Title: Gate turn-off thyristor
Inventor: KOGA TAKEHARU
IPC: H01L29/74
Filed: 1990-04-06
Abstract: PURPOSE:To draw out a gate current equally from each gate contact terminal and to prevent a turn-off breakdown by making the cross section of a connecting conductor be a rectangle and by making the length in the vertical direction larger than the width in the direction parallel to the main surface of a semiconductor substrate. CONSTITUTION:The cross section of an inner gate lead 51 is made to be a rectangle, while the length in the vertical direction is made to be large as 3mm and the width 1mm in regard to the main surface of a semiconductor substrate. Thereby the inductance from a point 50 of connection with a central gate contact terminal 41 of the lead 51 to the fore end of the terminal 41 is made equivalent substantially to the one from this point to an outer peripheral gate contact terminal 42. In other words, it is possible to equalize the inductance from the point of connection of the terminal 42 with the terminal 41 to the fore end of each terminal without reducing a force of pressure contact of an electrode body with an electrode on the main surface of the semiconductor substrate. According to this constitution, it is possible to draw out a turn-off current equally from both of the terminals 41 and 42 and thus a breaking current can be improved.

Filed: 1983-05-23
Abstract: PURPOSE:To allow a pickup to reach a destination by one jump by converting the difference in address between the current position and destination of the pickup directly into the number of tracks that the pickup jumps over. CONSTITUTION:A track number converter 11 converts the address difference between the current position and destination into the number of tracks, a conversion table register 12 is stored with a conversion table between addresses of preset principal points and the numbers of tracks, and a coefficient register 13 is stored with gradient coefficients for approximation among the principal points. The converter 11 uses the data in the registers 12 and 13 when calculating the number of tracks that the pickup jumps over. Namely, the register 12 sets addresses of principal points t1-t5 to calculate and store the corresponding numbers n1-n5 of tracks on the basis of a specific equation. Further, the principal points are approximated with straight lines and gradient coefficients a1-a5 are stored in he register 13. The converter 11 reads necessary data out of the register 12 and 13 and performs arithmetic to calculate the number of tracks to be jumped.

Title: Electrically conductive roll for electroplating
Inventor: HASHIMOTO YOSHIAKI
IPC: C25D7/06
Filed: 1980-07-05
Abstract: PURPOSE: To increase the hardness, toughness and strength without deteriorating the electric conductivity by adding Mo and Cr to Ni, further adding W to harden the matrix, and hardening the austenite matrix with corrosion and wear resistances through a solid soln.  
     CONSTITUTION: This roll consists of, by wt., ≤0.1% C, ≤1.5% Si, ≤1.5% Mn, 14W19% Cr, 13W18% Mo, 3W6% W, ≤6% Fe and the balance essentially Ni. As the Mo content is increased, the corrosion resistance is increased remarkably, yet >18% Mo deteriorates the resistance. W improves the corrosion resistance, yet it is added to improve the wear resistance, and when the W content exceeds the upper limit, the corrosion resistance is deteriorated. Cr forms the matrix together with Ni, Mo and W and provides passivatability, yet >19% Cr deteriorates the corrosion resistance. C, Si and Fe are inevitable, and the contents are made as low as possible. Mn improves the stability and hot workability.

Title: Image recorder
Inventor: DOI ATSUHIRO
IPC: G03D9/00
Filed: 1987-04-15
Abstract: PURPOSE:To prevent a temperature in a device from raising excessively, by providing an air feeding fan for feeding the open air for cooling to the upper part of a heating part for executing a heating development processing or executing simultaneously a heating development and a transfer, and an exhaust fan for exhausting the cooling air after cooling more than the feed air quantity of a suction fan. CONSTITUTION:While a transferred image receiving material is being taken out to a take-out tray 54, exhaust heat by a heater 46 is diffused in a developing and transfer means 28, but this dissipation is emitted to the upper part of the developing and transfer means 28 through a heat insulating material of the periphery of a developing and transfer part. In this state, when cooling air from a suction fan 56 is fed to the upper part of the developing and transfer means 28, this exhaust heat is cooled by the cooling air, and the cooling air which has exchanged heat for the exhaust heat is exhausted to the outside by an exhaust fan 62. By making the exhaust quantity of this exhaust fan 62 larger than the feed air quantity of the suction fan 56, the influence by exhaust heat of the heating part is reduced, and it can be prevented that the temperature other than that of the heating part in the device raises excessively.
