Title: Bulk aluminum using product
Inventor: YASUHARA SUMIO
IPC: B21D53/00
Filed: 1986-08-30
Abstract: PURPOSE:To secure the safety forever by replacing the current life, production equipment, etc., based on the products made of stone, iron, wood, etc., with aluminum products and structures. CONSTITUTION:A product can be formed with pouring-in the molten Al if an Al material is used. Since the combination is performed in the order of its flowing-in and a rapid cooling is performed, it is unnecessary to spend a long term like a concrete and the immediate use of the product is available from its completion date. The flank in less quantity will do as well. The product having a permanent stability can be made with easy working since it is unnecessary to add a weight piling to the upper part at forming time, to give the application of force by giving a vibration and to weaken the seam with a reinforcement, etc., by destroying it to the contrary by trying to close it.

Title: Video tape recorder
Inventor: TSUJI MASAKI
IPC: H04N5/91
Filed: 1986-08-29
Abstract: PURPOSE:To always set the optimum compensating quantity of a frequency characteristic even when the frequency characteristic of a tape is changed, by detecting the frequency characteristic of the tape, and varying the peaking quantity of an equalizer circuit according to a detected output. CONSTITUTION:The optimum compensating quantity of the frequency characteristic can be always secured by supplying the detected output of an AGC detection circuit 15 also to the equalizer circuit 13, and varying the peaking quantity of the circuit corresponding to the frequency characteristic of the tape. In other words, when the frequency characteristic of the tape is changed, the output level of a lower side wave component Sc is not changed, but, the output level of a carrier component Su is changed. Therefore, the output level of a reproduced FM signal is also changed when the frequency characteristic of the tape is changed. By performing envelope-detection on the reproduced FM signal, and changing the peaking quantity of the equalizer circuit 13 setting the detected output as a control signal, the compensating quantity of the frequency characteristic can be prevented from being changed even when the frequency characteristic of the tape is changed.

Filed: 1990-07-31
Abstract: PURPOSE:To complete in a short time the procedure from measurement of threshold input current to judgement of hysteresis by reducing the number of times of changing supply current to a light emitting element. CONSTITUTION:First, a variable i for calculation is initialized at a controller. Next in the second step, current IFL smaller than the threshold input current is impressed to a light emitting element 1 using a supply current impressing means 11. In the fourth step, the maximum judgement value IFHLmax and the minimum judgement value IFHLmin of the down side threshold input current IFHL are calculated with a calculation means 13 in the controller side. Finally, it is judged whether the up side threshold input current IFHL, output voltages V01, V02 are in the determined range. Thus, the number of times of changing supply current to the light emitting element 1 is reduced, and then the time from the measurement of the threshold input current to the judgement of hysteresis is shortened.
