Title: Screen saver and display data management system for the same, simple image data base, and display screen secrecy holding system
Inventor: MATSUDA KENTARO
IPC: G09G5/00
Filed: 1994-04-22
Abstract: PURPOSE:To prevent partial or entire sticking due to an afterimage of a picture on a CRT display by displaying a main still picture on the CRT display. CONSTITUTION:A main memory resident program measures the stagnation time of normal transation, which is saved on a main memory and erased from a screen; and a necessary still picture window and a message window which is moved by clipping in a necessary direction at the same time are displayed, and music or a voice is outputted. The display is switched to a next necessary still picture window after the necessary display time of one still picture window lapses and as the normal transaction is restarted, the necessary still picture window and a subordinate window for movement messages are erased; and the output of the music or speech is stopped and the normal transaction screen which is saved is reloaded.

Title: Photoacoustic analysis method
Inventor: WATANABE ATSUO
IPC: G01N21/00
Filed: 1978-10-03
Abstract: PURPOSE:To carry out the analysis for the sample by supplying the output of the thermal flowmeter type detection element to the synchroscope and thus securing the observation for the waveform and its change of the output between the pulse beams which are irradiated intermittently toward the sample. CONSTITUTION:The sample is analyzed by making use of the photoacoustic effect in the following method. Sample room 15 and reference room 16 which are filled with the gas are linked to each other via gas path 17, and at the same time thermal flowmeter type detection element 20 is incorporated onto path 17. Then the pulse beam featuring a fixed frequency is irradiated through light transmission window 18 to sample 14 in room 15 to cause the flow of the gas within path 17. The gas flow is detected by detection element 20, and this output is supplied to the synchroscope. Thus the waveform and its change of the output between the pulse beams are observed through the synchroscope.

Title: Semiconductor laser driving apparatus
Inventor: YOSHIKAWA SEIJI
IPC: H01S5/042
Filed: 1985-06-05
Abstract: PURPOSE:To protect the apparatus from breakdown and deterioration, by applying a driving voltage only when normal voltages are supplied to a driving circuit, and stopping the application of a voltage to a semiconductor laser when inadequate voltages are supplied to the driving circuit. CONSTITUTION:Voltages 82, which are applied to a driving unit 1, are inputted to a supplied-voltage monitoring means 12. When all the supplied voltages are normal, a monitor output signal 131 at an H-level is inputted to a transistor (Tr) 132. A laser driving command signal 83 is inputted to a Tr 133 as a command signal at an H-level. Then the Trs 132 and 133 are turned ON and a switch 135 is changed. Thus the short circuit of a semiconductor laser 7 is released. When the supplied voltages 82 are inadequate, the supplied-voltage monitoring means 12 outputs an L-level. Therefore, the Tr 132 is in the OFF state, and the current does not flow through a relay 134. Therefore, the switch 135 keeps the shorted state of the semiconductor laser 7.

When the degree of saponification of the polyvinyl alcohol is higher than 85mol%, tendency toward deterioration by heat upon forming is increased and the appearance of the formed article is impaired by coloration. In addition, when the amount of the polyvinyl alcohol is less than 2wt% of the composition, dying property, antistatic property and water desorption property of the product becomes insufficient, and on the other hand, when the amount is in excess of 50wt% the stretchability is reduced.
