Title: Image forming device
Inventor: WATANABE AKIRA
IPC: G03G15/08
Filed: 1989-06-12
Abstract: PURPOSE:To prevent developer from splashing by forming electric field having a polarity opposite to the polarity at the time of developing between a developing device and an electrode member provided along the moving path of the developing device which advances and retreats. CONSTITUTION:The electric field having the polarity opposite to that at the time of developing is formed between the developing device 14 and the electrode members 18a and 18b provided along the moving path of the developing device 14 which advances and retreats. Therefore, the electric field having the polarity opposite to the charge of the developer having the opposite polarity to reverse development at the time of developing in a developing device works in front of and at the rear of the developing part corresponding to a latent image carrier 1 in the developer carrier 15 of the developing device 14, so that electrostatic restricting force between the developer and the developer carrier 15 is strengthend. Thus, the developer is prevented from splashing even when the developer carrier is driven to be rotated other than at the time of developing.

Title: Operating oil cooling structure for industrial vehicle
Inventor: KUSHIOKA KATSUHIKO
IPC: G12B15/00
Filed: 1994-06-29
Abstract: PURPOSE:To improve the heat radiating effect of the operating oil so as to improve the operating oil cooling performance by forming an oil chamber, in which the operating oil is flown, in a fender provided in a car body so as to cover a part of a wheel, and providing a control valve, an oil tank and a pump in a hydraulic circuit communicated with this oil chamber.

Patent JP-H0233410-A (JP)
Title: Shroud device for engine cooling fan
Inventor: JIYON REINORUZU SABUEEJI
IPC: F01P5/06
Filed: 1989-06-12
Abstract: PURPOSE: To inhibit the recirculation of the air discharged by a fan to an inlet so as to improve efficiency and reduce noise by affixing a rotation ring-shaped shroud in the form of a bellmouth to a blade tip of a cooling fan to form a facing state for generating an air vortex. CONSTITUTION: The air discharged by a fan 48 when driven by a motor 52 has a radial component A, which partially blocks a clearance passage 70 at the discharge side of the fan 48. This blocking reduces the amount of recirculation air flow, so that the fan 48 can moves air at a higher efficiency. Further, since the recirculation amount of the air returning to a bellmouth 44 is reduced and a turbulence generated due to the recirculation is reduced, the noise generated when actuating the fan 48 is reduced. In addition, the shroud construction is such formed that a forward air block is formed that further inhibits the flow of recirculation air for a wide range of fan operating points which materially extends the limited range of blockage provided by an extending ejector 38 and a rotatable shroud 46.  Furthermore, a vortex 96 generated due to a vortex chamber 78 acts as an air ring to block a recirculation air path, thus improving the fan efficiency and flow distribution.

Title: Loudspeaker
Inventor: SENOO FUTOSHI
IPC: H03G5/02
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To ensure sound fidelity at the time of small sound volume and to obtain sufficient sound articulation at the time of large volume. SOLUTION: A voice signal outputted by a microphone 2 is inputted through a pre-amplifier 13 to a frequency characteristic varying circuit 14. When the level of the voice signal is large, that is, at the time of large sound volume, this frequency characteristic varying circuit 14 reduces low-pass components which are less than frequencies fL and high pass components more than frequencies fH, and this is transmitted via a power amplifier 15 to a loudspeaker 3. Thus, the low-pass components and the high-pass components are reduced at the time of large volume such that the distortion of each component can be reduced, and sufficient sound articulation can be obtained. On the other hand, the frequency characteristic varying circuit 14 outputs the inputted voice signal as it is. Therefore, a sound is reproduced faithfully.

Title: Electronic still camera
Inventor: HORI MASASHI
IPC: H04N5/225
Filed: 1990-06-07
Abstract: PURPOSE:To improve the voice recording operability by selecting the microphones turned toward a subject and a photographer for input of them to a voice processing circuit and recording the voices to a recording medium in a simultaneous recording mode with or an independent recording mode of the selected photography. CONSTITUTION:When a selection means 15 switched to AUTO together with a simultaneous recording mode kept, the voices can be recorded to a recording medium 10 simultaneously with photography by a built-in microphone 1. In an after-recording or re-recording mode after photography, the simultaneous recording mode of the means 15 is canceled. That is, an independent recording mode is selected. As a result, the voices can be optionally recorded to the medium 10 by a built-in microphone 2 turned toward a photographer regardless of the photography state. Thus it is possible to omit the troublesome operations to change the direction of a camera main body at each time. Then the recording methods and the microphones can be selected just with operations of the means 15.

Title: Fan out regulating system
Inventor: UBUKATA MASARU
IPC: G06F17/50
Filed: 1988-06-15
Abstract: PURPOSE:To regulate fan out for all designated signal names with the minimum buffer elements by generating the combination of suitable buffers and inserting it between an output terminal and an input terminal when a circuit having the output terminal is decided not to have driving ability. CONSTITUTION:A clock signal name extracting means 15 extracts the clock signal name to regulate the fan out from circuit information. From the fan in information and fan out information of the signal system terminal group of the signal name extracted by a clock signal name extracting means 15, a fan out regulating means 16 checks whether or not the driving ability of the output terminal to be the starting point of the signal system is sufficient. When it is insufficient, a buffer circuit element having the sufficient fan out is generated, and the buffer elements are successively inserted from the output side of the signal system to the input side in the sequence from the element at a larger fan out value. Thus, since the regulating buffer elements can be reduced, the fan out can be regulated for the signal system of the all signal names.
