Title: Device for detecting and controlling track jump
Inventor: KOISHI KENJI
IPC: G11B7/085
Filed: 1982-07-12
Abstract: PURPOSE:To prevent completely mis-recording and double recording caused by an unexpected track jump, by detecting a track jump from a guide track recording information to other guide track out of a track crossing signal, and changing the optical power of a laser light source from the recording state into the non-recording state. CONSTITUTION:When jumping operation is executed, a crossing signal 51 is detected in a tracking error signal similarly the same as a track jump, because an optical spot crosses between pits from a pit of the guide track in the jumping. The cross signal 51 should not be discriminated as track jump. A jumping section pulse 52 and an output of positive/negative comparators 32, 33 are ANDed at an AND gate 56 so as not to discriminate jumping pulses 53, 54 of the jumping section formed with the crossing signal 51 as a track jump signal. The track jump only is detected accurately by using the first leading edge of the pulse of a track jump detecting signal 56 obtained in this way, allowing to reduce the optical power from the recording state into the reproducing state.

Inventor: UEHARA TERUO
IPC: B22C9/24
Filed: 1982-07-13
Abstract: PURPOSE:To reduce charging time and to impove run and the yield of a tank- like casting by charging molten metal directly from the central part of a product cavity and sucking out the air in the cavity through the vents around the cavity. CONSTITUTION:A product cavity 2 of, for example, a boat hull is formed in a casting mold 1, and runners 3 communicating directly with the cavity 2 are formed in the several places at the center of the cavity 2. Vents 4 are formed in several places around the cavity 2. Reserving ladles 7 having stoppers 6 are installed in respective sprues 5, and a vacuum pump is connected to suction hoses 8 through air permeable refractories for stopping to the respective vents 4. The molten metal is beforehand reserved in the ladles 7 in the stage of charging and the molten metal is charged home by removing the stoppers 6 and at the same time by sucking air through the vents 4. As a result, the runners are required to be shorter as compared to bottom charging, and the yield is better. In addition, the run is faster, hence the generation of cold shut or the like is obviated and the good casting free from air inclusion is obtd.

IPC: G03F1/00
Filed: 1983-07-05
Abstract: PURPOSE:To make inspection easy and to enable emission of photoelectron by irradiation of excited light by forming a film over the entire surface of a base plate then forming a pattern of a material having different work function and making the pattern easily visible. CONSTITUTION:A base plate 1'-1 has the 1st film 2' formed over the entire surface thereof and the 2nd film (pattern) 3' which is patterned and formed on the film 2' and has the work function different from the work function of the film 2. Since the pattern 3 is formed on such reticule mask 1', the mask is easily inspectable with a microscope. Excited light is directly irradiated to the pattern 3' superposed on the film 2' of the mask 1' without via the plate 1-1', etc. and therefore the emission efficiency of photoelectron is good and the photoelectron emission surface is faithful to the pattern 3. Photoelectron is emitted from the film 2' and consequently such kind of the reticule mask permits irradiation of the excited light from either the front or rear surface of the plate 1'-1. The reticule mask is made into the type to be used exclusively for reflection or the type to be used for both transmission and reflection by selecting the work functions of the pattern 3' and the film 2'.

Title: Circuit and method for detecting zero cross
Inventor: WATANABE TORU
IPC: H03K5/153
Filed: 1988-05-19
Abstract: PURPOSE:To eliminate an externally connecting capacitor and to decrease the number of externally attached parts by defining an analog voltage value, which is outputted from a D-A converting circuit, as the zero cross value of a detected voltage. CONSTITUTION:With using a register 5 to be used in a successive approximation type A-D converting circuit, a D-A converting circuit 6 and a comparator 7, an inputted alternative current signal is A-D converted to at an arbitrary time. Then, by obtaining a time, in which the alternative current signal is coincident to an analog voltage to D-A convert the digital value, a zero cross point can be obtained. The voltage value of the zero cross point is A-D converted again and compared by the comparator 7 with obtaining the analog voltage to be based on the digital value as reference. Then, the zero cross point can be detected. Thus, it is not necessary to provide an exclusive zero cross detecting circuit and the externally connecting capacitor is also eliminated. Then, the number of the externally attached parts is decreased.

Filed: 1986-05-28
Abstract: PURPOSE:To obtain a stable output, by dividing an output of a D type FF in two to apply one part of the output direct to an AND circuit while the other part thereof is applied to the circuit through a delay circuit. CONSTITUTION:A hold-off signal (a) is applied to a first input terminal 15 while a trigger signal (b) done to a second input terminal 16 and the signals (a) and (b) are applied to a D type FF11. One part of an output signal (c) of the FF11 is applied directly to an AND circuit 13 while the other part thereof is done to the circuit 13 through a delay circuit 12 as signal (d). The circuit 13 operates to produce an output only when the signals (c) and (d) are applied thereto and both go to the H level simultaneously and hence, the circuit 13 will not work by the signal (b) as applied at the time T1. At the time T2, when the signal (b) is applied, the FF11 operates immediately as the signal (a) applied to a terminal 15 is already at the H level and the output of the FF11 shifts to the H level. As the signal (c) is inputted into the circuit 13 directly or through the circuit 12 as signal (d), an output (e) is obtained at an output terminal 17 after a delay time td from the time T2.

IPC: H01L31/04
Filed: 1984-06-16
Abstract: PURPOSE:To obtain the title substrate which can be supplied at a low cost in a mass by a continuous method of high productivity by using a surface-treated steel plate plated with Ni and/or Cr of specific thickness of a cold-rolled steel plate of specific composition. CONSTITUTION:This invention uses a surface-treated steel plate plated with Ni and/or Cr to a thickness of 1mum or more on the original plate made of a cold- rolled steel plate having the composition of 0.1wt% or less C, 1.0wt% or less Si, 2.0wt% or less Mn, 0.05wt% or less Al, and both 0.02wt% or less P and S. The necessary thickness of Ni and/or Cr plating depends on the surface roughness of a cold-rolled plate to be plated. It is necessary to make the plating layer thicker with the increase in the maximum surface roughness Rmax. Ni plating can obtain plating of required thickness efficiently in a short time, whereas this plating is somewhat low in glossiness of the plating surface. Contrarily, Cr plating requires a large current and a long time. Further improvement of the surface- treated steel plate in surface roughness and in glossiness is enabled by skin path rolling. It is preferable to carry out the rolling at a rate of 0.1-5%.
