IPC: H04N5/372
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To improve the sensitivity of a solid-state image pickup element by preventing the occurrence of welding between lenses and effectively utilizing the light beams made incident to inlet-lens gap areas. SOLUTION: In a method for manufacturing a solid-state image pickup element, a solid-state image pickup element having a flattened layer 2 on a substrate, on which a plurality of light receiving sections are formed and concave lenses 8 at the boundaries between convex lenses 1 in the upper part of the light receiving section of the flattened layer 2, is manufactured. The concave lenses 8 are formed by forming concave lens forming patterns 10 with a positive resist in the spaces between the convex lenses 1, after forming the lenses 1 and thermally reflowing the resist.  Since not only the light beams made incident to the convex lenses 1 are condensed to the light receiving sections, but the light beams made incident to the concave lenses 8 are also made incident to the light receiving sections after the light beams are refracted through the lenses 8, the sensitivity of the solid-state image pickup element is improved, and at the same time, the image pickup element which can reduce smear can be manufactured through a smaller number of processes, as compared with the case where the concave lenses 8 are manufactured through dry etching, etc.

Title: Manufacture of light-emitting diode
Inventor: SAWASE KENSUKE
IPC: H01L33/40
Filed: 1986-03-24
Abstract: PURPOSE:To improve the efficiency of the optical extraction of a light-emitting diode manufactured by removing an insulating film existing on an impurity layer in response to the transverse extension section of the impurity layer in heat treatment and increasing the exposed section of the impurity layer. CONSTITUTION:An insulating film 20 is formed onto the whole surface of an epitaxial layer 11 shaped onto a substrate 10, and an opening window 21 in width 1 is formed to the insulating film 20. An impurity is introduced to the surface of the epitaxial layer 11 from the window, and an impurity layer 30 is shaped through heat treatment. Since the impurity layer 30 transversely extends in response to diffusion depth on said heat treatment, the diffusion width of the impurity layer 30 is increased to W2 and made larger than the width W1 of the opening window 21. The insulating film 20 is removed only by a section corresponding to the transverse extension section of the impurity layer 30 in order to eliminate the trouble, and the width of the opening window 21 is broadened to W1' from W1. Accordingly, the whole surface of the impurity layer 30 can be used as an optical extraction surface, thus improving the efficiency of optical extraction.

IPC: B01D53/50
Filed: 1980-05-22
Abstract: PURPOSE: To prevent previously lowering of the desulfurization factor or an occurrence of the fire accident in a desorption process, by providing a sealing member consisting mainly of a gas bag containing a flexible fluid charge discharge part at the desorption zone.  
     CONSTITUTION: A chamber 2 is shifted from an adsorption zone A to a desorption zone B, and the adsorbent in the chanber 2 is heated to carry out a desorption for the sulfur oxide contained in the adsorbed exhaust gas. In this case, the air is supplied via a conduit and a flexible fluid supply/exhaustion port 27, and thus the same pressure air is enclosed into a gas bag substance 25 through a flexible pressure fluid supply/exhaustion port 28 of a shape retaining member 26. The bag substance 25 expands to touch close the pole and beam in the chamber 2 to perform a seal-up function. As a result, the heated gas within the zone B leaks out of the zone B to go into the chamber 2 in another zone to reduce the desulfurization factor. At the same time, the exhaust gas containing the oxygen flows into the zone B to prevent an occurrence of the fire accident.

Title: Optical disk device, optical disk and recording method
Inventor: YAMAGUCHI SHIGEO
IPC: G11B7/007
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To increase data storage capacity used by a user by selectively changing synchronizing control data used for synchronization at the time of reading out the data and recording data to each other in every prescribed time and outputting them. SOLUTION: ODC 3 controls the rotating speed of a disk at the time of recording/reproducing data in an optical disk and modulates/demodulates the data. The ODC 3 also inputs a data signal S1 from a host computer 2 to an encoder 10. The encoder 10 modulates the signal S1 and sends it to a switch 11. A VFO signal S11 generated in a VFO signal generating part 12 is sent to the switch 11. The signal S11 is generated with a shorter period compared with one period of a VFO pattern following an encoded restricting length as conventional one. The signal S11 thus generated and the modulated signal S1 are inputted to the switch 11. The switch 11 changes over the signal S11 and the signal S1, sends it as a recording data signal S2 and it is recorded in the optical disk.

Title: Lateral type transistor
Inventor: TABATA TERUO
IPC: H01L29/73
Filed: 1979-05-29
Abstract: PURPOSE:To prevent the decrease of a current amplification factor by a mechanism wherein one conduction type layers are formed surrounding collector and emitter layers on a surface of an epitaxial layer and the collector currents of a parasitic transistor are caught in a lateral type transistor. CONSTITUTION:An N<+> buried layer 16 and an N-epitaxial layer 12 are formed on a P-type substrate 11, and separated by P<+> layers 13. Capture regions 18 are made up to the N-layer 12 at the same time as P-type collectors 14 and an emitter 15. The regions 18 are originally formed so as to surround portions constituting a lateral type transistor, and function as the colletion of reactve currents which cannot be collected to the collectors 14 among positive holes injected from the emitter 15, and the reactive currents elongate a base electrode 20, connect the base electrode to the capture region 18 and are flowed back as the base currents of the original lateral type transistor when forming collector electrodes 19, the base electrode 20 and an emitter electrode 21. Thus, an parasitic effect is remarkably decreased, and the reduction of a current amplification factor is prevented.

Filed: 1983-04-15
Abstract: PURPOSE:To attain an automatic switch between a program area and a data area by providing both program and data areas by one bank respectively and detecting when a CPU reads the program and reads/writes the data. CONSTITUTION:An AND circuit 4 obtains an AND between an operation code fetch signal M1 and a memory read signal MEMR sent from a CPU 9, and the output of the circuit 4 is latched by a byte number detecting circuit 6 as a strobe signal of the circuit 6. The circuit 6 delivers the byte number and supplies it to an input A at one side of a comparator 8. While a counter 7 has count-up at the fall of the address latch signal, and this output is supplied to an input B of the circuit 8. A coincidence signal is delivered when the coincidence is obtained between the byte number fed to the circuit 8 and the count value of the counter 7. Thus the reading is over with the program. For the subsequent read/write operations, an FF 3 is reset and switched to the bank address of data. Thus an automatic switch is possible between the program and data areas with use of the coincidence signal of the circuit 8.

Title: Internal combustion engine having combustion heater
Inventor: SUZUKI MAKOTO
IPC: F02M31/06
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent contraflow of combustion gas of a combustion heater inside the heater. SOLUTION: A part of intake boosted by a compressor 15a of a turbocharger 15 is supplied to a combustion heater 91 through an air supply pipe as combusting air. Combustion gas from the combustion heater 91 is discharged to an exhaust passage 42 on an upstream side of an intake passage 14 or a catalytic converter 39 through a combustion gas discharge pipe 73 or a branch pipe 84. A check valve 96 is arranged between a rotary fan 90 of the combustion heater 91 and a combustion chamber 48. The check valve 96 allows the combusting gas (combusting air) to flow from the side of the rotary fan 90 into the combustion chamber 48, and prevents the gas (combustion air) from flowing in the opposite direction.  When the air supply pipe 71 is broken and communicated with the atmosphere, the check valve 96 is closed for preventing the combustion gas from flowing from the combustion chamber 48 to the rotary fan 90.
