Title: Ink-jet recording device
Inventor: OKADA JIYUNICHI
IPC: B41J2/165
Filed: 1979-05-02
Abstract: PURPOSE:To prevent ink from being dried and stabilize performance against the change of the difference in height by shutting off from the air both a passage communicating an ink-impregnated material of an ink-supplying system with the air by a tank cap and the jet orifice of a head by a nozzle cap. CONSTITUTION:On recording, a nozzle cap 7 and a tank cap 8 being removed, a jet nozzle 6 and an ink-impregnated material 3 are opened to the air. Internal pressure of the part of the nozzle 6 is set at about 0-60cm H2O based on the atmospheric pressure, thereby flow-out of ink and flow-in of air being prevented. The difference in height H is regulated to be + or -10cm approx. based on the level of the nozzle, and the capillary force of an ink tank 1 and the system of the ink-impregnated material 3 is made to produce the pressure of about 0-70cm H2O to attain stabilization. When the ink is not jetted from the nozzle 6, the nozzle cap 7 and the tank cap 8 are moved to prevent the drying of ink, thus the diffusion of ingredients of ink from the ink system to the air being prevented.

Title: Patterning method for tin oxide film
Inventor: IMAI MIZUHO
IPC: H01B5/14
Filed: 1989-03-07
Abstract: PURPOSE:To prevent the irregularity of patterning accuracy and a drop in yield by forming a tin sulfide film on a substrate, patterning the film via a chemical etching process and then heating the tin sulfide film for forming the pattern of a tin oxide film. CONSTITUTION:A film 2 containing tin sulfide is formed on a substrate 1 and a photoresist 3 is applied to the film 2. Furthermore, the film 2 is etched with an alkaline water solution using a photo-lithography method, and then is heated. As the film 2 containing the tin sulfide is formed on the substrate 1 and etched with an alkaline water solution, the chemical etching of the film 2 with the alkaline water solution becomes easy and that etching accuracy becomes high. Also, as the heating of the patterned tin sulfide film 2 enables the change of the tin sulfide film 2 into an oxidized film 4, the pattern of high accuracy obtained with the tin sulfide film 2 turns into a tin sulfide film 4 as it is. According to the aforesaid construction, it becomes easy to carry out a patterning process and form a fine pattern of high accuracy.

Title: Generator for substituting substance for smoke
Inventor: NAKATSUKA SETSUJI
IPC: G05D21/00
Filed: 1993-02-19
Abstract: PURPOSE:To reduce the dispersion of mist density control by generating mist by moving either a heater or liquid level of a container in the up-and-down direction, and soaking the heater in a liquid. CONSTITUTION:The mist is generated by heating the liquid 2 in the container 1 locally. The liquid 2 is fed to the container 1 and a ceramic heater 3 for soldering iron whose temperature is adjusted at the one over the boiling temperature of the liquid 2 is connected to the rod of a cylinder 4 via members 5, 6. The heater 3 is soaked in the liquid 2 by moving in the up-and-down direction with the cylinder 4, and the liquid 2 is heated locally by the heater 3, which generates the mist. At this time, since the temperature of the heater 3, the stroke of the cylinder 4, and a cycle time in movement in the up-and-down direction are set at fixed values, the generated amount of mist can be fixed. Also, since the heater 3 is not brought into contact with the liquid 2 when the temperature of the heater 3 is increased, no mist can be generated. Thereby, it is possible to prevent the increment/decrement of the amount of mist for the turning on/off of the cylinder 4 from being delayed.

Title: Dc voltage detection circuit
Inventor: KIDO SUSUMU
IPC: G01R19/25
Filed: 1986-03-14
Abstract: PURPOSE:To make it possible to confirm whether DC voltage to be measured is a prescribed voltage, by normalizing the difference of the polarity of DC voltage to be measured by an operational amplifier and a resistor to read the same as digital data. CONSTITUTION:When the nominal voltage value of DC input voltage E1 is inputted, resistors R1, R2 are selected so that the output voltage Ex1 of an operational amplifier 1 becomes a constant value to normalize voltage E1. Similarly, the input voltage -E2 of the operational amplifier 2 is also normalized. An AD converter 3 outputs the digital data Dx1 corresponding to the normalized output voltage Ex1 on the basis of the chip selection signal 100 and reading signal 102 from a digital data reading circuit 5. Similarly, an AD converter 4 outputs digital data Dx2. Therefore, in both positive and negative cases of DC input voltage, when voltage of which value is alpha-times the nominal voltage value is inputted, a value alpha-times the digital data corresponding to the nominal voltage value is outputted as the output digital data of the converter 3 or 4. That is, regardless of the magnitude of the polarity or voltage absolute value of DC voltage, the ratio to the nominal voltage value can be judged from the digital data value by the circuit 5 and it can be confirmed whether voltage to be measured has a prescribed voltage value.

Abstract: PURPOSE:To provide a prevention of malfunction of a direct key and maintain its safety characteristic in a heating and cooking device in which heating and cooking operations are performed by the direct key by a method wherein the direct key is constructed to have a double-key structure with different two independent key contact points. CONSTITUTION:A direct key is constructed to have a double-key with two independent key contact points and two key operating signals outputted from the key contact point of the double-key are separately inputted to a control part 3 under a key operation of the direct key. The control part 3 controls a heating and cooking part 1 on the basis of two key operating signals outputted from the direct key under a predetermined heating condition. Accordingly, the control part 3 judges that the direct key is depressed only after the two key operating signals are inputted and ten starts a cooking operation at the heating and cooking part 1 under the predetermined heating condition. With such an arrangement as above, it is possible to prevent an erroneous operation of the direct key.

Title: Motor-driven toothbrush
Inventor: KITAMURA YOSHIHIRO
IPC: A61C17/22
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To prevent a rotary base from being broken and retain usability of a toothbrush by forming the toothbrush so that the outer periphery of the rotary base of the rotary brush brushing teeth while rotating is positioned at almost the same height with the top of an attachment holder. SOLUTION: In this motor-driven toothbrush, a rotary brush 7 is turned by a specified angle by driving a motor 2 to brush teeth by the revolution of the motor. There is a fear that the motor-driven toothbrush drops during use by mistake but since there is almost no level difference between the outer periphery of the rotary base 8 and the top 11 of an attachment holder 6, the top 11 of the attachment holder is hit together with the rotary base 8 and hence, the rotary base 8 can be prevented from being broken. Further, since the diameter of a round part 13 is made smaller than the diameter of the rotary brush 7, even if the top 11 is flush with the outer periphery of the rotary base 8, the usability in the mouth is favorable.
