Title: Electronic watch with tuning meter
Inventor: WATANABE MINORU
IPC: G10G7/02
Filed: 1981-03-27
Abstract: PURPOSE:To achieve a simple and accurate tuning by indicating a difference on a liquid crystal display unit between the input frequency of a counting circuit and a reference frequency of a reference frequency memory circuit as compared with a frequency comparator circuit. CONSTITUTION:A time reference signal oscillated with a quartz oscillator circuit 1 is divided 2 and decoded into a numeral with a decoder 3 and a liquid crystal display unit 5 is driven with a driving circuit 4 to indicate a time. With the operation of a mode selector switch 6, a normal time indication mode is switched over to a tuning mode to memorize a reference frequency corresponding to the pitch name desired for tuning into a reference frequency memory circuit 8 while the pitch name is displayed or a device 5. A sound wave of a music instrument for the tuning is input into a receiving section 9 and amplified 10. Then, a square wave of a fundamental frequency of the input signal is shaped with a waveform shaping circuit 11. This square wave is counted for a fixed time with a counting circuit 12 and the fundamental frequency of the circuit 8 and the input frequency of the circuit 12 are compared with a frequency comparator circuit 13. A difference thus obtained is indicated on a device 5.

Title: Method of treating rail with heat to heighten rupture strength of neck of said rail
Inventor: MASUMOTO KOUKI
IPC: C21D9/04
Filed: 1979-04-13
Abstract: PURPOSE:To provide a rail, the rupture strength of whose neck is high, by heating the top and side of the head of the rail and its neck above the A1 transformation point and thereafter rapidly and uniformly cooling the heated portions in a coolant. CONSTITUTION:A heater 6 is provided on the transfer line of a rail R so that the heater surrounds the top 2 and side 3 of the heat of the rail and its neck 1. After the entire head of the rail R is heated to a temperature above the A1 transformation point, almost equal quantities of a coolant are ejected from a cooler 7 onto the top 2, the side 3 and the neck 1. These portions are thus uniformly and rapidly cooled so that no excessive tensile stress remains in the neck 1 of the rail. This results in making the rupture strength of the neck 1 of the rail much higher than that of a conventional heat-treated rail.
