Title: Coherent signal processor
Inventor: SASAYAMA KOJI
IPC: H04B10/54
Filed: 1989-02-14
Abstract: PURPOSE:To couple a light signal coherently and to utilize the speediness and band broadness of an optical waveguide by combining variable branching devices and phase shifters and performing optional weighting. CONSTITUTION:The variable branching devices S0, S1... Sn-1 distribute light signals which have electric field amplitudes at an optional branch ratio to respective taps and the branch ratio shows the absolute value of the weighing coefficient of each tap. The light signals which are distributed to the respective taps are phase-shifted optionally by the phase shifters P0, P1... Pn-1 and added after being multiplied not only non-negative real number coefficients, but also by optional weighting coefficients including complex numbers. Consequently, the signal processor which enables coherent coupling by using the optical waveguide as a delay line is obtained.

Title: Density gradation equalizer for video printer
Inventor: ITOU NOBUYUKI
IPC: H04N1/407
Filed: 1990-02-14
Abstract: PURPOSE:To adjust the gradation of the density of a print picture locally by supplying a current to a printer based on the time adding/subtracting data of correction application time to/from a reference application time. CONSTITUTION:A density gradation signal conversion section 4 judges the gradation of a picture data read out of a memory 3 and outputs data of each gradation for 64 times at maximum depending on the gradation, e.g. in the case of the 64 gradation printer. A control section 9 outputs a strobe signal every time the write of data is finished to a line memory of a printer 5 and the length of the time of the signal depends on the data of a strobe time outputted from an equalizer 8 based on the judgement of the gradation by the conversion section 4. That is, the 64 gradation is divided into 5 gradation blocks (lightest), (light), (intermediate), (dark), and (darkest), and a lever 11 to adjust each density is provided, a correction strobe time is selected for each gradation by the operation of the lever to add/subtract to/from a reference strobe time from a storage section 7 and the resulting data is outputted.

Title: Power transmitter for motorcycle
Inventor: NAKAMICHI MASAKAZU
IPC: B60K17/04
Filed: 1982-03-03
Abstract: PURPOSE:To prevent the locking of rear wheel due to the brake seizure of the engine during running by using a lap spring clutch to interrupt the transmission of revolution from a crankshaft to a kick shaft in the power transmitter of a motorcycle capable of starting up its engine by pushing manually. CONSTITUTION:When the revolution of a crackshaft 108 becomes impossible due to the seizure of a piston 118, etc., during running of vehicle, the rotation of a gear 86 engaging with a gear 110 is stopped. On the other hand, a rear wheel hub 82 is turned by means of inertia even after the locking of the crankshaft 108, and the revolution is transmitted to a cylinder 90 through a chain 128, a transmission shaft 38, a change gear 81, and an intermediate shaft 64. When the cylinder 90 turns in relation to the gear 86 stopped, the lap spring clutch 92 is contracted in the diameter and the revolution is ready to be transmitted by the connection of the cylinder 90 with a boss 88. However, since the revolution suppression force of the crankshaft 108 is very great, the clutch 92 is slipped and the cylinder 90 is also run idle. Thus, the rear wheel hub 82 is locked and therefore, the tumbling of vehicle running can be prevented.

By this method, a protrusion is properly formed by the non-conc. magnetic ink and stable image quality is obtained.

Title: Focusing adjusting apparatus in mtf measuring machine
Inventor: SAGANE MITSUKI
IPC: G01M11/02
Filed: 1983-03-02
Abstract: PURPOSE:To automate lens focusing so as to make the focusing quick and to decrease costs, by performing the focusing at plurality of stages, and narrowing the step of each stage with MTF being observed. CONSTITUTION:A control-signal generating circuit 18 divides the entire stroke range into (n) parts by the adjustment at the first stage. MTF values are computed by a Fourier operating circuit by (n) steps. A lens 3 and a chart 5 are moved by motors 9 and 14 at a speed ratio of 1:(1+m)/m, where (m) is a magnification. A step position (k), where the MTF value becomes the maximum within this range of movement, is memorized. At the adjustment at the second stage, the step is further narrowed, and the lens and the chart are moved by (m) steps. At the adjustment at the third stage, they are moved by l steps at the final precision. Thus the highly accurate focusing device is finally implemented within the precision range of a ball screw.

Title: Method for working microrecessed part of optical waveguide and working device therefor
Inventor: SATO SHIRO
IPC: G02B6/13
Filed: 1994-03-04
Abstract: PURPOSE:To obviate the generation of microcracks in a worked hole part by press- fitting a presser heated at its front end part of a circular conical shape into the core part of a waveguide exposed at the end of a substrate, thereby transferring the shape at the front end part of the presser to form a recessed part. CONSTITUTION:The front end of the presser 11 is heated and the presser 11 is gradually lowered by placing a suitable weight on a weight base 14. The position of the presser 11 is known by a microdisplacement meter 20 when the presser 11 comes into contact with an optical waveguide substrate 70. Further, the presser 11 is press-fitted into the core part by the weight of the weight. The state is maintained for a certain period of time. The microrecessed part to which the shape of the presser 11 transferred, is thereafter formed by removing the presser 11. The shape of the presser 11 is determined by the shape of the front end of an optical fiber. A projecting part of a circular conical shape is easily formed by an etching method and, therefore, the use of the presser having the circular conical shape is recommended. The recessed part shape is formed in the state that the core part exhibits a ductility behavior if the presser is formed in such a manner and, therefore, the generation of the microcrack is prevented.

Abstract: PURPOSE:To most suitably change the reproducing timing by setting the timing of a changeover pulse signal for a reproducing head based on a discrepant amt. between a rotary position signal of a rotary head drum and the reproducing timing of a reference signal recorded previously. CONSTITUTION:A detecting pulse signal is outputted by a synchronizing signal detector 9 with timing for obtaining a synchronizing signal.

Then, a reference timing signal is supplied from a ROM 15 to the comparator 14, and a difference between the timing detecting signal and the reference timing signal is detected by the comparator 14, and then an error signal corresponding to this discrepant amt. is outputted. A head changeover pulse signal is delayed by a variable phase delayer 12 by timing presenting by the error signal, and changeover timing for a regenerative signal by a changeover switch 7 is delayed by the timing presented by the error signal.
