Title: Image formation device
Inventor: OIKAWA NOBURO
IPC: B41J2/05
Filed: 1990-08-17
Abstract: PURPOSE:To form an image capable of high recording density without increasing the size of dots or reducing the sharp contrast of a boundary by providing a nozzle which can eject a liquid ink to the surface of an ink carrier and also at least, a nozzle plate which can close a space near a head hermetically. CONSTITUTION:If a heating element 7 for a thermal head 2 which is kept in contact with an ink carrier 3 loaded in a void part, is energized and thereby ink 4 is heated, the low boiling point component of the ink 4 evaporates to generate vapor bubbles and thus a pressure generates. Then the vapor bubbles grow rapidly and not only ink in a nozzle but also even part of the ink retained in the void part are squeezed out and ejected in the form of ink droplets 8. Next, the ink droplets are scattered and attach to a recording sheet 12 in an opposite position to form recording dots. As a nozzle plate 1 is highly rigid, it does not become deformed, if pressed partly, and the ejected ink does not spread widely.

Abstract: PROBLEM TO BE SOLVED: To prevent the needless consumption of a battery and deterioration in the characteristic of a correction optical system by automatically fixing the correction optical system in a predetermined state when a no-shake state is continued for a given time or when the capacity of the battery is lowered to less than a predetermined capacity. SOLUTION: When a power source monitoring means 106 measures a power source voltage and judges that the capacity of a battery of this device is sufficient, a camera shake judging circuit 104 judges whether the camera shake occurs or not, based on a camera shake signal 102 detected by a vibration gyro being a shake detection sensor 101 and outputted from a sensor output circuit 120. In the case of judging that the camera shake occurs, a timer 105 is set to perform ordinary camera shake correction control. When the measured value of the timer 105 reaches a given time during the continuation of a the ordinary camera shake correction control, it is judges that a user forgets to turn off a power source and a fixing means 107 is driven to fix a variable apex angle prism 108 at a predetermined neutral position.  Meanwhile, in the case of discriminating that the capacity of the battery in the device is insufficient, the means 107 is immediately driven to fix the prism 108 at the predetermined neutral position.

Title: Rice boiler
Inventor: ARAI TOSHIO
IPC: A47J27/00
Filed: 1992-08-18
Abstract: PURPOSE:To improve the function of boiling rice by solving such the problems that electricity is early turned off or boiled rice is scorched, by a method wherein a temperature at the end of rice boiling is detected and the rate of an electric current applied to a heater is lessened, following which rice boiling is completed after a fixed time and a second temperature at the end of rice boiling is simultaneously preset. CONSTITUTION:An inner vessel 1 in which rice and water are put is placed on a heater 2 and is heated. The inner vessel 1 is placed in a protective frame 3 and a lid member 4 is openably provided above the protective frame 3. A thermal sensor 5 fitted to the side of the inner vessel 1 detects temperature on the side thereof and outputs a signal to a control substrate 6. A microprocessor is fabricated in the control substrate 6 and it controls heating to different kinds of inputs and determines the amount of rice boiling. In this case, when a temperature detected by the thermal sensor 5 reaches the temperature at the end of rice boiling, heating power is weakened at the rate of an electric current applied to the heater at the time of boiling up, which is smaller than that at a process of keeping the boil, following which a process of steaming boiled rice is done after a fixed time. In addition, when the temperature by the thermal sensor 5 reaches a first temperature at the end of rice boiling, the rate thereof is lessened and the heating power is weakened, and when the temperature thereby reaches a second temperature at the end of rice boiling, heating is shifted to the process of steaming the boiled rice.

Title: Image encoding/transmitting device
Inventor: NISHIWAKI MITSUO
IPC: H04N19/00
Filed: 1990-08-21
Abstract: PURPOSE:To shorten transmission time by letting transmission/reception parts have frame memories and switching devices, respectively, in addition to frame memories they have, respectively. CONSTITUTION:In this image encoding/transmitting device, a transmission side has afresh a frame memory 1, a control circuit 2 and a switching device 3, and a reception side has afresh a frame memory 4, a control circuit 5 and a switching device 6. Therefore, an identical image for one frame is stored in a transmission/reception part. When refreshing operation is requested, a predicted value is read from the frame memory provided afresh, so refreshing information alone is transmitted to the reception part, dispensing with the necessity of transmitting an image for one frame again to the reception part. Thus, the content of the frame memory of transmission/reception can be refreshed in a short period of time.
