Patent JP-H11119595-A (JP)
Title: Image forming device
Inventor: SHINOHARA ISATO
IPC: G03G21/00
Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To prevent a density sensor disposed around an image carrier from being soiled with toner. SOLUTION: The output of the density sensor 25 for toner-image density control which is disposed around the intermediate transfer drum 6 is used for other control (for example, the control of the detection of the presence/absence of the intermediate transfer drum 6, the control of the detection of the abnormal condition of the driving system of the intermediate transfer drum 6, or the control of the detection of an amount of toner remaining in a developing device 5) as well as the toner-image-density control. This makes it possible to reduce the number of sensors arranged around the intermediate transfer drum 6 and, therefore, to dispose the density sensor 25 apart from a position where it is susceptible to toner soil, which is the most perilous as it causes the optical sensor erroneous detection, for example, from a position below the developing device 5.  Thus, the density sensor 25 is prevented from being soiled with the toner.

Filed: 1990-10-19
Abstract: PURPOSE:To enable a stable prevention of toner leakage for a long period of time by a method wherein concave portions are formed near both ends of a cleaning blade and seal members are buried and disposed in the concave portions. CONSTITUTION:Concave steps D are formed at both ends of a blade member 3. Seal member 4 is adhered and fixed to the concave step D. The seal member 4 is connected with its stepped part R of the concave step being abutted. As the seal member 4, it is possible to use felt or nonwoven fabric formed of foamed urethane, wool, teflon or the like. In this way, the seal member 4 is fixed to the cleaning blade 3, thereby toner generated in an image forming region at the right side of a dotted line G as viewed in the figure and run in a direction of arrow is prohibited for its advancing operation by the seal member 4 and its dropping into the cleaning device and recovery are carried out. With such an arrangement, it is possible to prevent a overflow of the toner for a long period of time in a stable manner.

Title: Polyarylenesulfide resin composition
Inventor: KAWASHIMA KIYOTAKA
IPC: C08K5/12
Filed: 1990-10-19
Abstract: PURPOSE:To obtain a polyarylenesulfide resin composition having excellent moldability and mechanical properties and suitable for electric and electronic equipment components, etc., by blending a polyarylene sulfide resin with a specific long-chain alcohol phthalic acid ester used as a mold-release agent at a specific ratio. CONSTITUTION:100 pts.wt. polyarylenesulfide resin is blended with 0.01-6 pts.wt. long-chain alcohol phthalic acid ester expressed by the formula (R is CnH2n+1; 25<=n<=70) as a mold-release agent. The mold-release agent is extremely stable even in the molding temperature of polyarylensulfide resin, causes no decomposition thereof and only slightly generates gas without lowering mechanical properties. As a result, the mold-release agent exhibits a good mold-release effect at molding temperatures of an extremely wide range and can shorten molding time.

Title: Large-current circuit board
Inventor: KOBAYASHI TAKASHI
IPC: H05K3/34
Filed: 1996-10-22
Abstract: PROBLEM TO BE SOLVED: To improve the joining strength between circuit conductors and a copper-foil circuit pattern while the conducting capacity is increased and the space is reduced by bending the side edge sections of the conductors in the direction in which the conductors are separated from the circuit pattern and forming fillets between the side edge sections of the conductors and the circuit pattern. SOLUTION: A large-current circuit board is constituted by forming a circuit pattern 20a on an insulating substrate 10 and soldering circuit conductors 30 having side edge sections 30a which are bent in the direction in which the conductors 30 are separated from the pattern 20a to the pattern 20a. In addition, fillets 40c are formed between the side edge sections 30a of the conductors 30 and pattern 20a. Therefore, the conductors 30 are firmly joined to the pattern 20a with high vibration resistances and high heat shock resistances. In addition, even when the amount of solder used for soldering the conductors 30 becomes excessive to some degree, the excessive amount of the solder is prevented from moving to the upper surfaces of the conductors 30 and spoiling the appearances of the conductors 30, because the excessive amount is absorbed between the side edge sections 30a of the conductors 30 and circuit pattern 20a.

Title: A/d converter
Inventor: NENE YOSHITO
IPC: H03M1/36
Filed: 1989-10-30
Abstract: PURPOSE:To prevent the dispersion in a logic level voltage when the conversion speed of an A/D converter becomes higher by providing a buffer circuit between a logic circuit and an encoder. CONSTITUTION:A buffer circuit 3 such as an emitter follower is inserted between a changing point code output and the input of an encoder 4. That is, the buffer circuit 3 inserted between the changing point code output and the input of the encoder 4 supplies the base current of a multi-emitter TR in the encoder 4. As the AD conversion becomes higher, the output of changing point code is changed at fast speed and the multi-emitter TR is operated at a region where hFE is decreased, the base current is increased and the buffer circuit 3 compensates the increment and the pull-in of the current from the pre-stage is not almost changed. Thus, a change in the voltage level of an output of the encoder 4 is prevented.

IPC: F04C29/02
Filed: 1988-11-04
Abstract: PURPOSE:To enable fine capacity control in an about 100% compression capacity by providing a bypath pipe bypassing a screw compressor to fully close a slide valve in the region of about 100% compression capacity and adjust the opening of a bypath adjusting valve in the bypath pipe for the capacity control. CONSTITUTION:In a screw compressor 2 with a slide valve, a change-over valve 11 is controlled by a voltage positioner 8 on the basis of signals from a pressure adjusting meter 7 and an opening transmitter 10. That is, when discharge pressure is increases, the opening of a slide valve 1 is enlarged by a hydraulic cylinder 6 to reduce the capacity of the compressor. When the discharge pressure is reduced reversely, the opening of the slide valve 1 is lessened and the change-over valve 11 is controlled to increase the capacity of the compressor. Then, a bypath pipe 13 branched from a discharge pipe 5 to lead to an intake pipe 3 through a bypass adjusting valve 12 is provided. In the region of about 70-100% of compressor capacity, the slide valve 6 is fully closed to control capacity by the bypath adjusting valve 12.

Abstract: PROBLEM TO BE SOLVED: To perform cooling operation without enhancing a compressor frequency more than necessary by providing a means to perform operation on an operation starting frequency of a compressor on the basis of a target blowoff temperature and an initial blowoff temperature. SOLUTION: Cooling operation finishes, and when a compressor 31 is stopped, a refrigerant is prevented from flowing in a heat absorbing cabin inside heat exchanger 35, and a low temperature-low pressure refrigerant existing in the heat absorbing cabin inside heat exchanger 35 when cooling is stopped, is sealed still in its condition, and is maintained in a low temperature condition for a while. Operation is performed on a target blowoff temperature from a cooling load in a cabin, and an initial blowoff temperature at cooling operation starting time is anticipated by an initial blowoff temperature anticipating means. Operation is performed on an operation frequency of the compressor 31 by using at least the target blowoff temperature and the initial blowoff temperature as a parameter.  Therefore, cooling operation can be performed without enhancing a compressor frequency more than necessary.
