Title: Rotary head type digital tape recorder
Inventor: FUKAMI TADASHI
IPC: G11B20/18
Filed: 1986-03-04
Abstract: PURPOSE:To prevent generation of abnormal reproduced sound by composing reproduced data of interleave pair mistaken when tracks are reproduced intermittently in the case where interleave of PCM signals is made over two tracks. CONSTITUTION:When making high speed reproducing operation, an interpolating control circuit 49 generates interpolating control signals as shown in the figure C or D responding to comparison output signals of a comparator 47. In the case where the comparison output signal of the comparator 47 indicates that data reproduced by a magnetic head 2A is better in the state of error than data reproduced by a magnetic head 2B, an interpolating control signal shown in the figure C is formed, and the interpolating control signal becomes '1' in the period of PCM signals reproduced by the magnetic head 2B, and the PCM signals are interpolated. On the other hand, when data reproduced by the magnetic head 2B are better in the state of error than reproduced data of the magnetic head 2A, PCM signals reproduced by the magnetic head 2A are interpolated by an interpolating control signal that becomes '1' in the period of PCM signals reproduced by the magnetic head 2A.

Title: Device for casting deformed cast billet
Inventor: MASUDA JOJI
IPC: B22D11/043
Filed: 1992-03-04
Abstract: PURPOSE:To produce a cast billet having good surface and no surface crack even in the deformed cast bullet having complicate shape by arranging a cooling device for directly cooling the cast billet with cooling water independently to the cooling in a mold. CONSTITUTION:Piping is connected with connecting members 16, 17 and cooling water is made to flow in the lower step mold 11b and also flowed in cooling piping 15. Thereafter, when the molten metal is poured into a space surrounded in the inner surface 12 of the mold 11, the molten metal is brought into contact with the inner surface 12 of the mold 11 and cooled to form the solidified shell. The cast billet is successively drawn out downward from a mold 11. Then, the cast billet is directly cooled with cooling water by receiving the injection of the cooling water from the coding water piping 15. In the mold 11, the extremely weak cooling is given, and after the cast billet comes out from the mold 11, the intense cooling is given by the cooling water and the cast billet is perfectly solidified. Therefore, it is prevented that cold shut-like ripple caused by solidification of the cast billet in the mold 11 is formed. As the cast billet coming out from the mold 11 is directly and forcedly cooled with the cooling water, the development of the surface crack can be prevented.

Filed: 1994-03-17
Abstract: PURPOSE:To solve a feeling of physical confusion in synchronizing both exhaust and engine noises attendant upon the opening or closing an exhaust passage by closing the exhaust passage when engine speed goes down, starting the regeneration of a filter, while opening the exhaust passage when the engine speed goes up likewise and finishing the filter regeneration. CONSTITUTION:Exhaust gas discharged out of an internal combustion engine 100 passes through an exhaust passage 101 at a time when both on-off valves 104 and 105 are opened and, after being uniformly distributed at a branch point 101a, it flows into both filter cases 114 and 115 of two branch passages 120 and 130, then those of particulates are removed by both filters 102 and 103. On the other hand, when these on-off valves 104 and 105 are closed, the exhausted particulates are burned by two heaters 108 and 109, whereby both the filters 102 and 103 are regenerated. In this case, at a control unit 150, in the case where engine speed detected by an engine speed sensor 141 is, for example, lowered to some extent under the specified condition, both the on-off valves 104 and 105 are blocked up via two valve drivers 106 and 107, whereby regeneration in both the filters 102 and 103 is started.

Title: Photosensor circuit

IPC: G01D5/347
Filed: 1988-02-29
Abstract: PURPOSE:To obtain the circuit which is stable to temperature variation and has good temperature characteristics by inserting a photodetecting element which responds to the light outputted by a light emitting element in the current flowing-in path of a constant current source, and also connecting a current response switching element. CONSTITUTION:When the end mark of recording paper is not detected, the quantity of reflected light is large and the conduction of the photodetecting element 24 of a photosensor 20 increases; and the current (i) flowing through the photodetecting element 24 increases until i>iC, so as excessive current is generated and flows in as the base current of a transistor (TR) 28. The output of the TR 28 goes down to low level, indicating that the paper does not run short yet. When the end mark is detected, the quantity of the reflected light decreases and the conduction of the photodetecting element 24 becomes small and the current (i) decreases. No excessive current is generated on the current path of the TR 18, which does not turn off and generates a high-level output, thereby detecting the shortage of the paper.

Filed: 1981-03-31
Abstract: PURPOSE:To improve the generation of blurred spots in peripheral frames at the time of multiple frame photographing in a simple constitution by switching a focus voltage in response to the frame position specifying data which specifies the divided regions in a CRT screen. CONSTITUTION:Through a control part 2 for a scintigram pickup signal GI, the frame position specifying signal IP, which specifies the divided region in the screen of the CRT 4, is generated from a signal converting circuit 3 when the multiple pickup mode is specified. A focus voltage corresponding to the frame position is generated from a focus voltage supply circuit 5 such as a PROM. Thus the CRT 4 is controlled. Position signal X and Y and the unblanking signal UNB which indicates luminance from a scintillation camera 1 are converted into display signals and applied on the CRT 4. Therefore the generation of blurred spots in the peripheral frames in the CRT 4 is prevented. Thus the generation of the blurred spots in the peripheral frames in the multiple frame photographing to X ray film is improved by a simple constitution and the quality of the picture is improved.
