Filed: 1982-06-05
Abstract: PURPOSE:To attain the input of a formula after memory overflow, by operating a formula inputted before the memory overflow, storing it in a key memory and clearing data after operation. CONSTITUTION:Let the storage capacity of the key memory 14 be for 50 keys' share in terms of the number of times of key operations. In inputting a long fornula exceeding this limit, the types of the operation key are discriminated at a control section 11 from an output of a key input section 2 and a required step processing is done afterward. The number of times of key operations is stored in an A register in an operation register, and an operation section 13 discriminates whether or not the data in the A register is >=51 or not. If the section 13 discriminates that it is >=51 at the end of a key input, a flag is set, and the data is read out and operated at the operation section 13 from the head of the key memory. Thus, the content of the A register is decreased, the content of the A register is discriminated by the operation section 13 again and when it is discriminated the content is <=51, the data of the formula read out so far is cleared and the remaining data are all shifted right. Further, the successive operation processing is done.

Title: Remote solar meter
Inventor: IKEDA HIROSHI
IPC: G01W1/12
Filed: 1978-08-11
Abstract: PURPOSE: To highly accurately measure the time from sunrise to sunset by using a rotating reflecting mirror and a photoelectric element thereby to effect strict correspondence between the threshold value of a solar meter and the quantity of radiation of direct arrival.  
     CONSTITUTION: A main body is arranged to have its main axis in parallel with the axis of the earth. When a reflecting mirror 4 is turned, the photocurrent is generated in a photoelectric element 9 in accordance with the intensity of the incident light coming from the sky. The component scattered in the sky and the directly incident light are partially removed from the photocurrent obtained by the element 9. The number of pulses which are generated by the directly incident solar light exceeding the threshold value is measured. The number of the pulses counted during the observation is multiplied with the rotating period of the mirror 4 so that the time from sunrise to sunset during the observation can be obtained. Moreover, the reflecting mirror 4 exhibits the characteristics substantially independent of the position of the sun so that the influences from the light scattered in the sky can be reduced. As a result, the relationship between the threshold value of the solar meter and the quantity of radiation of direct arrival can be made to strictly correspond so that the accuracy can be enhanced.

Title: Manufacture of disc brake pad
Inventor: IWATA KOICHI
IPC: F16D69/04
Filed: 1985-05-07
Abstract: PURPOSE:To easily manufacture a strong performed body with no chipping at low cost by a method wherein an elastic body is employed at the bottom part, in which convexities are formed, of the preformed body. CONSTITUTION:Firstly, raw material is charged after an upper punch 3 is drawn out. At this time, much raw material flows in concavities 2, because the concavities are designed larger in consideration of the compressibility of material and final dimensions of a preformed body. Secondly, after the raw material is packed uniformly, the upper punch 3 is set in order to apply pressure to the raw material. The raw material is compressed and a bottom elastic body 1 is also compressed so as to reduce its height as the pressure is increased. Consequently, the raw material flowed in the concavities 2 is compressed vertically. The vertical compression of the bottom elastic body 1 results in the contraction of the bottom elastic body in the diametral direction. As a result, the raw material in the concavities is compressed both in the direction of height and in the radial direction so as to be tightly shaped. Finally, when the applied pressure is removed, the shape of the bottom elastic body 1 is restored to its initial condition and clearance is developed between the shaped leg part and the concavity of the elastic body and consequently the leg part can be prevented from chipping at some part when the preformed body is taken out of a mold.
