Title: Digital signal transmitting system
Inventor: TAKAI HITOSHI
IPC: H04L27/18
Filed: 1985-12-26
Abstract: PURPOSE:To prevent the waveform distortion due to a multi-path by mounting and transmitting alternately the same data to the first and second frequencies. CONSTITUTION:The first oscillating device 4 oscillates a frequency f1 and the second oscillating device 5 oscillates a frequency f2 respectively. Balance modulators 6 and 7 balance-modulate the differential coding data inputted to an input terminal 2 by the above-mentioned frequency. Switches 8 and 9 select alternately the output of the balance modulators 6 and 7, and output the signal modulated by the frequency f1 at the first half part of the same time slot and by the frequency f2 at the last half pat to a synthesizing device 10. At the receiving side, the sent signal is separated by the frequency, the first half part is delayed by the half time slot and synthesized with the last half part. Thus, since the part overlapped by the direct wave is decreased even when the delaying wave exists, the waveform distortion due to the multi-path can be miniaturized. The frequency and the time diversity effect can be obtained.

Title: Method for controlling ram of hydraulic punch press
Inventor: MIYAMOTO TAKAMI
IPC: B30B15/18
Filed: 1993-10-28
Abstract: PURPOSE:To always perform punching in a vibration convergence state of a table, and to attain stable working accuracy even when the standby height of a ram, is variously changed. CONSTITUTION:A ram reachable time (t) required when a ram 5 descends from an ascending standby position to a prescribed punch position (a position (H0) where a punch and a material come into contact with each other), is calculated from the data of a ram height (h) and a ram descending speed (v) between both positions. When comparing this ram reachable time (t) with a vibration convergence time (t0) after positioning a metal plate feed table, in case that the reachable time (t) is shorter than a convergence time (t0), the start of the descending of the ram 5, is allowed to delay from T1 at the time of positioning by a difference in time (t0-t) of both times. When the reachable time (t) is longer than the convergence time (t0), the ram 5 is immediately allowed to start descending.

Title: Amplifier gain control circuit
Inventor: ROBAATO II MAIYAA
IPC: H03G3/30
Filed: 1989-11-14
Abstract: PURPOSE: To eliminate a transient effect of resistance element switching by synthesizing a signal, which has a prescribed waveform repeating at a speed higher than the reciprocal of two-fold higher frequency in a prescribed frequency range, with a representative level signal and correcting the value of a switching resistance element in accordance with the difference of a standard threshold. CONSTITUTION: A waveform generator 130 oscillates a repeat waveform like saw tooth waves having a speed higher than two-fold 1/fu where fu is the cut-off frequency of an LPF 120. The repeat waveform and the output level representative signal pass a capacitor 133 and a resistor 139 respectively and are coupled and are inputted to an input terminal 137 of a comparator 135. When the voltage at the terminal 137 is lower than a standard voltage Vref the comparator output closes a switch 140. Since the switch 140 is switched at a speed higher than two-fold frequency fu, the transient effect due to the switch 140 is eliminated from the amplifier output by the LPF 120. As the result, the switching transient effect is not included in the output signal from the LPF.

Title: Trim material
Inventor: TANABE KAZUO
IPC: B32B7/02
Filed: 1990-10-30
Abstract: PURPOSE:To obtain a trim material which is light in weight and superior in stability of a molded form and acoustic insulation properties, by a method wherein the title material is constituted of a base molded into a predetermined form by impregnating a flexible foamed polyurethane sheet with synthetic resin or a synthetic resin precursor and a cork layer to be stuck to the base. CONSTITUTION:A trim material is constituted of a base molded into a predetermined form by impregnating a flexible foamed polyurethane sheet with synthetic resin or a synthetic resin precursor and a cork layer to be stuck to one side or both the sides of the base. Since shaping properties are given to a flexible foamed polyurethane sheet by impregnating the flexible foamed polyurethane sheet with a curable substance such as synthetic resin or synthetic resin precursor, molding becomes possible. However, the title material is lack of rigidity by singleness of the flexible urethane sheet and inferior in stability of a molded form. The cork layer possesses rigidity though the same is light in weight and the flexible foamed polyurethane sheet is improved drastically in the stability of the molded form by being reinforced by sticking the cork layer onto one side or both the sides. Since air is contained in the cork layer, the cork layer performs an acoustic action along with the flexible foamed polyurethane sheet.
