Title: Processing circuit for display data
Inventor: KUROKAWA MASUYOSHI
IPC: G06T1/00
Filed: 1990-02-28
Abstract: PURPOSE:To execute the fault diagnosis of a memory, etc., and the detection of a fault part by a host computer by providing a control part for generating a load signal to a register by a request from the host computer. CONSTITUTION:The circuit is provided with a control part 11 for monitoring a blanking signal and generating a load signal to a register 9 by a request from a host computer. The host computer, first of all, writes prescribed data in a specific address of an image memory, and sets the specific address to an address register 12. To other address than said address of the image memory, other code which can be discriminated from this code is set. In such a state, in a blanking period, the load signal is supplied to the register 9, and the register 9 inputs data of the specific address. When the contents of this register 9 are read out by the host computer, whether the set code is obtained or not is decided. In such a way, a fault part can be detected easily.

Abstract: PURPOSE:To obtain a high-reliability device which securely winds the tip part of a film into a spool by providing a claw member so that it is displaceable in a spool radial direction between 1st and 2nd stand-by positions. CONSTITUTION:When the film F is loaded in a camera and a rotary means (not shown in figure) rotates the spool 3 counterclockwise after a rear cover 6 is closed, the claw member 4 at a claw part projection position has its claw parts 14a engaged with perforations of the film F, whose tip is wound around the spool 3. Then the claw member 14 is pressed in toward the center of the spool with the tensile force of the film F and moves back to the 1st stand-by position. Then when the film F is rewound after photography, the film F is loosened, so the claw member 14 is displaced from the 1st stand-by position to the 2nd stand-by position and the film is never wound around the spool extremely in an oval shape; and take-up resistance due to a collision between a claw part 14a and a film guide roller 8 across the film is prevented effectively from becoming abnormal.

Title: Sensor, fullerene-system composite film, and its manufacture
Inventor: KAWASHIMA ATSUMICHI
IPC: H01L29/12
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To obtain a sensor that can be operated at a room temperature where durability is improved by forming a fullerene-system composite film in the lamination structure of a fullerene deposition film and a fullerene polymer film. SOLUTION: A fullerene polymer film for composing the sensor is in stable three-dimensional structure where CN monomers such as C60 are in covalent bond. When a substrate such as water is adsorbed on the film surface, conductivity increases even at a room temperature. For manufacturing the polymer film, for example a glass substrate 3 is fitted onto an electrode 5 in a vacuum container 1, and C60 is filled into a molybdenum boat 2 as fullerene. An argon gas is introduced into the vacuum container 1 and a high-frequency current is applied, a high-frequency plasma is generated between the electrodes 4 and 5, the boat 2 is energized and heated for vaporizing the C60 into plasma, and a C60 polymer film 22 is formed on a substrate 21.  In this case, by changing plasma output continuously or in steps, film structure is changed continuously or in steps from the fullerene polymer film to the fullerene deposition film or from the deposition film to the polymer film.

IPC: G04C21/16
Filed: 1981-04-03
Abstract: PURPOSE: To make it possible to know for sure the life of a battery by reducing electric current consumption in the alarm sound generating circuit after notifying of battery life.  
     CONSTITUTION: An output is generated from a clock circuit A at the time of alarming, and by this output an alarm current control circuit B operates and the alarm sound is issued from an alarm sound generating circuit C. When the battery voltage drops down to the set voltage, an output is generated from a battery life detection circuit D, and life indication is made by a battery life indication device E. At the same time the alarm current is reduced to a value lower than that in the ordinary time by the alarm current control circuit B. In this way the time from notifying battery life to stopping of the watch becomes longer, and the sound of the alarm changes, which makes battery life known positively.
