Title: Chrominance signal processing circuit
Inventor: NOSE JUNICHI
IPC: H04N9/80
Filed: 1989-01-13
Abstract: PURPOSE:To improve the picture quality of an output chrominance signal by using a first crosstalk removing means when a carrier chrominance signal having many crosstalk components is inputted and using the second crosstalk removing means when a carrier chrominance signal having few crosstalk components is inputted. CONSTITUTION:When the chrominance signal having many crosstalk components is inputted, an automatic phase control loop circuit 40 is composed using a first comb line filter (crosstalk removing means) 30 having short delay time, the crosstalk components are removed, and the frequency of the carrier signal is converted, and when the chrominance signal having few crosstalk components is inputted, the circuit 40 is composed using a second crosstalk removing means 14 having delay time longer than that of the first crosstalk removing means 30 and the deterioration of the vertical image resolution smaller than that of the means 30, and the removing of the crosstalk components and the conversion of the frequency of the carrier signal are executed in the same manner as above. Consequently, the deterioration of the vertical image resolution is decreased when the chrominance signal having few crosstalk components is inputted, the occurrence of the slipping off and the omission of the hue is decreased when the chrominance signal with many crosstalk components is inputted. Thus, the picture quality of the output chrominance signal can be improved.

Title: Manufacture of remelting chilled camshaft
Inventor: FUKUMIZU TOSHIHARU
IPC: C21D1/09
Filed: 1987-01-17
Abstract: PURPOSE:To easily form a surface hardening layer with the desired characteristics over the entire cam width, by controlling the gap between an arc torch and a cam surface according to a cam profile and a cam width at the time of subjecting a cam surface to remelting hardening treatment by means of an arc torch. CONSTITUTION:A camshaft 1 is rotated and, simultaneously, an arc torch 4 is allowed to perform a reciprocating motion at a fixed stroke, and, when a cam base circle part comes to a position under the torch 4, and arc 3 is produced by the impression of electric power to carry out hardening of the cam 2. At this time, when the treatment is started, cam width is large because of coldness of the cam 2, so that the gap T is widened to enlarge the working width of the arc 3 so as to form the prescribed surface hardening layer over the entire cam width. Since the quantity of heat to be absorbed by the cam 2 is reduced and also the width is gradually reduced as the treatment proceeds, the gap T is gradually lessened to the position of a cam nose part of minimal cam width. In this way, the surface hardening layer having the desired characteristics can be formed over the entire cam width.

Title: Soldering method of electronic part
Inventor: HARA SATORU
IPC: H05K3/34
Filed: 1988-01-19
Abstract: PURPOSE:To perform soldering without thermal adverse effects on an electric part, by pushing the electronic part to a board, heating a preliminary solder and/or the board without directly heating the lead of the electronic part, and performing soldering. CONSTITUTION:A lead 2 of a flat package IC, which is an electronic part 1, is placed on a preliminary solder 4, which is provided on a board 3. A heating chip 4 directly heats only the preliminary solder 4 and does not come in contact with the lead 2 directly. A pushing part 5 pushes the electronic part 1 so that the lead 2 is not floated under the state where the preliminary solder 4 is fused. With this state being maintained, heating is finished, and the solder is hardened with a cooling air blower and the like. Thus, the soldering is finished. Since the heating chip 6 does not heat the lead 2 directly, thermal damages of the electronic part 1 become less. Since the electronic part 1 is pushed with the pushing member 5 in soldering, the floating of the lead 2 is prevented.

IPC: H04N5/33
Filed: 1985-01-18
Abstract: PURPOSE:To simplify a structure and to reduce the size and weight of a device by delaying the outputs of plural sensor elements of respective units through mutually different number of stages of charge transfer means and summing the outputs by an adder. CONSTITUTION:Infrared sensor elements 4-1 placed on a substrate 10 are separately amplified (13a-13d) so as to be used as the 1st-4th channels sequentially from above. The 1st-3rd channels are inputted into charge transfer means 14a'-14c' that are delay means respectively. The means 14a'-14c' are weighted by three-, two- and one-stage charge transfer elements BBDs so as to be transferred and delayed in accordance with clock pulses from clock pulse generating means 50. The outputs O1-O3 from the means 14a-14c and the output O4 from the amplifier 13d are summed by the adder 16 to output an added output signal E0 from a terminal 202 to the main body of an infrared video device. In such a manner, the delay at the means 14a'-14c' is executed surely, while liminating LPF which was essential heretofore and only one kind of clock pulses is sufficient resulting in simplified structure and reduction in costs.

Title: Angular error measuring device of rotary polyhedral mirror
Inventor: KITABAYASHI JIYUNICHI
IPC: G01B11/26
Filed: 1982-01-21
Abstract: PURPOSE:To measure an angular error in a short time, by measuring an angle between reflecting surfaces of a rotary polyhedral mirror, by replacing it with the number of reference clock pulses in case when it is rotated at a constant angular velocity. CONSTITUTION:On a rotary polyhedral mirror 1, a synchronization detecting hole 2 for synchronizing with a referenece surface which is selected suitably out of 8 surfaces is provided, a light emitting element 3 and a photodetector 4 which are opposed through the hole 2 are placed, and an output signal (b) from the photodetector 4 is sent as a synchronizing signal, to a processing circuit. On the other hand, a collimator optical system reduces a luminous flux from a light source 5 to a narrow luminous flux by a slit (g) through a half-mirror 6 and a prism 7, and projects it to the rotary mirror 1. When a normal of the reflecting surface of the rotary mirror has become parallel to the projected luminous flux, the reflected ray is reflected by the half-mirror 6 through the same path, and is made incident to a photodetector 10 through a slit 9. When the slit 9 is placed in parallel to the rotary shaft of the rotary mirror 1, only an angle error can be fetched without influenced by the fall of the reflecting surface.

Title: Method and device for measuring liquid by automatic analyzer
Inventor: WAKATAKE KOICHI
IPC: G01N33/48
Filed: 1986-01-20
Abstract: PURPOSE:To obtain a low-cost liquid amount measuring instrument by detecting an air layer which interposes between a sample in a pipet and liquid which extrudes wash water with measurement light. CONSTITUTION:When the sample 50 is sucked up to the pipet P by a suction pump 5, the wash water W, air (a), and the sample 50 are contained in the pipet P in order as the sample 50 rises. Then, the pipet P is irradiated with scanning light from a light emitting element 1. The air (a) hardly attenuates the quantity of light, so a voltage signal led out of a photodetecting element 2 rises and is inputted to a control part 4 through an A/D converter 3 and when the air (a) passes through the element 1, the timer of the control part 4 begins to count the time. The counted time of the timer is made to correspond to the time of suction of a amount of liquid necessary for analytic processing and a CPU 8 is programmed previously so as to control the driving of the pump 5. When the pump 5 is stopped after the timer clocks a necessary time, a necessary amount of sample 50 is sucked in the pipet P and therefore measured without using any potentiometer, so the cost is reduced.
