Title: Oscillation circuit
Inventor: ONO SHIGEYUKI
IPC: H03B5/32
Filed: 1988-04-28
Abstract: PURPOSE:To attenuate undesired N-order harmonics sufficiently from the oscillated wave by inserting an inductor in series with a collector-emitter capacitance of a Colpitz oscillator transistor(TR) or its emitter-base capacitance. CONSTITUTION:An oscillator X1 is connected between the base-collector of an oscillation TR Q1. Then the Colpitz oscillation circuit is formed by the base-emitter capacitor C2 of the TR Q1 and the collector-emitter capacitor C1. Moreover, an inductor L1 is inserted in series with the collector-emitter capacitance C1 of the TR Q1. The series resonance frequency f0 is set to the N-order harmonic by the inductor L1. The series resonance frequency f0 is selected to be f0=1/2pi(L1.C1)<1/2>. The undesired N-order harmonic component is attenuated by the oscillation source with simple circuit constitution and low cost and an excellent disturbance elimination characteristic is obtained.

Filed: 1987-04-28
Abstract: PURPOSE:To flatten the apex part of a high frequency pulse signal, by providing a pulse generator which generates a pulse voltage higher than the output voltage of a bias circuit network before a high frequency pulse input signal is inputted to a high frequency FET, and an adder. CONSTITUTION:A gate bias signal applied on an input terminal 1 is added on the bias circuit network and the pulse generator 3. The generator 3 generates the pulse voltage of a time to from the input of the gate bias signal to the addition of the high frequency pulse input signal on an input terminal 6, and adds it on the gate terminal 5 of the high frequency FET7. In such a case, the gate biasing voltage of the FET7 is set so as to maximize a drain current during the time to, and according to the steep rise of a temperature in the inside of the FET7 as the lapse of time, gain fluctuation is reduced steeply. Also, a circuit 2 generates the optimum gate biasing voltage to amplify the high frequency pulse signal by an input signal, and adds it on the gate of the FET7 with the high frequency pulse signal via the adder 4. In such a way, it is possible to flatten the apex part of the high frequency pulse signal.

Title: Oil tank device
Inventor: MATSUDA AKIO
IPC: F23K5/14
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To prevent fingers from being strained even when a work to mount and demount a tank cap to which kerosene is adhered is performed with bear hands. SOLUTION: A vertical guide cylinder 21, especially a flange forming part 22 at the tip part thereof, is formed in the very limit low enough to prevent its immersion in oil in an oil receiving tray. This constitution prevents the occurrence of constant adhesion of fuel at a normal time even when adhesion of slight fuel dripping from a discharge port 12 to the flange 22 at the tip of the vertical guide cylinder 21 is sometimes not avoided when a cartridge tank body 5 is lifted from the oil receiving tray and brought into an upside down state. Thereby, a knob handle 20 is always kept clean. This constitution simply removes a fill opening cap 9 from a fill opening 6 of the cartridge tank body 5 without soiling fingers.

Title: Peripheral pressure inspection device for cylindrical body
Inventor: TAKEMOTO SANEO
IPC: G01N3/12
Filed: 1985-05-18
Abstract: PURPOSE:To perform accurate pressure inspection by forming a pessure chamber around an object to be examined and applying a uniform pressure to the outside periphery of the object to be examined through an expansible cover member. CONSTITUTION:A pressure chamber 16 surrounded with a cylindrical body 1, a cover body fixing plate 3, a paper tube outside ring 9, and a sheet body 12 around a paper tube (a) is formed in a peripheral pressure inspection device, and a fluid is supplied from a supply entrace 17. The sheet body 12 around the paper tube (a) prevents the fluid from contacting directly with the outside peripheral surface of the paper tube (a) to protect the paper tube (a) which is degenerated by contacting with the fluid. Even if the paper tube (a) is deformed as shown by a broken line a', the sheet body 12 is deformed while being closely into contact with the outside peripheral surface of the paper tube (a) because the sheet body 12 is expansible. As the result, an external pressure acts upon the outside peripheral surface of the paper tube (a) without being affected by the sheet body 12 even after deformation of the paper tube (a) is started, and correct measurement is possible therefore.
