Title: Ball-and-roller bearing cage
Inventor: GERUHARUTO KURAUSU
IPC: F16C33/46
Filed: 1990-04-09
Abstract: PURPOSE: To guarantee the positions of cage ends and to permit circumferential movements by forming a projection at a cage end limiting a slit provided in a bearing cage, and engaging the projection in a slit in the other cage end so as to enable circumferential relative movements. CONSTITUTION: A ridge plate 8 is formed adjacent to an end face 7 at the cage end 6 of a rolling bearing and a corresponding recess 9 is formed in the other cage end 10. The ridge plate 8 and the recess 9 are provided respectively with a projection 11 and a circumferentially extending slit 12 (cut) and engaged with each other. Since the slit 12 is circumferentially longer than the projection 11, the cage ends 6, 10 move circumferentially without hindrance. A bearing needle is stored in a cage pocket 14 and prevented from dropping by a holding projection 15. Thus, the positions of the cage ends are guaranteed and they are put into circumferential relative movements to each other.

Abstract: PURPOSE: To make the loading and unloading of the subject of scanning easier and to make a scanning device smaller by employing a semicylindrical cylinder in a scanning and recording system of the inside surface of cylinder.  
     CONSTITUTION: A laser beam B modulated in response to a picture image signal is reflected at a prism 13, through a lens 14, a fixed mirror 4 and a rotary mirror 3 and focused on a photosensitive material 2 fixed on a semicylindrical cylinder 1. By rotating a rotating mirror 8 having a rotary axis in a line of the center of curvature of the cylinder 1 in the direction of the arrow, primary scanning is done. Through a motor 9 and a belt 6 further by driving a screw axis 8 with the motor 9 and by moving a light beam guide 12 along a guide 15, subscanning in the horizontal direction is performed. Through the process, the loading and unloading of the photosensitive material 2 become easier and a compact scanning device is obtained.

Abstract: PURPOSE:To obtain a rapidly processable multilayered silver halide color photographic sensitive material whose ground has superior whiteness by forming a green-sensitive silver halide emulsion layer contg. a specified amount of a specified photosensitive dye and silver halide particles made of silver chloride. CONSTITUTION:A green-sensitive silver halide emulsion layer contg. photosensitive dye represented by the formula by 1.51X10<-4>-0.57X10<-4>mol per 1 silver halide and silver halide particles made practically of silver chloride is formed. In the formula, Y1 is O or N-R4, Y2 is O or N-R5, each of Z1 and Z2 is a group of atoms required to form a benzene or naphthalene ring, each of R1-R5 is alkyl, R3 is H, alkyl or the like, X is an anion and n=1 or 2. The preferred amount of the photosensitive dye used is 1.13X10<-4>-0.76X10<-4>mol per 1mol silver halide. An excessively large amount of the dye deteriorates the whiteness of the ground and an excessively small amount of the dye reduces the green sensitivity.

Abstract: PROBLEM TO BE SOLVED: To make possible reducing charge/discharge power of a first storage means and reducing a transistor size in the first storage means by charging/ discharging respective NOT gate source terminals constituting a second storage means with a first storage means and transferring the data. SOLUTION: Since p type 151, 154 and n type 152, 155 of a MOS transistor constituting a second memory cell 150 aren't operated as an active element, the necessity that the charge/discharge is performed against the drive of these MOS transistors 151, 152, 154, 155 when the data are transferred to the second memory cell 150 is eliminated. Then, the necessity that the drive power of the first memory cell 110 and NOR gates 120, 130 are enlarged is eliminated, and thus, respective transistor sizes are reduced. Further, since respective MOS transistors constituting the second memory cell 150 aren't connected directly to ground, and aren't operated as the active element, a malfunction in the second memory cell 150 due to potential fluctuation of a source line VDD is prevented.

Title: Inter-processor communication system
Inventor: IGARASHI MASAMI
IPC: H04L29/08
Filed: 1986-04-23
Abstract: PURPOSE:To discriminate a receiving buffer busy state from a processor fault by setting up the time interval of the retransmission processing of the same data at the failure of data transmission to a processor to be transmitted to a prescribed time determined by a timer to control the retransmission. CONSTITUTION:When the failure of transmission of transmission data A to a processor 2 is detected by a control part 13 after the transmission of the data A to the processor 2, a processor 1 reregisters the data A in the leading address of a transmission waiting data queue 12. Logic '1' is written and stored in a flag corresponding to the data A in a control table 14 during the stop of transmission. Then, the counting contents of a counter 15 corresponding to the processor 2 are updated. The timer 16 is reset and starts to count up time, and when a previously fixed time is counted up, a control part 13 generates a retransmission command of the data A. A transmission part 11 extracts and retransmits the same data A registered in the leading address on the basis of the queue 12. Thus, the receiving buffer state can be discriminated from the processor fault.
