Title: Detection of carbon adherence in coke oven carbonizing chamber
Inventor: KITAHARA HIDEKI
IPC: C10B43/14
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To definitely discriminate whether the rise in the drive load on an extrusion beam driving motor is due to carbon adherence to the oven wall surface or due to damages such as the roughness and/or defectiveness of the oven wall surface. SOLUTION: Acceleration torque and brake torque are subtracted from the motor torque calculated from the electric current value or electric power of an extrusion beam driving motor to determine extrusion torque over the whole extrusion interval: if the peak of the extrusion torque exceeds a predetermined threshold value, it is assessed as 'abnormal', and the extrusion torque over the whole extrusion interval is multiplied to determine extrusion torque multiplication value, which is then divided by the extrusion torque peak value to determine a carbon index; based on the carbon index, it is assessed whether the rise in the extrusion load is due to adhered carbon or due to damages such as the roughness and/or defectiveness of the oven wall surface and bottom surface;  thereby enabling the time of idling operation for adhered carbon removal to be scheduled in advance and the coke oven to be operated safely.

Title: Manufacture of semiconductor device
Inventor: FURUTA KOJI
IPC: H01L21/20
Filed: 1987-02-17
Abstract: PURPOSE:To make the difference in heights between wells nearly equal to zero and to make it possible to form a step required for patterning in succeeding steps, by forming both wells in a substrate by a self.aligning method, thereafter forming an epitaxial layer, and forming both wells in the epitaxial layer in the reverse order of the formation of both wells in the substrate. CONSTITUTION:A silicon nitride film in a P-type well region is removed and ions are implanted. Then, a P-type well region (i) is lower than an N-type well region (ii) by about a half a thermal oxide film. After an epitaxial layer 5 is formed, a thermal oxide film 6 and a silicon nitride film 7 are formed in the reverse order of the initial order. Patterning is performed so as to form an N-type well, and ions are implanted. Then, a thermal oxide film 9 is formed, and the silicon nitride film 7 is removed. Then ions are implanted in the P-type well, and the thermal oxide films 6 and 9 are removed. Then a step is not provided between both wells in the epitaxial layer 5. Thus a double-well structure, in which a step is formed only at the boundary part of the wells, is formed. In this way accurate patterning can be performed with a reducing-projection exposure apparatus. The threshold voltage values of P-type and N-type MOSFETs can be accurately controlled.

Title: Nozzle assembly for continuous alloy manufacturing process and manufacture of said nozzle
Inventor: SHINNPAN WAN
IPC: B22D41/52
Filed: 1992-01-27
Abstract: PURPOSE: To obtain a nozzle assembly in which process control suitable for maintaining a stable skull layer that is hardened to the inside of a nozzle can be used. CONSTITUTION: A nozzle 14 is made of an outer wall 18 that is made of a material such as copper with a relatively high thermal conductivity and a non- contamination material for a melted metal 24 to be machined and treated and is provided with an inner liner 22 that operates as a skull layer. By increasing the cooling heat transfer coefficient in the nozzle, the hardening layer in the steady state of a non-contamination liner material is maintained. The cooling heat transfer coefficient can be increased by reducing the contact resistance of a nozzle outer wall member and the inner liner being created by the non- contamination material. For reducing the contact resistance, the nozzle outer wall member around the inner liner is shrunk and the contact pressure between the members is increased.

Title: Analog type time display of digital watch and analog display type digital watch using it
Inventor: SAITO GORO
IPC: G04G9/00
Filed: 1988-02-18
Abstract: PURPOSE:To fully utilize performance owned by a digital watch and add diverse and aesthetic joy by allowing a digital watch to perform time display which is analogous to that of an analog watch. CONSTITUTION:A decimal numeric (Arabic numeric) of normal analog watch is shown in relief on the surface frame F of a digital watch and a LCD is built into the inside. When the LCD is on, a large number of display lines L1, L2, L3... are displayed in the radius direction instead of normal digital watch. Thus, when the LCD is turned on (energized), display lines T1, T2, and T3 with a specified width appear in accordance with the second, minute, and hour needles of analog watch. In this manner, analog-like time display can be made by rotating the display lines T1, T2, and T3.

Title: Writing system for magnetic tape device
Inventor: TANE KEIICHI
IPC: G11B5/09
Filed: 1985-02-22
Abstract: PURPOSE:To reduce a field-through by decreasing the time change ratio of a write current. CONSTITUTION:A timer 40a outputs a timer output T which comes to a high level only during a certain time t1 from the endge of a write clock WCL. A current control circuit 40 outputs a VS' during the period of the timer output T in synchronizing with the write clock WCL and the write output voltage VS of a V2 thereafter, both of which are supplied to write head drive circuits 41-49. When a write data WD is at a high level, the write current I1 flows. On the other hand, when the write data WD is at a low level, the write current I2 running in the reverse direction of the write current I1 flows in the coil 101 of a write head. A less current flows at the time of inverting period when the write data WD changes from a low level to a high one, and vice versa, and it reaches a normal current after a certain period expires. Accordingly the time change ratio of the current flowing in the write head is decreased, and the field-through can be substantially reduced.
