Title: Ground speed detecting device for vehicle
Inventor: NAKATSUKA HIROO
IPC: G01P3/42
Filed: 1982-05-27
Abstract: PURPOSE:To measure directly a ground speed, by converting a Doppler history by an isolated reflection body to a pulse train, and measuring the number of this pulse, and the start point and end point time of the pulse. CONSTITUTION:A coherent radio wave of a transmitter 1 is irradiated from the diagonal upper direction to the surface of a track 8 from an antenna 3, a reflected signal from a crosstie 6 is led to a mixer 9, and it is mixed with a part of transmitting electric power. When the antenna 3 moves by a constant speed (v), a variation output of the expression S is obtained in the output terminal of the mixer 9 (in the expression, (a), lambda, (v), T0 and gamma0 denote a proportional constant, wavelength, a vehicle speed, time when the antenna passes through just above the crosstie, and length of a perpendicular line put down to the crosstie on the track, respectively). When a signal exceeding a threshold level obtained in the beam irradiation width is amplified by a pulse generating circuit 10 which is capable of obtaining a Doppler history by putting a vehicle running distance vt to a horizontal axis, and is converted to a pulse train, the running distance can be represented by the number of pulses. Accordingly, when the necessary time extending from the start point of the first pulse to the end point of the n-th pulse is measured by a counter 11, a speed can be calculated by an operating circuit 12, and acceleration is obtained by measuring a variation rate of said time.

Title: Ion laser tube
Inventor: NAKAZAWA YOSHIO
IPC: H01S3/22
Filed: 1981-06-12
Abstract: PURPOSE:To prevent the bending of the guide bar due to the thermal expansion by a method wherein the guide bar connecting the graphite made anode with the anode terminal outside the glass made enclosure is made a spiral constitution. CONSTITUTION:In the argon laser tube, the guide bar 7' is made a spiral constitution. Consequently even in the case where the clearance between the enclosure and the small tube, anode is eliminated by the thermal expansion of the graphite small tube and the graphite made anode due to the discharging heat of the argon laser tube, the thermal expansion of the metallic guide bar in the axial direction may be absorbed into the changing pitch of the spiral part of the guide bar preventing the guide bar from bending and the laser output from decreasing or stopping oscillation due to the bending of the guide bar blocking the beam stream in the small tube.

Title: Output circuit
Inventor: YAMADA MASANORI
IPC: H03K5/02
Filed: 1995-04-17
Abstract: PURPOSE: To increase the changing speed of the output signal for a noise reduction output circuit. CONSTITUTION: A feedback means 30 decides the potential of an output terminal OUT based on its threshold value and sends the binary feedback signal R, i.e., the decision result of the means 30 to a NAND gate 23 and a NOR gate 24 respectively. If an input signal Sin changes from '0' to '1' the PMOS 25 and 26 are turned on and the potential of the terminal OUT is driven to fast change to the power potential VDD. When the potential of the terminal OUT exceeds its threshold value, the control signal S23 outputted from the Rate 23 is set at '1' and the PMOS 26 is turned off. Therefore, an output signal Sout never overshoots. In this instance, the signal Sout fast rises if the threshold value set by a threshold value setting circuit 31 of the means 30 is approximate to the power potential VDD.
