IPC: H01L31/042
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To effect excellent mounting for flashing by a method wherein the rising piece of the end part of a roofing plate is covered with the fixing piece of a solar battery frame and a press fitment is arranged, and the fixing piece is fixed on the structural material side by a bolt inserted between the rising piece and the fixing piece. SOLUTION: The end part of a premolded roofing material 9 mounted in a state to be arranged in a longitudinal direction is caused to rise in a waterproofing pan-form state, and rainwater flowing over the surface of a roofing plate 9 is prevented from penetrating through the end part to the back of a hut. Further, since the rising piece 15 is covered with the fixing piece of a solar cell frame 10, flashing is further improved. Besides, a fixing piece is fixed on the roof structural material side by a bolt 11 and a press fitment, and fixing of the roofing plate 9 fixed through the fixing piece is brought into a complete state. Further, both fixing of the frame 10 and fixing of the roofing plate 9 are simultaneously executed by a single bolt 11. This constitution reduces the number of working processes, decreases the number of parts, and improves waterproofing performance.

Title: Attitude controllor for antenna on moving body
Inventor: SUZUKI KATSUO
IPC: G01S3/44
Filed: 1990-11-30
Abstract: PURPOSE:To keep receiving quality constant even if the receiving level of an antenna on a moving body is fluctuated and to make it possible to obtain the quicker tracking speed by providing a second control means for determining the turning amount of one step of the turning and driving of a first control means. CONSTITUTION:A first control means (MPU) 4 turns and drives a BS antenna Ant with an azimuth mechanism 141 and an elevation mechanism 151 stepwise in the forward and reverse directions. The attitude of the antenna Ant is changed to a position where the received signal level BSs of a BS receiver BSR is high. Thus, the attitude of the antenna Ant is adjusted at the excellent receiving level for a radiowave source. A second control means (MPU) 4' determins the amount of turning of one step of the turning and the driving of the MPU 4 so that the amount is large when the level is high and the amount is small when the level is low in correspondence with the received signal level BSs of the receiver BSR. Thus, the constant receiving quality is secured, and the quicker tracking can be performed. In the environment wherein only the low receiving signal level BSs is obtained, the deflecting angle of the antenna is made small, and the antenna Ant is changed into the direction where the received signal level BSs becomes high. Thus the high receiving quality is obtained.

Inventor: SANO YOSHIYUKI
IPC: H03K3/037
Filed: 1990-11-30
Abstract: PURPOSE:To attain reset without power supply off when malfunction takes place once and to attain a latch operation without calling for increase in number of components by providing 1st and 2nd input terminals, an R-S latch circuit, a logic circuit at the input and output and an output terminal to the latch circuit. CONSTITUTION:A change in a level at an input terminal IN71 is to be observed when a level of an input terminal IN72 falls down to a low level and the initializing is set. While the input terminal IN71 is at a high level, an output terminal OUT7 is at a high level and latch state is formed when the input terminal IN71 falls down from the high level to a low level and the output terminal OUT7 keeps a low level. The latch state is reset by changing the input terminal IN72 to a high level. Thus, the latch operation is attained without calling for number of components, and even when an erroneous signal is inputted to cause latch state, the latch circuit is easily reset by having only to change a 2nd signal level.

Title: Rotary encoder
Inventor: FUKUNISHI KIICHI
IPC: H03M1/24
Filed: 1990-11-29
Abstract: PURPOSE:To prevent, inputting errors and to efficiently input a plotted figure, etc., by providing a switch which turns OFF outputs of an X-encoder and a Y-encoder simultaneously. CONSTITUTION:A switch 6 simultaneously turns OFF the signal outputs of the moving amount generated from an X- and a Y-encoders 2a, 2b. When the switch 6 is depressed, a ground line connected to the switch 6 is disconnected, and the signal outputs of the moving amount from the X-, Y-encoders 2a, 2b are turned OFF. Therefore, when the switch 6 is depressed, the position of the cursor is not influenced by the movement of the rotary encoder, thereby preventing an erroneous input due to the vibration of a hand. Moreover, the same effect can be obtained even when the cursor is stopped by shutting a signal line of the moving amount to the X- and Y-axes.
