Title: Production of electrophotographic sensitive body
Inventor: KASAHARA MASAHIKO
IPC: G03G5/14
Filed: 1989-04-17
Abstract: PURPOSE:To improve the photosensitive body in such a manner that the degradation in electrostatic charge is lessened to an adequate level by heating a base body at the temp. within a specific range and forming an electron implantation suppressing layer consisting of an Al2O3 film on this base body, then forming respective layers on the electron implantation suppressing layer. CONSTITUTION:The base body 101 is heated to 250 - 300 deg.C and the electron implantation suppressing layer 102 consisting of the Al2O3 film is formed on this base body 101. A charge transfer layer 103, a charge generating layer 104 and a surface protective layer 105 are successively formed on this electron implantation suppressing layer 102. The electron implantation suppressing layer 102 formed by this heating treatment suppresses the implantation of electrons to the charge transfer layer 103 from the base body 101, i.e. plays the role of a barrier layer. The quantity of the electrostatic charge of the photosensitive body is lowered to the level which is of no problem in practicable use even in the high-temp. and high-humidity environment in this way.

Title: Pressure controller for rubber weir
Inventor: MURAMATSU TAKEO
IPC: E02B7/20
Filed: 1979-07-31
Abstract: PURPOSE: To enable a rubber weir pressure controller having a simple design to reliably operate by allowing one end of a conduit constituting a pressure controller for a rubber weir used as a seawall or the like at a high tide to communicate with a lower part of the rubber weir, while making the other end open at its upper part.  
     CONSTITUTION: A rubber weir 1 is filled with a gas such as air by a pump P or the like to rise across a riverbed 3 to form a weir. One end of a conduit 4 constituting a pressure controller 2 is communicated with the lower part of the rubber weir 1. The conduit 4 first extends downward, then is bent upward so as to be substantially U-shaped. A container 5 having a diameter larger than the conduit 4 is connected to the upper end of the bent portion of the conduit 4. The pressure controller thus constituted operates economically because it uses the river water as a filler, and the water level in the container 5 permits the internal pressure in the rubber weir to be accurately sensed.

Title: Charging circuit for storage battery
Inventor: SHIOJIMA NOBUO
IPC: H02J7/10
Filed: 1988-04-21
Abstract: PURPOSE:To suitably control charging irrespective of the type of a storage battery, a charging current, an environmental temperature and the like by detecting a fine voltage variation presented at the terminal voltage waveform of the battery at the end of charging. CONSTITUTION:When a start pulse generated at the time of turning ON a power source of a charging circuit is applied to the set terminal S of an FF 8, an output terminal Q becomes a high level, thereby quickly charging it. When it arrives at the end of charging, oxygen gas is generated from the anode of a storage battery 1, and a fine voltage variation is intermittently presented in the waveform of the terminal voltage VB of the battery 1. An output corresponding to the fine voltage variation of the voltage VB of the battery 1 is presented at the output terminal (b) of a bypass filter 4. When the output of the filter 4 exceeds a reference voltage Vth by a voltage comparator 7, the output of the comparator 7 becomes a low level, thereby setting the FF 8. Since the terminal Q of the FF 8 becomes a low level, a charge controller 2 becomes a charge control state to stop charging of the battery 1 or reducing a charging current.

CONSTITUTION:A shaped grinding wheel on a grinding wheel shaft is rotated, while a shaping device 20 turns its point-shaped truing tool 25 mounted to a tool shaft hole 5a, and both the grinding wheel and the truing tool 25, while being brought into contact, are relatively moved, further by NC controlling a proportion of a rotary speed of the grinding wheel to a rotary speed of the truing tool 25, many craters are continuously formed along a spiral track in the grinding wheel in its shaped surface. By an envelope of a group of these craters, the shaped surface is corrected to a desired shape. Next the shaped surface of the tool grinding wheel, after this shape correction, performs dressing by a dressing brush 29. Thus the tool grinding wheel enables its shaping process to be easily performed on an NC tool grinding machine.

Title: Frame synchronizing system
Inventor: AIDA HISAFUMI
IPC: H04L7/08
Filed: 1989-04-17
Abstract: PURPOSE:To reduce the probability of causing pseudo the acquisition of synchronism by making same codes consecutive for hook information bits added to an identification header when a counter-ground hooking state is changed and making codes alternative in other cases. CONSTITUTION:A hook information bit deciding circuit 7 decides a hook information bit 107 assigned to an identification header 101 inputted from an identification header detection circuit 2 and a hook information bit state transition monitoring circuit 8 monitors whether or not the hook information bit 107 applies state transition based on the decision. Only when a counter-hooking state of the information bit 107 is changed, the same code is consecutively transmitted to represent the change state and codes are transmitted alternately in other cases. Thus, the probability of causing the pseudo acquisition of synchronism is reduced when frame synchronization is taken by the identification header 101.

IPC: A61C17/00
Filed: 1993-04-23
Abstract: PURPOSE:To automatically supply water without malfunction by placing a light cup made of paper on a cup receiver. CONSTITUTION:When a cup 1 forming a conductive film at the bottom is placed on a cup receiver 2, a proximity sensor 8 senses the conductive film and turns on an opened contact SW 1. Thereby a solenoid valve control circuit 10 is operated and a solenoid valve 6 is opened in the lapse of the time setting a delay timer 10a and the water supply by a water supply tube 7 is started. The weight is increased as the water is filling the cup 1, and the cup receiver descends against the energizing power of the spring not shown in the figure. When it reaches the prescribed amount, a switch 9 for detecting constant amount of water is operated to turn off a closed contact SW2. Thus, the solenoid valve control circuit 10 closes the solenoid valve 6 to stop the water supply from the water supply tube 7.
