Title: Formation of multilayer resist
Inventor: SHIBATA SATORU
IPC: H01L21/302
Filed: 1986-12-19
Abstract: PURPOSE:To prevent resist layers from being mixed with each other and to realize the coating process of multilayers by a method wherein, after the surface of a first resist layer has been processed by a plasma, a regenerated layer is composed of a fluorocarbon material. CONSTITUTION:A first resist layer 12 is coated on a semiconductor substrate 11. After this assembly has been pre-backed at about 90 deg.C, it is illuminated by a plasma 13 in a gaseous atmosphere of CF4, CHF3 or the like, and a regenerated layer 14 is formed on the surface of the first resist layer 12. PMMA suitable for a minute pattern process is applied as a second resist layer 15 so as to form a two-layer resist structure. An opening is made at the second resist layer 15 by an ordinary alignment method so as to make a resist hole 16; the first resist layer 12 is developed by using an AZ developing solution. By this method, a two-layer resist pattern is completed. As a result, it is possible to prevent resist the layers from being mixed with each other and to realize the coating process of multilayers.

Title: Heating device
Inventor: TAKASHIMA SHOJI
IPC: H05B3/78
Filed: 1988-11-28
Abstract: PURPOSE:To always operate an ascending/descending stick smoothly by providing the stick to pass a pipe, which is fix to the wall of heating, through freely movably and to execute the ascending and descending of a loading body to the liquid surface of a liquid tank and the heater of the pipe. CONSTITUTION:When microwave fry cooking is executed, main switches 31, 32 and 33 are turned on and a changeover switch 34 is changed over to a cooling side. At such a time, a thermostat 18 detects the temperature of oil and are turned-on and off and relay switches 36 and 37 are turned on and off. Then, electrification to heaters 19 and 20 is controlled and the temperature of the oil is maintained at a prescribed temperature. Continuously, when a motor 29 is electrified, an ascending/descending stick 23 is moved upward and a basket 21 is raised up. Afterwards, when foods are put into the basket 21 and the electrification to the motor 29 is stopped, the basket 21 falls down by dead weight and goes into the oil and the microwave fry cooking of the foods is executed. Here, as long as the switches 31, 32 and 33 are turned on, a pipe heater 24 is electrified and a pipe 22 and the ascending/descending stick 23 are heated. Then, even when the oil is stuck to these parts, the oil is not set but flows down and falls on an oil receiver 30. Accordingly, the basket 21 is always ascended and descended smoothly.

Title: Semiconductor device and its manufacture
Inventor: NAKAMURA SHINJI
IPC: H01S5/343
Filed: 1999-10-22
Abstract: PROBLEM TO BE SOLVED: To manufacture a highly precise waveguide structure with good control and thereby enable single transverse mode oscillation, by forming a second conductive type first semiconductor layer, whose Al composition ratio is smaller than that of a first conductive type etching stop layer on the etch stopping layer. SOLUTION: Since an etch stopping layer 17 whose Al composition ratio is larger than that of an n-type current blocking layer 12 is formed immediately below the n-type current blocking layer 12, etching of the n-type current blocking layer 12 can be blocked in the etch stopping layer 17. Therefore, it is possible to accurately and uniformly control the etching depth of the n-type current blocking layer 12 and to obtain a waveguide structure which is more precise than a conventional one. A first p-type clad layer 8 whose Al composition ratio is smaller than that of the etch stopping layer 17 is formed immediately below the etching stop layer 17. Since the lower the Al composition ratio is, the is larger the refractive index, therefore, light confinement can be carried out well in this structure.

Title: Shuttle control method for dot line printer
Inventor: HOSAKA MAKOTO
IPC: B41J19/18
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To enhance print speed even in case of short paper feed time by applying a thrust lower than that of an inversion energizing means reversely thereto immediately before inversion of a hammer mechanism section and starting acceleration in synchronism with the end of sheet feed. SOLUTION: When a large number of lines are fed, a control section driving section 58 performs deceleration control of a hammer mechanism section 55. Low speed motion control is started when a shuttle is detected in the vicinity of an inverting position during deceleration control. In the low speed motion control, a motion power slightly weaker than the thrust of an inversion energizing means is applied reversely in order to move the hammer mechanism section 55 at low speed. Furthermore, an acceleration start time is set in synchronism with the paper feed in case of multiple line feed and acceleration control is started when an acceleration control time is reached. According to the control method, shuttle operation can be controlled with no lag in synchronism with the paper feed in case of multiple line feed.

Title: Method of evaluation of strand insulating treatment level for stranded wire
Inventor: MORII AKIRA
IPC: H01B13/00
Filed: 1990-11-09
Abstract: PURPOSE:To evaluate a strand insulating treatment level continuously and quantitatively by inducing a high-frequency current inside a stranded wire conductor subjected to strand insulating treatment and measuring physical quantities according to the amplitude of the induced current. CONSTITUTION:In a stranded wire conductor 2 subjected to strand insulating treatment, an insulator film is formed on an individual strand constituting the conductor 2, so that when a high-frequency current is induced inside the stranded wire conductor 2 by means 5 for applying a high-frequency magnetic field to the conductor 2 and the like, an induced current flows through the individual strand. In contrast with it, in the stranded wire conductor not subjected to the strand insulating treatment, the induced current flows through the outer-most layer strand of the stranded wire and only the surface between strands. Accordingly, it is made feasible to evaluate the quality of the strand insulating treatment by measuring physical quantities (temperature 6, current 7, inductance 8, etc.) according to the amplitude of the induced current. Thereby, the insulating treatment level may be evaluated without dismembering the stranded wire conductor and continuously.
