Title: Illuminator for mtf measuring apparatus
Inventor: IZUMIDA YUTAKA
IPC: G01M11/02
Filed: 1992-07-24
Abstract: PURPOSE:To separately regulate light quantities on an axis and out of axis and to stably measure it by dividing an array of fiber condensing side constituents to the axis and out of axis in the case of measuring am MTF having a light source, a lens and the fiber. CONSTITUTION:A light to be radiated from a light source 1 is condensed to a certain point via a condensing lens 3. An end face 5a of a fiber 5 is mounted near its focus thereby to efficiently transmit the light of the source 1. Since a light quantity to be condensed to the face 5a is regulated by a diaphragm 2, light quantities to be input to a plurality of solid stage image sensors 9 can be simultaneously regulated. The faces 5a is divided into ranges on an axis and out of axis, and since a part 5b of the range on the axis is shielded by a dimming mechanism 4, only the light quantity on the axis can be altered without altering the light quantity out of axis. Accordingly, outputs of the sensors 9 on the axis and out of axis can be suitably held by the diaphragm 2 and the mechanism 4, and an irregularity in the light quantities from a chart plate 9 can be suppressed.

Title: Cache memory snooping system
Inventor: TSUBOI AKIHIKO
IPC: G06F12/12
Filed: 1990-08-20
Abstract: PURPOSE:To prevent the performance drop of a host bus by providing a snooping signal generating means and an address holding means which holds an address on a system bus and outputs a snooping address together with the snooping signal to a cache. CONSTITUTION:A caching area discriminating means 9 monitors a system bus 12 and, only when a caching area is accessed, gives a snooping permission to a snooping timing generating means 8 by activating a snooping permit signal 15. The means 8 generates a snooping signal 13 and, at the same time, instructs an address holding means 7 to give a snooping address to a cache by using a bus 14 by activating a signal 16. No snooping is performed to areas which are not subject to caching. Therefore, a performance drop avoiding effect can be obtained to a host bus 11.

Title: Reference signal separation device
Inventor: NAKAYAMA TADANORI
IPC: G11B15/467
Filed: 1989-08-25
Abstract: PURPOSE:To accurately separate a reference signal from a reproduction control signal by giving numbers to respective half cycles of a control signal, separating the reference signal in accordance with the numbers and switching a count direction by means of the traveling direction of a tape. CONSTITUTION:A signal f1 showing the traveling direction of the video tape is inputted to an input terminal 101. When the video tape travels in a positive direction and the reproduction control signal a1 is inputted to the input terminal 101, a multiplication means 102 detects the duty of a signal a1, and outputs a pulse when the duty comes to a prescribed value. An up/down counter means 104 is preset to '0' by the pulse and it up-counts by the output signal of the circuit 102. When the count value of the means 104 shows the prescribed value in a first decoding means 105, a frame signal is outputted to a terminal 107. When the count value of the means 104 shows the prescribed value in a second decoding means 106, a color frame signal is outputted to a terminal 108. When the traveling direction of the tape is a negative direction, the means 104 down- counts and executes the same action.

Abstract: PROBLEM TO BE SOLVED: To suppress the increase in position detecting error when DGPS information cannot be received, or the influence of multi-path is received by controlling the filter intensity of a Kalman filter according to the input state of DGPS information. SOLUTION: A GPS receiver constituting an on-vehicle navigation device is provided with a control part 37 for correcting a detected position by use of DGPS information multiplexed to FM broadcast, and a Kalman filter 37a for estimating the position information within the control part 37, which is realized by software, has a filter intensity settable to two high and low stages. For example, the filter intensity of the Kalman filter 37a is set to 'high' in the initial state, and when the DGPS information is inputted to the control part 37, the filter intensity is set to 'low' so as to increase the reducing speed of error. When a predetermined time for making the error to a minimum value was passed, the filter intensity is set to 'high' until the following DGPS information is inputted to decrease the increasing speed of error.

Title: Manufacturing die for forged part with ultrathin fin and manufacture of forged part using such die
Inventor: MARUMO TAKAKAZU
IPC: B21J5/02
Filed: 1988-09-01
Abstract: PURPOSE:To directly manufacture a forged part of an impeller constituting member, etc. having ultrathin wall thickness by fitting a cylindrical die body to a shrinkage fitting ring by shrinkage fitting. CONSTITUTION:A stock A is placed on the upper end face of a base part forming projecting die 31 of a die 1, and brought to striking downward by a forging die punch 4. As a result, a part of the stock A flows into a forming clearance 32 and a forming recessed part 33, and formed to a forged part with a fin. At the time of such forging, a pressure difference of the stock which flows into the forming clearance 32 tends to generate wide or narrow width in each forming clearance, but uniform pressure in the axial direction which a die body 3 receives from a shrinkage fitting ring 2 in this periphery suppresses the inflow pressure difference of the stock A and works to as to keep each forming clearance roughly constant. Accordingly, even if width of the forming clearance is set to the minimum, it is maintained constant through the forging process, and a obtained fin gets ultrathin thickness with contact wall thickness.

IPC: H04N11/04
Filed: 1999-08-03
Abstract: PROBLEM TO BE SOLVED: To obtain high image quality in spite of a small number of colors by generating a limited color image whose number of colors in use is limited from an original image, converting the limited color image into an image of a pallet color form consisting of a color pallet and a color number, generating a limited color image of a plurality of layers with different number of colors in use and encoding the image of a medium layer. SOLUTION: Original image data consist of R, G, B data with 256-gradation each in 24-bits per pixel. The subtractive color processing such as the median cut method is employed to limit number of colors in use into, e.g. 256 colors and color numbers of 0-255 are given to the 256 colors to obtain image data of a pallet color form in 8-bits per pixel. N-layers of limited color images whose number of colors in use differs from each other are generated, the original image is selected as the (N+1)-th layer, and the k-th layer image (2<=k<=N+1) is encoded with no distortion while decreasing the redundancy among the layers. The image data are efficiently compressed by utilizing the similarity of colors of color pallets of the adjacent layers.
