Title: Rectangular at-cut quartz oscillator
Inventor: SHIRATORI NORIHIKO
IPC: H03H9/19
Filed: 1983-03-23
Abstract: PURPOSE:To attain a mass production of oscillators of stable quality by providing plural tooth-shaped frequency control electrode patterns to the oscillating main electrode patterns so as not to be opposed to each other. CONSTITUTION:A rectangular AT-cut quartz oscillator 20 contains a pair of oscillating main electrode patterns 25 and 26 extending in the lengthwise direction of the oscillator 20. At the same time, plural tooth-shaped frequency control electrode patterns 27 and 28 are extended from patterns 25 and 26 at both ends and in the width direction of the oscillator 20. In this case, the patterns 27 and 28 are not opposed to each other. The frequency is controlled by trimming the frequency by a laser beam from the tip part of patterns 28 and 29 respectively. This the control of frequency is possible with no increment of CI value nor the reduction of stable quality. Thus a mass production is possible for oscillators of stable quality.

Abstract: PURPOSE:To prevent an increase in the number of pins in an integrated circuit by sharing the power source pin for writing a program to a PROM and the control pin for a standby circuit for reducing a power consumption during a non-operation. CONSTITUTION:Level comparators 3, 4 compare the signal 1 of the power source pin with the signal 2 of a VPP pin for impressing a voltage higher than a source voltage supplied for the program, and only when the comparators 3, 4 decide that the signal 2 is situated in a higher or a lower level, respectively, the voltage of the high level is outputted respectively to a writing control line 5 and a standby control line 6, thereby, only when the liens 5, 6 go to the high level, the writing circuit and the standby circuit are respectively activated. Accordingly, by impressing a writing voltage to the VPP pin, the writing of the data is carried out, and when the source voltage is impressed, the writing circuit as well as the standby circuit are not activated but remain an ordinary using state. Under the non-operation state, a low voltage is impressed, thereby, the standby circuit is activated and the low consumption of power is attained.

Abstract: PURPOSE:To eliminate the need for a focusing sensitivity correcting means for an auxiliary lens group by attaching the auxiliary lens group to a lens barrel in front of a photographic lens so that the auxiliary lens group is fixed to the image surface of the photographic lens. CONSTITUTION:When an auxiliary lens group 3 is set in front of a photographic lens 20, it is attached to a part of a fixed lens barrel 2.

Title: Vhf-uhf tuner

IPC: H03D7/16
Filed: 1980-04-14
Abstract: PURPOSE:To reduce noise and distortion by suppressing spurious disturbance, by using the difference between an input signal frequency obtained through the frequency conversion of a mixer and the frequency of a voltage-controlled oscillator as an intermediate frequency. CONSTITUTION:An input signal from terminal 40 is inputted to the 1st input terminal of the 1st mixer 45 via filter 41 and RF amplifier 43, and the output of voltage-controlled oscillatot 47 is amplified by amplifier 46 and then inputted to the 2nd input terminal of mixer 45. Then, the difference between the oscillation signal frequency of voltage-controlled oscillator 47 and the frequency of the input signal is set as the 1st intermediate frequency. In this case, the 1st intermediate frequency is set within the range of 2,520-2,700MHz, so the frequency of voltage-controlled oscillator 47 is set within the range of 2,613-3,287MHz. Consequently, spurious disturbance in the signal band of the 1st intermediate frequency is narrowed down to the secondary and tertiary higher harmonic disturbances occuring in the RF amplifier and the 1st mixer and an interchannel beat disturbance, and for this purpose, they are eliminated by the following circuits to reduce noise and distortion.

Title: Fuel supplying device of internal-combustion engine
Inventor: YAMAMOTO TADAHIRO
IPC: F02D33/00
Filed: 1984-03-15
Abstract: PURPOSE:To maintain air-fuel ratio stable when a portion of fuel becomes wall flow as well as to control highly accurate air-fuel ratio at the time of low load when intake air amount is less by controlling fuel flow rate by detecting air- fuel ratio of actual mixture air directly by temperature drop in inlet air due to evaporating heat of fuel. CONSTITUTION:When flow velocity in a throat unit 21 is large, injected fuel is rapidly evaporated and the difference in temperature corresponding to the actual air-fuel ratio between a first thermocouple 31 and a second thermocouple 32 is detected. Feedback control is made by utilizing this difference in temperature. Then air-fuel ratio accuracy at the time of low load near idling becomes extremely better. At the time of high load when flow velocity of the throat unit 21 becomes small, 100% evaporation of fuel becomes difficult and unevaporated liquid fuel becomes wall flow and collected in the form attached to a vertical wall 1c. Therefore, only evaporated fuel contributing temperature drop between the first and the second thermocouples 31, 32 flows into an engine and no error is generated in air-fuel ratio.

Abstract: PURPOSE:To prevent occurrence of an accident due to careless negligence, by attaching a valve rectangularly to a perpendicular line, and fixing a support rod for indicating opening and closing of the valve to the handle part of the valve. CONSTITUTION:An indicating support rod 1 has at one end thereof a valve handle fixing part 4 while it has a indicator panel 5 at the other end. For instance, a fluorescent paint of red is applied over one surface 6 of the indicator panel 5 while a fluorescent paint of green is applied over the other surface 6'. In use of a valve, the valve is opened when the support rod 1 is tilted to the left side. At the same time, the indicator panel 5 shows its red surface 6. On the other hand, when the support rod 1 is tilted to the right side, the valve is closed, and at the same time, the indicator panel 6 is turned and shows its green surface 6'. Thus, since opening and closing of the valve can be indicated clearly not only in the daytime but also at night, it is enabled to prevent occurrence of an accident due to careless negligence.
