Title: Image processor
Inventor: USAMI AKIHIRO
IPC: G03G15/06
Filed: 1983-06-30
Abstract: PURPOSE:To make a titled device adaptive to a partial change in the density of an original and to shorten the time for starting image formation by controlling the value of bias for development with the density values of the original detected in plural regions. CONSTITUTION:When a copying start button is pushed, the 1st mirror 104 and the 2nd and 3rd mirrors 105 scan an original 101 at a speed ratio of 2:1. A means 107 for detecting the quantity of light samples the quantity of light at every 0.1sec and stores successively the same in an RAM via an A/D converter. The bias for development is determined according to the average value of the sampling data between A-C of the original in the stage of developing the position B of the original at the point (b) in a developing device 110. The sampling data between B-D is similarly used in the stage of starting development of the point C and therefore the bias is controlled by the average data before and behind the point to be developed. Good accuracy is thus obtd. and the device is made adaptive with a partial change in the density of the original.

Title: Method and device for raster radar measurement
Inventor: FUKUSHIMA MADOKA
IPC: G01K11/24
Filed: 1986-05-23
Abstract: PURPOSE:To accurately measure a temperature altitude distribution in an atmosphere remotely by discarding a measured value obtained below the lower limit value of a horizontal wind speed. CONSTITUTION:The wave front of a pulse acoustic wave which forms the wave front of a spherical compressional wave transmitted through an acoustic wave antenna 9N in the north direction is irradiated with a continuous wave from a north-directional radio wave transmitting antenna 6N, and the reflected radio wave is received by a lattice type radio wave receiving antenna 10. The east, west, and south directions are the same and a wind direction and wind speed computing element 12 computes the horizontal wind direction and wind speed at each altitude on the basis of the maximum received signal level value of an antenna received signal. A temperature arithmetic part 13, on the other hand, analyzes the frequency of the received signal to calculate the temperature at each altitude on the basis of a Doppler frequency which varies with the temperature. In this case, when the horizontal wind direction computed by the arithmetic part 12 decreases below the lower limit value, the arithmetic operation of the arithmetic part 13 is stopped through the arithmetic part 12 to preclude wrong arithmetic operation due to pseudo Doppler effect, so that the temperature altitude distribution in an atmosphere is measured accurately and remotely.

Title: Production of maleinized polyvinyl alcohol
Inventor: TANIGUCHI YASUO
IPC: C08F8/12
Filed: 1979-09-17
Abstract: PURPOSE: To increase the rate of copolymerization and to obtain maleinized polyvinyl alcohol having excellent solubility, by reacting vinyl acetate with maleic acid in the presence of an alkali, and thereafter saponifying the product.  
     CONSTITUTION: Vinyl acetate is reacted with maleic acid or maleic anhydride in the presence of an alkali in an amount of 0.5W2.0mol eq., based on maleic acid or maleic anhydride, in an organic solvent, and then the product is saponified. The amount of alkali used is 0.5W2.0mol eq., based on maleic acid or anhydride thereof. Use of below 0.5mol eq. does not provide improved copolymerizability and water solubility, whereas use of above 2.0mol eq. results in hydrolysis of vinyl acetate and consequent formation of formaldehyde, which unfavorably inhibits the polymerization.

Title: Ultrasonic probe
Inventor: ENJIYOUJI SUSUMU
IPC: B06B1/06
Filed: 1978-09-28
Abstract: PURPOSE:To simplify manufacture by simplifying the structure of an ultrasonic probe by relaxing the condition of the width of a vibrator by using titanic acid lead-based ceramic for the vibrator. CONSTITUTION:Since titanic acid lead-based ceramic provides the great relaxation of the condition of the width of a vibrator for the damping of unneeded lateral vibration, the width size can be elongated, so that it will be suitable for an ultrasonic probe. Vibrators 4 using this material are made to correspond to electrodes 2 at the same pitches as electrodes 2. In this constitution, each vibrator 4 can remove sufficiently unneeded vibration by one element for one electrode. The structure is therefore simple and an ultrasonic probe, even in case of use for high frequencies, can easily be manufactured.
