Title: Diversity system and its transmission equipment and reception equipment
Inventor: HIGUCHI YUJI
IPC: H04J11/00
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To discriminate whether the reception qualities in plural reception systems are good or not by a small-scale circuit in a diversity system adopting an OFDM system. SOLUTION: In a transmission equipment, a known PN signal is multiplexed with a specific carrier. A reception equipment extracts the specific carrier by band pass filters 13, 14, 23, and 24 and demodulates it by FETs 17, 18, 27, and 28 of small points. This demodulation output and a PN signal of the output of a PN signal generation circuit 34 are compared with each other by comparison circuits 19 and 29 to obtain the number of errors. A signal of a system where the number of errors is small is selected by a switching circuit 32 in accordance with this number of errors, thus performing demodulation.

IPC: B65H57/24
Filed: 1981-01-28
Abstract: PURPOSE:To obtain a long life thread guide with excellent wear resistance never causing disconnection or nap in a thread, by constituting the thread guide from sintered material of silicon carbide quality in which thermal conductivity, specific resistance and crystal particle diameter are set to a value respectively in a specific range. CONSTITUTION:A thread guide for guiding a natural fiber thread or synthetic fiber thread and the like is constituted by silicon carbide sintered material with thermal conductivity not less than 0.10 (cal.cm/cm<2>.sec. deg.C), specific resistance not more than 10<7>(OMEGA.cm) and crystal particle diameter less than 20mu. In this case, the above described sintered material is manufactured by the conventionally known method, in which a dispersion object of uniform quality, consisting of carbon organic material like, for instance, alpha silicon carbide powder, is formed and this formed material is sintered at high temperature in the inactive atmosphere. In this way, the thread, even if contacted running at high speed through out a long period, never causes nap or disconnection to obtain the thread guide of long life.

Filed: 1987-01-23
Abstract: PURPOSE:To shorten an exposure time, by making a reciprocating motion of a light source in the specific condition in the case of forming a black matrix through a shadow mask with slot-shaped opening parts. CONSTITUTION:A light profile 3 is obtained with rays of light through a slot from a linear light source 1 opening of a shadow mask 2 and a light profile 3' is obtained through an adjoining slot of the shadow mask.

Title: Stamping printer for foil
Inventor: YAMAMOTO MASAO
IPC: B41F17/00
Filed: 1981-01-30
Abstract: PURPOSE:To obtain the title apparatus wherein stamping printing can be conducted on the surfaces of a plurality of long articles in one process by providing a stamping film supporting mechanism and a stamping roll mechanism having specially-formed heat-resisting rolls in a conveying passage of an article conveying block. CONSTITUTION:Compressed fluid from the direction of an arrow X reaches the lower parts of hydropneumatic cylinders 36-38 through an air pilot type pressure adjusting valve 57 and the position (a) of a solenoid valve 55. When the heat-resisting rolls 18-20 for stamping printing come to the corner part of an article to be printed, the solenoid valve 55 is switched from the position (a) to a position (d), the fluid moves a piston upward and a roll supporting arm 31 increases the pressing force of a roll 25. When the surface to be printed of the article has a convex form and is given an upward tilt, the roll moves upward with the surface to be printed and thereby the fluid pressure below the piston is increased. However, the fluid gets away from the pressure adjusting valve 57 and thus the pressure is kept fixed. On the other hand, when the surface has a concave form and is given a downward tilt, the lowered fluid pressure is replenished and thus the pressure is kept fixed likewise.

IPC: G09G3/36
Filed: 1995-01-30
Abstract: PURPOSE:To make display ample with three-dimensional feel, perspective feel and shading feel having depth by providing respective display layers with priority functions. CONSTITUTION:Blocks 2, 3 have functions to successively read on/off information from a display memory 8 of the addresses corresponding to the respective layers, to latch this information, to convert the display memory data to the data receivable by an LCD module 9 and to successively deliver the data. The output of the block 2 is regulated by the signal FL1 which is generated by an AND GATE 4. On the other hand, the output of the block 3 is regulated by the signal FL2 which is generated by an AND gate 5 and is simultaneously regulated by the output of a NAND gate 7 as well which imparts the display priority order between the layers. Then, the output of the gate 7 attains '0' in the case that the signal for controlling priorityof the layer is S=1 at the timing at which the information of dot lighting is emitted from the block 2 and, therefore, the display information of the layer L2 emitted from the block 3 is disregarded by the gate 5 which receives the output of the gate 7 as its input.

The side surfaces of the adjacent core back iron core portions 3 are aligned after winding the stator coil 5 of the centralized winding to surround the teeth iron core portion 2. Here, since the both side surfaces of the core back iron core portions 3 are tapered, the dividing surfaces of the adjacent core back iron core portions 3 can be aligned in the zero-gap condition as much as possible. Next, a force is applied to the cutout portion 7 of the core back iron core portion 3 to fix the core back iron core portion 3 with inclination to the sloping part 8 of the adjacent core back iron core portion 3 to form a stator 1.

Title: Buffer circuit
Inventor: SONEDA MITSUO
IPC: H03K5/02
Filed: 1984-01-30
Abstract: PURPOSE:To improve frequency characteristics and to attain load drive with high gain by actuating the FET of an input source follower stage at a saturated area. CONSTITUTION:MOSFETs-M1 and M2 form an input source follower stage and an output source follower stage respectively. A FET-M1 works by using the source voltage of a FET-M2 as the drain voltage. In this case, the FET-M1 works at a saturated area as long as the value obtaned by subtracting the source voltage of the FET-M2 from the gate voltage of the FET-M1 is smaller than the threshold voltage of the FET-M1. Therefore, the current value I0 of a current source 2 is set at a prescribed level. Thus the FET-M1 works at the saturated area, and each gate voltage is held approximately at the same potential as each source voltage. Then the gate/drain capacity of the FET-M1 is reduced. This improves the frequency characteristics.
