Title: Color temperature compensation circuit
Inventor: HAMADA YOSHIHIRO
IPC: H04N9/73
Filed: 1980-12-26
Abstract: PURPOSE:To easily obtain an integrated circuit, by executing a control of a color temperature compensation circuit against a variation of a color temperature of a copying body, by means of a digital control. CONSTITUTION:The first, second and third color optical signals are inputted from terminals 21, 22 and 23. When an electric power source 60 is connected, a clock signal from a clock terminal 50 is inputted to an up-down counter 54. When a signal from the terminal 22 among the color optical signals is larger,  and output of a differential amplifier 24 becomes a high level, and the up-down counter 54 is counted up by an increment portion of the signal. A counted-up digital signal controls an analog switching circuit 56 through a buffer amplifier 55, and decreases the degree of amplification of a color signal amplifier 4. In this way, the color temperature compensation against a color temperature of a copying body is digitally controlled completely, therefore, this compensation circuit is integrated easily.

Abstract: PURPOSE:To convert with a good S/N ratio a nonstandard frequency to a standard frequency which can be inputted to an error expanding device, by using a sampling system phase control loop. CONSTITUTION:A frequency fx to be measured is inputted to a sampling gate 3. On the other hand, to this gate 3, a sampling pulse which has divided an output of a 5MHz voltage control crystal oscillator 1 by a 1/n frequency divider 2 is inputted in advance, and the frequency fx is sampled by this pulse. This sampling output is held by a holding capacitor 4 and becomes a stepwise low frequency signal. It is amplified by a DC amplifier 5, and after that, is fed back to the oscillator 1 through an LPF6. In this way, since a phase control loop consisting of the gate 3 and the oscillator 1 is constituted, the frequency of the oscillator is controlled by an output of the LPF6. An output of a phase synchronizing oscillator is fetched through a buffer amplifier 7 from the oscillator 1. In this way, 5MHz synchronizing with the frequency fx is obtained.

Title: Energy confinement type vibrating device and vibration energy confining device
Inventor: KAIDA HIROAKI
IPC: H02K5/24
Filed: 1992-07-14
Abstract: PURPOSE:To prevent the vibration of a vibration source from leaking out by providing a vibration transmission part which receives the vibration from a vibration source and a resonance part which resonates with the vibration from the vibration transmission part. CONSTITUTION:A support rod 4 is stood on the top surface of a vibration testing machine 3 and a steel rod 5 which vibrates in inflection mode is fixed at an intermediate height position of the support rod 4. When the vibration testing machine 3 is vibrated up and down at the same frequency as the resonance frequency of the steel rod 5, the quantity of displacement of the upper end 4a of the support rod 4 is sufficiently reduced as compared with the quantity of displacement when the support rod 4 is stood on the vibration testing machine 3 without providing the steel rod 5. Namely, the steel rod 5 as the resonance part is coupled with the vibration testing machine 3 as the vibration source through the support rod 4 as the vibration transmission part, so the vibration which is propagated by the resonance of the steel rod 5 is canceled. The vibration energy of the vibration source can, therefore, be confined to the device.

Title: Diversity receiving equipment
Inventor: IMAOKA JIRO
IPC: H04L1/06
Filed: 1986-08-09
Abstract: PURPOSE:To prevent the read of an erroneous data by latching a control signal to a selection circuit by a delay output of a demodulated clock signal and making a read timing of a data different from a switching timing of the selection circuit. CONSTITUTION:After a signal received by each antenna is frequency-converted by a 1st and 2nd mixer circuits, the result is fed to level detection circuits 10, 10'. A level comparator circuit 11 compares the level of both reception signals and a selection circuit 14 selects s detector 13 or 13, having a larger level. A clock recovery circuit 16 recovers a clock signal from a demodulated data signal and supplies it to a latch circuit 18 via a delay circuit 17. The latch circuit 18 latches the output of the comparator circuit 11 in response to the output of the delay circuit 17. Thus, even if a data change and a change in the reception level take place simultaneously, since the output of the detection circuits 13, 13' is switched by a time delayed by a prescribed time, the read of erroneous data is prevented.

Abstract: PROBLEM TO BE SOLVED: To simplify structure, to facilitate working and to lighten a built-up box type member by a method wherein a plurality of steel plates are welded successively and formed in a box shape and the plate thickness of the non- welding section of at least one steel plate of the mutually welded steel plates is made thinner than that of a welding section in at least one steel plate. SOLUTION: Sections among each both end section of an upper plate 1U, a lower plate 1D, a left side plate 2L and a right side plate 2R consisting of a steel plate are welded, and formed in a box shape. Non-welding sections at central sections are indented and plate thickness t01 is formed in the upper and lower plates 1U, 1D at that time, and plate thickness t01 is made thinner than that t1 of welding sections at both end sections. Consequently, the upper and lower plates 1U, 1D are composed of shape steel beforehand molded so that plate thickness t01 of the central sections is made thinner than that t1 of both end sections by a roll, etc. As a result, stress distribution in a steel material constituting the built-up box type member 13 is maximized in the welding sections and is lowered towards the central sections.  Accordingly, the strength of the whole built-up box type member is not decreased, and structure can be simplified and lightened.
