Title: Vibration-proof inflatable film dam
Inventor: MURAMATSU TAKEO
IPC: E02B7/20
Filed: 1981-06-08
Abstract: PURPOSE:To prevent the occurrence of vibration due to overflowing water by making the height of an inflatable film dam to be attached to the side wall higher than the maximum water level to be attained when rising the vibration- proof flexible film dam which is used for the intake of agricultural water. CONSTITUTION:When sending air into a rubber dam 1 by operating a blower, the inflatable rubber dam 1 is expanded and erected. In case where the amount of water in a dam of an usual height Ho is usual, the level of water surface 9 on the upstream side of the rubber dam 1 is about 1.1 times of the height Ho. Accordingly, the heights of both ends 1c of the rubber dam 1 on the top of the longitudinal both ends 2b of a belt-like rubber sheet 2 are set up to 1.5 times the height Ho. The downstream side space 10 is connected to the open air through both ends 1a of the rubber dam, and air is supplied into the downstream side space of the rubber dam. Also, the flow of water along the surface of the rubber dam 1 is biased toward slantly upwards from a projection 4a. Thus, the biased water flow is separated exactly and stably by the projection 4a, and therefore, the occurrence of vibration caused by the movement of the separation point can be suppressed.

Title: Dot head cleaner
Inventor: NAGOSHI HIROYUKI
IPC: B41J2/235
Filed: 1990-03-30
Abstract: PURPOSE:To shorten time for cleaning a dot pin-type head by constituting an electronic circuit which causes electric oscillation using a commercial power supply or an electric battery as power source and activating the electronic circuit to clean the dot head and check the action.

IPC: C09B35/205
Filed: 1983-05-20
Abstract: PURPOSE:To obtain an electrophotographic sensitive body high in sensitivity, easy to manufacture, and suitable for repeated uses by forming a photosensitive layer contg. a specified disazo pigment as an effective component on a conductive substrate.

Title: Method for detecting false image signal
Inventor: AGANO TOSHITAKA
IPC: G06T5/20
Filed: 1989-04-06
Abstract: PURPOSE:To accurately detect a false image signal generated due to dust, flaws, etc., on the surface of a recording medium by finding out a specific image signal from an image signal, checking whether the specific image signal is due to some adjacent picture elements or not, and when the number of picture elements is less than a prescribed number, regarding the signal as a false image signal. CONSTITUTION:A false image signal detecting device 30 compares an extracted image signal Si (i = 1 to n) with a previously set prescribed threshold Sth and finds out a value smaller than the threshold Sth. Since a signal value dropping part (b) generated due to dust or the like on the surface of an accumulative phosphor sheet 5 is generally dropped to a level lower than a part (a) carrying calcium salt, the image signal of the part (b) can be extracted as a specific image signal by setting up the threshold Sth to a proper value. Whether the specific image signal is due to some adjacent picture elements or not is decided, and when the number of picture elements is <=10 e.g., the specific image signal is decided as a false image signal. Thus, the false image signal can be accurately detected.

Title: Voltage-controlled oscillator
Inventor: MORI SHIGEKAZU
IPC: H03B5/32
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To obtain a voltage-controlled oscillator, the oscillation frequency of which can be controlled uniformly without being influenced by the characteristic variation of a transistor and the size of which can be reduced, and then, the manufacturing process of which can be simplified. SOLUTION: An external control voltage VC is dropped by the current Ids flowing through a resistor 31 formed on a semiconductor substrate and, as a result, an internal voltage V31 is given to the drain of an NMOS 32 and the input side of an operational amplifier 33. The ON-resistances of NMOSs 32 and 22 are controlled in accordance with the external control voltage VC by the feeding-back by means of the NMOS 32 and amplifier 33 and the oscillation frequency of a voltage-controlled oscillator is controlled. The resistance of the resistor 31 varies depending upon the temperature, but the temperature of the temperature detecting voltage VT of a temperature detecting section 40 provided on the same semiconductor substrate also varies depending upon the temperature.  The temperature detecting voltage VT is given to a reference voltage generating section 50 and the section 50 generates a reference voltage Vref having the opposite temperature characteristic to that of the resistor 31 and the ON-resistances are nearly fixed. Since the resistor 31 can be formed on the semiconductor substrate, the size of the oscillator can be reduced and the manufacturing process of the oscillator can be simplified.

IPC: B41M5/42
Filed: 1989-04-10
Abstract: PURPOSE:To enhance printing grade by eliminating scumming in a double density thermal transfer recording system by providing an ink layer transferred by heat and a heat-meltable fine particle layer on a support in this order. CONSTITUTION:A thermal transfer material 1 has an ink layer containing a colorant transferred by heat and a heat-meltable fine particle layer 4 containing no colorant on a support 2 in this order. In a double density thermal transfer recording method, not only the heat applied part but also heat non-applied part of the thermal transfer material generate the staining of a non-recording part (scumming) because an ink surface is rubbed with a recording medium. As a measure to effectively prevent this phenomenon, the heat-meltable fine particle layer 4 is provided. In the double density thermal transfer recording method, the moving distance of the thermal transfer material 1 to a recording head 6 is made shorter than the moving distance of a recording medium 5 to the recording head 6 within the same time. By this method, recording is performed.

Title: Patterning of photosensitive polyimide
Inventor: TAKAHASHI KEIZO
IPC: H01L21/30
Filed: 1988-04-12
Abstract: PURPOSE:To prevent film decrease of the exposed part and suppress the variations in thickness of polyimide film, by applying a negative resist on a photosensitive polyimide, performing simultaneous exposure of the negative resist, developing and rinsing the exposed negative resist, and developing and rinsing the photosensitive polyimide. CONSTITUTION:Photosensitive polyimide 2 applied on the surface of a semiconductor substrate 1 is prebaked and a negative resist 3 applied on the foregoing polyimide 2 is prebaked. A mask 4 is put on the top of the prebaked negative resist by use of marks. The negative resist located below the mask and photosensitive polyimide 2 are exposed simultaneously through the mask and then, the exposed negative resist is developed and non-exposed parts are rinsed. After that, exposed photosensitive polyimide is developed and non-exposed parts are rinsed. Then, a photosensitive polyimide insulating film having a prescribed pattern is obtained by curing the exposed parts. The negative resist which is cured by exposure shows a resistance to the developer of photosensitive polyimide. As the exposed parts of photosensitive polyimide are protected by the hardened negative resist, no development proceeds and the decrease of film is prevented and this approach minimizes the variations of the film thickness inside the surface of the film as well.
