Title: Water absorbing sheet for leak prevention
Inventor: NODA RYOHEI
IPC: B01J20/28
Filed: 1990-10-11
Abstract: PURPOSE:To improve water absorbing rate, water absorbing amount and non-water permeability, make possible the early detection of a water leaking spot and flame protection by constituting the subject water absorbing sheet with a bottom thin leaf paper with a polyethylene-laminated layer on both surfaces, a mixed layer of higher water-absorbing polymer resin, a water absorbing coloring agent and a flame protecting agent, and an embossed laminated layer with an upper thin leaf paper. CONSTITUTION:A powder mixed layer 4 of uniformly mixed polyacrylic acid high water-absorbing resin, water-absorbing, coloring agent and magnesium hydroxide (flame protecting agent), is formed on a bottom thin leaf paper 2, on both surfaces of which polyethylene is laminated 3. Then an upper thin leaf paper 5 is placed over the mixed layer 4 and this laminated product is thermally heated and pressed using an embossing roll for embossing process. A water leak preventing sheet does not use unwoven cloth so that the water-absorption rate is not reduced, and besides, the water-absorbing coloring agent is used so that if a small amount of water leak occurs, its early detection is possible. Thus any appropriate remedial procedures can be taken at any time when water leak occurs. In addition, if fire breaks out due to over-heating or a fire source touches the paper or fire happens to occur, the thin leaf paper, treated for flame protection, no longer catches fire.

Title: Method for driving liquid crystal display device and its driving circuit
Inventor: FURUBAYASHI YOSHINORI
IPC: G02F1/133
Filed: 1989-10-18
Abstract: PURPOSE:To suppress the influence of driving frequency due to the resistance of an electrode and the capacity of liquid crystal and to attain uniform half-tone display by alternating a case for shifting the impression period of a selected voltage to the leading edge of a scanning period and a case for shifting he impression period to the trailing edge in each scanning period. CONSTITUTION:The impression order of the selected voltage and a bias voltage based upon a half-tone level is alternated at every scanning period. Thereby a voltage effective value to be impressed to picture elements is reduced at its voltage loss due to the distortion of a waveform and a change in the driving frequency due to a display pattern can be made equivalent to the case of binary display. Since plural fields is used as a display unit and a method for displaying a half-tone by the combination of ON and OFF fields is also used, the half-tone of higher multi-gradation can be displayed. Consequently display quality equivalent to binary display can be obtained also in the half-tone display due to pulse width modulation.

Title: Switching circuit
Inventor: TANAKA SATOSHI
IPC: H03K17/60
Filed: 1984-12-24
Abstract: PURPOSE:To obtain a switching circuit with excellent transmitting characteristic by detecting the characteristic charge of a transistor (TR) forming a differential amplifier and correcting the transmitting characteristic based on the change. CONSTITUTION:Positive feedback is applied to a base of a TR Q4 in a white clip circuit 1' via TRs Q5, Q6, Q7. When an input video signal Vin approaches a white clip level, the switching from the TR Q3 to the TR Q4 is quickened. That is, the linearity of the transmission characteristic of a differential amplifier is improved. Then the input signal Vin is fed to a TR Q11 forming an RF modu lator without losing the linearity. A bias voltage VB obtained via a TR Q10' from a circuit formed similarly as the clip circuit 1' is fed to the TR Q12. Thus, the switching circuit with excellent transmission characteristic is obtained.

Title: Ink jet recorder
Inventor: NITTA TETSUHIRO
IPC: B41J2/165
Filed: 1989-10-17
Abstract: PURPOSE:To perform good recording stably by a method wherein an opening closing means which interrupts or opens an interconnecting state of a supply passage interconnected to both a recording head and an ink tank is made to execute at least two recovery operations which are different in an operation state. CONSTITUTION:Ink 1 is supplied to a head 1 from an ink reserving part 90 via an opening and closing valve. In recovery, the ink and/or air are sucked from a recording head 1 with a pump 26 via a cap 22 to be stored in a waste ink reservoir 91. Since recovery of ordinary discharge inferiority such as increase of viscosity of the ink at an ordinary nozzle tip, a slight amount bubbles of the nozzle, etc. is sufficed only by sucking the ink from the nozzle, suction by J wherein sucking operation is 1-2 times preformed is performed. Since it is required that a great amount of ink and/or air are sucked when an ink cartridge and the head are exchanged, suction by I is performed and thereafter, suction by J is performed. Selection of both modes is executed with a cam structure.

The vector Zk is generated when a low-speed remote measurement information bit W is encoded by the vector Y. The encoded remote measurement information is added to a data flow for every element with no increase of the data transmission speed and included in every element of a data signal. This data is recovered when every bit is checked by means of a synchronous correlation function.
