Title: Holding method for standard telephone set of key telephone system
Inventor: SUGIURA RYUZO
IPC: H04M3/428
Filed: 1984-12-20
Abstract: PURPOSE:To make it possible to control holding of a line wire from a standard telephone set by judging the time of loop release in service with the line wire, namely, when it is within the first fixed time the standard telephone set is connected to the line wire again and when it is over the second fixed time the line wire is released from a holding circuit. CONSTITUTION:When a standard telephone set (TWST)a makes a hooking within the first fixed time Ts1, a CNT16 sets to work relays Id and He thru a DRV18 holding a HLD11 with the line wire 1 and also separating a TWST4 from the line wire 1. The CNT16 makes the relay Id to recover when a detected output b changes according to the on-hook of TWSTa, and moreover, it makes the relay He to recover after 10msec of delay time, for example. By this reason, the HLD11 is separated from the line wire 1 after the TWST4 is connected again with it and so a communication with the line wire 1 is held by the TWST4.

Abstract: PROBLEM TO BE SOLVED: To detect a frame (JITed frame) of a code in which a memory usable by a JIT(Just In Time) compiler of Java(R) is limited and which is compiled on a thread stack, in an environment where other frame coexist. SOLUTION: When a JIT compiler becomes short of memory in a certain thread, all threads are once stopped and next, an active method is found in each thread, i.e., a JITed code address in a thread stack is found. Frames are scanned one after another from the current stack point SP in each thread to the bottom of the stack when a JITed last frame record does not exist and to the address of a JITed frame that is indicated by the latest JITed last frame record of a list when the list exists. Next, a frame that is indicated by the JITed last frame record and a JITed frame which is traced from the frame are detected.

Abstract: PURPOSE:To perform stable and uniform coating over a long time, by once forming a revolving stream formed through a revolving groove into a uniform revolving stream through a revolving gap communicated with an emitting port on the total periphery thereof before injecting the same into a powder emitting port. CONSTITUTION:A powder paint is fed by air as shown by an arrow 13 to be emitted from a leading end emitting port 6 while clean air 7 is uniformized in its pressure through a ring shaped chamber 5 and subsequently converted to a revolving stream by the action of the revolving groove provided to a flow conditioning chamber 4 and formed into a uniform revolving stream by a revolving gap 3 to be injected in the powder paint fed by air from the total periphery of the emitting port 6.

CONSTITUTION:The nonmagnetic one component developer is filled into a hopper 1, stirred by an agitator 2, and triboelectrified between a developer supplying member 3 and the developer carrier 6 to be electrostatically stuck to the carrier 6. Then, the developer is carried to the developing region opposite to a photosensitive body 8, to visualize an electrostatic latent image. On the other hand, the carrier 6 is located on the upper part of the hopper 1, has the dispersion of the dielectric grain 6b in the conductive member 6a, and is made into a belt. When the part 6b is electrified by being rubbed on the member 3, a large number of micro closing electric fields MF are formed on the surface of the carrier 6. Therefore, when the developer electrified to the polarity reverse to that of the dielectric part 6b of the carrier 6 is used, the developer is strongly and electrostatically attracted to the surface of the carrier 6, and a large number of the developers are held.

Abstract: PROBLEM TO BE SOLVED: To enable convenience of improved photographing by providing a device, with which the battery of a reduced capacity can be switched to the other battery, without stopping the power supply to a camera, inside the battery. SOLUTION: A means for mounting another battery 2 is provided at a battery 4.

Title: Fm demodulation system
Inventor: KIZU SHIGEO
IPC: H03D3/00
Filed: 1984-12-21
Abstract: PURPOSE:To obtain a stable video signal output by taking a dropout caused in an FM signal as a higher level than the pedestal level of the video signal not as a large amplitude noise when the dropout period is demodulated. so as to attain easy and stable synchronizing signal separation. CONSTITUTION:A voltage comparator 2 outputs an FM signal pulse train only when an FM signal level at an input terminal 1 is higher than the preset level and outputs no pulse during dropout period. A pulse generator 3 generates a pulse at a prescribed width at both leading edge and trailing edge of the pulse train outputted from the voltage comparator 2 as shown in figure (c). Then a pulse period detection circuit 4 detects the period of the pulse generated by the pulse generator 3 and when the period is longer than the predetermined period, the circuit 4 generates a pulse by itself. That is, the circuit 4 generates a pulse only during dropout period as shown in figure (d). When an integration circuit 6 demodulated an FM signal, the pulse width generated in the circuit is selected so that the level of the dropout period is higher than the pedestal level of the demodulated video signal.

Consequently an optimum format corresponding to the scene for use can be obtained and the operability of the device can be improved.

Title: Image recorder
Inventor: SAKAI TOSHIO
IPC: G03B27/20
Filed: 1989-10-16
Abstract: PURPOSE:To easily separate an image recording sheet from a mask original plate and to reduce the cost of a recorder by providing an suction means for sucking a photosensitive recording medium to an exposure table which is in contact with the photosensitive recording medium at the time of exposure. CONSTITUTION:Until the exposure is finished, the exposure table 52 actuates an exhaust pump 59 to exhaust air between the exposure table 52 and the photosensitive recording medium 50 from a suction port 52a to make the medium 50 sucked to the exposure table 52. While an exposing device moves back, the exposure table 52 descends and the medium 50 is separated from a positioning device and the mask original plate 15R. The exposure table 52 moves back and forth until the three mask original plates 15R, 15G and 15B are positioned and exposure is finished, and the medium 50 is not separated from the exposure table 52. When a latent image is recorded on the medium 50, the exposure table 52 descends and a pump 59 is stopped, then the medium 50 is separated from the exposure table 52. Thus, the medium 50 is easily and surely separated from the mask original plate.
