Title: Manufacture of semiconductor device
Inventor: TAKAKURA TOSHIHIKO
IPC: H01L29/812
Filed: 1984-02-10
Abstract: PURPOSE:To improve the element yield by improving the withstand voltage of Schottky gates by a method wherein a gate electrode is wet-etched or plasma- etched after the N<+> diffused layers of source and drain are formed. CONSTITUTION:Using the gate electrode 4 as a mask, the N<+> diffused layers 5 of source and drain are formed by another Si<+> ion implantation. Next, the surface of the gate electrode 4 is etched by wet etching over the entire surface with e.g. hydrogen peroxide after removal of a photo resist film 3. Since side etching generates in the lower surface of the gate electrode 4, the distance between the N<+> diffused layer 5 and the gate electrode 4 becomes long enough to secure sufficient Schottky barrier levels in spite of light etching, resulting in the improvement of withstand voltage of the Schottky gate, of the product yield and reliability.

Title: Manufacture of multilayer wiring board
Inventor: NAKAMURA KIYOTOMO
IPC: H05K3/46
Filed: 1994-01-21
Abstract: PURPOSE:To provide a simple multilayer wiring board manufacturing method with which poor adhesion of an inner layer circuit board and an adhesive insulating layer can be prevented and the treatment solution used in the course of manufacture hardly remains on the interface of the above-mentioned circuit board and the insulating layer. CONSTITUTION:When the copper foil wiring layer 1 of an inner layer circuit board is surface- treated and a multilayer wiring board is manufactured by laminating a plurality of inner layer circuit boards through the intermediary of an adhesive insulating layer, a blacking treatment, using an adhesive oxidation treatment solution, as a surface treatment and an oxidation treatment, using phosphoric acid treatment solution containing pH of 0 to 3%, are conducted. By the above-mentioned treatments, very fine recesses and protrusions are formed on the surface of the wiring layer 1, and the adhesive strength between the wiring layer 1 and the adhesive insulating layer can be improved. Accordingly, as the infiltration of the treatment solution between the wiring layer and the adhesive insulating layer is suppressed even when the treatment is conducted by an oxidation solution in the course of manufacture of the multilayer wiring board, the occurrence of a haloing phenomenon can be suppressed, and the treatment solution used in the manufacture does not remain on the interface. Also, as the pH stability of phosphoric acid is excellent, a number of circuit boards can be oxidation-treated continuously.

Title: Authenticity inspector for gold
Inventor: YOSHIDA MOTOHIKO
IPC: G01N29/07
Filed: 1982-02-15
Abstract: PURPOSE:To facilitate the evaluation on the authenticity of a gold nugget or the like and the presence of foreign matters therein by setting a measuring range of material to be inspected corresponding to the weight thereof and observing it therein with a measuring range selector switch provided in at least more than one step of the weight unit. CONSTITUTION:Branded article such as a gold nugget is manufactured in standard dimensions established in terms of weight according to each brand name. Therefore, the thickness of a nugget and a gold plate 3 depends on the brand and the weight thereof and the rising position of an observation waveform is observed in variations within a dimensional range allowable in the manufacture. In response to any change in the thickness of the plate 3, the rising position of a wave to be observed varies. When the thickness of a gold plate 3 changes, the observation waveform B shifts to the left of a screen of a Braun tube 11, for example, in a thin plate, while it projects to the right thereof in a thick plate. The measuring range should be changed over to set the observation waveform B to the easily visible position in the CRT11. This enables even a non-skilled person to evaluate the authenticity of a nugget or the like or the presence of foreign matters therein easily.

Title: Control of continuous heating furnace
Inventor: TAKAHASHI RIYOUICHI
IPC: C21D9/00
Filed: 1978-02-27
Abstract: PURPOSE:Preliminary temperature measurements are made on warm steel strips in hot charging before they are inserted into continuous reheating furnace, and the temperature of the furnace is controlled accordingly, thereby effecting the reduction of fuel unit consumption. CONSTITUTION:The temperature of warm steel strip is preliminarily determined before it enters continuous reheating furnace. To effect this, the measurements are made on the steel strip temperature immediately after blooming and rolling or continuous casting, as well as the time between the temperature measurement ans steel strip insertion into the furnace. Both temperature and time are used to determine the temperature at which the steel strip enters the furnace. Alternatively, the temperature can be measured just before the steel strip enters the furnace. Based on the determined temperature, the precalculated formula is used to control temperatures at each zone in the furnace so that the steel strip may be extracted at a preselected temperature.

Abstract: PURPOSE: To improve the throughput of a system by giving more opportunities of communication to the responder, which fails in communication to have a higher frequency in retry, to increase the number of assigned time slots at the time of existence of plural responders in the communication area. CONSTITUTION: A responder 3 is provided with a retry frequency storage means where the frequency in retry with which communication should be re-established at the time of a failure of communication establishment to an interrogator 1 is stored. When receiving an ID transmission invitation signal from the interrogator 1, the responder 3 selects a pertinent assigned time slot in accordance with the frequency in retry stored in the retry frequency storage means ana transmits an ID transmission signal. Since the number of assigned time slots is increased in accordance with the frequency in retry, different time slots are assigned to individual responders 3 if the frequency in retry is different by responders 3 even in the case of the same number of responders 3 which transmit the ID transmission signal, and therefore, a probability of collision of responses is reduced.

IPC: H04L12/70
Filed: 1992-02-10
Abstract: PURPOSE:To measure the propagation delay of a packet switching network without taking synchronism between terminal equipments. CONSTITUTION:A terminal equipment 20 sends the data of a packet whose sequence number is '0' in a timing to a switching network 10 through a TXD signal line and the packet data are inputted to a terminal equipment 30 through the switching network 10 and an RXD signal line.

Abstract: PURPOSE:To operate automatically the valve correspondingly to a casting or a completion signal by a method wherein in a vacuum exhaust port connecting the upper portion of a cavity to the outer portion thereof is provided a discriminating member that allows gas to pass and does not allow viscous liquid such as molding material to pass. CONSTITUTION:The filter as the discriminating member that allows gas to pass but does not allow viscous liquid such as molding material to pass is fitted in  the vacuum exhaust port 3 connecting the upper portion of the cavity 2 of the  mold 1 to the outer portion thereof. The pressure in the cavity 2 is reduced by  the vacuum pump 8. When the detection value of the vacuum switch 6 reaches  2 value Vs, the vacuum switch 6 gives a signal and the ON-OFF valve 9 is  opened to begin casting of the material. When the cavity 2 is filled with the molding material and the material hits against the filter 4, the degree of vacuum increases more rapidly and takes a value VE. At this time, the vacuum  switch 6 operates to close the ON-OFF valve 9 through an solenoid valve 10.
