Title: Manufacture of shadow mask for color image receiving tube
Inventor: KIHARA HISATO
IPC: H01J9/14
Filed: 1990-06-20
Abstract: PURPOSE:To enhance the blackening processing efficiency of a blackening processing furnace by placing a plurality of foamed masks one over another in a caging having vents distributed evenly over the peripheries, putting them in oxidative gas or water vapor atmosphere, and heating them as the blackening process. CONSTITUTION:If foamed masks are put one over another simply in a caging consisting merely of frames not surrounding the whole peripheries with meshing and subjected to a blackening process, the blackened films over the foamed masks at the top and bottom become much thicker than those on the foamed masks laid in the middle to provide unserviceability. If the blackening processing is made, on the other hand, by the use of a caging 22 with the whole peripheries surrounded by meshing 21, all masks can be provided with equal blackening. This is because the meshing 21 having vents distributed uniformly over the whole peripheries of the caging shuts off the oxidative gas or water vapor atmosphere, which relieves the action on the top and bottom foamed masks 23 to ensure that all foamed masks 23 receive uniform actions.

Title: Head switching signal generation circuit of vtr
Inventor: NAKAMURA TADAHIKO
IPC: H04N5/7826
Filed: 1978-12-29
Abstract: PURPOSE:To cause the switching point of head switching to enter a prescribed range by obtaining a head switching signal on a basis of the residual error of phase servo obtained from a phase detection counter. CONSTITUTION:Pulse signal PGH from a pulse generator is delayed by a prescribed time by monostable multivibrator 29. Output PGHDL of monostable multivibrator 29 follows the error of servo phase. However, reset signal VDL of FF30 is independent of the error of phase servo. Consequently, phase detection counter 35 counts clock pulses TF6 256 or less or more for phase delay or advance. Then, immediately before further 1/2 rotation of the head column, FF45 is set by the output pulse of decoder 27, and counter 35 counts pulses TF6 again. Then, in case of phase error, the counter counts pulses 256 or more or less by lack or surplus components of the preceding count. As a result, head switching signal DFSW is changed according to phase error.

Title: Automatic weighing/discriminating method for transported article
Inventor: TOMITA SHIGERU
IPC: G01G11/00
Filed: 1979-12-14
Abstract: PURPOSE: To ensure an easy and accurate weighing/discrimination for the transported object, by deciding both the allowable upper and lower limits to discriminate the object nondefective and defective in case it is within and outside the above-mentioned range of limit.  
     CONSTITUTION: The weighing conveyor 2 is provided at the middle of carriers 1 and 1', and the weight is measured for the object transported on the conveyor 2 with the load cell and by the voltage. This voltage is digitized through an A/D converter to be converted into the binary number. This binary number is introduced to each of a pair of comparators S1 and S2 from A, and the binary number of the allowable upper limit value is introduced to the S1 from B. At the same time, the binary number of the allowable lower limit value is introduced to the S2 from B'. Accordingly, the output is delivered from the OR circuit C in case the object is outside the upper and lower limits, thus operating the alarm mechanism or the eliminating mechanism. In such way, the weighing/descrimination can be done in an easy and accurate way for an object transported.

Title: Driver circuit
Inventor: TOOMASU DEIRU FURETSUCHIYAA
IPC: H03K19/0175
Filed: 1991-07-03
Abstract: PURPOSE: To provide a driver circuit in which an operation can be attained at a high speed without correspondingly increasing a noise. CONSTITUTION: High and low impedance drive means 26 and 28 are operated in parallel so that desired output transition can be generated in a driver circuit. An adaptive controlling means 32 turns off the low impedance drive means during the output transition in response to the threshold value of an output signal VO. The low initial output impedance of the driver circuit quickly charges a line capacitance CL, and the further high output impedance of the driver circuit is closely matched with the input impedance ZL of a load circuit toward the end of the output transition. Thus, the high impedance attenuates ringing, and a power source line noise related with the high speed driver circuit so far can be reduced.

Abstract: PURPOSE:To impart desired dimensional accuracy to the electric welded tube by the machining and pressing to be executed after the execution of a normalizing treatment by subjecting the electric welded tube having a specific compsn. to the normalizing treatment. CONSTITUTION:The electric welded tube having the steel compsn. consisting, by weight %, of <=0.25% C, <=1.60% Mn, 0.010 to 0.050% Nb and the balance Fe is subjected to the normalizing treatment. This normalizing is executed for the purposes of the uniformization of the structure, the relief of internal stress, softening and uniformization. A method of heating the tube to the temp. higher by about 40 to 60 deg.C than the AC3 point then cooling in the atmosphere is exemplified as the conditions for the above-mentioned normalizing and is not particularly limited to this method. The hardness near a weld zone is lowered by this normalizing and the weld zone having approximately the same hardness as the hardness of general parts exclusive of the weld zone is thus obtd. The machining, etc., to be executed after this treatment becomes therefore, extremely easy and the dimensional accuracy of the inside diameter of the electric welded tube is stably assured. The electric welded tube adequate to the tube for a hydraulic cylinder, etc., is obtd.
