Title: Optical scanner
Inventor: KANEHASHI HIROTO
IPC: G02B26/10
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To prevent an excessive stress on optical members of an optical scanner. SOLUTION: As shown in FIG. (A), when an adjusting screw 48 is screwed in with one end part of a bracket 46 latched by a pawl 53, a mirror 23 is deformed in the curvature and a bow of a scanning line is adjusted. In a distribution process of an optical scanner or an image-forming device, a bracket lock 52 is deformed in the direction of the arrow B in FIG. (A), and the pawl 53 and the bracket 46 are released from engagement as shown in FIG. (B) to release the bracket 46 from latching. Then, the adjusting screw 48 cannot push on the mirror 23, and the mirror 23 returns to the free state before the adjustment by its own elasticity. Since no stress acts on the mirror 23, it is possible to prevent the mirror 23 from damage caused by vibrations, shocks, etc., during transportation.

Title: Silver halide photographic sensitive material containing novel restrainer
Inventor: EZAKI ATSUO
IPC: G03C1/34
Filed: 1986-02-21
Abstract: PURPOSE:To obtain a photosensitive material having higher sensitivity and higher preservability by incorporating core/shell type silver iodobromide emulsion together with a compd. having a specified thiazole ring and/or an N-contg. heterocyclic compd. CONSTITUTION:Core/shell type silver iodobromide emulsion having higher content of AgI in the core and less content of AgI in the shell is incorporated in a silver halide emulsion layer. Further, a thiazole compd. or benzothiazole compd. expressed by the formula I, and/or an N-contg. heterocyclic compd. expressed by the formula II is (are) incorporated also. In the formulas, Q is a nonmetallic atom group forming a thiazole ring or a benzothiazole ring together with S and N atoms; X is an electron attractive group; Y is H, aliphatic group, aromatic group, etc.; Z<1> and Z<2> are nonmetallic atom groups forming 5-, 6-membered heterocyclic rings; Y<1> and Y<2> are H, or a substituting group. Since such core/shell type silver iodobromide emulsion and a heterocyclic compd. expressed by the formula I or II are incorporated in a photosensitive material, generation of fog in the material is inhibited and the sensitivity of the material is improved.

Abstract: PURPOSE:To obtain an accurate signal by controlling the output of a quantized signal based upon an analog signal detected by an image sensor in accordance with the input value of the analog signal. CONSTITUTION:Only when both the 1st output condition obtained by comparing an analog signal obtained from an image sensor 3 receiving the reflected light on a document with the 1st reference value obtained based upon the peak value of the analog signal by a comparator 23 and the 2nd output condition obtained by comparing the 1st reference value with a previously set up 2nd reference value by a comparator 24 indicate output availability, a quantized signal obtained by quantizing the analog signal is outputted. Namely, the output of the signal is controlled based upon respective output conditions by setting up respective output conditions in accordance with a variation value included in the analog signal. Consequently, the output of an error signal is prevented.

Title: Pseudo-random noise code generator
Inventor: HARADA MASAAKI
IPC: H04J13/10
Filed: 1989-02-20
Abstract: PURPOSE:To allocate code data as a channel number as they are by providing a second shiftregister, for which second pattern data different from first code pattern data are inputted, the initial state of a shiftregister in a prescribed step is fixed and the initial state of the other shiftregister can be changed. CONSTITUTION:In an MSRG 1, MSRG 2 and MSRG 3, two kinds of m-sequence codes can be obtained by supplying the different code pattern data to a PTN 1 and PTN 2. Since the same code pattern data are supplied to the MSRG 2 and MSRG 3, the same kind of the m-sequence code can be obtained. However, concerning the initial state, an n-1 bit is made common for B2-Bn terminals. Then, since 1 bit of a remained B1 terminal is fixed to an 'H' level in the MSRG 2 and fixed an 'L' level in the MSRG 3, the code of a different phase is obtained. Accordingly, in an E1 and E2, the GOLD code of a different pattern is generated without fail.

Filed: 1983-03-09
Abstract: PURPOSE:To hold a fixed toner concentration and to obtain picture quality with uniform concentration by arranging a toner concentration detecting means close to the flow of a two-component developer related to development and detecting always stable and precise toner concentration. CONSTITUTION:A flowing plate 7 is arranged so that the developer 3 regulated by a blade 6 is carried to the back of a mixing spiral 9 and a detecting head 12 of a toner detector is arranged on the lower part of the flowing plate 7 between a sleeve 5 and the mixing spiral 9.

Title: Automatic liquid managing apparatus
Inventor: TAKAIWA SATOSHI
IPC: G03F7/26
Filed: 1990-02-20
Abstract: PURPOSE:To achieve a highly accurate judgment of deterioration by judging that a treating liquid is aged when a peak value of absorbance of the treating liquid measured at a fixed time interval exceeds a reference value and when time exceeds a reference value until the absorbance reaches a reference value from a peak. CONSTITUTION:A treating liquid supplied from a supply system 1, for example, contains sulfuric acid and hydrogenperoxide is cooled with a cooler 2 to remove impurities undissolved with a filter 3 and to measure absorbance with a photo cell 4 and sent to a six-way valve 5. When a fixed amount of an object to be treated, for example, a resist to be generated in a production process of a silicon wafter for a semiconductor is fed into the treating liquid continuously at a time interval, the absorbance immediately after the feeding rises sharply but it lowers in time with the deposition of the resist in the sulfuric acid and hydrogenperoxide. It is judged that the treating liquid is aged when a peak value of the absorbance exceeds a specified threshold while time exceeds a reference value until the absorbance falls below the threshold.

Filed: 1987-02-20
Abstract: PURPOSE:To prevent malfunction just after the changeover by attenuating a tuning voltage at each band from a normal voltage for a defeat period only in switching a reception channel so as to decrease the oscillation frequency of a local oscillator. CONSTITUTION:In depressing, e.g., a switch (SW) SA1 for channel changeover, an input terminal ki of a transmission station control circuit 4 goes to an H level and the oscillation circuit 4a is started. Then the output of the oscillation circuit 4a is counted (4b), decoded (4c) to retrieve transistors (TRs) Q1-Qn, and when a TR Q1 is turned on, the terminal ki goes to an L level and the oscillator 4a is stopped, but the on-state of the TR Q1 is held. A defeat pulse is generated (4e) during the oscillation continuity, a TR Qc is turned on, diodes Dl, Dh, Du are conductive depending on the L, H or U state of VHF of the reception band, thereby decreasing the supply voltage to a band voltage genera tion circuit 5 from the normal value. The supply voltage to an electronic TV tuner 1 is lowered to decrease the local oscillating frequency from the normal value. Thus, malfunction just after band changeover is prevented.
