Filed: 1992-09-07
Abstract: PURPOSE: To provide an optoelectronic device, with which the increase in quanta is prevented from decreasing by removing at least a lower limit layer at a location positioned at the lower part of a photodetector. CONSTITUTION: A lower limit layer CIC, a guide layer CG, an upper limit layer CSC and an absorption layer CA are deposited on a substrate S by epitaxy, and a guide ribbon RG and the absorbtion layer CA are etched, so as to be formed into a mesa. Therefore, they are side etched to the limit layers and guide layers. For contacting one part of the lower surface of a guide layer CG at the lower part of the absorbtion layer at least with air, the lower limit layer CIC at the lower part of at least one part of mesas 4 and 6 is partially removed.

Title: Parallel data transmission system
Inventor: YAMAUCHI MASAKI
IPC: H04L69/14
Filed: 1998-08-25
Abstract: PROBLEM TO BE SOLVED: To transmit data efficiently even when using plurality of lines whose communication quality differs from each other by starting transmission of the data through plurality of the lines only when all of plurality of the lines suffice the communication quality requirements. SOLUTION: A host interface section 12 provides communication quality requirements to a transmission request of a host layer 11 and gives the transmission request with the quality requirements added thereto to a line integration section 13. The line integration section 13 connects with plurality of line control sections 141-14n, analyzes the quality denoted in the transmission request with the quality requirements added thereto by taking the number of connection of the line control sections 141-14n and a physical transmission rate of lines into account, and commands setting of connection to the line control sections 141-14n.  In this case, the line integration section 13 discriminates whether or not all of plurality of the lines suffice the communication quality requirements, and starts transmission of data through plurality of the lines when all of plurality of t lines suffice the communication quality requirements. Thus, no data transmission is conducted when there is one line at least that does not satisfy the communication quality requirements.

Title: Image forming device
Inventor: INABA YUTAKA
IPC: G03G16/00
Filed: 1985-10-25
Abstract: PURPOSE:To reduce the size of the whole image forming device without any deterioration in picture quality by applying an alternating voltage between two electrodes between which an insulator is sandwiched and causing discharge in the air gap part between the electrodes. CONSTITUTION:The 1st electrode 11 is applied with an alternating voltage successively on a time-division basis and positive and negative ions are generated alternately at openings of the 2nd electrode 12 in the column applied with said alternating voltage. Further, the electrode 12 is applied with a high or low signal from an image signal source 28. When the high signal is sent out, the potential of the electrode 12 is higher than the potential of the 3rd electrode 13, so negative ions are discharged to the electrode 13 and never reach a recording medium 2. When the low signal is sent out of the signal source 28, on the other hand, the negative ions are attracted by the potential of a conductive substrate 5 where a medium 2 is set to charge the medium 2. Thus, the negative ions stick on the medium 2 according to the low signal of the signal source 28. The medium 2 moves as shown by an arrow and the alternating voltage is applied to the electrode 11 successively on a time-division basis at a speed synchronized with said moving speed.

Abstract: PURPOSE:To easily perform both-side copying, by separating a document from an original document table and conveying the document to be inverted once stored in an intermediate staying part thereafter exposing the original in an exposure part to be collected again to the exposure part or to the document table by a switching pawl. CONSTITUTION:A document, mounted onto an original document table 6, is fed to an advancing plate 26 by a call roller 20 and inverted by a separating roller 22 and an inhibiting belt 24. The original is fed to an intermediate staying part 42 by paired rollers 32, 34. Next the original, which is conveyed by rollers 50 by reversing the paired roller 34, is fed between a platen glass 2 and a belt 52. The platen glass 2 reads the original by the original through method or the optical system scanning method. The original, when its one-side copying is performed, is conveyed by rollers 68R, guided by guide plates 70, 72 and collected to the table 6. The original, when its both-side copying is performed, is distributed to the platen glass 2 by a gate 66, reversed by the belt 52 again set to the platen glass 2 and exposed. In this way, the original which can select the optical through method or the optical system scanning method to easily perform both-side copying, improves productivity.

Abstract: PROBLEM TO BE SOLVED: To obtain a molding material which can give a molding excellent in fatigue strength, impact strength, and abrasion resistance by mixing a novolac phenolic resin with hexamethylenetetramine, a finely ground glass fiber, and a ground cotton fabric. SOLUTION: It is desirable that the resin is a random novolac resin, a high- ortho novolac resin or the like, and if necessary, 30-60 wt.% of the whole molding material of a resol type phenolic resin can be incorporated. The mixing amount of hexamethylenetetramine is preferably 7-30 pts.wt. per 100 pts.wt. novolac phenolic resin. The finely ground glass fiber is desirably an unbound one having a fiber diameter of 5-15 μm and a fiber length of 30-500 μm and can reduces abrasiveness to, especially, a metal. The ground cotton fabric is added for the purpose of maintaining and improving the fatigue strength and impact strength of a molding and is desirably one having a fiber length of 0.2-3.0 mm.  The combination of the finely ground glass fiber with the ground cotton fabric permits the molding material to give a molding having the features of both and showing counterbalanced defects of both. The material is suited for machine components of e.g. an automotive brake piston.

Title: Horizontal expansion control method of printer
Inventor: FUJII TAKEO
IPC: B41J2/485
Filed: 1986-10-09
Abstract: PURPOSE:To enable output of printing an double a normal speed by pairing an odd-numbered dot column of a font and an even-numbered dot column which follows the former and doubling the number of pairs through repetition of operation of each pair for horizontal expansion. CONSTITUTION:'n' th dot column and (n+1)th dot column are paired as shown by a dot line 1 before expansion, and this paired operation applies to the entire area of a dot line. Next, each paired operation is repeated twice each time so that the number of pairs is doubled as a whole. As a result, 'n'th dot column before expansion corresponds to (2n-1)th dot column and (2n+1)th dot column after expansion, and (n+1)th dot column before expansion corresponds to {2(n+1)-2}th dot column and 2(n+1)th dot column after expansion. Thus such corresponding printing dots are obtained and the printing dots are horizontally expanded without any connection on the dot column. Consequently, it is possible to print horizontally doubled characters at double a normal speed without degradation of printing quality.

Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To make it possible to surely take in data of a sort having a high data updating rate and send the data to a transfer destination as newest data, in a double buffer circuit for temporarily storing received data combining data and a label indicating the sort of the data in a double buffer as a pair, reading out stored data asynchronously with the received data and sending the read data to the transfer destination. SOLUTION: A label detection part 3 detects a label indicating the data sort of received data, a holding part 5 holds the detected label and a comparator 9 compares the detected label with all reference labels registered in a label registering PROM 8. When a buffer switching condition judging circuit 30 judges that the label at the time of coincidence is a previously set label (having a large updating rate), two buffer writing/reading states in the double buffer circuit 20 are controlled so as to be switched synchronously with a reference trigger (the initial timing of transmission data format operation in a data transfer destination 12) generated immediately after the judgement.
