Title: Driving device for semiconductor laser
Inventor: ASATANI YASUMASA
IPC: H01S5/042
Filed: 1993-04-16
Abstract: PURPOSE:To shorten a time required for setting a current of a constant current circuit in a semiconductor laser drive device for selectively adding a current from a plurality of constant current circuits according to optical strength modulation signals to be a drive current of a laser diode. CONSTITUTION:Initially, when a circuit for setting a current is denoted as a constant current circuit 8, in order to set a constant current of the constant current circuit, a digital input value into a DA converter 14 is successively increased in the same manner as the prior art to reach a desired current. In order to set a constant current of another constant current circuit 5, starting from the already set constant current, a current is changed to reach a desired current. In the case, from upper bits of digital inputs given to a DA converter 13, a value is successively decided in trial and error manner. Thus, the number of times of trial and error becomes the same number of times as the bit number of digital inputs, say the small number of times. As compared with setting by successively changing a digital value, a time required for setting becomes shorter.

Title: Counter circuit
Inventor: KONNO HARUTSUGU
IPC: H03K23/86
Filed: 1988-05-13
Abstract: PURPOSE:To increase number of bits of a counter without decreasing the operating frequency by detecting overflow for each block and executing reload of a data. CONSTITUTION:A critical path exists in a low-order block and has a maximum of 12 stages, and a load capacity to a reload signal RLDA is for four gates comprising flip-flops F1, F2 and two gates and it is constant independently of number of bits of a high-order block. Moreover, the critical path in the high-order block is ten stages and the load capacity is for five gates, then the reloading is slow, but since reloading of the high-order block has only to be executed while overflow takes place in the low-order block, no high speed operation is required toward the low-order block. Thus, the reload counter whose operating frequency is not lowered is obtained even if number of bits of the counter 1 is increased.

Title: Lithography
Inventor: YAMADA KOICHI
IPC: G03F7/11
Filed: 1989-05-08
Abstract: PURPOSE:To lessen side etching and prevent occurrences of characteristic failure in a semiconductor element and the like by raising the temperature of an object as 120-140 deg.C when hexamethyldisilane(HMDS) is made to come into contact with the surface of the object in a state of a vapor phase. CONSTITUTION:Before a resist film 13 is deposited on the surface of an object 11 on which a pattern is formed, the temperature of the object is raised at a temperature as 120-140 deg.C when HMDS is made to come into contact with the surface of the object in a state of a vapor phase. Then, if the temperature of object 11 of patterning is raised, the effect of HMDS as a coupling reagent becomes strong and such a state of HMDS improves adhesion between the resist film 13 and the object 11 of patterning and lessens side etching (d). Element dimensions which are obtained in the case of a design are thus reproduced faithfully and then this process contrives fineness of each element or decrease in characteristic failure of the element.
