Title: Semiconductor device
Inventor: KIMURA TAKASHI
IPC: H01L21/52
Filed: 1978-01-24
Abstract: PURPOSE: To reduce both the saturation voltage and the heat resistance by attaching the metalized layer on the back of the semiconductor substrate to the package via the Au-Si alloy solder containing the same conducting impurity as the substrate.  
     CONSTITUTION: NiCr layer 8 and Au layer 9 are laminated by evaporation on the back of Si substrate 1 containing the Sb impurity. Then Mn, Mo, Ni and Au are laminated in sequence on the upper surface of beryllia substrate 10 forming part of the package to form metalized layer 11. Layer 11 is heated up to about 400°C via Au-Si alloy solder 12 containing Sb of about 1wt% to fuse the solder and then attached to the package. Owing to existence of layer 11, the high wetting performance is secured in spite of a large area and with no gap produced. Thus, both the heat and electric resistances can be lowered. Furthermore, the Sb is diffused into the substrate from the solder to form an extremely thin and high-density layer onto the attachment surface, thus forming a contact part featuring a high ohmic performance with a low Schottky barrier and with no lowering of the heat conductivity.

Title: Printing device and printing control system
Inventor: KAGEYAMA SAIJI
IPC: B41J29/48
Filed: 1990-01-17
Abstract: PURPOSE:To discharge remaining sheets automatically by checking whether sheets with one side printed remain in an intermediate tray and feeding the remaining sheets from the intermediate tray, if such sheets are present and printing the opposite side to the printed side in the blank mode. CONSTITUTION:If the number of discharged pages is not '0' as a result of checking the number of discharged pages after printing process, the condition of a printer is checked again with a printer engine part to determine whether any remaining sheets are present in an intermediate tray. If there are any remaining sheets, the number of discharged pages is increased. Unless the printer is set in the intermediate tray remaining sheet discharge mode, a routine printing process takes place. On the other hand, if the printer is set in the intermediate tray remaining sheet discharge mode, the intermediate tray is designated as a sheet feed part in the designation process of a sheet feed part and the remaining sheets in the intermediate tray area fed. Next, a single remaining sheet in the intermediate tray can be discharged by printing the rear of the remaining sheet in the blank printing mode. Thus it is possible to detect whether any remaining sheets are present using the printer without causing any load to a host computer and discharge the sheet when an abnormality occurs.

Title: Control method for electron beam current
Inventor: KOJIMA HIDEKI
IPC: H01J37/315
Filed: 1982-01-19
Abstract: PURPOSE:To improve the accuracy of welding starting position in an electron beam welder by applying slight beam current from an electron gun and maintaining a feedback control circuit actuated even when the welding process is not  in operation. CONSTITUTION:The ON/OFF signal of electron beam current is applied to an input terminal 1. When the electron beam current is off, the output of an electron beam setting device 2 is set to be larger than the high voltage leak current of an electron gun section but sufficiently smaller than the beam current during welding. Besides, when the electron beam current is off, an electron current control circuit 3 is operated and slight electron beam current is applied from an electron gun 5 through a circuit 4 consisting of a transformer, a detector circuit, and a carrier AC removal filter. Simultaneously, the output of a lens setting device 6 is fully larger or smaller as compared with that during welding. Thus, the electron beam is fully defocussed by changing the current of an electron lens 8 through an electronic lens control circuit 7. The welding is started by using the output of setting devices 2 and 6 as the welding set point.

Title: Torque control for dc motor adapted to check generation of noise and vibration
Inventor: BAN ITSUKI
IPC: H02P7/29
Filed: 1981-01-21
Abstract: PURPOSE:To reduce noise of the power source by making the energized current waveform of a DC motor correspond to the waveform of the voltage by half-wave or full-wave rectification of an AC power source voltage. CONSTITUTION:Current flowing through a DC motor 5 is detected with a resistance 6. As the output detected rises beyond the upper slice level of a Schmitt trigger circuit 13, it shuts off transistors 14 and 3. This reduces the armature current. As the output voltage of the resistance 6 falls below the lower slice level of the Schmitt trigger circuit 13 with an decrease in the armature current, the transistors 14 and 3 conduct causing the armature current to increase again. An energized current value of the DC motor 5 can be altered with a variable resistance 8. This can reduce noise of the power source to check the generation of noise, vibration or the like.

IPC: B22D11/06
Filed: 1986-01-16
Abstract: PURPOSE:To uniformize thickness is width direction of foil metal at the time of producing the foil metal by rapid cooling as bringing molten metal flowed down from a slit nozzle into contact with a cooling body moving at high speed, by widening the slit gap toward its both ends gradually to make more flow- down rate as approaching to both ends.
