Title: Reproducing device
Inventor: TANAKA MASATO
IPC: G11B5/09
Filed: 1989-09-19
Abstract: PURPOSE:To simplify the constitution of a device by providing an automatic equalization function for extracting the change of the influence degree of the characteristic parameter of an equalizer in odd and even traces. CONSTITUTION:A digital signal from an input terminal 21 is weighted by the characteristic parameter C1 from a characteristic parameter control part in a multiplier 24. A signal from the terminal 21 through a delay circuit 22 is weighted by the characteristic parameter C2 in a multiplier 25, and a signal through the serial circuit of delay circuits 22 and 23 is weighted by the characteristic parameter C3 in a multiplier 26. The outputs from the multipliers 24, 25 and 26 are added in an adder 27 and outputted from a signal output terminal 28 as the digital signal to which filtering processing is performed. Thus, the structure of an entire system is simplified and the enlargement of form and the increase of weight, cost and power consumption are prevented.

Title: Method for peeling resist pattern
Inventor: MIZUSHIMA AKIKO
IPC: H01L21/30
Filed: 1988-09-28
Abstract: PURPOSE:To sufficiently peel even the resist patterns which are extremely changed in properties as a result of processes such as dry etching and ion implantation and to avoid giving damages to wiring layers under the resist patterns by irradiating excimer laser light in a vacuum. CONSTITUTION:The resist surface is irradiated with excimer laser light in a vacuum. The irradiation of the excimer laser light to the resist patterns leads to a high degree of crosslinking and change in properties by the dry etching and ion implantation. Even the resist patterns which are not sufficiently peeled by the wet peeling method can be completely decomposed and removed by an abrasion effect in this way. Resticking of the once decomposed resist patterns to a substrate is prevented and the effect of completely removing the same is obtd. under a high vacuum condition. The damages to the substrate are eliminated.

Title: Distilling method for petroleum-based dry-cleaning solvent
Inventor: KUROKI KIYONORI
IPC: B01D3/10
Filed: 1990-09-13
Abstract: PURPOSE:To efficiently perform distillation until the end point while surely preventing bumping phenomena by rapidly distillation route until the initial boiling point, namely a boiling state and thereafter slowly decompressing it. CONSTITUTION:A solvent dirtied in a washing stage is sent to a distiller 11 and heated therein. The gasified solvent is condensed by a condenser 12 for distillation. This obtained clean solvent is stored in a clean oil tank 14 through a moisture separator 13. In this case, a distillation route incorporating the distiller 11, the condenser 12 for distillation, the moisture separator 13 and the clean oil tank 14 is rapidly decompressed through a large-flow rate exhaust conduit 511 by a vacuum pump 50 until reaching the initial boiling point of the solvent. This exhaust conduit 511 is changed over to a small-flow rate exhaust conduit 512. The said distillation route is slowly decompressed until reaching the end point. As a result, distillation of the petroleum-based dry- cleaning solvent is continuously and efficient performed while surely preventing bumping phenomena.

Title: Semiconductor laser device
Inventor: YAGI TETSUYA
IPC: H01S5/00
Filed: 1987-09-24
Abstract: PURPOSE:To reduce the threshold current, and improve the light emitting effi ciency, by thinning the thickness of a second clad layer except a stripe type ridge part. CONSTITUTION:By thinning the thickness of a region except a stripe type ridge part of a second clad layer 14, in order to enable the reduction of the current component which flows in regions except an active region and becomes ineffec tive, a first current blocking layer 16, whose band gap is wider than a second current blocking layer 17, is inserted between a second clad layer 14 and the second current blocking layer 17. That is, the current is constricted by the first and the second current blocking layers 16 and 17, and the absorption to constitute a loss guide type mechanism is attained only by a second current blocking layer 17. Therefore, even if the thickness of a region except a stripe type ridge part 15 of the second clad layer 14 is made thick, the distance be tween a laser light existing region 21 and the second current blocking layer 17 does not become small.

Title: Semiconductor light-emitting device
Inventor: TAKAHASHI SHOGO
IPC: H01L33/44
Filed: 1986-10-11
Abstract: PURPOSE:To increase the speed of response without lowering the optical output by making the hole concentration of both side sections having low current density in a light-emitting region higher than in other sections. CONSTITUTION:An n-type clad layer 2, an active layer 3, a p-type clad layer 4, a contact layer 5, an insulating film 6 with an opening, an electrode 7 connected to the contact layer 5 through the opening, and a p-type impurity diffusion region 9 formed extending over the active layer 3, the P-type clad layer 4 and the contact layer 5 on both sides of a region just under said opening are shaped onto a semiconductor substrate 1. The distribution of current density J in a light-emitting region in the active layer 3 is lowered in both side sections separate from the center of the light-emitting region, but the p-type impurity is diffused to the sections and hole concentration is increased, thus preventing the decrease in the speed of response. The luminous power conversion efficiency of both side sections is reduced, but the luminous intensity of both side sections is minimized relatively and the rate to a total optical output is originally small, thus hardly lowering the total optical output.

Filed: 1984-11-20
Abstract: PURPOSE:To prevent an electronic apparatus from misoperation or misswitching by forming a normal key, a function key and an operation mode switching key and discriminating a key combination input to switch the operation mode. CONSTITUTION:When the function key (CONT) 21 is depressed, a code C-C is generated, decoded by a decoder part 16 and converted into a decode level CC to output the decode level CC. The decode level CC is sent to a keyboard part 2 to turn on a display unit 22. The decode level CC is stored in the decoder part 16 until the succeeding prescribed combination code is received. When the operator depresses an '0' key 23, the decoder part 16 decodes a generated code C-O, finds out the AND between the decoded value and the already stored decode level CC and outputs the AND as a decode level CC.O. Consequently, an FF 15 is inverted and the operation mode is switched from an off-line typewriter mode to a remote printer mode.
