Title: Cooling device of v-belt transmission mechanism
Inventor: KURATA KOJI
IPC: F16H57/04
Filed: 1990-06-29
Abstract: PURPOSE:To improve the efficiency of cooling a starting clutch and air circulation by forming an enlarged diameter extension portion extending in the direction of a movable face of a driven V-pulley on a clutch squeak preventing clutch housing plate of a starting clutch. CONSTITUTION:In a centrifugal shoe type starting clutch, when the rotating speed is low, a centrifugal shoe 33 slides in a half-clutch state and a clutch housing 34 is vibrated to generate the so-called clutch squeak. Accordingly, the outer peripheral surface is covered with a clutch housing plate 35 to damp the vibration. One end of the clutch housing plate 35 is extended in the direction of a movable face 20a in such a manner as to be gradually increased in diameter to form an extension portion 35a. During high speed operation, the movable face 20a is moved to enter the clutch housing place 35. Cooling air circulated from an introduction port 26 to an outlet 27 is introduced much more into the clutch housing 34 by the extension portion 35a so as to cool a starting clutch 22 efficiently.

Title: Encoding transmission equipment for color picture information
Inventor: CHIBA KAZUHIRO
IPC: H04N1/417
Filed: 1989-06-30
Abstract: PURPOSE:To transmit satisfactory picture information by converting picture information at every picture element into achromatic color information and color information, identifying a conversion state, generating identification information and transmitting identification information so that a transmission code error should not extend to it. CONSTITUTION:A converter 1 sets a minimum value among three original color information R, G and B to be achromatic color information K in input color picture information at every picture element, and converts picture information into color information (r), (g) and (b) calculated by achromatic color information K and three original color information R, G and B. Achromatic color information K, and color information (r), (g) and (b), both of which are generated in the converter 1, are encoded and they pass through a transmission line 105, whereby they are decoded. Then, they are inputted to an invertor 6 so that subsequent information should not be influenced even if the code error occurs. The invertor 6 on a reception-side restores original color picture information R', G' and B' with an action opposite to the converter 1 from achromatic color information K' and color information r', g' an b'. Thus, appropriate color picture information without a color blur can be transmitted.

Title: Device and method for form rolling of gear
Inventor: KATO KEIJI
IPC: B21H5/00
Filed: 1996-07-01
Abstract: PROBLEM TO BE SOLVED: To form a tooth form with high precision. SOLUTION: The tooth form is formed on a work W by using three dies, pinion type dies 17a to 17c. Consequently, being different from a form rolling device (form rolling method) using one or two pinion type die(s), for instance, even when the work W is about to shift against the pinion type dies 17a and 17b, since the remainder pinion type die 17c is present in the shift direction, the shift of the work W is suppressed. Consequently, the gear with a highly precise tooth form is possible. Also, the device is constituted so that three pinion type dies 17a to 17c are arranged, and the respective dies 17a to 17c are synchronized, and they are allowed to come into contact with the work W. That is, only making respective pinion type dies 17a to 17c come into contact with the work W, since the center position of the work W is set, the centering working of the work W is unnecessary.

Title: Undercolor removal method and device
Inventor: SHIMIZU TOSHIHIRO
IPC: H04N1/46
Filed: 1981-10-26
Abstract: PURPOSE:To make undercolor removal possible in a high ratio without making the hue achromatic, by controlling the undercolor removal quantity on the basis of the ratio of the primary color signal of each color to a black ink quantity signal or the like. CONSTITUTION:Three primary color signals from an original picture 1 due to a reading part 10 and a masking correcting circuit 20 are inputted to a black color calculating part 40 of an undercolor removing part 30, and a black ink quantity signal is formed through the calculating part 40 and a masking circuit 41. A ratio of each primary color  signal to the black ink quantity signal is determined in a ratio calculating part 60, and removal black ink quantity calculating parts 45Y, 45M, and 45C of respective colors are controlled through undercolor removal controlling parts 70Y, 70M, and 70C in accordance with his ratio. Consequently, the undercolor removal considering the hue is performed in accordance with the ratio of each primary color signal to the black ink quantity signal by operational amplifiers 48Y, 48M, and 48C, and thus, undercolor removal is performed in a high ratio without making the hue achromatic, and transfer of inks is improved to economize in quantities of primary color inks. The similar result is obtained when the control based on the ratio of the black color signal to an average value of respective primary color signals is performed.

Title: Rolling mill
Inventor: NIHEI MITSUO
IPC: B21B27/00
Filed: 1983-09-19
Abstract: PURPOSE:To eliminate perfectly the mark transferred to a rolling material from the end parts of segmental backup rolls by using a high wear-resistant material for constructing backup rolls which are in direct contact with work rolls among backup rolls. CONSTITUTION:A six-high mill is used for rolling, which consists of a pair of upper and lower work rolls 1, intermediate rolls 2 which are in contact with these work rolls 1 respectively, and backup rolls 3 which are in contact with the rolls 2 and support a rolling load. Backup rolls 4 which support the small diametral work rolls 1 while being in direct contact with them are arranged at both sides of the rolls 1 respectively. A roll constituted of sintered silicon carbide body excellent in wear-resistant property is used for the roll 4. In this way, a mark at the end part of segmental roll is never transferred to a rolling material 10 through the roll 4, because the lubricity between the roll 4 and a bearing 5 is excellent and the hardness of roll 4 is large as compared with that of the bearing 5.

Title: Thin film transformer and magnetic head equipped with the transformer
Inventor: BUIKUTAA TSUIIREN
IPC: G11B5/31
Filed: 1988-07-08
Abstract: PURPOSE: To reduce the dimensions by forming a magnetic yoke with a first and second permeable layers from among layers formed by the thin-film technology, extending first and second windings made from a conductive layer into the yoke, and forming a superconductor layer between these windings and yoke. CONSTITUTION: The transformer comprises layers formed by the thin-film technology. Among them first and second permeable layers 3, 5 cooperate to form a magnetic yoke into which first and second windings 13, 15 each made of a conductive layer extending, and a superconductor layer 21 is formed between these windings and yoke. Thus the Meissner effect prevents a magnetic short- circuit current from occurring between the parts of the permeable layers 3, 5 at both sides of the superconductor layer 21 and hence a great potential loss, thereby ensuring high efficiency and reducing of the dimensions.

Title: Bypassing system for loop network
Inventor: HAYAMA HIROYUKI
IPC: H04L12/42
Filed: 1988-07-12
Abstract: PURPOSE:To prevent the whole of a slow network from going down by setting the bypassing state of the node of the slow network when it is detected that no frame header signal arrives over a constant time. CONSTITUTION:When it is detected that no transmission header signal 72 is received over the constant time, the node 51 of a fast network sends a command to a bypass control circuit 74, and makes the bypass control circuit 74 select a mode to transmit data from a preceding stage as it is. In other words, the bypass control circuit 74 is switched from the position of continuous line to that of dotted line, which sets the node 51 of the slow network at the bypassing state. In such a way, it is possible to obtain a system with high reliability without generating the down of the whole of the slow network even when the node of one slow network goes down.

Title: Sensitivity switching circuit for radio receiver
Inventor: ISHII HISAO
IPC: H03G3/20
Filed: 1990-06-29
Abstract: PURPOSE:To surely attenuate the signal by applying amplification and tuning processing to a reception RF signal so as to extract a signal with a prescribed level and frequency, applying mixing and detection, etc., to the signal, reproducing a desired broadcast and arranging a level attenuation circuit switching the signal attenuation to the stages following an AGC circuit. CONSTITUTION:In the case of the automatic channel selection, the frequency of a signal extracted from the reception RF signal is sequentially changed. In this case, the signal level at the output of an IF amplifier circuit 6 is detected and when the level is a prescribed threshold level or above, the frequency revision is stopped at the frequency corresponding to the level to select the broadcast station. On the other hand, when the level is a prescribed threshold level or below, the frequency is revised to a succeeding frequency and the operation is repeated. The ON/OFF of an attenuator 12 is implemented by a Lo/DX changeover switch 10. In the case of the Lo mode, the input itself to a mixer 5 is attenuated, the threshold level for the channel selection to the reception RF signal is substantially increased and only the reception signal of a broadcast station equivalent to a strong radio wave intensity is selected.

Filed: 1983-09-20
Abstract: PURPOSE:To improve the reading probability by dividing the light given from a light source into plural beams with dividing means such as a half mirror, a beam splitter, etc. and scanning each beam by a hologram disk. CONSTITUTION:The light given from a light source 12 is divided into plural beams by a half mirror or a beam splitter 13 and scanned by a hologram disk 19. These scan beams 22 and 22' are modulated by a bar code 24 and reflected. The reflected beams 23 and 23' pass again through the hologram 19 to be focused and reflected by perforated mirrors 15 and 16 to be detected by photodetectors 17 and 18 respectively. Therefore plural scan beams exist in a space above a window 21. This increases the number of scan beams crossing the bar codes and improves the reading probability.
