Title: Semiconductor light receiving device
Inventor: MINEO AKIYOSHI
IPC: H01L31/02
Filed: 1981-05-26
Abstract: PURPOSE:To sharpen the leading lightreceiving sensitivity by a method wherein the material with the energy gap near the photon energy with the wave length to be eliminated is added to the sealing resin substituting for the coloring matter. CONSTITUTION:The sharp sensitivity at the absorbing end as the property of a semiconductor is utilized by means of providing the resin with the energy gap. For example, when fibrinogen as a material with the energy gap is added to epoxy resin used for sealing silicon pin photo diode at the weight ratio of say 10:1, the leading lightreceiving sensitivity characteristics to the wave length is extremely sharpened. The preferable energy gap ranges from 1.3eV to 2.0eV while in order to reduce the sensitivity to the fluorescent lamp, the range from 1.3eV to 1.6eV is recommended.

Filed: 1988-03-31
Abstract: PURPOSE:To attain connection to another system pinched with trouble systems and to continue data transmission by providing an optical bypass circuit composed of a divider and an optical switch in the connecting part of an optical fiber cable. CONSTITUTION:An optical switch 81 is normally in closing condition and becomes an opening condition by a driver 200 only when a processing system 1 executes the transmission. When the system 1 is separated from a connecting part 8, the switch 81 becomes the closing condition.

Title: Laser printer
Inventor: SASAKI AKIRA
IPC: B41J2/00
Filed: 1991-04-12
Abstract: PURPOSE:To provide highly accurate picture print by setting a period of laser beam deflection to 1/n of a prescribed deflection scanning period and frequency- dividing the frequency with a main scanning synchronization generating means so as to adjust the print position. CONSTITUTION:A period of laser beam deflection by a deflector is set to 1/n of a prescribed deflection scanning period. A counter 276a of a detection signal processing circuit 276 frequency-divides a deflection operation start reference signal BDT into 1/n and outputs the result. Then a deflection scanning start main reference signal BDT2 in phase with a frequency division output is inputted to one input terminal of an AND circuit element 276e. Moreover, a deflection scanning sub reference signal BDT3 in opposite to the frequency division output is inputted to the other input terminal of the AND circuit element 276e. When a subscanning direction reference position detection signal HPS is generated and the generated timing signal BDT2 is at a high level, an output terminal Q2 of F FF 276v goes to a high level and an output terminal Q3 goes to a low level. Then the signal BDT3 passes through the element 276e, from which an effective signal is obtained. Thus, highly accurate picture print is attained.

IPC: G05D3/12
Filed: 1981-05-26
Abstract: PURPOSE:To detect accurately a backlash amount after each change of the backlash amount if occurs, by detecting and measuring the backlash amount with use of a machine tool itself. CONSTITUTION:When a table 10 is moved toward an arrow, a reference tool 50 and an object 34 to be worked come into contact with each other and the electric signals e1 and e2 are delivered from the pressure sensors 52a and 52b, respectively. These output signals are amplified by an operational amplifying circuit 54 and via the resistances R1 and R2. Thus the output e0 of the circuit 54 is set as e0=(e2-e1)XR2/R1. The output e0 is compared with the reference voltages V1 and V2 through the comparators 56 and 58. Then the signals S0 and S1 are delivered from the comparators 56 and 58, respectively. If the pressure is applied unevenly to the sensors 52a and 52b, an output S2 is produced from an OR gate 64. At this time point, a table 10 is shifted in the direction opposite to an arrow to detect the position where the outputs S0 and S1 of the comparators 56 and 58 plus the output of the gate 64 are set at zero, respectively. This position indicates the backlash amount, i.e., the value obtained by synthesizing a gas and a blind sector.
