Title: Barrel for surface treatment and method for putting object to be treated into and out of said barrel
Inventor: KIRISAWA TADASHI
IPC: C23G3/00
Filed: 1986-08-06
Abstract: PURPOSE:To enable continuous and automatic surface treatment by providing a pair of cap plates which open outward and locking-unlocking mechanism to the aperture in the peripheral cylindrical part of a rotary perforated vessel and discharging and charging the objects to be treated automatically from and into the vessel according to the rotation thereof. CONSTITUTION:This barrel for surface treatment is provided with the aperture 6A in the peripheral cylindrical part of the perforated vessel 1A and the neck edges of a pair of the cover plates 7A, 7B are respectively pivotally fitted to both edges thereof. The cap plate locking-unlocking mechanism is mounted between the cap plates 7A and 7B. The mechanism is formed of a detaining hook part 13A, detaining piece 8A and detaining hook part actuating mechanism. The barrel is rotated in the unlocking state of said unlocking mechanism while the objects to be treated are held contained in the barrel. The objects to be treated are thus discharged from the aperture 6A. The aperture 6A is put into the half open state as the aperture moves upward. The objects to be treated are charged into the barrel from the aperture in said position. The cover plates 7A, 7B are closed and locked when the barrel further rotates.

Title: Preparation of new urethane oligomer
Inventor: OKADA TOMOYUKI
IPC: C09D175/00
Filed: 1987-07-24
Abstract: PURPOSE:To prepare the title oligomer which forms a cured film by irradiation, by (meth)acryloylating both ends of the main molecular chain of a urethane oligomer having hydroxyl groups on both ends of its main molecular chain which has been synthesized from a specified dihydroxyl compd. CONSTITUTION:A dihydroxyl compd. of formula I (where R1, R2 and R4 are each alkylene; R3 is a hydrocarbon; R5 is H, CH3) (e.g., compd. of formula II) is reacted with a diisocyanate compd. (e.g., 2,4-tolylene diisocyanate) and a polyol compd. (e.g., polytetramethylene glycol) to give a urethane oligomer having hydroxyl groups on both ends of its main molecular chain. Then the oligomer is acryloylated at its both ends by reacting the oligomer with a diisocyanate compd. to introduce isocyanate groups into both ends of its main molecular chain and then reacting said groups with a compd. having a (meth) acrylic double bond and a group capable of reacting with an isocyanate group, e.g., 2-hydroxylethyl (meth)acrylate.

Title: Power amplifier circuit
Inventor: YAMAMOTO TOMOHIKO
IPC: H03K17/687
Filed: 1991-07-24
Abstract: PURPOSE:To make the size small and to reduce the cost of the power amplifier circuit by forming a circuit varying the bias state of the power amplifier circuit to form the power amplifier circuit adaptable to both digital and analog communication systems with one unit circuit. CONSTITUTION:When an H level control signal is given to a control node 8, a MOSFET 6 is turned on and a base side feeding line 2 of a transistor(Tr) 1 is grounded. Moreover, since a bias is applied to the MOSFET 7 via an inverter 9, the MOSFET 7 is turned off. Thus, the base side feeding line 2 of the Tr1 and the collector side feeding line 4 are electrically isolated and the Tr1 receives a bias state for class C amplification. On the other hand, when an L level control signal is given to a node 8, the FET 6 is switched off and then the FET 7 is turned on. Thus, the base of the Tr1 is slightly biased by a prescribed setting voltage of a diode 3 to attain class AB amplification. Thus, both the class AB and the class C amplification are attained with one unit and the power amplifier circuit is made small in size and its cost is reduced.

Title: Drum type washing machine
Inventor: YAMASHITA HIDEKAZU
IPC: D06F23/02
Filed: 1993-07-27
Abstract: PURPOSE:To automatically optimize process contents such as washing time corresponding to the quantity of cloth by detecting the quantity of cloth inside a drum by averaging the output of a displaced amount detection part at an average value processing part. CONSTITUTION:When dehydration is started, the drum is revolved, the position of a reception cylinder is changed corresponding to the balance state of cloth inside the drum, and position information is inputted to an average value processing part 2 of a control part 6 every moment as a change in the expansion/contraction displacement amount of a damper. Since the output of the average value processing part 2 is correspondent to the total weight of the reception cylinder, the weight of clothing inside the drum is detected by subtracting the weight of mechanical elements, which is already known from design, from the total weight of the reception cylinder by a cloth quantity detecting means 3. From the output of the cloth quantity detection part 3, the resonant revolving speed of the drum corresponding to this output is estimated by a resonant revolving speed estimation part 4, and the output is sent to a dehydration process control part 5. From this result, the dehydration process control part 5 controls succeeding dehydration process by using the detected resonant revolving/ speed so that any inconvenience can not be generated from a viewpoint of the safety.

Title: Automatic focusing system
Inventor: TAKEBE SEIJI
IPC: H04N5/232
Filed: 1989-07-18
Abstract: PURPOSE:To accurately detect the best focus position by calculating the variance of data regarding the brightness of a subject by focus positions and regarding the maximum value of the variance as the best focus position. CONSTITUTION:A control circuit 6 calculates data of a signal (e.g. brightness signal) regarding the brightness of the subject stored on a memory 3 at intervals of a time (e.g. 100 ms) which is preset and inputted to a memory 9 to find its variance. When the best focus position is obtained, the widest distribution range of brightness is obtained, so the position where the variance becomes maximum is the best focus position. Namely, the variance of the data regarding the brightness of an image is calculated by the focus positions and the maximum value of the variance is regarded as a proper focus position. Consequently, the proper focus position is accurately detected without being affected by local brightness, etc.

Title: Induction heating fixing device
Inventor: TSUJIMOTO TAKAHIRO
IPC: H05B6/10
Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To restrain a current quantity so as to reduce power consumption in the initial stage of temperature rise and to prevent temperature rising speed from getting low to the utmost by energizing both 1st and 2nd coils in the initial stage of the temperature rise and energizing only the 1st coil after a fixed time elapses. SOLUTION: A part of a core 5 round which the 1st coil (induction coil) 3 is wound and where a closed magnetic circuit is formed pierces the inside of a fixing roller 1. The 2nd coil (current restraining coil) 4 is wound round the core 5, and the coils 3 and 4 are connected in series by switching operation. In the initial stage of the temperature rise, that is, from starting energizing the coil so that temperature may rise from ordinary temperature till attaining the fixing temperature, AC is applied to both coils 3 and 4. Therefore, the resistance components of both of them are added and a current value applied to the coil is lowered. After the fixed time elapses, only the coil 3 is energized. Thus, the applied current is restrained in the initial stage of the temperature rise and the temperature rising speed of the fixing device is prevented from getting low.
