Abstract: PURPOSE:To more stably control the temp. of a printing head in a thermal ink jet recording apparatus. CONSTITUTION:A printing head 1 is bonded to one surface of a conductive substrate 2 having high heat conductivity and a ceramic heater 3a is bonded to the other surface almost exactly opposed to the printing head 1 of the substrate 2. A current is allowed to flow to the ceramic heater 3a in the thickness direction thereof from electrodes 3b, 3c to heat the printing head. Heating temp. is controlled by the output of the thermistor 4 arranged in the vicinity of the printing head. The temp. dependence of the ceramic heater has characteristics such that a resistance value becomes low with a temp. rise within a use temp. range.

Title: Method and apparatus for sterilizing object to be sterilized
Inventor: MASUDA SENICHI
IPC: A61L2/20
Filed: 1988-02-09
Abstract: PURPOSE:To sterilize a wetted hand piece put in a sterilizing chamber for a short time by circulating ozonized oxygen gas between the sterilizing chamber, a through hole in the hand piece and an ozonizer while heating said gas. CONSTITUTION:Ozonized oxygen gas for sterilization is circulated through a heater 8 between a sterilizing chamber 1, through hole 21b and ozonizer 7 while the ozone concentration of ozonized oxygen gas in the sterilizing chamber 1 is heightened. Said gas is further adapted to contact the surface of moisture film deposited on the outer surface of a hand piece 21 and the inner surface of the through hole to substantially heighten the ozone concentration of ozone water layer on the surface layer and the sterilizing ability. While bacili 24 in the water film is gradually exposed as the water film is evaporated, the ozone water layer then necessarily directly contact the bacili 24 on the way of exposure. The wetted bacili is swelled by the temperature of ozone gas so that under such condition high concentration ozone chases very efficiently the bacillus film to intrude into the bacili and sterilize completely them.

Title: Charger and charging system
Inventor: MASUDA HISATOSHI
IPC: H01M10/46
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To easily and surely detect on the charger side whether a battery is connected by finding out the connecting condition of the battery based on the voltage appearing at a charging terminal and the current between the charging terminal and a power circuit during the cyclic on/off operation of a switch connected between the charging terminal and the power circuit. SOLUTION: When the power is turned on, a switch 3 is turned on and off in a constant cycle by a charge controlling circuit 9. During that period, the voltage Vout across a voltage detecting resistor 7 connected to a charging terminal 2 is detected by a voltage detecting circuit 8 and the current Iout in a charging current detecting resistor 5 is detected by a charging current detecting circuit 6. When a battery 10 is not connected, the voltage Vout across the voltage detecting resistor 7 becomes the same value as the output voltage of a power circuit 1 when the switch 3 is turned on and becomes a value equal to the divided output voltage of the power circuit 1 divided by a resistor 4 and the voltage detecting resistor 7 when the switch 3 is turned off. Meanwhile, the current in the charging current detecting resistor 5 is nearly 0mA.  By this method, it can be detected whether the battery 10 is connected or not.

Abstract: PURPOSE:To previously prevent elements from being damaged on short-circuiting the output end, by coupling the DC bias power source of an inverter with the output end optically using a photocoupler, and by supervising the presence of the short circuit of the output end automatically. CONSTITUTION:While a luminescent element 11 is provided for an output end and radiates with output voltage, a light receiver element 12 is inserted into the DC bias power source 8 of an inverter and is optically coupled with the luminescent element 11 provided for the output end. While specified voltage for output is generated at the output end, the luminescent element 11 radiates, and the light receiver element 12 for receiving the light is conducted, and so the voltage of the DC bias power source 8 can be fed to the base of each transis tor 7, 7'. When the output end is kept in a short-circuiting state, the luminescent element 11 gets not to radiate. Accordingly, the light receiver element 12 gets to be non-conductive, and the DC bias gets not to be fed to the base of each transistor 7, 7' of the inverter 2, and the oscillation stops.

Abstract: PURPOSE:To facilitate degassing, make the clogging of through-holes rare and make it possible to easily clean the through-holes by a method wherein a mold main body, in which a large number of the through-holes are provided by enlarging microscopic non-electrodeposited parts developed at the early stage of electroforming during said electroforming so as to pass through an electroformed layer, is used for blow molding. CONSTITUTION:Spraying liquid is sprayed against a surface, onto which electroforming is wanted to be applied, of a mandrel 5 in order to give electrical conductivity. The spraying liquid is prepared by mixing pasty silver lacquer with polyvinyl chloride lacquer liquid. In the sprayed layer 8, not only an electrically conductive part consisting of silver powder but also microscopic non-electrically conductive parts consisting of polyvinyl chloride lacquer scattered in said silver powder are formed. Since electroforming material 4 electrodeposits well to the electrically conductive parts and badly to the microscopic non-electrically conductive parts, microscopic non- electrically conductive parts as the starting point. As electroforming proceeds, the microscopic non-electrodeposited parts are enlarged so as to pass through an electroformed layer in order to form through-holes 2. After the electroforming on the surface of the mandrel 5 is finished, the electroformed layer 9 is released from the mandrel 5 and used as the mold main body 1 of a mold.
