Title: Decoder for decoding pal color signal
Inventor: DEIBUITSUDO ROBINSON
IPC: H04N9/64
Filed: 1989-08-14
Abstract: PURPOSE: To correct the picture disturbed by a luminance output and a color output to satisfactorily decode a PAL synthesized signal by sending the output of a comb-shaped defect detection circuit to the control input of a filter circuit through a delay circuit by an adaptive circuit. CONSTITUTION: A filter circuit 12 separates a received PAL synthesized signal to a luminance signal and a color signal. A comb-shaped defect detection circuit 14 generates a comb-shaped signal in response to detection of a preselection error signal in this synthesized signal. Since a control signal proportional to the magnitude of the error signal is applied to a filter circuit 12 which prevents the preselection error signal from passing through the filter circuit 12, an adaptive circuit 84 sends the output of the circuit 14 to a control input 24 of the filter circuit 12. Then, the adaptive circuit 84 applies delay of one picture frame to the comb-shaped error signal through a delay circuit 20. Thus, the PAL color signal is effective decoded.

Title: Toner for electrophotography
Inventor: KATAGIRI YOSHIMICHI
IPC: G03G9/087
Filed: 1985-09-20
Abstract: PURPOSE:To improve the fluidity of a toner without affecting the electrostatic chargeability thereof by using the toner which is held stuck with polymethylsilsesquioxane resin powder. CONSTITUTION:The heating temp. for the toner is required to be the temp. at which the scorch and property deterioration of paper do not arise. A binder resin of a low softening temp. is used for this purpose. The resin having the low softening temp. condenses by easily receiving the influence of heat, moisture, pressure, etc. Blocking and caking are inevitably liable to arise with such resin. This toner is thereupon provided with the fluidity by interposing the pulverous polymethylsilsesquioxane powder having >=500 deg.C softening temp. and several mum grain size between the toner particles. Since the pulverous polymethylsilsesquioxane particles are used to the extent of sprinkling the same on the toner, the use of said particles at 0.01-3wt% of the toner weight suffices. These pulverous particles are electrostatically stuck to the toner. The electrostatic chargeability is not affected at all even if such stuck material exists in the toner.

IPC: G01B11/06
Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To provide a film thickness measuring device wherein shorter measurement time and smaller and lower cost device is realized. SOLUTION: A light L1 from a light source part 2 is projected on a substrate 91 through a filter 43 which allows the light of a specific wave length to pass, and the reflected light L2 from the substrate 91 is photo-detected with a photo- detecting means 5 comprising multiple photo-detecting elements arrayed in 2-dimension. Kind of the filter 43 is changed by using a changing means 4, so that lights of different wavelengths are projected in order on the substrate 91. Thereby, the 2-dimension space distribution information on the light quantity of reflected light when the lights of multiple wavelengths are projected in order on the substrate is sent to a processing part 6 sequentially, and based on the information, the film thickness at the area of the substrate 91 where the light L1 is poured is collectively obtained.  As a result, such means as moving of the substrate 91 not required, shorter measurement time and smaller and lower- cost device is attained.

Title: Serial data transmitter/receiver
Inventor: MOTOYOSHI KATSUNORI
IPC: H04L13/10
Filed: 1992-07-13
Abstract: PURPOSE:To provide a serial data transmitter/receiver which has a simple constitution of a self-stopping counter and can omit the bit shift operation to set the head of a bit train at the head transmission bit of the data head byte. CONSTITUTION:A self-stopping counter is constructed which carries out counting from -N up to zero by setting the complement of '2' of the all transmission bit number N as the initial count value 32 of a counter 18. The change of the most significant bit of the count value output, i.e., the change of the fall of a code bit is directly used as a count stop signal. Therefore the dividing unit of the parallel/serial conversion is defined every 8 bits starting at the final transmission bit of the final byte. Thus the transmission data are sent at an optional bit position of the head byte. Then a selector 12 defines the count value output of the counter 18 as the selection signals S0, S1 and S2 and selects one of those transmission data signal lines which are outputted from a FIFO memory 10 to send the serial data 1 in series and in sequence.

Title: Method for coating small-diameter drill made of high-speed steel with hard ceramics film
Inventor: TANAKA YUSUKE
IPC: C23C14/32
Filed: 1988-08-22
Abstract: PURPOSE:To prevent deterioration in hardness in a base material by carrying out ion bombard cleaning by means of gaseous glow discharge, performing arc metallic ion plating at a special impressed voltage, and forming an intermediate layer of Ti metal to a specific thickness. CONSTITUTION:In a primary stage, ion bombard cleaning is carried out by means of gaseous glow discharge to clean the surface of a base material, and, in a secondary stage, arc metallic ion plating is performed at an impressed voltage of -20 to -400V by using Ti ions to form an intermediate layer of Ti metal to 0.05-0.2mum thickness, and further, Ti metal-containing reactive ion plating is carried out to form a hard ceramics film in a third stage. Since the impressed voltage is low, a temp. rise in the base material up to >=500 deg.C can be prevented. When the thickness of the intermediate layer is small, adhesive strength of the hard surface film cannot be improved, and, when it is large, the occurrence of peeling is brought about in the intermediate layer. By this method, the hard ceramics film can be vapor-deposited without deteriorating the hardness of the base material.
