Title: Alignment
Inventor: HAMAZAKI FUMIYOSHI
IPC: G03F9/00
Filed: 1987-03-20
Abstract: PURPOSE:To improve accuracy of alignment, by measuring the amount of shift of an original plate to a substrate in prescribed regions on the substrate and rejecting abnormal values from the measured ones and performing theta directional alignment of the substrate and next performing alignment of the original plate to the substrate in the respective regions. CONSTITUTION:The amount of position shift of an original plate RT to a substrate WF in prescribed regions on the substrate WF is measured by observing light which transmits a projection optical system LN and is reflected on or diffracted from marks on the substrate WF. Abnormal values are rejected from the measured ones, and theta directional alignment of the substrate WF is performed on the basis of the results of rejection. Thereafter, the alignment of the original plate RT to the substrate WF is performed in their respective regions. When the abnormal values are thus rejected, following alignment is performed on the basis of the measured values with high reliability as a result. Hence, the alignment of the original plate to the substrate can be performed with good accuracy.

Title: Working method for wall of hollow body
Inventor: ITOU SHIGEO
IPC: B23P13/00
Filed: 1980-05-14
Abstract: PURPOSE: To reduce noise and to prevent sticking of molten substances to inner wall by working the wall of a hollow body with liquid contained in the hollow body.  
     CONSTITUTION: Liquid 2 such as water, mineral oil etc. is put in a steel hollow body 1 having rectangular section so that some space is left between the upper wall of the hollow body and the surface of the liquid 2. Then, the upper wall of the hollow body 1 is cut with a plasma arc torch 3 from out side. At this time, molten substances and sparks 4 fall into the liquid 2 and solidify by cooling before sticking to the inner wall of the hollow body 1. The solidified matters are removed easily. Further, vibration generated at the time of cutting is absorbed by the liquid 2 to reduce resonance of the hollow body 1. In case where grinding etc. only is performed without including cutting, reduction of noise can be attained.

Title: Antiskid braking device for automobile
Inventor: HAYASHI TSUTOMU
IPC: B60T8/48
Filed: 1980-05-15
Abstract: PURPOSE: To reduce load on the engine without use of any solenoid operated pump nor batteries by employing an unloader type pump for generation of control oil pressure which shall be driven by the engine.  
     CONSTITUTION: The drive shaft 65 of a pump Ph is driven by the engine through the crank shaft and presses a tappet 78 using an eccentric pin 65a. A plunger 79 reciprocating through the tappet 78 is facing to the inside of the pump chamber 76, and is pressed against the tappet by a spring 82. This pump chamber 76 is connected to an oil tank 30 and an pressure accumulator 31 through a suction valve 86 and a discharge valve 88, respectively. When the pressure in the accumulator attains a certain preset value, the plunger 79 will be held shifted upward by the oil pressure to ensure that only the tappet 78 operates and the pumping action thereby stops. Because the pump is, as mentioned above, of unloader type with which the pump will stop when the oil pressure has risen, the engine is assured to be free from unnecessary load.

Title: Rotary image memory
Inventor: HIRASAWA AKIRA
IPC: G06T3/60
Filed: 1987-03-19
Abstract: PURPOSE:To obtain a rotary image memory which can reduce the packing area of a memory circuit without deteriorating an output video rate, by processing simultaneously (n) pieces of planes out of (n<2>) pieces of planes in a reading mode. CONSTITUTION:In case 16 picture elements on the 6th row of each group array of an original image are read out of a memory circuit 14 in a rotary state 0 deg., an address 5H (H: hexa) is applied to an address converting circuit 15 and an address to be applied to each memory is set at 2H to be applied to the circuit 14 as well as original image memories M1-M8 respectively. In this case, 32 picture elements equivalent to 4 planes of a 0 deg. rotary mode can be read out of the circuit 1 at one time. The picture elements of the 6th row are stored in blocks 3 and 4, i.e., planes 4 and 3 and therefore planes 4 and 3 are validated out of 4 planes. Then desired data is converted into (8+8)-bit parallel signals by data rearranging circuits 12 and 13. These parallel signals are turned again into 16-bit data combined alternately for each bit. This data is converted into serial signals by a P/S converter 16 and outputted.

Title: Surface burnishing apparatus for thin-film magnetic recording medium
Inventor: KOBAYASHI KAZUO
IPC: G11B5/66
Filed: 1984-03-30
Abstract: PURPOSE:To remove only projections without damaging the surface of a thin- film magnetic recording medium by allowing burnishing heads having an alumina ceramic piece containing titanium carbide having a hard and smooth surface to contact in slidable ways onto the surface of a recording medium. CONSTITUTION:When burnishing heads 2 and 3 are moved in slidable ways over the whole surface of a magnetic recording medium 8, a carriage 1 and an arm 4 are connected to a mechanism which moves in slidable ways between the arrows A-A' within a certain angle around a holder 7, and the burnishing heads 2 and 3 are transferred in the radial direction of the magnetic recording medium 8. Therefore, when the carriage 1 and the arm 4 shift the burnishing heads 2 and 3 in the radial direction of the recording medium in the state where the magnetic recording medium 8 is revolved by a rotary mechanism 9, the heads move in slidable ways on the whole surface of the recording medium. Since only the projections on the surface of the recording medium can be removed without damaging the surface of the recording medium and the burnishing heads, the head clash can be effectively prevented.

Abstract: PROBLEM TO BE SOLVED: To provide an electronic keyboard instrument made compact so as to be convenient for transportation and storage. SOLUTION: A low sound side part 6 or a high-pitched sound side part 8 is inverted and placed on top of the high-pitched sound side part 8 or the low-pitched sound side part 6, with the top parts of upright parts 14, 16 mutually adjusted onto a keyboard of the other party. At this time, a groove of a contact protruding member 34 comes in contact with the tip of an opening bar 102 or 112 of the other party, and cushioning material 32 pushes in the keyboard of the other party. Compared to a performing state long in the width direction, an electronic keyboard instrument 2 is miniaturized into half in a width direction so as not to take up much space for storage. In addition, since the keyboards are covered, the electronic keyboard instrument 2 is stored in the protected state of the keyboards.  Even in the case of transporting this electronic keyboard instrument 2 in the state of being bound or packed in a box, this electronic keyboard instrument 2 does not take much space for loading into a vehicle or the like because of being compact, and since the keyboards are pressed by the cushioning material 32, the keyboards and internal dummy action interlocked with the keyboards are not oscillated so as no to cause the damage of internal mechanism such as the dummy action during transportation.

Title: Controller for number of motors
Inventor: AMANO ATSUSHI
IPC: F04B49/06
Filed: 1991-03-28
Abstract: PURPOSE:To precisely control the number of motors with no overshoot even with use of a controller that has the low responsiveness. CONSTITUTION:The number of operating motors of the blowers 1-3, etc., are calculated based on the only process value. At the same time, it i decided based on other related process values whether the actual number of motors should be increased or decreased. If the number of motors should be increased or decreased, the motors are increased or decreased based on the number calculated from the only process value. Thus it is possible to suppress the overshoot that is easily caused when the number of motors is controlled based on the process value having the comparatively high responsiveness in system having especially low responsiveness. Then the stable control of a system is attained.
