Title: Clamp circuit device
Inventor: TSUJI KIYOSHI
IPC: H04N9/72
Filed: 1988-05-30
Abstract: PURPOSE:To realize direct current restoration with less offset shift through simple circuit constitution by clamping a line sequential signal consisting of the repetition of plural line sequential signals separately by every one of said plural line sequential signals by the timing of each line signal, and leading it to a common buffer through a switching device. CONSTITUTION:Repeated line sequential color difference signals R Y, B-Y are impressed to the bases of transistors TR Q3,Q4 through clamping capacitors C1, C2. Then, since clamp pulses CP-R, CP-B are impressed to the bases of the TR Q1, Q2 at the OB parts of the color difference signals R-Y, B-Y, and the levels of the OB parts are made equal to the level of reference voltage Vs, even if the offset shift of  v exists between the line sequential color difference signals R-Y, B-Y, said shift is canceled. The color difference signals R-Y, B-Y in which this shift was canceled through buffers 25, 26 are inputted to the buffer 28 through a switching circuit 27 switched by a switching pulse FH/2, and the line sequential signal whose offset was canceled and which was direct current restored is outputted from an output terminal.

Title: Thermal transfer medium
Inventor: NAGAHAMAYA YUUJI
IPC: B41J31/00
Filed: 1988-06-01
Abstract: PURPOSE:To perform high-quality printing by allowing a release layer which develops foams in a molten state to exist between a base layer and an ink layer, and forming the ink layer in a discontinuous phase under a solid state and in a continuous phase under a molten state. CONSTITUTION:An ink ribbon 6B consists of a release layer 22A which develops foams in a molten state at about 100 deg.C existing between a base layer 20 and an ink layer 21A. In addition, the ink ribbon 6B is so designed that the ink layer 21A becomes discontinuous under a solid state and continuous under a molten state. If this ink ribbon 6B is fed to an area below a thermal head 8 in such a manner that the ink ribbon 6B is overlapped on paper 19, and the ink ribbon is heated by the heating of the thermal head 8, the ink layer 21 of the heated part melts and becomes continuous. In addition, if the release layer 22A with a higher melting point melts, foams develop simultaneously to peel off the part of the ink layer 21A. This results in the pressing of the paper 19 and the subsequent attachment of said part to the protruding part 19A and recessed part 19B of the paper. Thus high-quality printing is ensured even if the smoothness of the paper surface is inferior.

IPC: G03F1/54
Filed: 1990-05-24
Abstract: PURPOSE:To prevent the generation of size defect and size variation and to allow the control of film thickness by etching by providing light shieldable thin films selectively only in the parts where insulatable thin films do not exist, thereby forming light shielding patterns. CONSTITUTION:The light shielding patterns are formed by providing the light shieldable thin films 7 selectively only in the parts 6 where the insulatable thin films 3' do not exist (the parts removed by etching). The light shieldable thin films 7 are formed selectively in the parts where the insulatable thin films do not exist in succession to the pattern formation of the insulatable thin films 3' in such a manner, by which the stress uniform over the entire surface are applied and the generation of the size variation and size defects is suppressed. The insulatable thin films 3' exist in the side parts of the light shielding patterns 7 and these parts are not exposed and, therefore, the etching is entered only from the upper surface of the light shielding patterns 7 even if the etching for correcting the film thickness is executed after the completion of the mask. The film thickness of the light shielding patterns 7 is thus controlled without changing the patterns.

Title: Suspension control device for vehicle
Inventor: KIKUMA NOBUHIRO
IPC: B60G17/015
Filed: 1994-05-25
Abstract: PURPOSE:To let riding comfort and control stability be compatible with each other when a vehicle is running over bad roads by providing the control device with a function for setting threshold values for positive and negative acceleration as a reference for setting damping force depending on a road surface condition, and with a function for setting a condition of damping force depending on the positive and negative acceleration in the case of bad roads. CONSTITUTION:The control section 36 of an electronic suspension controller 25 operates the magnitude of positive and negative acceleration detected by a positive and negative acceleration sensor 19, and their change rate, and a bad road detection counter 38 counts the number of times that the absolute values ¦G¦ of positive and negative acceleration exceed each specified limit. Furthermore, a road surface condition is judged with the aid of a memory section 37 and a bad road detection timer 39, and the threshold values of positive and negative acceleration as a reference for setting the damping force of a suspension mechanism for bad roads are so set as to be higher than those for good roads. Besides, in the case of bad roads, when actual acceleration is less than the threshold values of positive and negative acceleration which are set somewhat high, clamping force is set at a soft condition, when actual one is around the threshol values, damping force is set at a medium condition, and actual one exceeds the threshold values, damping force is set at a hard condition. Riding comfort and control stability can thereby be compatible with each other through fine control.

Title: Discriminating circuit for code error rate
Inventor: ARAI MASANORI
IPC: H04L1/24
Filed: 1981-08-28
Abstract: PURPOSE:To discriminate error rate with a simple constitution, by counting code errors of two times parted longer time than a consecutive time of the code error due to a burst-like cause and outputting to a shift register when the error exceeds a prescribed value. CONSTITUTION:When a code error pulse (a) is inputted to a counter 2, the counter 2 counts pulses having code errors while a low speed clock pulse (b) from an oscillator 6 remains at 0 level. If the count value of this unit time is more than a prescribed value set to the counter 2, a pulse (c) of level 1 is transmitted to an FF12. The FF12 stores pulses of level 1 or 0 inputted from the counter 2 every time the pulse (b) of level 1 from the oscillator 6 is inputted and shifts the pulses to an FF13. Every time the pulse (b) of level 1 is inputted to the FF13, data inputted from the FF12 is stored and transmits the data to an AND gate 5. The gate 5 derive an AND of outputs from the FF12, 13 and generates an alarm output 9 when the AND is 1.

Title: Air conditioner
Inventor: NEGORO KOICHI
IPC: F25B29/00
Filed: 1986-06-11
Abstract: PURPOSE:To obtain an air conditioner capable of intermittently carrying out a stable operation by controlling the air flow rate of a blower in accordance with the temperature of air flowing into an evaporator. CONSTITUTION:When the temperature of air flowing into an evaporator 7 is lowered to a value lower than a first predetermined temperature, a temperature adjustor 14 detects it, and its contact 14b is opened and a coil 9a0 is excited to open a solenoid valve 9a. For this reason, a coolant is condensed at both condensers 4 and 8. A blower 3 is operated so that an indoor air temperature becomes constant. When the heat radiation amount of the condenser 4 becomes large and the room temperature becomes lower than a second predetermined temperature, the contact 15b of a temperature detector 15 is opened, and the blower 3 is stopped. When the temperature of air flowing into the evaporator 7 becomes higher than the second predetermined temperature, the contact 15b of the temperature adjustor 15 is closed. Thus, (a) contact 105a of an electromagnetic contactor 105 is closed, and the air flow rate of the blower 3 is controlled so that the temperature of air flowing into the evaporator 7 becomes constant. Since the air flow rate of the blower 3 of the condenser 4 is controlled by the temperature of air flowing into the evaporator 7, the variation in the room temperature is reduced.
