Title: Twin belt type continuous casting method
Inventor: KAJITANI TOSHIYUKI
IPC: B22D11/059
Filed: 1994-07-19
Abstract: PURPOSE:To increase the frequency of generation of nuclei in a short side at the initial solidifying time by forming many dimples on a solidified shell forming surface in a pair of shifting short side blocks forming the short sides of a mold. CONSTITUTION:This twin belt type continuous casting method uses the mold formed of a pair of belts 7a, 7b synchronously shifted with the speed of a cast slab 16 endlessly and a pair of shifting short side (copper) blocks 8a, 8b composed of plural blocks. The frequency of generation of nuclei in the short side at the initial solidifying time is increased by forming many dimples (dh) on each of the solidified shell developing surfaces of a pair of the shifting short side blocks 8a, 8b forming the short side of the mold, and the development of the longitudinal crack can be prevented by decreasing the nonuniformity of the initial solidification to stably cast the cast slab having good quality. Further, the frequency of the generation of nuclei in the short side at the initial solidifying time is increased by executing thermal-spraying of ZrO2 base refractory on the solidified shell forming surface of the shifting short side copper blocks 8a, 8b to form many dimples (projecting parts), and the development of the longitudinal crack is prevented by decreasing the nonuniformity of the initial solidification.

Title: Manufacture of microstrip line
Inventor: DEGUCHI YASUSHI
IPC: H01P3/08
Filed: 1981-10-19
Abstract: PURPOSE:To prevent sparking and to eliminate a breakdown of a substrate, by etching an earth conductor in a ladder pattern, and removing conductive materials on the substrate at slit parts. CONSTITUTION:Conductors 3 and 4 are stuck to both sides of a substrate 2 and the earth conductor 3 is etched in a ladder pattern 6. Then, cloth buffer while turned is pressed against the top surface of the substrate 2 to polish the top surface, removing projections 10- together with the surface layer of the substrate 2. Thus, a conductive materials on the dielectric substrate 2 at slit parts 5 are removed completely, so any spark is not generated even when a large-power microwave for heating is applied to a microstrip line. No breakdown of the substrate 2 due to a spark is therefore caused.

Title: Engine with variable number of cylinders in operation
Inventor: HATSUTORI MITSUO
IPC: F02D13/06
Filed: 1982-09-28
Abstract: PURPOSE:To smoothly switch the number of cylinders in operation without causing large variation in torque in a variable No.-of-cylinders engine in which the number of cylinders in operation is changed by more than one at a time, by performing the change of the operation of cylinders gradually one by one instead of more than one at a time. CONSTITUTION:When a No.-of-cylinders-controller 1 is shifted to the reduced number-of- cylinders operation, the output of said controller 1 varies from ''L'' to ''H'' and it is transmitted to electromagnetic valves 4A and 5A of a cylinder A. Then, fuel injection from an injector 2A is suspended, and a hydraulic tappet 3A is stopped. With this ''H'' signal, terminals P of counters 24 and 32 turn ''H'' level and starts counting the engine revolution pulses. The counter 24 outputs the pulse to a counter 25 for each five counts, turning the Q-terminal output to ''H''. With this, electromagnetic valves 4B and 5B of a cylinder B are operated so that the cylinder B, too, is stopped with the 5-revolution delay as compared with the cylinder A. In addition, when the number of revolution pulses reaches 10, the counter 32 outputs the pulse to F/F33, turning the Q-terminal output to ''H''. Then, electromagnetic valves 4C and 5C of a cylinder C are operated, and the cylinder is C stopped with 10-revolution delay as compared with the cylinder A. With this contrivance, switching of the number of cylinders can be performed smoothly.

Abstract: PURPOSE:To provide a control relay for automobile electric components by providing two coils, two moving iron cores, two yokes, a permanent magnet, two cards, and two moving contact springs and fixed contact springs, and individually operating two sets. CONSTITUTION:The magnetic resistance Ra of moving iron cores 9, 9' and a yoke 5 is nearly equal to the magnetic resistance of the moving iron cores 9, 9' and a yoke 12.

The magnetic flux of the permanent magnet 10 uniformly flows in the iron cores 9, 9'. Since a coil 7 is de-excited, the iron core 9' is kept in the state of the figure (b) by the magnetic flux of the permanent magnet 10, and the iron core 9' is returned to the state of the figure (a) when the coil 7' is de-excited. Another magnetic circuit is not affected in any state of figures (a) through (d), and the operating voltage is not changed.
