Title: Thermo-label
Inventor: SAKAI ATSUSHI
IPC: B41M5/36
Filed: 1991-09-06
Abstract: PURPOSE:To obtain the thermo-label which is reversible in display and is repetitively usable by using a resin base material and an org. low-polymer material dispersed into the resin base material as essential components and having a thermosensitive body having the transparency changing reversibly dependently on temp. CONSTITUTION:The thermo-label 1 is constituted by having a tacky adhesive layer 4 on the base 2 surface side of a laminar thermosensitive member 33 having the thermosensitive body 32 dispersed with the org. low-polymer material 31 in the resin base material 30 on a base 2 and further, sticking a separator 5 to the tacky adhesive layer 4. The thermosensitive body 32 is in a white opaque state at ordinary temp. of, for example, <=T0. This thermosensitive body becomes transparent when heated to the temp. between T1 and T2. The thermosensitive body remains transparent even when the thermosensitive body is restored to the ordinary temp. below T0 in this state. Further, the thermosensitive body attains the intermediate translucent state between the max. transparency and the max. opacity when the body is further heated to the temp. above T3. The thermosensitive body restores the initial white opaque state without attaining the transparent state again when the temp. is successively lowered in this state. Then, the thermo-label utilizing such thermosensitive body is repetitively usable.

Abstract: PURPOSE:To obtain printing with excellent picture without allowing the quality deterioration because of unevenness over the surface of photographic printing paper by manufacturing a thermal head in a structure wherein the height of an overglaze layer is made same on positions over heating resistance bodies and over places between the heating resistance bodies. CONSTITUTION:Parts positioned over patterns of thick film resistance bodies 4 and photosensitive resists 5 are removed and, at the same time, the thick film resistance bodies embedded in openings 5' of the photosensitive resists 5 are removed so that the thick film resistance bodies become same in the height with the thick films of the photosensitive resists 5. After this, the thick film resistance bodies are sintered and, at the same time, the photosensitive resists 5 are burnt and removed after gasification. An overglaze layer 6 is then formed by means of screen printing and an anti-wear layer is formed after burning is applied thereon. In forming of the overglaze layer, the height of the overglaze is made higher on positions over the heating resistance bodies 4 than on positions over places between the heating resistance bodies 4. After this, grinding is applied over the surface of the overglaze layer 6, and thereby the height of the overglage layer 6 is made same either on the heating resistance bodies and on the positions over the places between the heating resistance bodies.

IPC: H04N7/32
Filed: 1992-08-04
Abstract: PURPOSE:To multiplex the picture signals of plural channels at a constant transmission rate while holding the picture quality of a high quality. CONSTITUTION:At the time of encoding a picture signal impressed on an input terminal 15 by each dynamic image encoder 11, a target code amount is set at every picture type, and assigned through a signal line 39 so that a big bit rate can be assigned to the picture signal whose movement is violent and a small bit rate can be assigned to the picture signal whose movement is small. Then, the picture signal is encoded by each dynamic image encoder 11, multiplexed by a multiplexer 21, and outputted to an output terminal 29. Therefore, at the time of multiplexing the plural channels, and transmitting the many dynamic image pictures in parallel, the multiplexing of the dynamic images of the highest picture quality can be realized within the permitted range of a transmission capacity in which the inclination of the picture quality can not be generated between the channels.

Abstract: PURPOSE:To obtain a gradational display on liquid crystal by inputting a scanning signal of specific frequency to plural scanning electrodes of a liquid-crystal display panel successively and selectively, and generating plural gradation signals which differ in frequency and making a selection according to display data. CONSTITUTION:Gate circuits 12i (i=1-n) are opened by outputting 1 from a scanning circuit 11 successively and a selection signal VS from a basic pulse generating circuit 15 is outputted as the scanning signal Si. A gate circuit 14i becomes open through an inverter 13i except when a corresponding gate circuit 12i is selected, thereby outputting a nonselection signal VNS. Consequently, the selection signal is outputted only in one scanning period and an unselected state is set in other period to input the Si to scanning electrodes Vi of liquid crystal 16. Data in a display memory 26 are selected 27 successively, black, white, and half-tones among gradations 28j (j=1-m) are specified, and gradation signals T1-T4 of the circuit 15 are selected and inputted to signal electrodes Hj of the panel 16. Inputs to electrodes Vi and Hi are used in combination to display black, white, and half-tones on the panel 16.

Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To absorb variations in the position of mounted components, without making holes in a substrate and having the trouble of soldering by forming a collar in the periphery of a shiled cover and abutting it against a copper foil around the reference potential of the substrate. SOLUTION: First, electronic components 12 such as ICs, LSIs, electrolytic capacitors, and switches are mounted on a substrate 11 provided with printed copper foil circuits. Thereafter, a shield cover 3 is put on these electronic components so that these components fit into the shield cover 3. The shield cover 3 is set on these electronic components, using slits 32 of the shield cover 3 with the outer shape of the electronic components 12 as a guide. Thereby, a collar 31 of the shielding cover 3 is brought into contact with the substrate 11 to realize shielding for the electronic components 12 from an upper copper foil and a gold foil on the substrate. Thus, the shield cover 3 can be assembled merely by placing it on the electronic components 12 with the outer shape of the electronic components 12 as a guide.  Therefore, soldering can be eliminated, and variations in the position of mounted components can be absorbed.

Title: Method of packeting process
Inventor: ICHIMOTO TETSUYA
IPC: H04L29/02
Filed: 1984-10-30
Abstract: PURPOSE:To contain plural data of the same code with a delimiter in a packet and transmit by providing a timer that starts operation on receiving the delimiter and resetting recognition of the delimiter in this time of operation. CONSTITUTION:When the number of received data is judged as less than 256 bytes, and the received data are not delimiter, operation of a packeting timer that watches overall time T1 is started. If data are received again within time t1, the timer is reset. When the next data is not received after lapse of time T1, received data up to that time are packeted. On the other hand, newly received data is a delimiter or the same code with the delimiter, operation of a delimiter judging time of time T2 (T2<T1) is started. If the next data are not received after lapse of time T2, the received data at this time are recognized as a true delimiter. When new data is received within time T2, the timer is reset. That is, the received data is recognized as ordinary data of the same code with the delimiter.

Title: Magnetic head
Inventor: OSAWA YUICHI
IPC: G11B5/31
Filed: 1987-09-14
Abstract: PURPOSE:To obtain good magnetic characteristics by forming a magnetic metallic film and insulating film respectively of an FeAlSi alloy film and Si film. CONSTITUTION:The magnetic metallic film 1 and the insulating film 2 are respectively formed of the FeAlSi alloy film and the Si film. Namely, the Si film is sufficiently higher in electric resistance value than a 'SENDUST(R)' film and is, therefore, capable of preventing the generation of eddy current. Since Si forming the insulating film 2 is also the constituting element of the 'SENDUST(R)' film, the deterioration in the magnetic characteristics is obviated even if the Si intrudes into the 'SENDUST(R)' at the time of the film formation. The magnetic head having the good magnetic characteristics is thereby obtd.
