Title: Method for improving quality of citrus food
Inventor: MIYAWAKI MASARU
IPC: A23L19/00
Filed: 1979-09-24
Abstract: PURPOSE: To prevent the clouding and eliminate the bitterness, by adding cyclodextrin within a specific amount based on the weight of a natural (unprocessed) citrus fruit to be used in preparing a citrus food to the citrus fruit.  
     CONSTITUTION: Cyclodextrin in an amount of 0.005W1.0wt% based on the weight of a raw fruit, e.g. a Citrus unshu, natsu mikan (summer orange) or shaddock, and a processed food made therefrom, e.g. a food preserved in sugar, canned goods, food preserved in a syrup, marmalade or a drink, e.g. juice, is added to the raw fruit and processed food. Thus, the clouding due to the deposition of hesperidin contained in the citrus fruit and bitterness of naringin are eliminated. If the taste of a food having the butterness remaining a little is good for the taste, the amount of the cyclodextrin is adjusted. According to the method, the use of hesperidinase or naringinase and washing with water for a long time are not required. The amount of the cyclodextrin depends on the type and gathering time of the citrus fruit and type of the processed food.

Title: Image pickup device
Inventor: TAKAYAMA TSUTOMU
IPC: H04N5/3728
Filed: 1991-04-26
Abstract: PURPOSE:To perfectly prevent the occurrence of a smear by inhibiting the transferring operation of a vertical shift register from the point of time immediately before a shutter means is turned into an open state to the point of time immediately after it is turned into a closed state. CONSTITUTION:A vertical transfer pulse is outputted again at time t7 immediately after a read-out pulse outputted after a mechanical shutter 2 is closed. Electric charge photoelectric-converted for a period from time t3 to time t5 is accumulated in a photodiode 11, but this accumulated charge is transferred to the vertical shift register 12 by the read-out pulse at time t6. Signal charge transferred to the vertical shift register 12 in this way is transferred to a horizontal shift register 13 by every one horizontal line at time t7 by the vertical transfer pulse. Besides, the signal charge of the horizontal shift register 13 is outputted from an output amplifier 14 by a horizontal transfer pulse. In this case, the occurrence of the smear is prevented by inhibiting the output of the vertical transfer pulse for the period including the period from time t1 to time t5 and immediately after the read-out pulse is outputted.

Title: Method for pwm driving brushless motor
Inventor: GALBIATI EZIO
IPC: H02P6/14
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To reduce switching loss by firmly keeping one of motor windings in low or high saturation periodically for a prescribed duration, applying the voltage of a second line to the other phase winding which is different from a first periodical voltage line, and matching the voltage of respective windings with the first periodical voltage line. SOLUTION: Samples of a voltage value profile are stored in a MEMOR, and a register Kval coefficients of three bytes to be read respectively are reduced in a MUL (numerical value multiplier). The three samples converted into a MUL are subjected to PWM conversion by a BYTE TO PWM, and the output PWM signals of the three samples are inputted into the three half bridge stages constituted of outputs BJT or MOS for providing required power gain. When one of the three values inputted into a converter in a switching phase becomes zero, the respective half bridges become low-saturated in a duty cycle, where a corresponding PWM output signal is 0%. When one of the three values becomes equals to a positive peak value, the respective half bridges become high-saturated in a duty cycle, where a corresponding PWM output signal is 100%.  A BEMF DET detects a rotor, and A/C phases are switched for synchronization.

When a solder material 12 has been melted, the photodetectors 13A, 13B are vibrated slowly inside a bonding face. The stem 15, the photodetectors 13A, 13B and the solder material 12 are matched well. After the photodetectors 13A, 13B have been vibrated for several seconds, the position of the photodetectors 13A, 13B is adjusted. Thereby, a bonding strength is enhanced, and an irregularity between the photodetectors 13A, 13B can be reduced.

Abstract: PURPOSE:To prevent the generation of blob- and icicle-shaped solder flashes to the lower part of a lead frame in the case of immersing the lead frame into a solder tank and subjecting the same to solder plating by pulling up the lead frame in an inclined posture from the solder tank. CONSTITUTION:Both ends of the lead frame 5 are clamped by clamps 4 and the lead frame is immersed into a solder bath 6 at the equal descending speed of cylinders 2a, 2b in the stage of subjecting the lead frame to solder plating. The ascending speed of the cylinder 2a is thereafter so controlled as to be made slightly higher than the ascending speed of the cylinder 2b so that said cylinder is slowly raised. The lead frame 5 successively ascends in the diagonal state toward the upper right side and the solder trying to remain in the lower part of the frame 5 flows toward the lower left along the bottom surface of the frame 5 and is recovered into the solder bath 6. The solder plating having a uniform thickness is thereby formed over the entire part of the lead frame at the point of the time when the pull up is completed.
