Title: Refreshing circuit for semiconductor memory
Inventor: KUWABARA SUMIO
IPC: G11C11/406
Filed: 1988-09-21
Abstract: PURPOSE:To permit the action with a low energy consumption without complicating an external circuit by frequency-dividing a refreshing starting signal to generate accompanying a memory access with the settable frequency-dividing ratio and activating a refreshing action with a frequency-dividing output. CONSTITUTION:An internal signal generating circuit 1 inputs a control input signal and outputs control signals phi1 and phi2. A frequency-dividing circuit 2 frequency-divides a signal phi2 to instruct the refreshing start and a control signal phi3, which is the frequency-dividing output, is outputted as a signal for refreshing activation. The frequency-dividing circuit 2 is composed of a variable frequency-dividing and the frequency-dividing ratio is determined by a control signal phi4 from a register 3. The register 3 is composed to be able to set an arbitrary value from an external part. Thus, the number of the times of refresh ing actions is stopped to the necessary minimum without depending on the external number of the times and the low energy consumption can be realized.

Title: Electron microscope
Inventor: KURIYAMA HIROYUKI
IPC: H01J37/26
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To improve the operability of an electron microscope by laying out an operation panel to such a configuration as suitable for an operator's working posture, and applying operability to various operation devices so as to be suitable for the purpose of use thereof. SOLUTION: Each of operation devices of an electron microscope is classified into such a device as frequently operated without any visual recognition at an observation process, and a device not used so frequently at the process. Also, the devices frequently used are arranged in a zone 1 falling on the working radius of forearms around the positions of elbows when an operator places his/her arms on a console in a natural form. Furthermore, the devices not used frequently are classified for every function, and arranged at positions 2 behind forearm working zones as well as easily visible. Thus, an operator can quickly operate each device on the working radius of the forearms around the elbows, without any need of turning his/her eyes thereon during an observation work.  Also, the devices not used so frequently during the work can be recognized by slightly moving his/her eyes from observation surface, and an operation can be made after the proper recognition of the devices.

Title: Image forming device
Inventor: YAMAGUCHI YUKIO
IPC: G03G15/01
Filed: 1996-08-20
Abstract: PROBLEM TO BE SOLVED: To prevent an image from degrading due to not only surface staining but also a backside reflection image by adjusting image density which is formed in a recording medium based on a peak position which has the maximum frequency in three separate areas in a histogram. SOLUTION: A detected output of an optical sensor 36 is inputted in a sampling circuit 40, and the sampling value of its output is inputted in a density partitioning circuit 41. The circuit 41 identifies to which density partition that is preliminarily defined the sampling value belongs. An output of the circuit 40 is inputted in a counting circuit 42 and the sampling value is counted. By the operations of the circuits 41 and 42, a histogram on density distribution of the original is created and stored in a storing means that is provided in the circuit 42. A peak position detecting means 44 divides the histogram stored in the circuit 42 into three density areas according to a boundary value analysis and finds the density partition of the maximum frequency belonging to each density area.  A density adjusting means 45 adjusts image density so that surface staining and a backside reflection image may not be reproduced on recording paper and gives image data to an optical writing unit 6.

Title: Light source
Inventor: HASEGAWA HAYATO
IPC: G02B7/00
Filed: 1990-09-06
Abstract: PURPOSE:To accurately control the quantity of output light by working the surface of a holder counter to a semiconductor light source in black. CONSTITUTION:The surface of a housing recessed part 37 faced to a laser diode 32 as the semiconductor light source mounted on a base plate 31 fixed to a light source holder 30 is worked in black. Therefore, since light generated from the diode 32 is absorbed on the surface of the recessed part 47, light reflected on the surface of the recessed part 47 is not photodetected by a photodetector 36. Namely, the photodetector 36 photodetects only a laser beam L12 radiated by the diode 32 in the direction of the base plate 31, and the output of this photodetector 36 is exactly corresponding to the quantity of output light from the diode 32. Therefore, an operating current I regulated by a driving circuit 70 is exactly corresponding to the desired quantity of output light from the diode 32. Thus, the optical output of the diode 32 is accurately controlled.

Title: Film initial feeding mechanism
Inventor: TANAKA YASUHIKO
IPC: G03B17/42
Filed: 1989-09-14
Abstract: PURPOSE:To miniatuarize a sprocket for film initial feeding by increasing the rotating radius of a film feeding pawl of the sprocket in the range the pawl is engaged with the perforation of a film and reducing the radius in other range. CONSTITUTION:The sprocket 22 is controlled by a cam 24 through pins 22C and 22C with the rotation and in the rotating range that the film carrying claw 22A is engaged with the perforation of the film, the sprocket is shifted from a rotating shaft 20 so as to permit the rotating radius of the film feeding claw 22A to be longest. Therefore, the necessary rotating radius for the film feeding claw 22A to supply the film is ensured. In the rotating range that the film feeding claw 22A is not engaged with the perforation of the film, the sprocket 22 is shifted from the rotating shaft 20 so as to permit the rotating radius of the claw 22A to be short and the necessary space in a camera for the rotation of the sprocket 22 is minimized. Thus, the sprocket for the film initial feeding is miniaturized.
