Title: Optical disk
Inventor: KURODA SUMIO
IPC: G11B7/24067
Filed: 1989-12-11
Abstract: PURPOSE:To use a ready-made objective lens even when using any constituting material for an optical disk by specifying the sum of respective optical path lengths = (thickness)X(refractive index) for a supporting substrate, recording medium and protecting film to a prescribed wavelength. CONSTITUTION:A sum n1d1+n2d2+n3d3 of the respective optical path lengths calculated from thickness d1, d1 and d1 and refractive indexes n2, n2 and n2 of a supporting base 1, a recording medium 2 and a protecting film 3 is made 1.87+ or -0.28mm. As the fundamental configuration of the read only optical disk, the optical path is only the substrate and the optical path length is 1.87+ or -0.28mm. Therefore, by controlling the sum of the optical path lengths of the supporting base, the recording medium and the protecting film so as to be equal with this optical path length, the ready-made objective lens can be used even when using any constituting material for the optical disk.

Title: Lifting sling for cylindrical heavy load
Inventor: SAKAMOTO TOSHIO
IPC: B66C1/62
Filed: 1993-12-22
Abstract: PURPOSE:To handle a cylindrical heavy load by means of only the handling operation of a crane by installing a lifting sling, engaging both ends of this cylindrical heavy load in space between two fixed fingers opened with their lower sides and attached in U-shaped form, in both ends of a beam high down from a hook. CONSTITUTION:At the time of lifting up, a lifting sling is made to go down from the upside of a cylindrical heavy load R on a floor saddle. A clamp arm 4 being opened downward aslant with its own weight comes into contact with this cylindrical heavy load R and rotates with the lowering of the lifting sling. Since a tip part of this clamp arm 4 goes up and engages with an engaging claw 31 at a tip part of a movable finger 3, closing each lower end of two fixed fingers 2a an 2b, it is able to lift up the cylindrical heavy load R. At the time of lowering, the cylindrical heavy load R is put down on the floor saddle. When the lifting sling is left idle, inched in the horizontal direction and the movable finger 3 is pushed outward, the tip part of the clamp arm 4 separates from a claw part of the movable finger 3. In addition, when the lifting sling is wound up, the clamp arm 4 rotates, whereby it comes off the cylindrical heavy load R.

Title: Bit error correction device
Inventor: HIGAKI KENJI
IPC: H04L7/08
Filed: 1989-12-15
Abstract: PURPOSE:To improve the correction effect of a bit error correction circuit up to a level almost close to a theoretical value by synchronizing a counter with a correct frame synchronizing pulse and using an output pulse of the counter as a frame synchronizing pulse thereafter. CONSTITUTION:Since a delay circuit 3 delays an SQ signal 30 by a time corresponding nearly to a preamble 11, an output of the circuit 3 is logical H when a first frame synchronization pulse 20 is outputted and the pulse 20 generated immediately after an FF 51 is set passes through a gate 7 to set an FF 52. When the FF 52 is set, the pulse 20 is blocked by a gate 81 and an output pulse 22 of the counter 4 pass through gates 82, 83 and the pulse is used as a correct frame synchronizing pulse 23. Then the FF 51 is set when the count of the counter 4 is (n-1) and reset when the count of the counter 4 is logical 1 but no effect is given to the FF 52. The pulse at a point of time t4 in waveform diagram is a correct frame synchronization pulse and the output pulse 22 of the counter 4 is used as the correct frame synchronizing pulse.

SOLUTION: A matched plate 1 provided with a hydraulic circuit forming non- pressing bonding part 2, a panel strain preventing bulging part forming non-pressing bonding part 3 surrounding the hydraulic circuit forming non-pressing bonding part 2 and having un-continuous part at a part 3X, a hydraulic pressure introducing part forming non-pressing bonding part 4 extending from the part 3 to the plate edge, and a communicative part forming non pressing bonding part 5 to connect the part 2 to the part 3 is clamped with an upper die and a lower die 7 through a spacer 8 so that non pressing bonding part bulging spaces S1 are formed on both face sides of them, then, the hydraulic pressure is supplied to the whole non pressing bonding parts 2, 3, 4, 5 of the matched plate 1 to body them, thereby making the bulged upper and lower both faces in pressure contact with the both die faces.  Bulging of the part 3 is completed prior to that of the part 3, and the un-continuous part 3X in the part 3 is not bulged, thereby forming an air escaping part 30X inside the panel strain preventing bulging part.

Title: Logic circuit
Inventor: TAKAHASHI SHIGEKAZU
IPC: H03K19/088
Filed: 1987-12-23
Abstract: PURPOSE:To prevent a delay in a logic circuit due to negative voltage noise by providing a bias circuit having a characteristic equivalent to that in a state when the output of an input circuit is at a low level and a driving circuit connected to the said bias circuit. CONSTITUTION:When inputs 1, 2 changes from a low level(L) to a high level(H), the level of the collector of an output transistor(TR) 9 changes from H to L, an L level is supplied to the base of a phase inverting TR 12, which is going to be cut off. In such a case, when a negative voltage noise with a level (lower than the level being the subtraction of a base-emitter forward voltage of the TR 12 and a base-collector voltage of a TR 21 for output low level drive from the base voltage of the TR 12 at a low level) is applied to the output 23, the TR 12 acts to operate from the cut-off state. However, since the collector voltage of the TRs 27, 9 is the same and supplied to the base of a TR 29 for drive circuit, when the negative voltage noise is applied to the output 23, the TR 29 is activated. Thus, the TR 12 keeps the cut-off state, the TRs, 13, 20 for output high level drive are activated and the level of the output 23 changes from L to H.
