Title: Oscillator
Inventor: HORIUCHI YOSHIFUMI
IPC: H03L7/06
Filed: 1994-12-14
Abstract: PURPOSE: To obtain an oscillator having high frequency stability by independently controlling the frequency and phase of a voltage controlled oscillator(VCO). CONSTITUTION: A phase comparator 17 detects a phase difference between a reference pulse signal 16 with an one-sec period outputted from a GPS receiver 15 and a pulse signal with an one-sec period obtained by dividing the frequency of an output from a VCO 11 by a counter circuit 13. The variation of a phase difference in each sec is found out by a delay circuit 31 and a difference calculating circuit 32 and the average value of the variation is found out by an averaging circuit 35. Control voltage is changed so as to reduce the average value of the variation, the frequency of the pulse signal 14 is allowed to coincide with the signal 16 and the current voltage value of the control signal is stored. The voltage of the control signal is changed to match its phase. When both the phases coincide with each other, the voltage value of the control signal is returned to the stored value.  Since oscillation frequency is controlled based upon the average value of the variation in the phase difference, the long term frequency stability of the GPS signal is reflected to the stability of the oscillation frequency of the VCO 11.

Title: Label identification device
Inventor: HASHIBA SATOSHI
IPC: G06K19/06
Filed: 1988-12-07
Abstract: PURPOSE:To identify a label even when the surface state of the label is deteriorated by thermochemical treatment by equipping the device with an adsorption pattern label to write information according to the existence of a hole and an adsorption detecting means to detect whether plural adsorption ducts arranged at positions having the same rule are under an adsorbing state or not. CONSTITUTION:At detection time, an adsorption pattern label 10 is sucked by the adsorption ducts, and since no detecting holes are opened at detection positions 1 and 3, the label 10 is sucked by a vacuum hose 19 in adsorption hoses 31 and 33 connected to adsorption ducts 11 and 13, the hoses are made into a vacuum state, and adsorption sensors 41 and 43 detect 'adsorption ON.' Since the detecting holes are opened at detection positions 2 and 4, outdoor air flows in adsorption hoses 32 and 34, the hoses are never made into the vacuum state, adsorption sensors 42 and 44 detect 'adsorption OFF,' and information given to the adsorption pattern label 10 can be reproduced. Thus, even when the surface state of the lable such as the reflectivity, the contrast, and the color of the label is changed as the result of heat treatment and chemical treatment, the identification capacity of the device is never influenced by the change.

Title: Internal combustion engine
Inventor: FUJIMOTO KANEO
IPC: F01C1/16
Filed: 1988-12-07
Abstract: PURPOSE:To solve demerits of the capacity type and speed type and equip merits by rotating a rotor with the static pressure of a combustion gas supplied into each tooth groove, which is shut between the meshing position of rotor and the casing. CONSTITUTION:A starter device rotates shafts 1, 2 oppositely to each other in the direction of increasing the capacities of tooth grooves 13, 14 leading to the combustion chamber 16. At this time, the fuel from a combustion gas supply hole 20 and the compressed air from a compressed air supply meazs 35 are fed to the combustion chamber 16 and tooth grooves 13, 14 in communication therewith, and thus the fuel is combusted. This results in chain combustions of the fuel contained in the compressed air, and the capacities of the tooth grooves 13, 14 are increased by the static pressure of combustion gas generated by these chain combustions, which gives rotors 8, 9 a rotational motive. This does not require a large rate of flow of the combustion gas, accomplishes the construction light and easy-to-use, and enhances the efficiency, compared with a speed type engine. Also this is suitable for the case with large output and does not involve large vibration or noise which is likely in a capacity type engine.

As a result, the sequence control with high efficiency is carried out in response to the moving distance of the head part.
