Patent JP-S612413-A (JP)
Title: Am electronic tuning receiver
Inventor: TAZAKI SATORU
IPC: H03J7/18
Filed: 1984-06-15
Abstract: PURPOSE:To suppress the dispersion of stopping sensitivity at an overtuning time and to stop an IF stage AGC at a proper sensitivity by dividing a signal level for driving the IF.AGC into a low level only during autotuning operation to delay the starting point of working of the IF stage AGC by a prescribed time. CONSTITUTION:An input voltage dividing circuit consisting of a resistor R3 and a switching element Q2 is connected between a smoothing signal input line of an LF.AGC driving circuit and the earth. During the autotuning operation of a control IC, the switching element Q2 is turned on. Consequently, a smoothing signal from an AGC smoothing low-pass filter is divided at the rate of about R3/(R2+R3) and the voltage-divided signal is inputted to the IF.AGC driving circuit, so that the starting point (b) of the IF-stage automatic gain control circuit is delayed by the prescribed time. Consequently, the automatic gain control circuit of the IF is in the disabled state at the antenna input level of a required sensitivity setting point (a), so that the output voltage of an S meter is in a linear changing range and the variance of the stopping sensitivity is suppressed.

Abstract: 1502980 Hydro-pneumatic intensifiers REUTI ANSTALT 25 Sept 1975 [10 Oct 1974 4 Aug 1975] 39234/75 Heading F1D In the device shown in Figs. 1 and 2, when compressed air is admitted through a port 11, a piston 8 and rod 9 are moved to the right by the combined action of air acting directly on the piston and by hydraulic liquid acting on the lefthand end 19 of the piston-rod. A free piston 13 transfers the air-pressure to hydraulic liquid and this is forced through ducts 14 to act on the pistonrod 19. When the rod 9 has been moved the desired distance at a relatively high speed with a low-pressure, e.g. up to a workpiece, compressed air is admitted through a port 22. This moves a piston 20 with a rod 21 to the right. After a small displacement, the rod 21 closes ducts 14 and the piston 20 and rod 21 act as an intensifier and move the piston 8 and rod 9 to the right with greater force. Fig. 5, (not shown), illustrates the final position. Fig. 7 shows a simplified embodiment in which the piston 8 is omitted. Air-pressure applied to the port 11' acts on the piston 19 through a free piston 13' and hydraulic liquid which passes through ducts 14'. The intensifier section 20', 21', operates as previously described.

Abstract: PROBLEM TO BE SOLVED: To obtain a two-layer vapor deposition-type magnetic tape which reduces an error rate when it is run on a deck by a method wherein an upper-layer film is formed to be a specific film thickness, the film thickness of a lower-layer film is made thinner than a prescribed value and the difference between an electromagnetic conversion output at a high frequency and that at a low frequency is shifted to the positive side. SOLUTION: As ferromagnetic layers for data recording, a lower-layer ferromagnetic layer 1 and an upper-layer ferromagnetic layer 2 composed of a Co-Ni alloy vapor deposition thin film are laminated on a nonmagnetic base 3, and the film thickness of the upper-layer ferromagnetic layer 2 is set at about, e.g. 60nm. In addition, the film thickness of the lower-layer ferromagnetic layer 1 is changed so as to be divided into four groups of 120±5nm, 105±5nm, 90±5nm and 75±5nm. A frequency characteristic which is expressed by the difference (dB) between an electromagnetic conversion output at 3MHz and that at 1MHz is measured when a magnetic tape is run on an NT deck for data.  As a result, when the film thickness of the lower-layer ferromagnetic layer 1 is made thinner than 120nm as a present thickness so as to be at 90±5nm, the frequency characteristic is shifted to the positive side, and the error rate of the magnetic tape can be reduced when the tape is run on the deck.
