Title: Track interpolation type scroll display device characterized by overcurrent protection of display lamp
Inventor: TOKIMOTO TOYOTARO
IPC: G09G3/20
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To prevent an overcurrent from flowing to a lamp and to prevent it from breaking when an abnormal signal which is not a pulse signal is inputted to the enable terminal of a lamp driving circuit. SOLUTION: A blinking pulse signal BCK inputted to the enable terminal Enb of a lamp driving IC 68 drives and blinks an LED lamp in a short cycle to make the lamp synchronize with this. An integration circuit 70 inverts and outputs a level signal generated by integrating the blinking pulse signal BCK and averaging its pulse level with time, to the output terminal 74c of an operational amplifier 74. Through a current value setting terminal 70, the current value of the driving current of the lamp is increased or decreased and set according to the signal level at the output terminal 74c and the driving current is made smaller as the lamp ON period of the blinking pulse signal BCK is longer. Here, even if a signal which turns ON the lamp continuously is inputted to the enable terminal Enb by mistake, an overcurrent of the LED can be prevented to protect the lamp against breakage.

Title: Data processing terminal unit
Inventor: HITOMI MASAAKI
IPC: G06F13/00
Filed: 1979-09-07
Abstract: PURPOSE:To make it possible to transmit an equal number of specific codes evenly by normally treating specific codes in off-line operation while invalidating specific codes, which are considered to be ineffective, in on-line operation. CONSTITUTION:In on-line operation, data are transmitted via transmission line 7 and, after being converted into parallel codes via series-parallel converter 8, sent to buffer 3 via multiplexer 2. Strobe signal STB' from converter 8, on the other hand, is sent to buffer 3 by way of OR gate 4 and NAND gate 5. At this time, detecting circuit 10 compares the output code of ineffective code generator 9 to a code generated by converter 8 and, when the both agree, closes gate 5. Therefore, only when a specific code considered to be ineffective arrives, the input of signal STB' to buffer 3 is inhibited in on-line operation and the specific code outputted from circuit 8 is treated as ineffective one without entering ineffetive buffer 3. Thus, an equal number of specific codes are only inserted evenly in program generation.

Abstract: PROBLEM TO BE SOLVED: To provide the effective photoelectric conversion efficiency and to make the manufacturing cost inexpensive by separating the structure, wherein at least a plurality of columnar structures formed in a semiconductor crystal base material, a part of the semiconductor base material containing a porous layer and a supporting substrate are laminated as the constituent elements. SOLUTION: Light 3, which is applied at the time of anodization reaction, is irradiated from the rear surface of an n-type (100) Si crystal base substance 1 or base material, and the anodization reaction is performed. The anodization conditions are largely changed instantly, and a layer 4 having the large porous degree is formed by the relatively short-time reaction. B-doped glass 5 is applied. A p-type diffused layer 6 is formed in an n-type Si layer 11 through an ordinary diffusing process. After the B-doped glass 5 is removed, a (p) electrode 7 is attached. Furthermore, a grass plate a is bonded. The layer having columnar holes 2 is mechanically removed from the n-type (100) Si crystal base substance 1 of the base material as a unitary body together with the glass plate 8.  The layer 4 having the large porous degree can be separated with a breaking plane 40 as the boundary since the layer 4 is mechanically weak.

Title: Waveform shaping circuit of deflecting voltage
Inventor: SHIMURA MASAYUKI
IPC: H04N5/7826
Filed: 1983-06-27
Abstract: PURPOSE:To prevent tracking shear at the time of specific reproduction by integrating deflecting voltage controlling the deflection of bimolph plates to remove a sharp portion of a waveform and changing the characteristics of integration in accordance with the amplitude of the deflecting voltage. CONSTITUTION:Saw-tooth deflecting voltages (c), (d) having amplitude corresponding to reproducing modes are outputted from a deflecting voltage generator 1 and applied to integrators 6, 7. The integrators 6, 7 are determined at their integration characteristics by control pulses (g), (h) having frequency corresponding to the reproducing modes. Integrated outputs (e), (f) preventing the linearity of the deflecting voltages during the video reproducing from being lossed are extracted from the integrators 6, 7. Error outputs indicating the direction and quantity of tracking shear due to the scanning of a magnetic head are inputted from terminals 4, 5. The error outputs are superposed to the integrated outputs (e), (f) and the superposed outputs are applied to a pair of bimolph plates through amplifiers 2, 3 to deflect the bend of respective bimolph plates and control the deflection of the bimolph plates. Thus, the waveforms of the deflecting voltages are prevented from being made sharp, so that the linearity of a trace can be held.

Abstract: PURPOSE:To perform the specified shift operation correctly and smoothly by forming a drain orifice at the oil pressure chamber of a second hydraulic actuator as well as a cancel oil chamber for centrifugal oil pressure at the back face of a second piston member. CONSTITUTION:The outer diameter part 3a of a first piston member 3 is formed into stepped shape, oil chambers 5a, 7a for a first and a second hydraulic actuators are formed, and a cancel oil chamber 11 for centrifugal oil pressure is disposed. Oil pressure can be thereby fed rapidly even in the first hydraulic actuator 5 as well as drained in the appropriately tuned state. Moreover, a drain orifice is formed at a first piston member 3. The oil that leaks into the oil pressure chamber 7a of the second hydraulic actuator 7 is thereby prevented from being accumulated when the actuator 7 is in the draining state. The centrifugal oil pressure cancelling function of the cancel oil chamber 11 can be therefore positively demonstrated so as to perform the specified upshift and downshift correctly and smoothly.

Abstract: PURPOSE:To reduce a loss of a primary radiator due to spillover of a 1st sub reflection mirror by devising the 1st sub reflection mirror so as to magnify in a plane perpendicular to a center cross section ZX. CONSTITUTION:The orthogonal coordinate system is defined so as to take a mirror axis direction of a main reflection mirror 4 being a component of a reflection mirror system as the Z axis and a center cross section as the ZX plane. Primary radiators 1a, 1b are arranged within the ZX plane, and a reflecting mirror that is a mirror of parabolic face of rotation whose mirror surface is corrected is used for a 1st sub reflecting mirror 5 so that a wave front radius of curvature F1=l2 of a transmission wave made incident in a 2nd sub reflecting mirror 6 within the ZX plane is smaller than a wave front radius of curvature F3=l2 of the transmission wave in a plane perpendicular to the ZX plane. Furthermore, a reflecting mirror whose mirror surface is corrected on an aperture plane of the main reflecting mirror 4 to eliminate aberration is used for the sub reflecting mirror 6. Then an outer shape of the reflecting mirror 5 is formed to be an ellipse whose minor diameter is a cross line with the ZX plane and whose major diameter is a cross line with a plane perpendicular to the ZX plane when viewing from the primary radiators 1a, 1b, an outer shape of the reflecting mirror 6 is nearly a x circle, and an aperture of the reflecting mirror 4 is formed to be a circle. Thus, spillover of the primary radiators due to the reflecting mirror 5 is reduced to suppress the reduction in the gain.
