Title: Lens barrel of zoom lens
Inventor: TANAKA KAORU
IPC: G02B7/08
Filed: 1989-01-30
Abstract: PURPOSE:To attain zoom driving with a small driving space by forming a driven gear in a nearly spiral area along a track on the peripheral surface of the moving cylinder of a driving gear. CONSTITUTION:The moving cylinder 7 is positioned in a fixed cylinder and allowed to rotate about the fixed cylinder and move linearly in the direction of the optical axis, and the driver gear 7a which engages the driving gear mounted on a zoom driving motor is formed on the outer peripheral surface of the moving cylinder. When the driving gear rotates, the driven gear is rotated through a cam mechanism about the fixed cylinder and also put in linear motion along the optical axis. The driving gear moves drawing a spiral track relatively to the moving cylinder and the driven gear 7a is formed along the track, so the spiral driven gear 7a passes the driving gear actually at all times. Consequently, the limited space is utilized effectively to reduce the size of the lens barrel on the whole.

Title: Digital camera
Inventor: ONO NATSUYUKI
IPC: H04N9/07
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To drastically reduce the deterioration of frequency components needed for character recognition and to enhance character recognition ratio. SOLUTION: At character recognition image-pickup of a digital camera, a camera control part 108 instructs an image binarization part 105 to perform binarization processing of the image. Then, when the image binarization part 105 refers to contents of a frame memory 102, interprets the data of each pixel as luminance data as they are and has a luminance more than a certain threshold, other wise it interprets it as being white or black. Thus, by binarizing the image and writing it in an image storage part 106, it is determined whether or not it is an image-pickup for the character recognition pixel, a binary pixel that is not much distorted is taken out without performing pixel mixing processing at image-pickup of the character recognition pixel and the character recognition ratio is improved.

Title: Gain control circuit
Inventor: OGAWA SHIGEO
IPC: H03G1/00
Filed: 1981-02-17
Abstract: PURPOSE:To increase the extent of gain control by a PIN diode at a high frequency by connecting the PIN diode and a capacitor in series between the ground and the collector of a common emitter transistor constituting an amplifier. CONSTITUTION:A PIN diode 31 and a DC stopping capacitor 32 are connected in series between the ground and a connection point between the collector of a transistor TR2 and an inductance element 13 for impedance matching. The inductance of this element 13 is much greater than the lead inductance of the diode 31. Therefore, the ratio of impedance when an output side is viewed from the collector of the TR2 and that when a gain control circuit including the diode 31 is viewed is nearly constant against the frequency when an enough current is flowed to the diode 31 to reduce highfrequency resistance. Consequently, enough AGC is exercised even in the high frequency range.

Abstract: PURPOSE:To enhance a printing capacity by a method wherein a printer is provided with an arithmetic processing function capable of calculating an acceleration/ deceleration time and a printing time for every indicated printing speed for a printing line, and an optimum printing speed corresponding to characters to be printed is judged according to the result of the arithmetic processing. CONSTITUTION:Where an arbitrary printing line is 101 and a printing speed of a printing carriage for this line is assigned by 104, in a printing time operation and optimum printing speed control part 207 an accelerating time from a reference number 0 to 107, a printing time from 107 to 108, a decelerating time from 108 to 111, and a total time T1 of these times are calculated. Similarly, when a printer is controlled with a printing speed 105 lower than the printing speed 104, an accelerating time from 0 to 106, a printing time from 106 to 109, a decelerating time from 109 to 110, and a total time T2 are calculated. When the time T2 is too short, a master CPU data edit and printer system control part 204 controls the travel speed of a printing carriage so that the printing carriage can be controlled to be a value as shown by a reference number 103.

Title: Pasteurizer dealing with no-load
Inventor: KAWAHATA YOSHIFUMI
IPC: B65B55/02
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To maintain a stable temperature-distribution pattern even if an interruption of carrying work occurs during an operation, by providing a closed loop, via an adsorption refrigerator, between the upstream storing tank and furthest downstream storing tank in a slow cooling area. SOLUTION: When a no-load detection element 12c detects an interruption of carrying work, a solenoid valve 17 is actuated, and stored water in a slow- cooling heat-exchange chamber 13a is passed through a heater 15 to be heated to a proper temperature, then, guided into the heat-source side A of an adsorption refrigerator 14, and further guided to the cooling side B after subjected to heat radiation in a cooling tower 16, so that cold water having a specific temperature is obtained. Subsequently, the cold water is guided into a slow- cooling heat-exchange chamber 13 c, overflows in the G direction, and passes to a heat exchange chamber 13b, which is upstream.  The cold water after passing to it is fed under pressure, via a reflux path 21, to the jetting part of a preheating heat-exchange chamber 11a which is the furthest upstream, so that a reflux path by overflow in the H direction is formed. Thus, an abnormal increase in the temperature of the stored water caused by the interruption of the carrying work is adjusted to a normal temperature-distribution.

IPC: B21D13/02
Filed: 1979-02-28
Abstract: PURPOSE: To inexpensively produce the corrugated ribs of high quality with good productivity by using a material feeder with antireturn mechanism and forming the specified amount of spacing between the bed and upper die of the press machine at the molding process.  
     CONSTITUTION: A strip-form material 21b is guided between upper and lower dies 31, 32 on the bed 34 of the press machine through an uncoiler, leveler, loop area and material feeder with antireversing rollers. Thence, the  press machine lets its upper slide 30 descend and has the material 21b lightly sandwiched between the upper die 31 and bed 34. In this state, the feed mechanism is opened. Next, the lower die 32 is moved upward and the upper die 31 is lifted to form a spacing (g). However, the material 21b is prevented from going back by the antireversing rollers. When the lower die 32 is further moved upward, the material 21b is withdrawn smoothly by passing through the feed mechanism. The lower die 32 is moved upward by the specified amount and is then stopped, after which the upper die 31 is again lowered to strongly hold the material 21b with the bed 34. The upper die 32 is further moved upward by the specified amount (f), whereby stretching is done.

Abstract: PURPOSE:To enhance analytical accuracy by improving the separation of oil and the gas in the oil while performing stable gas analysis, by arranging a solenoid valve to a part above a gas extraction cylinder and arranging a selective check valve above said solenoid valve. CONSTITUTION:A point different from a conventional one resides in that the route of a solenoid valve 11 and a check valve 12 is connected to the piping to an analytical apparatus system extending upwardly from a gas extraction cylinder 1 and a selective check valve 14a is used in place of an oil detector 14 to be connected to said solenoid valve 15. In the selective check valve 14a, oil rising from below flows into a hollow body 27 and succeedingly rises while a float 29 is floated but, when the float 29 reaches a place where is the upper part of the hollow body 27 and has a narrow diameter, it is not raised thereabove and, therefore, the advance of oil is also inhibited. The float 29 is placed on a scale tray 28 in an oil absent state but, because the size of the float 29 is properly made smaller than that of the scale tray 28, extracted gas can pass the lateral side of the float 29.
