Title: Glass wafer and method for detecting surface position thereof
Inventor: KAWASHIMA HARUNA
IPC: G03F9/00
Filed: 1990-06-07
Abstract: PURPOSE:To automatically detect and correct an error caused in the thickness of a glass wafer by forming a film having a prescribed reflectivity against the detecting light of an automatic focus detector on the rear of the wafer and, at the same time, another film which does not transmit the detecting light in a part of the surface of the wafer. CONSTITUTION:In order to correct a detecting error component caused by reflected light 5b from the rear of a glass wafer substrate 1, surface position detection is performed on the area 2 of a glass wafer in addition to the other area 3 of the wafer by using the glass wafer partially formed with a light shielding film 7 which does not transmit detecting light. In the area 2, a film 7 of, for example, Cr, two-layer Cr, which does transmit the detecting light is formed on the substrate 1. When the area 2 is constituted in such way, no detection error occurs and it is confirmed that a surface position detecting quantity catches the surface of a photoresist 8, because the reflected light from the rear surface of the substrate 1 does not exist and, accordingly, no detection error occurs. The detection error caused by the reflection of the detecting light at the rear surface of the substrate 1 in the area 1 can be confirmed from the difference between the detecting quantities in the areas 3 and 2. Therefore, an erroneous value in surface position detecting values caused by the reflected light from the rear surface of the glass wafer substrate can be detected automatically.

Title: Semiconductor light-emitting element
Inventor: UJI TOSHIO
IPC: H01S5/00
Filed: 1984-07-20
Abstract: PURPOSE:To enable the oscillation threshold value to be decreased, by providing semiconductor layers respectively having first and second conductivity types around a luminescent region, and externally controlling the potential at a part of these semiconductor layers. CONSTITUTION:An n type semiconductor layer 11, an n type semiconductor active layer 12 and a p type semiconductor layer 13 are formed into a stripe mesa configuration. A p type semiconductor layer 14, an n type semiconductor 15 and a p type semiconductor layer 16 are successively formed on eash side of the mesa. First, second and third electrodes 17, 18 and 19 are formed on the surfaces of the layers 16, 11 and 15, respectively. When a forward voltage VF is applid between the electrodes 17 and 18, current is injected into the layer 12, and light is emitted. However, a part of the current passes through the layer 14 to leak out. When a positive voltage V is applied to the electrode 19, the layers 15 and 14 are reverse-biased, so that the depletion layer in the layer 14 spreads to decrease the leakage current. By externally controlling the potential at the layer 15 in this way, it is possible to control the leakage current and lower or control the oscillation threshold value.

Each bunch of hair slides deep along the gap between the flexible plate springs 4 as the teeth 3 of the comb 10 enter into the hair. Restoring force of the adjacent plate springs 4 securely holds even thin hair.

IPC: G01R21/133
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To accurately measure three-phase active power, reactive power and apparent power even when there are unbalance of a three-wire load and waveform distortion by measuring a phase current of first/third phases of a three-phase alternating current, measuring interphase voltage of first/second phases and second/third phases, and separately performing an operation on the real number part and the imaginary number part of interphase voltage and an interphase current from a result of a Fourier analysis. SOLUTION: In a phase current A1 of a first phase, a prescribed signal is obtained in an output terminal 27 of an FFT processor 22 by performing a Fourier analysis, and in interphase voltage V1 of first/second phases, a signal is obtained in a terminal 17. A complex multiplier 13 performs multiplying processing on the signals of the terminals 27, 17 by a prescribed expression to output interphase active power W1 of the first/second phases to a real number part output terminal 15, interphase reactive power var1 to an imaginary number part output terminal 25 and similarly active power W3 and reactive power var3 to terminals 35, 45. An adder 14 obtains three-phase active power ΣW in an output terminal 16 by performing adding processing on the powers W1, W3, and an adder 34 similarly obtains Σvar.  A square sum extractor 50 obtains ΣVA of three-phase apparent power by the active power and the reactive power Σvar to thus determine active/reactive apparent powers without an error.

IPC: G03G21/10
Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To prevent the deviation (color smear) between toner images with exposure at first and second exposure positions, caused by the frictional force of a reciprocating operation, in an image forming device which is provided with plural exposure means and reciprocates a cleaning blade brought into contact with the surface of a photoreceptor. SOLUTION: Electrostatic latent images are formed on the surface of a photoreceptor drum 1, at the first exposure means M1 , to form a red toner image and at the second exposure means M2 , to form a black toner image respectively and then, they are transferred to a transfer material. Toner remaining on the surface of the photoreceptor drum 1 is removed in such a manner that the cleaning blade 10 arranged in contact with the surface of the drum 1 is moved back and forth in a generatrix direction. The red and black toner images have the color smear, because of friction at this time.  In such a case, when time to move the surface of the drum from the first exposure position M1 to the second exposure position M2 is defined as TD and time to make a reciprocation of the cleaning blade 10 by a reciprocating mechanism is defined as TA, TA=TD×1/n (n: positive integer) can be satisfied to prevent the color smear.

Title: Document processor
Inventor: SUZUKI TADASHI
IPC: G06F17/30
Filed: 1988-06-20
Abstract: PURPOSE:To substitute a document data for the character of desired attribute even when the character of the different attribute is mixed, and to widely shorten the working time of editing by searching the character according to the designated contents of the attribute, and substituting the character with the designated attribute. CONSTITUTION:Document data has a character code corresponding to each character and an attribute code corresponding to the character code. When a CPU decides whether the condition 'to substitute the attribute of a character string to be substituted' is designated or not, and when it is not designated, the CPU makes the attribute data of the character string to be substituted same as the attribute data of the first character of a coincident character string. Then, in a case that the attribute data of the coincident character string is substituted for the attribute data of the character string to be substituted, or in a case that designation 'to substitute the attribute of the character string to be substituted' is designated previously, the CPU deletes the attribute data corresponding to the coincident character string, and inserts the attribute data of the character string to be substituted. Thus, the time of the editing work can be shortened.
