetic heads for post recording, the post-recorded subcodes SUB1, SUB2 are recorded on the same center line (c) as the data recording positions of the already recorded PCM and ATF areas. Consequently, the subcodes can be prevented from being post recorded in the state shifted downward from the data recording positions of the PCM and ATF areas by DELTAl.

Abstract: PURPOSE: To reduce the cost, size and thickness of the EL driving circuit by dividing Y electrodes into two parts on the panel side through a capacitor and connecting two X electrodes so as to draw out n/2 X electrodes. CONSTITUTION: Each two X electrodes 1 are connected so as to draw out n/2 X electrodes and Y electrodes 2 are divided into two parts on the panel side through the capacitor 4.

Title: Shinbone side component for artificial knee joint
Inventor: MATSUNO NOBUO
IPC: A61F2/38
Filed: 1990-09-11
Abstract: PURPOSE:To provide a shinbone side component for an artificial knee joint allowing easy setting and strong initial fixing, and coping with a sinking phenomenon by causing a sleeve nut slidable in the axial direction of an anchor bolt and rotatable to have a thread section of larger pitch than anchor bolt threads on the external surface thereof. CONSTITUTION:An anchor bolt 10 is rotated in an arrow direction, thereby causing the rotation of a sleeve nut 12 coupled to the surface of the smooth section 10b of the bolt 10. The anchor bolt 10 is thereby made to enter a shinbone 3. The anchor bolt 10, when further rotated, may deep enter the shinbone 3. Actually, however, there is a pitch difference between the threads of the sleeve nut 12 and an upper thread section 10a, and a base plate 6 is pressed onto the cutout section of the shinbone 3, thereby preventing the further progress of the anchor bolt 10. As a result, a fixing force can be generated. If a shinbone side component 4 sinks, only the base plate 6 and anchor bolt 10 can sink, leaving the sleeve nut 12 in place, because the anchor bolt smooth section 10b and the sleeve nut 12 are slidable on each other.

Title: Generating system for microprogram bit pattern
Inventor: AOKI HIROMICHI
IPC: G06F9/28
Filed: 1987-09-24
Abstract: PURPOSE:To shorten a time required for execution of a microprogram by separating a part of a microprogram field from other parts and decoding this separated part via a logic circuit having a specific algorithm for generation of a microprogram bit pattern of the next step. CONSTITUTION:A part of a microprogram field is separated as a microprogram bit pattern generating field (G field). Then a microprogram bit pattern including the G field where the production of a microprogram bit pattern of the next step is previously taken into consideration is read out of a memory part 1 and sent to a register 3. A decoder 4 decodes the partial output of the register 3 corresponding to the G field via a logic circuit constituted based on a fixed standard. This decoded output serves as a part or the whole of the microprogram bit pattern of the next step so that the microprogram of the next step is produced without reading a bit pattern out of the part 1. In such a way, the time required for execution of a microprogram is shortened.
