Title: Production apparatus for semiconductor device
Inventor: YAMADA MAMORU
IPC: G03F7/16
Filed: 1986-04-23
Abstract: PURPOSE:To smooth the flow of an exhaust flow in a partition wall, and to protect the back of a substrate by boring an exhaust nozzle for air to the side surface of a spin chuck in an applicator applying a photo-resist to the substrate, turning the spin chuck, to which the semiconductor substrate is sucked. CONSTITUTION:Exhaust nozzles 3 for air are bored to the side surface of a spin chuck 2 in a line manner. Since air is ejected from the exhaust nozzles 3 in the side surface of the spin chuck 2 when a photo resist is spin-coated to a semiconductor substrate 1, a strong air flow is generated up to an exhaust port 5 from the exhaust nozzle sections, thus smoothing an exhaust flow. Consequently, the scattered photo resist is discharged sufficiently, and the quantity of the photo-resist adhering on the wall surface of a partition wall 4 is reduced, thus preventing the spring-back of the photo-resist. An air flow layer is formed on the back of the substrate, and functions as protection to the back of the substrate when the photo-resist is sprung back, thus obviating re-adhesion thereof.

Title: Transition detection circuit
Inventor: TAGO AKIHIKO
IPC: H03K5/04
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a transition detection circuit which is effective to increase the access speed by the reduction of capacitance of an input circuit and also to improve the noise characteristics by detecting the rise or fall of an input signal and expanding the pulse width of an output signal. SOLUTION: When an input terminal T1 falls, an output pulse is generated by a rise pulse detection circuit of a circuit block B2 and a pulse expansion circuit of the block B2 expands the output pulse. When the terminal T1 rises, an output pulse is generated by a rise pulse detection circuit of a circuit block B1 and a pulse expansion circuit of the block B1 expands the output pulse. The output waveforms of both blocks B1 and B2 are logically synthesized to obtain an output waveform of a transition circuit. Thereby the output pulse of a transition detection circuit having a sufficient reset time can be generated even with the pulse width that is generated by the noise of an input terminal that does not satisfy the reset time. Furthermore, the load capacitance of an input circuit can be optimized and accordingly the access speed is increased.

IPC: G09G5/36
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To properly, simultaneously and visibly output the distributions against the value included in all ranges despite a very large range of the desired value to be displayed. SOLUTION: When this device displays plural vector data as shown by the arrows, the maximum value Vmax is decided among these vector data. Then the the largest length set by the above arrows is divided by the value Vmax, so that a conversion scale factor (h) is set (S34). The arrow length corresponding to each of vector data is decided as h × log (α × vector value) based on an auxiliary coefficient α and the common logarithm (S35), and an arrow is drawn in the direction of the vector data (S36). These processes are applied to all vector data (S37).

Title: Manufacture of contact material for gold plating
Inventor: HAYAKAWA NAOYUKI
IPC: H01B13/00
Filed: 1988-04-19
Abstract: PURPOSE:To obtain an electric contact material with outstanding abrasion resistance quality by applying the plating of Au or an Au alloy with a pulse wave in an appropriate range. CONSTITUTION:Au or an Au alloy is plated with a pulse wave on a base material or base plating layer made of Cu, Fe or their alloy. When the switch-on time TON=0.1-10msec, the switch-off time TOFF=0.1-100msec and the duty cycle theta=0.01-0.5 (theta=TON/(TON+TOFF)) are applied to the pulse wave, the adhesive quality of a plating film of Au or an Au alloy is increased and its abrasion resistance quality is improved. Especially it is desirable to use the pulse wave of the switch-on time Ton=1msec, the switch-off time TOFF-19msec and the duty cycle theta=0.05. This process makes it possible to obtain a contact material for gold plating capable of attaining a contact resistance value stable for a long time.
