Title: Light source unit for endoscope
Inventor: NISHIMURA SHIGERU
IPC: H04N5/335
Filed: 1989-11-09
Abstract: PURPOSE:To adjust the wavelength characteristics of illumination light according to purposes by making the illumination light incident on a light guide through respective light wavelength selective filter areas of R, G, and B in order. CONSTITUTION:A color filter disk 11 is fitted on a rotary shaft 12, which is coupled with a motor 13; and a rotary shaft 14 coupled with a color filter disk 10 is a hollow shaft, where the rotary shaft 12 is run. When the rotary shaft 12 is driven to rotate while energized as shown by an arrow P, the rotary shaft 14 rotates following up the rotary shaft and the color filter disks 10 and 11 are rotated synchronously. When the rotary shaft 14 is displaced as shown by an arrow Q, only the rotary shaft 12 rotates and the color filter disk 11 is rotated independently to rotate. The color filter disks 10 and 11 are sectioned into three areas at 120 deg.. Consequently, the illumination light in a desired wavelength area is used for lighting and the sensitivity characteristics of a film and the wavelength of a light source lamp can be corrected.

Title: Recorder for scanning and recording
Inventor: ARAI KOJI
IPC: B41J19/18
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To accurately conduct a recording operation at a low cost according to a position detection signal asynchronously generated by reading a memory in synchronization of an output of a memory control means with an output of a position detecting means, and driving a recording means in response to outputs of an image memory and a record control means. SOLUTION: When a CPU 117 rotates a motor 115, a printer carriage 102 starts moving along an encoder scale 103, and outputs position detection information from an encoder head 104. In this case, control of an effective image section signal generating means 108 by the CPU 117 is conducted asynchronously with control of a motor control means 116, and timing of generating an effective image section signal VE becomes asynchronous with timing of a generating the position detection information from the head. Thus, the asynchronously generated position detection information ENCP is synchronized with a memory operating cycle generated in synchronization with the signal VE by a synchronizing means 111.

Filed: 1987-11-18
Abstract: PURPOSE:To simplify the construction and offer the arbitrary flow control characteristics by giving the pressure loss preventing function to a valve which has the flow drop characteristics, that is, executes the drooping function. CONSTITUTION:When the revolution speed of a pump 6 driven by an automobile engine is increased gradually, a spool valve 3 is moved to the right due to pressure difference between the front and the rear position of each of a fixed orifice 4c and other orifices 4d and 4e. When a flow return passage 7 is communicated with a supply passage 5, excess of flow is returned so that the quantity of fluid fed to a power steering device P.S is kept constant. A sleeve 12 is moved to the left due to the pressure difference between the front and the rear position of a limited flow passage 16. As a result, the sleeve 12 has each of the orifices 4d and 4e reduce in bore so that the pressure difference between the front and the rear position of each of the orifices 4c-4e is increased, on account of which the spool valve 3 is moved to the right to increase the quantity of return flow.
