Title: Light pulse separation circuit
Inventor: INOUE YASUSHI
IPC: G02F3/00
Filed: 1996-05-01
Abstract: PROBLEM TO BE SOLVED: To provide a light pulse sepn. circuit which allows the fetching of a desired signal channel at the same light frequency as the light frequency of an original pulse train out of the time multiple light pulse trains. SOLUTION: Time multiplex light (frequency fs) is inputted through a polarization controller 1 and a coupler 2 to a nonlinear medium 3. The same period light (frequency fp1) as the light pulse signal drawn out of the time multiplex light and continuous wave (frequency fp2) are outputted from pumping light sources 4, 5, are subjected to polarization multiplexing by a polarization beam splitter PBS 6 and are inputted to the nonlinear medium 3. The polarization state of the time multiplex light is made coincident with the pumping light 2 (the light of the continuous wave of the frequency fp2) and is intersected orthogonally with the pumping light 1 (the light of the continuous wave of the frequency fp1). The light of the same frequency as the frequency of the time multiplex light is generated by four light wave mixing with the nonlinear medium 3 by setting fp1+1p2=2fs.  The light having the polarization state intersecting orthogonally with the time multiplex light is outputted from the output of the nonlinear medium 3. Only the time separation light is fetched by the polarization beam splitter PBS 7 and the optical fiber 8.

Title: Air pump
Inventor: MATSUDA YOUICHI
IPC: F04B45/053
Filed: 1981-07-16
Abstract: PURPOSE:To obtain the stable linear operation and improve the durability in a captioned pump by connecting a connection rod with a piston guided and held to a cylinder and the piston with an elastic operation member such as a bellows and the like. CONSTITUTION:When an electric motor 1 is operated and an eccentric rotation body 11 is given force by a shaft 12, a piston 16 is vertically reciprocated via a connection rod 13b. When the piston 16 is reciprocated, a cap 24 fixed at its top is vertically reciprocated, and a bellows 24 is vertically expanded and contracted as a whole as interlocking with the cap 24. In this air pump, only linear reciprocation is taken out from the reciprocation of the rod 13b by a cylinder 15 and the piston 16 and transmitted to the bellows 26. Consequently, the beloows 26 is prevented from oscillating and free from the addition of unnecessary and unnatural force as expanding and contracting linearly.

Abstract: PURPOSE: To ensure highly reliable determination at impact time where an attack is made, by measuring a time difference between first and second time points, and calculating the time where a laser beam reaches a laser alarming apparatus based upon a base where an amplitude involved by a constant is proportional to a distance to the laser beam. CONSTITUTION: When a reception robe 3 is rotated in a rotation plane, and a sending robe 2 of a laser light source 1 is coincident with a sensitive robe 2, a pulsed laser beam is emitted from the laser light source 1, and light produced in a laser scattering area is detected with the reception robe 3 and a measuring device 6 sets an impact time value. More specifically, an amplitude is set utilizing the amplitude of a pulse width received for each rotation, which value is incorporated into an equality to calculate the impact time. The amplitude A raised to n-th power is proportional to a distance to the laser beam, and an equality D=K.A<n> holds. Herein, K and n are constants, D is a vertical distance to the laser beam, and A is a detected amplitude value.

Filed: 1982-06-30
Abstract: PURPOSE:To correct automatically a position input of a light pen, by measuring the time required for obtaining an input signal again by a scanning address unit, and subtracting it from a scanning address which stores this measured value. CONSTITUTION:A CRT controlling circuit 10 sets a present scanning address to a register, sets one scanning line containing a scanning address to high luminance at the time of the following scanning, and also outputs a start signal 3 to a time difference measuring counting circuit 11. When a light pen detects a high luminance scanning line and a signal 1 becomes on again, a stop signal 4 of the counter 11 becomes on. When this signal 4 is inputted, the counter 11 sets a measured value to the register, the register gate of the circuit 10 is opened by a gate open signal 5, and a subtracting circuit 12 is made to subtract a value of a delay from a value containing a delay. A light pen interrupting signal 6 is outputted to a CPU from said result, and a position on a CRT where optical and electrical delays of the light pen are corrected is obtained.
