Title: Metal mold for core
Inventor: OOTANI YOSHIO
IPC: B22C7/00
Filed: 1980-02-13
Abstract: PURPOSE: To provide a metallic mold for core which easily expells the air remained in the cavity parts and enable a good core to be obtained by providing a plurality of air vent holes on the circumference of the core-shaped cavity parts provided to half- split molds.  
     CONSTITUTION: After half-slipt molds 1A, 1B are mated, a shell is force-fed by high-pressure force into the core-shaped cavity parts 2A, 2B through the holes formed by the groove parts 3A, 3B for shell blowing. Thereby, the shell is forced into the core-shaped cavity parts 2A, 2B, and the air in the cavity parts 2A, 2B is smoothly exhausted to the outside of the half-split molds 1A, 1B through air vent holes 4A, 4B from the gap between the mating face of the half-split molds 1A, 1B constituting the metallic mold for core. Therefore, the air does not remain in the cavity parts 2A, 2B, and the shell to be force-fed is filled thoroughly to all parts of the cavity parts 2A, 2B.

Title: Synchronizing circuit in data receiver
Inventor: NEGISHI HITOSHI
IPC: H04L7/04
Filed: 1990-01-26
Abstract: PURPOSE:To shorten the synchronization establishing time while enabling the operation at a high speed region by comparing each n-bit output with a reference synchronization flag synchronously with a word clock from a frequency division circuit and outputting a selection signal when the bit output is coincident with the reference synchronization flag. CONSTITUTION:An inputted reception bit clock is frequency-divided into a word length (n) at a frequency division circuit 11 and converted into a word clock and outputted. Moreover, an inputted serial data is received at an n-bit shift register 12 and an n-bit output from the n-bit shift register 12 is latched by a pre-stage latch 13 and an n-bit output of the ore-stage latch 13 is latched by a post-stage latch 14. Moreover, a comparator circuit 15 compares each n-bit output with a reference synchronization flag synchronously with the word clock from the frequency divider circuit 11 and when the output is coincident with the reference synchronization flag, a selection signal is outputted. Thus, the synchronization establishing time is shortened while enabling the operation at a fast speed region.

Abstract: PURPOSE:To form a thin film having equal film thickness and equal impurity density over the whole part by a method wherein a part of partial raw material gas is supplying into running raw material gas flow flowing in a reaction chamber for reaction. CONSTITUTION:When SiH4, O2, PH3 are supplied from respective pipes 2-4 and an SiO2 film doped P is formed on a substrate 21 on a susceptor 20, firstly, a reaction chamber 9 is evacuated under the condition of closing valves 13-16. Next, the susceptor 20 is heated by a high-frequency induction heating coil 8. Next, the valves 13-16 are opened to flow raw material gas from the raw material gas guide port 5 to the exhaust port 7 of a reaction tube 1 and a part of PH3 is also supplied to the running raw material gas flow from raw material gas supply holes 10 through a pipe 12 and manifolds 11. In this way, the partial pressure of the PH3 ranging from the upstream to the downstream of the gas flow in the reaction chamber 9 can constantly be maintained.

Title: Controller for temperature of strip rolled by thickness changeable strip mill
Inventor: KODERA YOSHIKAZU
IPC: B21B37/74
Filed: 1980-02-15
Abstract: PURPOSE: To ensure an aimed finishing temperature of a strip, and to stabilize the product quality, by previously computing the thickness variation in each stand, and by adjusting the water rate sprayed between the stands depending on the variation of mass flow caused by above computed thickness variation, at changing thickness while continuing a hot rolling work.  
     CONSTITUTION: The thickness change computer 1 computes information for changing thickness in the finish rolling work (the adjustment of screw position, the adjustment of rolling speed, and the timing of thickness change), and inputs these data to the screw position controller 3 and the speed controller 4. At the same time, the thickness changing point is tracked between each stand and the timing of spraying water between the stands are determined. Hereupon, the interstand cooling computer 2 receives the thickness variation, the speed variation and the timing of water spray from the computer 1. Then the computer 2 determines the spraying water rate from the variation of mass flow caused by the thickness change and the feed-in side temperature at the finishing stand; this water rateis sprayed on above determined timing. The thermometer 6 installed on the run-out side of the finishing stand effects the feed-back control against the aim temperature on the run-out side of the finishing stand.

Title: Apparatus having automatic pull-in loading device
Inventor: BUIRUFURIITO SHIETSUFUERAA
IPC: G11B15/675
Filed: 1988-01-29
Abstract: It is conventional in relation to automatic retraction mechanisms to position a switch that advances a slide-out compartment in and out either on the front surface of the compartment or behind it at a fixed point inside the device where it can be activated by the compartment, which the operator applies pressure over a short distance to for that purpose. The object of the invention is accordingly to provide a reliable, cost-effective, and user-friendly solution. This object is attained with absolutely already existing components in that the retraction mechanism travels a short distance when pressed, accordingly rotating the rotor component of the motor (1) through the intermediary of the drive mechanism, a rack (3) and pinion (2) and if necessary a belt (4) for example, and causing it to generate electromagnetic force. The resulting pulse is processed in the form of a signal by a simple processing circuit (17) and supplied in the form of a switching command to controls, usually a microcomputer (18). The microcomputer turns on the motor voltage for a specific time and at a specific polarity.

Abstract: PROBLEM TO BE SOLVED: To reduce load that one monitoring device corresponds to fault and to shorten the corresponding time of the fault by connecting the monitoring device with the other monitoring device monitoring a monitoring object so that data can be transmitted and received and switching the monitoring object from one to the other. SOLUTION: The device is connected with the other monitoring devices 17a-17d monitoring the automatic machines (monitoring objects) 11 in respective stores 10a-10c so that data can be transmitted/received. The monitoring of the automatic machine 11 where the fault occurs is switched from one to the other. If the multiple automatic machines 11 with high fault occurrence rate are under the control of the monitoring devices 17a-17d when a monitoring corresponding load monitored in one of the monitoring devices 17a-17d is high, for example, the automatic machines 11 with the high fault occurrence rate are distributed to the other monitoring devices 17a-17d and the loads of the monitoring devices 17a-17d with the high monitoring corresponding load can be reduced.  A uniform monitoring processing can be executed in the plural monitoring devices 17a-17d, the fault corresponding time of the monitoring devices 17a-17d with the high monitoring load can be shortened and service improves.

IPC: G03G15/20
Filed: 1981-02-09
Abstract: PURPOSE:To protect a resin material on the surface of a pressing roll by bringing the revolution of a heating roll to halt after waiting for lowering of the surface temperature of the heating roll. CONSTITUTION:Turning-on a switch of a copying device heating of each rolls in a fixing device is started. Detection of respective 180 deg.C and 60 deg.C surface temperature of a fixing roll 2 and a pressing roll 3 is caused to indicate the ready for fixing. Next, a sensor 15 detecting the lowering of the surface temperature of a roll 8 down to 165 deg.C is acted to bring both of the revolution of the roll 3 and the roll 8 to halt. Then a sensor 13 detecting the lowering of the surface temperature of the roll 3 down to 135 deg.C energizes at the same time a halogen heater 9 and a motor 38 to regulate within a prescribed temperature range. The partial concentration of heat is thereby avoided. Thus a resin material on the surface of the roll 3 is protected even if the removal of pressing contact is not taken among the rolls.
