Title: Liquid jet recording device and its control method
Inventor: WATANABE KENJIRO
IPC: B41J2/175
Filed: 1990-02-13
Abstract: PURPOSE:To make it possible to stop driving of a recording head when a rising rate of temperature is larger than a desired temperature rising rate by providing a control unit which controls a recording head and/or liquid jet recording device in response to temperature change of the recording head. CONSTITUTION:By detecting temperature of a recording head, a value which is Temp 1 is obtained. After resetting, a timer is started, and counting is done as Time 1. When printing is not completed, it is decided whether Time 1, the time which is being counted, is longer than 10 sec or not. In this case, if Time 1 does not reach 10 sec, this process is repeated. When Time 1 exceeds 10 sec, temperature of the recording head is detected, and a value for Temp 2 is obtained. The value of Temp 1 is subtracted from the value of Temp 2, and it is decided whether the obtained value is not less than 10 deg.C or not if this value is not more than 10 deg.C, the value of Temp 2 is made to be the value of Temp 1, and the same process is repeated. When this value exceeds 10 deg.C, it is decided that non-discharge generates, and a display (alarm) of non-discharge is given to the device main body, etc., and the device is turned off.

Title: Writing device of servo track information
Inventor: SATOU TADASHI
IPC: G11B5/596
Filed: 1980-03-13
Abstract: PURPOSE:To enhance the float-up performance of a servo track information writing head and thus ensure a writing of a high-quality servo track information, by attaching much importance to the float-up performance of the writing head when deciding the angle of attachment of the writing head. CONSTITUTION:The angle is set at 50 deg. that is formed by a cross between the head gap 22 and the shifting direction 24 of the servo track information writing head 21. Owing to this angle of 50 deg., the angle formed by a cross between the orthogonal line 45 of the head cap 22 of the head 21 at the inner circumference and the track tangent direction line 46a is set at 51 deg. that is smaller and more stable than the conventional angle. However, the angle formed by a cross between the line 45 at the outer circumference and the track tangent direction line 46b is set at 52 deg.. Thus an average and stable float-up is secured between the inner and outer tracks.

Title: Method for removing astringency of astringent persimmon and preserving the persimmon
Inventor: KANEKO YUKI
IPC: A23B7/00
Filed: 1990-02-15
Abstract: PURPOSE:To enable mass-production of sweetened persimmons having high preservability at a low cost while preventing the development of black spot and the deterioration of the luster and color of the persimmon by sealing astringent persimmons in a packaging material and immersing the packaged persimmons in water. CONSTITUTION:Astringent persimmons are sealed in a packaging material preferably impermeable to water and air and the persimmons are left standing while preventing the contact of the astringent persimmons in the package with water. When the persimmons are left standing in the above state for about 2 months, the astringency of the astringent persimmon is removed to obtain a persimmon having moderate sweetness and proper hardness without causing the excessive softening of persimmon while preventing the development of black spot and the deterioration of the luster and color of the persimmon. The astringency-removing effect and the preservation effect can be improved by sealing an inert gas other than air, e.g. CO2 gas or N2 gas together with the astringent persimmons in the packaging material. The above effects are further improved by using an absorbent such as deoxidation agent to absorb the gas generated from the astringent persimmon.
