Title: Manufacture of back plate and front plate for plasma display panel
Inventor: ASAHI KOICHI
IPC: H01J11/34
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To control an expansion/shrinkage quantity of a glass substrate itself in burning to nearly zero by finding a cooling speed, at which the substrate is not expanded/shrunk substantially in a burning process, in gradual cooling on the basis of expansion/shrinkage quantity measurement values before and after a glass substrate burning process matching a burning profile at each cooling speed and performing each burning process at the found cooling speed. SOLUTION: At a cooling speed in cooling from a peak temperature, which is a maximum temperature for burning and corresponds to a keep temperature Tk, to a strain point Ts of a glass substrate, a burning process is carried out previously, and an expansion/shrinkage quantity of the glass substrate in burning in each profile matching a cooling speed Tv is measured. From the found measurement data, a cooling speed Tv, at which the glass substrate is not expanded/ shrunk substantially in the burning process, from the keep temperature Tk to the strain point Ts is calculated. At the found cooling speed Tv, cooling from the keep temperature Tk to the strain point Ts is carried out.

Abstract: PURPOSE:To enhance operability in opening a cover, by a system wherein a cover is automatically opened when cover opening is designated. CONSTITUTION:A main controller checks whether a cover open/close switch 10 is turned ON. When the switch 10 is turned ON, the controller stores the positions of a carriage 36 and a type wheel 37 at that moment into predetermined addresses in a RAM 54, moves the carriage 36 to such a position that a ribbon 40 and the type wheel 37 can be easily replaced, for example, a central position, and drives a cover motor 14 of a cover opening and closing mechanism 11 to rotate, thereby turning a gear 12 in the direction of arrow A to open the cover 3. It is discriminated whether or not the switch 10 is again turned ON, and a stand-by condition is maintained until the switch 10 is again turned ON. When the switch 10 is again turned ON, the controller drives the motor 14 to rotate, thereby turning the gear 12 in the direction of arrow B to close the cover 3.

Filed: 1982-07-12
Abstract: PURPOSE:To simplify a titled circuit, by frequency-dividing a frequency of an input signal into a half at the transmission side, differentiating the result at the receiving side, and delaying the sampling period to decrease the transmission frequency band. CONSTITUTION:After a digital input signal of transmission terminals ch1-ch4 is amplified and waveform-shaped, the frequency is divided into a half at a frequency division circuit section 2, the signal width is doubled, sampled with a clock pulse from an oscillator 9 at a P/S conversion section 4, outputted serially to signals at each channel and transmitted to a remote place. The signal is inputted to an S/P conversion section 7 at the receiving side, where the signal is sampled and the result is outputted at each channel. The information having the same interval as the digital input signal is reproduced by differentiating the leading and trailing edges of the signal at a differentiation circuit 8.

Abstract: PROBLEM TO BE SOLVED: To use one face of a cleaner, when the other face is soiled by cleaning work, to reduce the frequency of work suspension for exchanging a sheet member, by composing a base body so that a number of sheet members can be attached onto a sheet retaining face equipped on the base body. SOLUTION: Every time a handle 2 is rotated by 90 deg., an engaging protrusion 2a1 and an engaging dent of a cylindrical part are engaged together to produce a click to enable a user to easily recognize the rotation angle of the handle 2 in this embodiment. After setting a position, the handle 2 is gripped by a hand putting the palm on the outer face 2b1, and, since the handle 2 is in a curved shape, the hand gripping the handle 2 is separated from a used part (in this case 8a) of a sheet member 8. Consequently even in a condition the surface part 8a of the sheet member 8 is pressed against a part to be cleaned, the hand gripping the holding part 2b does not touch the part to be cleaned to make the cleaner extremely easy to handle.

Abstract: PROBLEM TO BE SOLVED: To increase the speed of data communication and to reduce the power consumption by converting encoded data from a main body communication part into a radio wave signal having minimum transmission power and outputting it to an antenna part and converting a radio wave signal received by the antenna part into reception data and transferring the data to the main body communication part. SOLUTION: A small-power radio wave transmission and reception part 2 converts the transmission data transferred from the main body communication part 1 into a radio wave signal, which is then transmitted through the antenna part 3. At this time, the small-power radio wave transmission and reception part 2 encodes the transmission data transferred from the main body communication part 1 and converts the encoded data into the radio wave signal so that its transmission power becomes minimum at the time of transmission from the antenna part 3. Further, when the antenna part 3 receives data as a radio wave signal, the small-power radio wave transmission and reception part 2 converts the received data into received data which can be read in by the main body communication part 1 and transfers the data to the main body communication part 1.
