Title: Synchronizing detection circuit of television receiver
Inventor: OGAWA MASUMI
IPC: H04N5/455
Filed: 1986-04-10
Abstract: PURPOSE:To stably obtain a detection signal by forming the oscillation signal of a voltage controlled oscillator as a signal having a frequency apart from that of a video intermediate frequency signal. CONSTITUTION:A multiplier circuit 8 multiplies the oscillation signal of a PLL circuit synchronously with a video intermediate frequency signal with a video intermediate frequency phase-shifted and a detection signal is obtained at a detection signal output terminal 9 as the output signal of the multiplier circuit 8. Since a voltage controlled oscillator 10 oscillates a frequency signal being a half the intermediate frequency fp at free oscillation, the oscillation signal fp/2 has a nearly a half the frequency of the video intermediate frequency signal obtained at an input terminal 1. Even when the oscillation signal is leaked from the external terminal for mounting an oscillation frequency deciding element 10a into the input video intermediate frequency signal, since their frequencies are parted, the PLL circuit comprising the voltage controlled oscillator 10 is not self-locked to the oscillation signal and a frequency signal always stable is obtained as the output signal of the voltage controlled oscillator 10. Thus, the multiplication signal of the circuit 8 becomes a detection signal with stable detec tion and an excellent detection signal is obtained at an output terminal 9 stably.

Outside air is circulated in a closing loop shaped pipe passage in which the adsorbing material 12 is passed, and thereby, the temperature of the outside air is raised by heating of a heater 14.  Hydrocarbon which is adsorbed on the adsorbent 12 is oxidized by air having a high temperature, and then it is cracked into water and CO2 .

Title: Process controller
Inventor: KOGURE YOICHIRO
IPC: G05B11/42
Filed: 1987-04-06
Abstract: PURPOSE:To minimize the control delay by securing the balance between the integration value of an integration element and the value of the relevant control signal under the fixed conditions when the deviation between the measurement value signal and the target value has inversion of its polarity. CONSTITUTION:A polarity inversion detecting means 34 detects the polarity change of deviation a between the target value a0 act by a target setter 18 and the measurement value signal (a). Then an integration value balance means 28 is actuated. In other words the means 38 obtains the integration active signal (d) of that time point to preserve it as a signal d0 after the means 34 detects the polarity change of said deviation DELTAa. Then it is decided whether the polarity of the deviation DELTAa is inverted or not to the negative polarity from the positive one. If so, the control signal (c) is compared with the signal d0 when said polarity is changed. When it is decided that the signal d0 is larger than the signal (c), the signal (d), i.e., the output of an integration element 22 has coincidence (balance) with the level of the signal (c) of that time point in place of the signal d0 by means of a switch means 35.

Title: Jig for firing electronic component
Inventor: SAKASHITA KEIICHI
IPC: H01G13/00
Filed: 1989-03-31
Abstract: PURPOSE:To improve productivity by a method wherein a ceramic coating layer, having the crystal grain diameter of 1 to 90mum or above and the content of grain diameter within the range of average grain diameter + or -20% of 90% or more, is provided. CONSTITUTION:The first layer is a flame spray coating layer having the crystal grain diameter of 1 to 90mum. The flame spray coating layer is subjected to generation of cracks when it has crystal grain diameter less than 1mum, and on the other hand, film strength becomes weak if the crystal grain diameter is 90mum or above, and it becomes easier to exfoliate. The ceramic grains which form the second layer have the average grain diameter of 20mum or above, and they contain the grain diameter content of 90% within the range of average grain diameter + or -20% when the average grain diameter is 20mum or less, the first layer and the material to be fired are easily brought into contact with each other, and there is little effect even when the second layer is formed. Also, when the grain diameter of the average grain diameter of + or -20% or less than 90%, the recesses and projections on the surface of a coarse grain layer become larger, the above-mentioned contact is lessened, and the contraction of the material to be fired is hardly made uniform. As a result, the contact between the second layer and the material to be fired is lessened, and the infiltration diffusion into the first layer can be prevented by the thickness of the layer.

Title: Method for preventing forgery of composite recording carrier
Inventor: TANAKA HIROKAZU
IPC: G11B7/24012
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a forgery prevention method which inhibits a normal access as long as an optical recording part is not correctly paired with an IC part by changing the physical or logical position of the information to be recorded in a recording area other than a 1st recording area in based on the ID inherent to each recording carrier that is recorded at a specific position of the 1st recording area. SOLUTION: In the composite recording carrier where the 1st to n-th recording areas are arranged on the same carrier, an ID inherent to each carrier is recorded at a specific position of the 1st recording area. When the information is recorded or reproduced in a recording area other than the 1st recording area, the ID is reproduced at the specific position and the physical or logical position is changed for the recording/reproducing operations of information based on the reproduced ID. For instance, two elementary files (EF1, EF2) 61 and 62 are previously produced at an IC part of a hybrid card and at the inside of a master file MF 60. Then a card inherent ID is recorded on the file 62 when a card is issued.

Title: Caisson joint
Inventor: OKABE MICHIMASA
IPC: E02D25/00
Filed: 1994-04-21
Abstract: PURPOSE:To prevent earth and sand on the rear side from flowing out by forming a longer belt-shaped member by a laminate and fixing one side of the laminate in the longitudinal direction with one caisson and setting the other side as a free end and placing the internal side in contact with the end face of the other caisson. CONSTITUTION:Rubber is pressed down on both faces of fiber so that they may be laminated, thereby forming a longer belt-shaped body with a laminate 4 thus laminated. One side of the laminate, which serves as an anchor 5, is fixed with one rear side of an adjacent caisson 8, thereby forming a joint material 1 while the other side is adapted to be a free end whose internal surface is arranged to be a contact part 6 which comes in contact with the rear side of the other caisson 8. When the caissons 8 are moved by differential settlement after the installation of the caissons 8, it is possible to comply with the movement in every direction since the joint material 1 is arranged to be fixed with only one caisson 8. The joint material 1 is bendable with an earth pressure so that its contact part 6 may be joined with the caisson 1, thereby keeping its joint action. This construction males it possible to allow the joint material to follow with the behavior of the caissons 8 and prevent a back-filling material from flowing out.

Abstract: PURPOSE:To measure a proper point on a work automatically by grasping the surface shape of the work according to an attitude such as working line coordinates and changing the position of a sensor for machining automatically according to the moving direction of a working head. CONSTITUTION:The surface shape of the work W is decided according to the coordinates of working lines K(K1-K3) and the attitude of the working head, and the sensor 20 for machining is moved according to the moving directions A, B, and C of the head 1 and the surface shape of the work W to measure a 1st point on the work W in the front in the moving direction or measure a 2nd point on the work W sideways in the moving direction.
