Title: Ink diluting device
Inventor: SAKAI ATSUSHI
IPC: B41J2/17
Filed: 1980-12-17
Abstract: PURPOSE:To perform a stable typing by producing a dilute solution from ink by utilizing a reverse osmotic film and supplying the dilute solution to an ink supplying system, thereby always maintaining the viscosity of the ink constant. CONSTITUTION:Ink is supplied from a cartridge 13 into an ink supplying system 10, and is injected from a nozzle. Unnecessary ink particles 11 are recovered via a gutter, and are returned to the system 10. At this time the volatile component of the ink particles volatilizes, thereby gradually increasing the viscosity of the ink. A viscosity sensor 14 detects it and produces a signal to a drive circuit 20. Since a solenoid valve 18 is opened, a pump 15 feeds the ink under pressure from the cartridge 13 through an accumulator 16 into a reverse osmotic cell 17. The fed ink is converted to dilute solution through the osmotic film of the cell 17 by a reverse osmotic phenomenon. The dilute solution is supplied via a solenoid valve 19 to the system 10, allowing the ink to be diluted. When a viscosity increase signal from the sensor 14 is not produced, the pump 15, and the valves 18, 19 are stopped to complete the dilution of the ink.

Title: Igniter for internal-combustion engine
Inventor: YAMAMOTO NOBORU
IPC: F02P3/04
Filed: 1982-10-13
Abstract: PURPOSE:To inform an operator of abnormality when any of a large number of power transistors is damaged through short-circuiting, by providing an abnormality detecting circuit detecting that a primary current of an ignition coil has been turned ON for more than a predetermined period of time. CONSTITUTION:A constant-current time pulse is applied to disorder circuit 14, during which a transistor 145 is turned OFF. Although a condenser 147 is charged through resistance, a transistor 146 does not turn ON at the time of normal operation as its time constant is made large. When a power transistor is damaged due to short-circuiting, the condenser 147 starts charging, the transistor 146 is turned ON when the condenser 147 is charged up to a regulation level, it is designed that an output D of a closed-angle circuit 1 is not applied to drive circuits 2 and 3 and any of the power transistors 5 not damaged are turned OFF for suspension of an engine. With this construction, it is possible to inform an operator of disorder.

Title: Device and method for reproducing multi-scene recording medium
Inventor: HIRAYAMA KOICHI
IPC: G11B27/00
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To record/reproduce a multi-scene by reading information on a disk, demodulating an output signal from a pickup means, storing multi-scene constitution information, reproducing second, third program information and outputting a decode output as a multiscreen video signal. SOLUTION: When the disk recorded with the multi-scene is reproduced, the data on the disk are read, and a sub-code of a data unit is read. A code showing the presence of the multi-scene is recorded on the sub-code, and when the code is detected, a reproducing device decides the presence of the setting of a frame division display mode. If there is no enlarge mode instruction, the reproducing device recognizes a program measure of a linked scene, and division displays the screen of the linked program measure. When the enlarge mode instruction is performed, the device reads the selective information of the screen to be enlarged, and normally reproduces the specified program measure.
