Patent JP-S61214447-A (JP)
Title: Manufacture of semiconductor device
Inventor: SUGIMOTO KENJI
IPC: H01L29/78
Filed: 1985-03-19
Abstract: PURPOSE:To realize the separation of adjacent transistors by a smaller occupied area by utilizing the side walls of a gate electrode for effecting the separation of the transistors. CONSTITUTION:A gate electrode 1 is formed on an element active region on a semiconductor substrate 4 and an impurity layer for isolation 5a is formed by using said gate electrode 1 as a mask. The surface of the layer 5a is coated with an insulating film 5 for isolation and is made flat. By anisotropic etching, the insulating film 5 deposited on the gate electrode 1 is removed to leave only the insulating film 5 present between the gate electrodes 1. The gate electrode 1 is patterned again to be made into a predetermined shape. As the final step, an impurity diffusion layer 2 is formed. Because the insulating film 5 as well as the gate electrode 1 functions as a mask, the impurity diffusion layer 2 can be obtained.

Title: Electrophotographic type recording device
Inventor: IIDA MASARU
IPC: H04N1/04
Filed: 1985-03-20
Abstract: PURPOSE:To prevent a shift in printing position by switching the output of a semiconductor laser 2 for control according to the output signal of a period detecting circuit which detects a period until a specific time is elapsed after the tailing edge of a synchronous signal obtained by a synchronous signal detecting circuit is detected. CONSTITUTION:The unmodulated output of the semiconductor laser 2 is controlled to an optimum value set so as to obtain the best print quality by a variable resistance 13C at every photosensitive body 1 according to its photosensitive characteristics in a period until the specific time is elapsed (until a scan within a printing range is completed) after the tailing edge of the synchronous signal obtained by the synchronous signal detecting circuit 6 is detected. In a synchronous signal detection period obtained by a period detecting circuit 12, on the other hand, the output of the semiconductor laser 2 is controlled to a value characteristic to a laser printer which is determined by resistances 13d and 13e regardless of the kind of the photosensitive body 1. Thus, the synchronous signal is detected by laser light with a constant output characteristic to the laser printer, so there is no shift in printing start point even if the unmodulated output of the laser light is varied.

Filed: 1978-05-19
Abstract: PURPOSE: To do away with an approach distance of a primary side inlet piping by setting eccentrically against a casing body a pipe bundle where secondary fluid flows and an inlet nozzle.  
     CONSTITUTION: The center line of the primary coolant inlet piping is agreed with the center of an inner cylinder 3 and a pipe bundle 15, but is set eccentrically with an upper body 2. Under this structure, the flow velocity is big at the part of small space capacity formed by the inner cylinder 3 and the upper body 2, and it is small at the large space. Therefore, at the direction where the maximum flow rate is inclined after an elbow passing, the space formed by the inner cylinder 3 and the upper body 2 is narrowed to increase the flow velocity there; thus, pressure loss increases at a window part 13 of the inner cylinder and decreases on the side of larger space. The flow into the pipe bundle part 15 is thus uniformed, and the approach distance after an elbow passing in primary coolant piping can be done away with.

Title: Rotor conductor casting method of cage rotor
Inventor: FUJIMOTO NOBORU
IPC: H02K15/02
Filed: 1978-05-19
Abstract: PURPOSE: To prevent the occurrence of abnormal vibration of the rotor by employing the casting method such that gates of as many as the number of poles or its integral multiple are provided to the side of mold at regular intervals.  
     CONSTITUTION: When the number of poles is four, for example, the number of gates is made four as well, and the gates are provided to the circumference of mold at regular intervals. The distribution of secondary current is locally disordered by the influence of resistance distrubution of the rotor conductor, but the distribution of secondary current with respect to interpoles is symmetrical. Therefore, when the secondary current is symmetrical, the flux of space produced by the current is symmetrical, the mode of exciting force proportional to square of the flux becomes a four-degree mode Y which is balanced in terms of vectors, the primary mode and a drop of the mode degree are not developed by the combination of these numbers of poles and gates. In the four poles armature, it is proper that the number of gates is four or its integral multiple.
