Filed: 1984-05-15
Abstract: PURPOSE:To record a luminance signal without applying the time base compression and to obtain a color video signal recording system capable of preventing the deterioration of picture quality by modifying an angle of winding a tape and separating recording areas for the luminance signal and chrominance signal. CONSTITUTION:A magnetic tape T comes into contact with a rotating drum D in a range of 180 deg.+60 deg.. As shown by a recording track of the magnetic tape T in the figure, when one rotating head A records a recording area enclosed by diagonal lines, that is, the area corresponding to the winding angle 60 deg., the other rotating head B is caused to record the next track simultaneously. At this time, luminance signal components are not subjected to the time base compression, and recorded as 1Y, 2Y, 3Y... for every field, while chrominance signal components are subjected to the time base compression, and recorded sequentially as 1C', 2C', 3C'... in a part corresponding to the tape winding angle 60 deg.. Thus the luminance signal and chrominance signal are recorded at different positions on the tape, and the deterioration of the picture quality caused by the mutual interference can be prevented.

Title: Temperature controller of injection molded product
Inventor: KIMOTO HIDETOSHI
IPC: B29C45/26
Filed: 1990-04-11
Abstract: PURPOSE:To uniform the temperature of each part of products and to lessen the possibility of deformation by partitioning a mold into hot, medium, and cold parts and by providing cooling pipes having control functions corresponding to the respective parts. CONSTITUTION:In the dwelling step, the temperatures of the respective parts of hot, medium, and cold 2, 3, and 4 in a mold are measured by sensors 7, and an arithmetic controller 9 calculates the cooling time from a measured temperature of the hot part to a pre-inputted mold-release temperature by the finite difference calculus with a linear equation of thermal conductivity. Simultaneously, the controller 9 calculates required flow rates of cooling water so that the measured temperatures of the medium and cold parts may become the same mold-release temperature in the same time as the cooling time calculated from the equation, thereby allowing cooling water to flow from cooling tank T to cooling water pipes A-F corresponding to the respective parts. This arithmetic/control is repeated and corrected to enhance temperature control. The above-mentioned process can uniform the temperature of each part of products and lessen warps and deformations.

Abstract: PROBLEM TO BE SOLVED: To enable uniformly and quickly raising the temperature in the surface of a board to be treated, and improving the quality and the throughput, by spraying specified heated gas on the board to be treated passing the vicinity of a heat source, and compensating the temperature rise of the board to be treated. SOLUTION: When a board W to be treated is heated with the heat radiation from a heat source 2 and thermally treated, specified heated gas is sprayed on the board W to be treated passing the vicinity of the heat source 2, and temperature rise of the board W to be treated is compensated. For example, when the wafer W is lifted and moved to a thermal treatment position C, the wafer W is moved at a comparatively fast speed wherein in-plane temperature difference is hardly generated. When the wafer W passes a specified position B, the gasline of a second gas introducing inlet 6b is controlled to be a very small flow rate, and the gasline of a first gas introducing inlet 6a is controlled to be a flow rate wherein the central part of the wafer W can sufficiently accept thermal conduction from the treatment gas.  Therefore, the in-plane temperature difference of the wafer W can be reduced or dissolved as much as possible.

Filed: 1983-05-31
Abstract: PURPOSE:To detect an illegal intruder with high precision by arranging plural couples of projectors and photodetectors longitudinally so that every other beam directions are opposite. CONSTITUTION:There are two signals S32 and S23 which are projected on and photodetected by a couple of adjacent cylindrical bodies. An inverter 6 inverts the output signal S32 of a photodetector R32 which generates a high-level signal in photodetection, and the inversion output is sent out to a monostable multivibrator 8. The monostable multivibrator 8 detects the rising of the output signal of the inverter 6 to output a one-shot pulse having an about 1 second pulse width. This monostable multivibrator 8 is provided because an intruder does not cut off upper and lower beams L23 and L32 at the same time all the time. An AND circuit 10a sends out a high-level output when the beam L32 is cut off firstly and the light beam L23 traveling in the opposite direction between the same cylindrical bodies within a specific time after said cutoff.

Abstract: PURPOSE:To reduce influence when the direction of magnetic field has shifted against the tube axis by maintaining the distance between the photoelectric face and dynode within specific dispersion range of the diameter of photoelectric face or the inscribed circle of a rectangular photoelectric face. CONSTITUTION:The distance between a photoelectric face 8 and a dynode 10 is maintained within 1/5 of the diameter of said face 8 or the inscribed circle of a rectangular photoelectric face.

A planar dynode 10 having diameter of 68mm. is arranged in parallel while being separated by 1.5mm. from the meshed anode 9 and anode 9 in this order. Consequently the distance between said face 8 and dynoe 10 is about 8mm. which is about 1/9 of the diameter of said face 8.

Therefore, the shaft tube 3 can be continuously bent in response to the fluid pressure.
