Title: Laser light arranging device
Inventor: KITAJIMA NOBUO
IPC: G03G15/04
Filed: 1981-09-12
Abstract: PURPOSE:To condense laser lights closely with a simple optical system and to use them effectively for a high-speed printer or the like, by reflecting totally plural parallel laser lights on reflective films of slope parts of a transparent optical material so that they are close to one another. CONSTITUTION:In an arranging optical member 10 using an optical glass, apexes of an incidence part 13 and an emission part 15 whose sections are approximately triangular are connected to each other by a flat intermediate part 14, and all of the surface except end faces 11 and 12 is coated with a metallic reflective film 16. When three parallel laser lights 1a-1c are made incident to the end face 11, the light 1b goes straightly to become a light 1b'. Lights 1a and 1c are reflrected totally in the intermediate part 14 repeatedly after being reflected totally on the reflective film 16 of slope parts 13a and 13b and are reflected totally on the reflective film 16 of slope parts 15a and 15b and are emitted as  lights 1a' and 1c' from the end face 12 without overlapping the light 1b'. Thus,  three lights are condensed closely to one another and are used effectively for a high-speed printer or the like.

Title: Picture coding system
Inventor: ONO FUMITAKA
IPC: H04N7/32
Filed: 1978-11-21
Abstract: PURPOSE: To increase the coding efficiency by carrying out the coding with notice given to the correlation of the approximate picture elements of the picture containing the intermediate tone.  
     CONSTITUTION: The picture signal is turned to the ternary signal which is converted to, for example, three levels of 0∼2, and this series is made to be the subject for coding. The state of the notice signal is decided by the preceding signal, and signals 0∼2 in each state are selected in the order of the higher emergence rate to decide the 1st∼3rd predictive value. Then the predictive conversion is carried out first at the transmission side; while the reverse conversion is given at the reception side. The comparison is given between the actual signal value and the predictive value to the 3rd and 2nd predictive value in that order. As a result, predictive conversion signals Y 1  and Y 2  become 00, 01 and 10 when they are equal to the 1st, 2nd and 3rd predictive value each, but 0 of Y 2  is omitted. Then the signal belonging to the S-series in which 1 is hard to emerge is turned to mode signal 1; while the signal belonging to the W-series in which 1 is easy to emerge is turned to mode signal 2. Thus the predictive conversion signals are allotted to the series to produce the separation series identical to the mode number. And the high-efficiency coding is secured with use of the code decided to each mode.

Title: Powder containing 2h type silicon carbide and its preparation
Inventor: KURAMOTO NOBUYUKI
IPC: C01B31/36
Filed: 1981-09-16
Abstract: PURPOSE:A powder mixture of silicon oxide and carbon is heated in the presence of aluminum or an aluminum compound in a nitrogen atmosphere at a specific temperature to prepare a silicon carbide powder with a high content of 2H type silicon carbide on an industrial scale. CONSTITUTION:The reaction between silicon oxide and powdery carbon is conducted in the presence of aluminum or an aluminum compound in nitrogen atmosphere or a nonoxidative atmosphere containing the same at a temperature higher than 1,550 deg.C. Thus, the resultant silicon carbide includes more than  40vol% of 2H type and less than 3wt% of N type. The absence of aluminum or an aluminum compound in the reaction system results in less than 40wt% 2H- type silicon carbide. The amount of the nitrogen gas in the atmosphere is at least required to be that corresponding to the nitrogen content in the silicon carbide product, however, an excessive amount of nitrogen should be avoided, because it becomes one of the causes of silicon nitride formation. The reaction temperature is required to be higher than 1,550 deg.C, because the objective silicon carbide is not formed at about 1,500 deg.C at which conventional SiC exists stably.

Title: Differential driving unit in crawler type working vehicle
Inventor: SATOJI HISAYUKI
IPC: F16H48/38
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To make a turn at any radius or turning speed, allowing smooth switching of turns. SOLUTION: When a swash plate of a variable volume pump 25 of a turning HST is inclined in the normal rotation side, a turning HST motor 27 rotates normally so that a left crawler driving shaft 12L rotates in the same direction as a right crawler driving shaft 12R. In this case, since the number of revolutions of the left crawler driving shaft 12L is less than that of the right crawler driving shaft 12R, the left crawler travels slower than the right one. This is a mild turn in which the machine body gently turns to the left. When the swash plate of the variable volume pump 25 of the turning HST is inclined further, the number of revolutions of the turning HST motor 27 decreases in proportion to the inclined angle, until it becomes zero. At this phase, the machine body turning is shifted to a turn using the left crawler as a pivot, a brake turn.  When the swash plate of the variable volume pump 25 of the turning HST is further inclined, the swash plate of the variable volume pump 25 of the turning HST is inclined to the reverse rotation side, the turning HST motor 27 rotates in reverse, and the number of revolution increases in proportion to the inclined angle. At this phase, the machine body turning is shifted to a turn in which left and right crawlers are turned in opposite directions, a spin turn.

Title: Beam current control circuit
Inventor: TSUCHIYA MICHITOSHI
IPC: H04N9/24
Filed: 1988-06-13
Abstract: PURPOSE:To prevent cut-off and to keep the luminance level constant by detecting the fluctuation of a high voltage or a focus voltage and controlling a cathode voltage or the 1st grid voltage so as to compensate the fluctuation of the cut-off voltage caused by the fluctuation of the high voltage or the focus voltage. CONSTITUTION:A cut-off voltage EKCO is decided depending on the high voltage or the focus voltage given to a 3rd grid G3. The fluctuation of the high voltage or the focus voltage is detected and a voltage EK of the cathode K or the voltage EC1 of a 1st grid G1 is moved in response to the fluctuation of the high voltage or the focus voltage to compensate the fluctuation of the cut-off voltage due to the fluctuation of the high voltage or the focus voltage. Thus, when the color picture tube of the beam index system is realized by using a unipotential triode type electron gun, it is prevented that the beam current is cut off by high voltage fluctuation and the change in the luminance level is reduced.

Abstract: PURPOSE:To suppress the generation of a crack of a ferromagnetic metallic film near a cut surface by making the peripheral velocity of the cutting edge of a cutter slightly faster than the travel velocity of a magnetic recording medium, and cutting the magnetic recording medium while stretching it in the travel direction with specific tension.

Title: Individual selective calling receiver
Inventor: KATADA NOBUYUKI
IPC: G08B5/22
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To display information other than characters from a received message by discriminating whether message data are character information or other image information based on individual selective calling number information and displaying the data as the character information or the image information without fixing the limit of a kind of characters to be displayed. SOLUTION: Whether message data are character information or other image information is discriminated based on individual selective calling number information and the data are displayed as the character information or the image information. That is, in the case that a decoder CPU 6 detects its own call number in this receiver and that plural call numbers are registered, a call number discrimination section 9 discriminates whether or not the receiver is called by a graphic message receiving call number. Then the decoder CPU 6 stores a message in succession to the call number to a RAM 7 as a text message or a graphics message based on the discrimination result. The stored message is displayed on an LCD 11 by depressing a switch 5.
