Title: Liquid crystal printer
Inventor: MIYAZAKI NOBUO
IPC: G03G15/04
Filed: 1991-04-09
Abstract: PURPOSE:To make a false contour of a recording image on a photosensitive material inconspicuous and to increase the number of gradations of the recording image when a liquid crystal panel with the relatively small number of gradations which can be displayed is used. CONSTITUTION:An offset generating means 10 applies a wedgelike offset voltage which increases in level wedgewise gradually, a periodic offset voltage which increases and decreases in level periodically and gradually, or a step wedge type offset voltage which increases in level stepwise and wedgewise for an analog video signal outputted by a D/A converting circuit 8. The highest level of the offset voltage is set not exceeding the level of the minimum threshold value ('001') of a 3-bit A/D converting circuit 12. The analog video signal applied with the offset voltage is converted by the A/D converting circuit 12 into a 3-bit digital signal corresponding to the display characteristics (8 gradations) of an LCD panel 16. An LCD control circuit 14 drives respective picture elements of the LCD panel 16 corresponding to the signal. The offset voltage is applied to shift and make the false contour inconspicuous and the number of gradations of the recording image also increases.

Title: Combustion appliance
Inventor: TOMINAGA NAOTO
IPC: F23N3/08
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To precisely make a self-check of the clogging and deterioration of ventilation of a combustion device. SOLUTION: An air quantity value temperature correcting part 22 corrects the temperature of a target air quantity value corresponding to the reference test rotating speed of a combustion fan 3. The data of exhaust variation determined by the installing state of an appliance is stored in a variation data storing part 23. A threshold setting part 25 sets a threshold value as a reference for deciding the clogging and deterioration of ventilation relative to the reference test rotating speed depending on the exhaust variation. A ventilation clogging and deterioration deciding part 26 rotates the combustion fan 3 so as to obtain the temperature corrected target air quantity. At that time, the rotating speed of the combustion fan 3 is detected by a fan rotation detecting sensor 28.  The deciding part 26 decides a state of clogging and deterioration of the ventilation and outputs a ventilation deterioration detecting signal when the detected value of the rotation of the fan exceeds the threshold value set relative to the reference test rotating speed toward the clogging and deterioration of ventilation.

Inventor: TOKUNAGA MASAHIDE
IPC: G02B1/10
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To prevent the peeling of a translucent reflecting film from the substrate as well as to suppress the cracking of the film due to a thermal shock and to prevent the deterioration of the function by making the coefft. of linear expansion of each of the film and a hard coating film lower than that of the substrate. SOLUTION: This optical half mirror 1 has a transparent substrate 2 made of a synthetic resin, a translucent reflecting film 3 formed on the substrate 2 and a hard coating film 4 coating the film 3. The coefft. of linear expansion of each of the films 3, 4 is lower than that of the substrate 2. The thermal expansion and shrinkage of the substrate 2 are suppressed by the coating film 4 and the cracking of the reflecting film 3 due to sudden thermal deformation of the substrate 2 can be prevented. Since the reflecting film 3 is coated with the coating film 4, the peeling of the film 3 from the substrate 2 is prevented even if the film 3 cracks and the function can be maintained.

Abstract: PROBLEM TO BE SOLVED: To eliminate a cycle master function by performing data transfer with synchronous transfer when a node that becomes a cycle master exists on a common serial bus and performing data transfer with asynchronous transfer when it does not exist. SOLUTION: Each node consists of a workstation 1 that is a center, a video camera 2, a laser beam printer 3, a scanner and an inject printer 5, and a cable 6 of a serial bus connects nodes. A switching means that decides whether information transfer performed among plural devices is carried out with synchronous transfer or asynchronous transfer is provided, and a controlling means operates the switching means according to notification. That is, when a cycle master exists, synchronous transfer is selected and data transfer is executed. When a cycle master does not exist, asynchronous transfer is selected and data transfer through asynchronous transfer is performed. This enables data transfer even if devices which do not have a cycle master function are connected to each other.
