IPC: H01L21/8226
Filed: 1980-04-04
Abstract: PURPOSE:To improve a propagation delay time of the level shift part, by connecting the IIL output collector of the lower layer with the IIL input basd of the upper layer through a diode. CONSTITUTION:A level shifting diode 11 is connected between the collector of the switching (TR)1-1 and the base of the TR1-2, and a diode 12 is connected between the collector of the TR1-3 and the base of the TR1-4, respectively. A level shifting diode 13 is connected between the TR's 4, 5 provided for shifting a signal level from the upper layer to the lower layer, as well, and the load TR14 is connected to the base of the TR4, and the constant-current load consisting of TR's 15, 16, 17 is connected to the base of the TR5, respectively. Since the IIL output of the lower layer is connected to the IIL input base of the upper layer through a diode, when a signal is transferred from the lower layer to the upper layer, the pulse amplitude is not generated more than required due to operation of the diode, a time required for charging the parasitic capacity is reduced, and a transfer time is shortened.

Title: Dc arc welding machine
Inventor: HAGIWARA SEIGO
IPC: B23K9/073
Filed: 1982-03-19
Abstract: PURPOSE:To obtain a titled welding machine that reduces generation of sputter and eliminates influences from outside, by making the wire feeding speed nearly constant and controlling by feeding back the output current when the wire is  short-circuited and controlling by feeding back the output voltage when an arc  is generated. CONSTITUTION:In a DC are welding machine that performs welding by Joule heat at the time of short-circuiting between the wire and base metal and arc heat at the time of opening, the output of a rectifier circuit 1 is supplied to a welding load 3 through an output regulator 2. Short-circuit arc discrimination circuits 6, 7 are provided in the circuit, and short-circuiting between the wire and base metal is detected by inputting signals of an output current proportion signal generator 4, an output voltage proportion signal generator 5 etc. This is compared with a reference signal by a comparator circuit 8, and an adjusting signal is sent to the output regulator 2 through a drive circuit 11. By this way, generation of sputter is prevented by suppressing change of output power when the wire is short-circuited, and voltage is kept constant by eliminating change of arc voltage due to external influences at the time of opening.

IPC: G09F9/00
Filed: 1978-04-17
Abstract: PURPOSE: To increase the contrast of the display pattern as well as to reduce the display area and the power consumption by forming the transparent electrode provided on the upper substrate of the two sheets of substrate holding the liquid crystal between with the thin wire groups.  
     CONSTITUTION: The shape of transparent electrode 7 provided on substrate 1 of two sheets of substrate 1 and 2 holding liquid crystal between is formed with the straight or curved thin wire groups. The A-character pattern is shown by electrode 7 like that in the figure. Thus, the display effective area can be reduced down to about 1/2 compared with the conventional area along with the power consumption proportional to the display area and thus reduced down to 1/2. Furthermore, for the display panel using the FF-type display cell as well as the deflecting plate, the white and black lines are arranged alternately to form the same display pattern of A-character. As a result, the pattern contrast is increased, thus obtaining an extremely thin and clear design of the pattern.

Title: Reaction apparatus
Inventor: FUSE NOBORU
IPC: C30B25/14
Filed: 1988-02-26
Abstract: PURPOSE:To prolong the lifetime of an evacuation route and an evacuation- driving source by trapping a by-product produced inside a reaction chamber in a halfway part of the evacuation route in order to solve a conventional problem of corrosion or the like to be caused by a discharge of the by-product. CONSTITUTION:A liquid trap 10 containing, e.g., water as one example of a trap means used to trap at least a corrosive product out of a product is arranged in an evacuation route 8. When a vacuum pump 20 is driven, a residual gas inside a process tube 1 is introduced into the liquid trap 10 via a heat evacuation chamber 4 and the evacuation route 8. Since HCl as a reaction by-product is water-soluble, it can be dissolved in the water after it has been passed through the trap 10; the HCl can be trapped. It is possible to sharply reduce that the HCl as a toxic gas is discharged to the subsequent route 8; the damage of the vacuum pump 20 can be reduced. By this setup, the lifetime of the route 8 and an evacuation-driving source can be prolonged.

Filed: 1987-03-02
Abstract: PURPOSE:To obtain a measuring system rational even with respect to a quasi- stationary monitor item, by setting a measuring routine so as to make the sampling interval of a measured value at an abnormal time shorter than the sampling interval at a normal time. CONSTITUTION:In performing periodical measurement, it is judged whether a fixed time arrives at the beginning and, in the case of the fixed time, a fixed time flag is set. In a routine 2, it is investigated whether a flag showing the presence of an abnormal item is erected and, if normal, the routine 2 is transferred to a fixed time judge routine 3 and it is judged whether the fixed time flag is erected and, in the case of the fixed time, the routine 3 is transferred to measuring routine 4 to measure each monitor item. Thereafter, a measured value comparing/judge routine 5 is taken and, if normal, a abnormality in the measured value, the abnormal flag of a routine 8 is set with respect to the corresponding item and the routine 6 is taken to display and output an abnormal alarm. As mentioned above, since the measuring loop when abnormality is generated becomes 1 2 7 3 5 8 6 and a time is shortened, the quantity of data increases and the processing operation at the time of the generation of abnormality is facilitated.

Filed: 1991-02-19
Abstract: PURPOSE:To reduce deformation in bending work and make appearance attractive by making a main tube of a pipe material having a vertically long rectangular section, and forming a recess in the center of the outside part and projections longitudinally above and below the recess. CONSTITUTION:Upper left and right main tubes 1 forming a frame of a motorcycle have the front parts bent inside and the front ends butted against a head pipe 2 mounting a front fork and welded thereto. The main tube 1 having a vertically long rectangular section is formed on the central part of the outside surface with a recess 3 and above and below the recess with projections 4 bulging outside to provide a pipe material drawn out longitudinally. When the main tube 1 is worked to bend and set to the head pipe 2, the outside surface of the main tube 1 receives the largest tension. However, since the rigidity is improved by the recess 3 and projections 4 above and below the same, the deformation is prevented. Also, the streaks on the recess 3 and projection 4 provide accents on the appearance.

Abstract: PURPOSE:To eliminate deviation from designed values of widths of a gate electrode and of an interconnection pattern in a field oxide film region having difference in level with respect to an active element region and to improve reliability of an integrated circuit by using photomasks having widths appropriate to the regions to which they are used. CONSTITUTION:If photomasks for an active element region 1 and a field oxide film region 2 having a difference in level with respect to the region 1 have widths of l-f(alpha, h) and l, respectively, widths l44 and l33 of resist patterns will be l44 - [l - f(alpha, h)]-(l-l33)=f(alpha,  h). Therefore, l33=l44. Accordingly, an interconnection pattern in the region 2 and a gate electrode in the region 1 can be formed in correct widths without deviation from designed values. Thus, an integrated circuit can be produced with improved reliability.
