Title: Hetero junction bipolar transistor
Inventor: HONJO KAZUHIKO
IPC: H01L29/205
Filed: 1986-10-03
Abstract: PURPOSE:To obtain a hetero junction bipolar transistor in which a substrate current is not generated by providing a semiconductor layer having smaller electron affinity than a collector layer between the collector layer and a semi- insulating semiconductor substrate. CONSTITUTION:A first semiconductor layer 13 as an n-type (or p-type) collector layer, a second semiconductor layer 12 as a p-type (or n-type) base layer and a third semiconductor layer 11 as an n-type (or p-type) emitter layer having at least wider forbidden band width than the layer 12 are sequentially formed on a semi-insulating semiconductor substrate 15. In such an emitter top type hetero junction bipolar transistor, a fourth semiconductor layer 14 having smaller electron affinity than the layer 13 is formed between the layer 13 and the substrate 15. For example, the nondoped Al0.25Ga0.75As layer 14, the n-type GaAs layer 13, the p-type GaAs layer 13 and the n-type Al0.25Ga0.75As layer 11 are sequentially formed on the substrate 15 to construct a bipolar transistor.

Title: Information processor and information processing method capable of suppressing branch prediction
Inventor: NAKADA TATSUKI
IPC: G06F9/32
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To improve the prediction of the action of an event wait branch loop and to accelerate the escape speed of the loop concerning an information processor for performing pipeline processing with branch prediction. SOLUTION: When the branching instruction of event wait is detected, a decoder 110 asserts a signal DNO-PRD. Corresponding to this assert, an AND circuit 11 negates a signal D-HINT for branch prediction and an AND circuit 112 negates a write signal E-PC of a branch prediction table 23. Therefore, the branch prediction is suppressed and the prefetch of an instruction following the branching instruction is promoted.

Filed: 1986-10-06
Abstract: PURPOSE:To display instantanously a program index when a channel is designated again by separating program index data fetched once from other data and recording and preserving them together with a channel number for a channel. CONSTITUTION:The packet data of a program index are read from the character signal extracting circuit of a teletext receiver through a packet data input terminal 1 to an arithmetic control circuit 2. The data are accumulated to a packet memory circuit 3 for a program index in accordance with the storing program of a control memory circuit 4 of a control memory circuit 4 to provide a receiving channel number identifying data recording area. For example, in a channel number '2,' while the receiving of program index data is completed, the channel number and the program index packet data storing address of the said channel are written. At this time, when the channel number '2' is requested, the arithmetic control circuit 2 retrieves the channel number '2' from the control memory circuit 4, sends successively accummulated packet data to an image displaying circuit and displays them as a program index.

Abstract: PROBLEM TO BE SOLVED: To facilitate the installation work of a disaster preventive sheet, while preventing the heating of a cable and reducing the influence on an allowable current of the cable, by making the sheet in such a structure that a fireproof heat insulation layer which has a characteristic heat resistance within a specified range is formed on a metallic base material via an adhesive layer. SOLUTION: A disaster preventive sheet is made by forming a fireproof heat insulation layer 3 on a metallic base material 1 via an adhesive layer 2. As for the base material 1, a stainless sheet or an iron plate or the like plated on its surface with zinc or the like is used. For the adhesive layer, a chloroprene rubber adhesive, an olefin adhesive, an acrylic adhesive or the like is used. For the heat insulation layer 3, carbon fiber is combined with aramid fiber, fire-resistant rayon, and heat-resistance acrylic fiber. A characteristic heat resistance of the heat insulation layer 3 is set to 500-2500 deg.C.cm/W. Due to this structure, the sheet can be installed easily and quickly, even on a cable pipe laid along a bridge. Furthermore, the sheet does not disturb radiation from a cable of normal times, and there is no effect on an allowable current of the cable.

Abstract: PROBLEM TO BE SOLVED: To prevent pollution of work environment due to flopping down of oil by blowing an infinitesimal of lubricating oil directly against an object, such as a cutter, together with a jet of air during cutting work and to perform removal of chips and cooling of an object simultaneously with lubrication of a cutter. SOLUTION: This feeding unit is provided in a position, situated downstream from a filter/regulator 1, with an air switching valve 2. A flow in a position situated downstream from the air selector valve 2 is branched into an air line L1 to spray lubricating oil and an air line L2 for driving a pump guiding to the drive feed ports 7c and 7c of a metering discharge pump unit. Thus, when the air selector valve 2 is energized, a valve is opened and air flows toward the nozzle adapters 3 and 3 sides (the air line L1) and the intermittent pulse generator 5 side (the air line L2). Air flowing from the air switch valve toward the nozzle adapters 3 and 3 from the air selector valve 2 is regulated in the middle to an air flow rate suitable for application by air flow rate regulating valves 6 and 6.  The intermittent pulse generator 5 consists of, for example, a 3-port solenoid valve and an air pulse generator to control an air pulse. Each time an intermittent pulse is outputted two discharge pumps 7 and 7 are simultaneously operated and air and oil are intermittently fed.
