Patent JP-H0229010-A (JP)
Title: Amplifier
Inventor: TAIWA OKANOBU
IPC: H03F3/45
Filed: 1988-07-18
Abstract: PURPOSE:To improve the characteristic of distortion factor by connecting 1st and 2nd differential amplifiers in parallel, selecting the ratio of two output currents in the 1st differential amplifier to be 1:N and selecting the ratio of two output currents in the 2nd differential amplifier to be N:1. CONSTITUTION:Differential amplifiers 1, 2 are connected in parallel, and the ratio of collector currents of transistors(TRs) Q1, Q5 and Q2, Q4 is taken opposite to each other. As a result, even if harmonic distortion of even order number takes place in the amplifiers 1, 2, the distortion is cancelled at output currents, + or -1 and harmonic wave distortion in the even order number is not almost included in the output currents + or -1. Moreover, the ratio N of the collector currents is selected and then a 3rd harmonic distortion is not almost included in the output currents, + or -1. Thus, when the N is selected to be 2+3<1/2> (N=1 for a general differential amplifier), the distortion is less by 30dB or over than that of the general amplifier and the distortion characteristic is considerably improved.

Title: Longitudinal vibration type piezoelectric vibrator
Inventor: NEGITA MUTSUMI
IPC: H03H9/17
Filed: 1983-09-27
Abstract: PURPOSE:To obtain stable performance at a frequency band between several hundreds kHz and several MHz by increasing the width of a support connection part more than the width of a main vibration part, increasing the thickness more than a thickness being 0.6 time the thickness of the main vibration part and decreasing the length of the support connection part less than two times the width of the main vibration part. CONSTITUTION:The vibrator consists of the main vibration part 15, the support connection parts 16a, 16b, supporting arms 17a, 17b and a support 18. The width W2 of the support connection parts 16a, 16b is larger than the width W1 of the main vibration part 15 and larger than 0.6 time the thickness T of the main vibration part 15. Moreover, the length L1 of the support connection parts 16a, 16b is decreased less than 2 times the W1. Through the constitution above, the longitudinal vibration type piezoelectric vibrator having less vibration energy leakage, excellent CI value and oscillated stably at a broad temperature range is obtained.

Title: Surface mounting printed wiring board and mounting method for component thereof
Inventor: UMEMOTO SHINJI
IPC: H05K3/34
Filed: 1990-07-04
Abstract: PURPOSE:To further enhance connection reliability by specifying the film thickness of a solder mask and a foot print. CONSTITUTION:When the film thickness of a solder mask 4a is reduced to be 10 to 20mum thinner than the film thickness of a foot print 2a, Solder cream 9a, which is 10 to 20mum thinner than the film thickness of a printed board 11 to print the cream solder 9a and 9b, is printed on the foot print 2a. When the film thickness of a solder mask 4b is increased to be 25 to 70mum thicker than the film thickness of the foot print 2b. melting solder 2 is apt to cut on the border of the end face of the solder mask 4b which surrounds the foot print 2b so that the melting solder may fail to adhere to the solder mask 4b. This construction makes it possible to protect non-soldered portions and its neighboring circuit portions from short circuits or the like definitely.

Title: Channel lock device
Inventor: MATSUI MITSUKO
IPC: H04N5/76
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To permit the simple selection of lock continuation/release on the spot by displaying a screen for selecting the lock continuation/release when a channel exclusive of the locked channel is selected during the channel lock. SOLUTION: A microcontroller 103 receives an input state from a user input processing device 105 and controls a channel-select circuit 101. A video signal processing circuit 104 processes video signals and outputs the signals to an image receiver. A display device 106 displays the information to a user. The microcontroller 103 instructs the screen display for selecting the lock continuation/release to the display device 106 when the channel exclusive of the locked channel is selected during the channel lock. As a result, the need for displaying a selection screen as to whether the channel change during the lock is made possible or not when the channel exclusive of the locked channel is selected during the channel lock may be averted.

Title: Device for automatically adjusting focal point of camera
Inventor: ISHIKAWA NORIO
IPC: G03B13/36
Filed: 1982-10-13
Abstract: PURPOSE:To extremely improve the focal point adjusting accuracy, by giving a large weight to the latest signal among signals outputted from a focal point detecting device, and obtaining a mean value of the plural signals. CONSTITUTION:To make focussing operation in a short time, the detecting operation of defocus signals is repeatedly performed while a photographing lens 4 is moved toward the focussing point. Therefore, a mean value of the latest defocus signal and previously detected defocus signals out of those periodically outputted from a data processing circuit is obtained and the photographing lens 4 is controlled by using the mean value. The mean value is obtained by giving a larger weight to a newer signal in time series. By controlling the photographing lens 4 to a proposed focussing point in accordance with signals from an averaging processing circuit in such a way, the focal point adjusting accuracy can be improved extremely.
