Title: Working and treatment of ic lead frame
Inventor: KENMOCHI GOUJI
IPC: H01L21/56
Filed: 1986-06-25
Abstract: PURPOSE:To prevent trouble in subsequent carrying and working treatment by holding the nonuse section of the periphery of an IC lead frame in upper and lower sections by a holder. CONSTITUTION:Since the nonuse section 25 of the periphery is held in upper and lower sections by a holder 4 in an IC lead frame 2, the lead frame 2 is difficult to be distorted even when executing molding treatment, etc., and it is held by the holder 4 even when it is distorted, thus resulting in no trouble in subsequent working treatment and carrying. Since an island 8 and use sections 23 corresponding to pin 14 sections are brought to an exposed state, various working treatment can be executed freely. The IC lead frame 2 is removed from the holder 4 after working treatment, and only the holder 4 is employed repeatedly for holding and carrying the IC lead frame 2 again, thus resulting in advantage in cost.

Title: Constant voltage generating circuit
Inventor: NISHITOBA SHIGEO
IPC: G05F3/30
Filed: 1983-08-11
Abstract: PURPOSE:To obtain plural constant voltage output terminals by one reference voltage circuit by using in common the reference voltage circuit so as to generate plural output voltages and applying its output voltage to the reference voltage circuit via a switching transistor (TR) as a voltage source. CONSTITUTION:An equal normal voltage is outputted from an output terminal 5 or 35 at normal operation, a base potential to TRs 9, 10 is made equal, the TRs 9, 10 are both conductive and a bias current to the reference voltage circuit 1 is applied. If a constant voltage to be produced at the output terminal 5 is zero V because of the operation of a protection circuit 6 due to an abnormal state such as short-circuit of load, the base voltage of the TR9 is zero V and the TR9 is cut off. On the other hand, since a normal constant voltage is generated at the output terminal 35, the TR10 is in operating state, and an output terminal 32 is in normal state. Conversely, even if a protection circuit 31 is operated because of the faulty terminal 35, since the TR9 is in operating state and the circuit 1 is biased normally, the output terminal 5 is in normal state.

Title: Measuring method for flying particulate and finely divided particle and controlling method for plasma spray
Inventor: SAKUTA TADAHIRO
IPC: G01N21/17
Filed: 1991-06-19
Abstract: PURPOSE:To enable particle diameter, temperature, speed, etc., to be measured simultaneously for a single particle by applying light to a flying and finely divided particle and then analyzing a wave-height characteristic and a time width of a light-emitting pulse waveform of this finely divided particle. CONSTITUTION:A particle passing through an observation point A within plasma allows He-Ne laser B scattering light and its own continuous radiation light to be discharged toward an incidence observation window slit S. The slit S has a height H and a width W. A spectrometer C allows these lights to be decomposed into three portions, namely wavelengths lambda1 and lambda2 are continuous light components from a particle itself and lambda3 is a laser scattering light. These light intensities can be changed into an electrical signal by a photoelectron amplification tube D2, enter a digitizer E, and are stored as a digital signal where analog signal of CH 1 and CH 2 corresponding to the wavelenghs lambda1 and lambda2 can be analyzed. A signal corresponding to the wavelength lambda3 is connected to a trigger terminal and functions so that only a particle entering a point A is properly selected. Record data are sent to a computer F, waveforms of CH 1 and CH 2 are automatically analyzed, and a particle diameter, etc., of a single particle are output.

Title: Unevenly-patterned hot-dipped steel sheet of high contrast and its manufacture
Inventor: SHIYOUJI TAKESHI
IPC: C23C2/40
Filed: 1979-11-16
Abstract: PURPOSE:To manufacture the titled steel sheet with superior corrosion resistance, suitability to coating and rigidity by hot dipping an unevenly-patterned cold-rolled steel sheet and optionally carrying out alloying treatment at once followed by leveling and surface polishing. CONSTITUTION:Unevenly-patterned cold-rolled steel sheet 1 is uniformly hot dipped by applying a hot dipping thickness adjusting method by gas spraying. Since hot dipped layer 2 has a uniform thickness the uneven pattern remains almost similarly after the hot dipping. Alloying treatment may be carried out immediately after the hot dipping. Sheet 1 is then leveled to correct the flatness, and protrusions 4 alone of sheet 1 are uniformly polished. Sinse recesses 3 are not polished at this time, they have no luster. Accordingly, the contrast is further raised, and an unevenly-patterned hot-dipped steel sheet with superior appearance is obtd.

Title: Transfer method for mask pattern
Inventor: KATOU TAKAAKI
IPC: G03F1/00
Filed: 1981-09-19
Abstract: PURPOSE:To correct a defective mask, by using masks where a prescribed pattern and a pattern, which is obtained by mirror conversion of this pattern, are formed on glass plates individually and arranging both masks so that respective patterns face to each other and transferring them. CONSTITUTION:In case that a mask 7 which has a Cr pattern 3 having a pinhole 3 or the like is corrected, a Cr mask 8 is produced where a Cr pattern 1' having a shape obtained by mirror conversion of the Cr pattern 1 of this mask 7 is formed on a glass plate 2'. Masks 7 and 8 are so arranged that surfaces of both Cr patterns 1 and 1' face to each other closely or at a proper interval, and patterns are transfered. Thus, there is a very little probability that a defect 3' is formed in the same position as the defect 3 of the pattern 1 on the Cr pattern 1'. Consequently, defects of patterns 1 and 1' are compensated and hidden by each other to make an accurate transfer possible.
