Filed: 1991-06-24
Abstract: PURPOSE:To provide the spot of a variable-resolution scanning optical system capable of expanding the spot diameter in the auxiliary scanning direction without reducing the utilization efficiency of the light flux from a light source section. CONSTITUTION:A cylindrical lens constituting the first image forming optical system 2 is displaced from the initial position toward a light source section 1 or a rotary polygon mirror 3 on the optical axis direction as shown by an arrow 8 for controlling the spot diameter in the auxiliary scanning direction on a scanned surface 6 in order to change the resolution. The image forming position in the main scanning direction is not changed, the image forming position in the auxiliary scanning direction is changed, and the spot diameter in the auxiliary scanning direction on the scanned surface is expanded due to de-focusing. A scanning optical system capable of changing the resolution without reducing the light utilization efficiency can be provided, and it is suitable for a scanning optical system for a laser beam printer required to change the resolution in the auxiliary scanning direction in particular.

Abstract: PURPOSE: To enhance workability by inserting an inserting-installing body arranged on a fittings frame in a receiving body arranged in an opening part, and fitting and fixing a hook-shaped locking part arranged on the inserting-installing body tip to a claw-shaped member arranged in the receiving body. CONSTITUTION: A shaft 7 of an inserting-installing body A installed on a going in and out frame 3 is inserted in a hole of a main body cylinder 13 from the pressing plate 18 side of a receiving body B installed on light iron 5. Next, a tip slant face part of the shaft 7 is brought into contact with an inside slant face of a claw body 14, and the claw 14 is push opened outside, and is penetratingly passed. Next, the tip of the claw 14 comes into contact with a circumferential surface of the shaft 7 by energizing force of a helical spring 15, and can be fitted in a hook-shaped locking part formed in a tip part of the shaft 7.  Even if the shaft 7 retreats in the slipping-out direction when a load is applied to the inserting-installing body A, an outer peripheral edge part of the claw 14 comes into contact with a claw cover plate 16, and the tip of the claw 14 is fitted in the hook-shaped locking part, and does not retreat more than that. Therefore, a frame body can be easily installed without requiring a skilled technique such as welding, and a construction period can be shortened, and construction cost can be reduced.

Title: Edge detection circuit
Inventor: KONDO CHIAKI
IPC: H03K5/1532
Filed: 1992-06-11
Abstract: PURPOSE:To obtain an edge detection circuit which does not malfunction even with the input of a whisker consecutive pulse in which a 2-input NAND circuit has a large L to H level conversion capability and a 2-input NOR circuit has a large H to L level conversion capability. CONSTITUTION:When a whisker pulse waveform is inputted, the inversion of an output of inverters 1, 2a starts at a point A and an output of the inverter 1 is inverted slowly because of the presence of a capacitor C1. On the other hand, a 2-input NAND circuit is rapidly inverted through the inversion of the inverter 2a. However, a 2-input NOR circuit 21 is not inverted at the leading at a point B before an output level of the inverter 1 exceeds a threshold level. Thus, the output of 2-input NOR circuits 12, 13 is also unchanged. When the whisker pulse with the opposite polarity to above is inputted, the output of the inverter 1 is slowly inverted similarly to above. However, the 2-input NOR circuit 21 is inverted rapidly by the inversion of the inverter 2a and the circuit 20 falls down at the point B before an output level of the inverter 1 exceeds a threshold level and then not inverted. Thus, the output of the 2-input NOR circuits 12,13 is also unchanged.

Title: Data transmission method
Inventor: TOKUE JUN
IPC: H04L12/28
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To adopt an error detection method by which the transmission efficiency of large capacity data such as music software data can be enhanced in the case of transmitting the data through the use of a full duplex communication channel. SOLUTION: A sender side transmitter 2 calculates sender side error detection data ERDt from transmission data D by a prescribed algorithm via a full duplex communication line such as a general public telephone network 1, a memory device of a CPU or the like stores the data and transmits the transmission data D with no sender side error detection data ERDt added to them to a receiver side transmitter 6 through a sender side line 5. The receiver side transmitter 6 calculates receiver side error detection data ERDr from received data D' that are transmitted with the same algorithm as that of the sender side and returns the result at least once to the sender side transmitter 2 through a return side line 7.  The sender side transmitter 2 compares the returned receiver side error detection data ERDr with the sender side error detection data ERDt stored in the memory device and discriminates no transmission error when the same data are found and discriminates presence of a transmission error when the same data are not found.

Filed: 1994-06-10
Abstract: PURPOSE:To obtain a curing agent for xerophthalmia containing a spirooxathiolanequinuclidine derivative or its acid adduct as an active component, free from a side effect and having extremely low toxicity. CONSTITUTION:This curing agent for xerophthalmia contains a spirooxathiolanequinuclidine derivative of formula I (R<1> and R<2> are each H, an alkyl, a cyclopentyl, a cyclohexyl, an aryl, a diarylmethylol or an alkyl substituted by one or more than one aryl group) or its acid adduct as an active component and capable of being topically administered by instillation. As a compound of formula I, a salt of 2-methylspiro(1,3-oxathiolane-5,3')quinuclidine hydrochloric acid adduct is especially preferable. The compound of formula I is obtained e.g. by reacting 3-hydroxy-3-mercaptomethylquinuclidine with a carbonyl compound of the formula R<1>-CO-R<2>. This curing agent can accelerate lacrimation by stimulating a muscarine M3 receptor.

Title: Abnormality detecting method of power generating facility using
Inventor: SASAKI KIYOSHI
IPC: F01K25/10
Filed: 1982-09-03
Abstract: PURPOSE:To prevent occurrence of any serious accident such as breakage of a turbine by sensing huntings in the output of a power generator in a Rankin's cycle type cold power-generating facility and thereby knowing that there is any abnormality in the turbine. CONSTITUTION:Low-temp. liquefied gas from a pipe 3, such as LNG, is heated at a condenser 2 by a gasifying medium from a pipe 3 and gasified to be sent in gas phase to the object which utilizes the gas. On the other hand, the liquefied medium is boosted to a certain specific pressure by a pump 6 to be fed into an evaporator, and there evaporated by sea water from a pipe 9. This medium in gas phase rotates the turbine 11 to allow the generator 13 to generate the electricity. If now a lubricant is mixed in the medium to cause abnormal rise of bubble level of the medium in evaporator 8 and if consequently the liquid medium flowing in the turbine 11 has brought about hunting, a sensor 18 as a monitor for varying rate of the output will sense this abnormality as a hunting in the generator 13. An alarm is now emitted. Thus serious accident such as turbine breakage is prevented to ensure enhancement of the reliability in turbine operation.

IPC: G06Q50/30
Filed: 1991-06-25
Abstract: PURPOSE:To smoothly issue a ticket without requiring labor by inputting all information necessary for the issue of a ticket by a bar code. CONSTITUTION:Bar code information necessary for ticket issue is inputted by a bar code input device 1 and decoded by a bar code recognizing part 2 and the decoded contents are transferred to a data conversion part 3 through a data bus 6 and a control part 4. The conversion part 3 analyzes and edits the transferred contents to issuable data and transfers the analyzed and edited data to a printer data part 5 through the data bus 6 and the control part 4. A printer 7 prints out the data stored in the data part 5 on issuing paper, and at the time of ending the printing processing, the device is turned to the input queue state of succeeding information from the bar code input device 1. Thus all information necessary for ticket issue is inputted by the bar code. Consequently the ticket can be smoothly issued without requiring unnecessary labor.
