Title: Multi-step compressor
Inventor: OOTANI IWAO
IPC: F04B49/02
Filed: 1981-03-30
Abstract: PURPOSE:To prevent the occurrence of drain by regulating the compressed air flowing through a conducting tube to the proximity of the atmospheric pressure when the temperature in a tube conducting between the low pressure side compressing section and the high pressure side compressing section is low. CONSTITUTION:A temperature detector 15 will detect the temperature in a conducting tube 9, and when said temperature is below predetermined level a switch section 15A will close and the inlet 18 of a sluice valve 16 is held in the choked state. In the suction process of the low pressure side compressing section 5, the air supplied through an atmospheric air take-in tube 7 will pass only through a throttle path 19 thus to limit the flow. Since the compressed air having the pressure near to the atmospheric pressure will pass through the conducting tube 9, the drain will not occur in the compressed air. Said compressed air is led as it is to the high pressure side compressing section 6, then further compressed to flow through a delivery tube 10 into a tank 1.

Title: Ic base plate with heat pipe structure
Inventor: ANDOU MIGIWA
IPC: F28D15/04
Filed: 1983-03-18
Abstract: PURPOSE:To improve heat radiation capability by disposing a spacer to form an internal space between an IC base plate and an opposing plate, and placing an IC element in the hollow space so that the rate of circulation of an operating fluid may be enhanced without enlarging the base plate. CONSTITUTION:As a higher capillary suction effect is achieved by an intermediate frame 1 of a spacer B tightly attached to the surfaces where wicks 7, 7a of a base plate A and an opposing plate C are formed, an operating fluid W condensed n a heat radiation section is sucked to a wick made up in cooperation with the intermediate frame 1, and is rapidly returned W2 to a heat emitting element section. The vapor (b) evaporated by the heat emitting element section passes through an orifice 3 to enter into a vapor passage space 9 via a cavity 2 to move on to the heat radiation section. Because of this, as the flow is not hindered by a vapor flow moving in an opposite direction, which was the case in the prior art, the capillary suction effect of the operating fluid is enhanced, and so, even if the heat generating secton is located above the heat radiation section, the function is ensured. In addition, there is no need to change the outer diameter of a heat pipe used to date, allowing a compact structure.

Title: Time counting system
Inventor: TOKISAKI SATORU
IPC: G04G99/00
Filed: 1982-03-24
Abstract: PURPOSE:To always hold the delay in time within the cycle of a correction signal by periodically correcting skipped reading of count signals due to a temporary increase in the load of a processor. CONSTITUTION:The output of an oscillator 21 is divided 32 to a pulse 31, latched 23 and applied to a processor 30 as count signal 26. The pulse 31 is divided 24, latched 25 and applied to a device 30 as correction signal 27. The device 30 reads out the signal 27 by detecting the signal 26 and outputs a signal 28 to reset the latches 23 and 25. At this point, when the signal 27 is set, the counting is repeated until a difference from internal time counts is reached. When the signal 27 is reset, one time counting is performed. When setting time for correction or the like, the dividers 22 and 24 are reset by a signal 29 and the latches 23 and 25 are reset by a signal. Therefore, the generation of the count signal 26 is made possible synchronizing with the time correction.

Title: Device for detecting linear velocity of recording track of recording disk
Inventor: YOKOGAWA FUMIHIKO
IPC: H02P29/00
Filed: 1983-03-19
Abstract: PURPOSE:To integrate easily the titled device without using capacitor and, at the same time, improve the reliability of the device, by generating edge pulses synchronously to a frequency which is integer times as large as a clock signal for demodulation by detecting the leading edge and trailing edge of the signal and detecting the linear velocity of a recording track in accordance with the outputted content of each stage of a shift register. CONSTITUTION:A read EFM signal B is inputted into a PLL circuit 1 and a self-clock for demodulation contained in the signal B is extracted and sent to a demodulating section. The signal B becomes the data input of a DFF 2 and each Q-output C and D of the DFFs 2 and 3 becomes two inputs of an exclusive OR gate 4. A reference clock signal A having a frequency 2f which is twice as large as a master clock for demodulation is generated from a clock signal generator 5 and the DFFs 2 and 3 are operated and, at the same time, the shifting operation of a shift register 6 composed of 47 stages is controlled. The frame sink pattern length is detected by the shift register 6. Since the content of the shift register 6 varies in accordance with the linear velocity, the linear velocity can be detected by discriminating the content of the shift register 6.

Title: Image recording copier
Inventor: SAKAI YUKIO
IPC: G03G15/09
Filed: 1980-04-09
Abstract: PURPOSE:To decrease light emission time and suppress power consumption and heat evolution by providing a means of performing copying of originals through positive transfer development by an electrophotographic system, and a means of performing recording of images through reversal development by laser beam or the light of a light emitting device. CONSTITUTION:At the copying of an original, positive development is accomplished by the toner of negative polarity, with the developing bias as zero potential. At the image recording by laser beam, the voltage E which is roughly equal to the charging potential of a photoreceptor or is higher than the charging potential is applied to the sleeve 15 of a developing device 14. Since at this time, an opposite electric field is produced in the part of the zero potential of the photoreceptor, the toner of positive polarity sticks on the laser exposed part on the photoreceptor and reversal development is accomplished. The time during which the semiconductor laser is allowed to emit beam is shortened by this and therefore the power consumption and heat evolution are suppressed and the life of the semiconductor layser is prolonged.

Title: Picture encoding/synthesizing system
Inventor: AONO TOMOKO
IPC: G06T3/00
Filed: 1989-02-28
Abstract: PURPOSE:To prevent an objective picture from being hidden by a background picture when the pictures are synthesized by segmenting the objective picture from the component picture, and discriminating the objective picture from the background picture in the component picture. CONSTITUTION:In three component pictures P1, P2 and P3 surrounded by dot lines, respective hatched portions are objective pictures O1, O2 and O3, and the other parts are background pictures b1, b2 and b3. In the component pictures P1 to P3, m-bit codes are allocated to respective picture elements as area information to discriminate the backgrounds b1 to b3 from the objects O1 to O3, and by compressing only the part indicated to be the object by the area information, an information quantity and a calculating time can be reduced. Further the area information can discriminate the objective pictures O1 to O3 in the component pictures P1 to P3 from the background picture parts b1 to b3. Thus even when the background pictures of the other component picture are overlapped on the objective pictures O1 to O3 of the component pictures P1 to P3, the data of the objective pictures O1 to O3 can be prevented from being erased.

Filed: 1983-03-24
Abstract: PURPOSE:To facilitate the handling of a camera by allowing the rear cover of a device to be closed manually when the rear cover is not closed owing to a shortage of the capacity of built-in batteries. CONSTITUTION:When the rear cover 3 is being closed, a part 3a of the rear cover 3a presses a switch 8 against a spring 14 and a contact piece 8a contacts a pattern part 15 to turn on a switch 8, so that a battery check circuit 17 checks the capacity of the batteries. When the capacity is deficient, the circuit 17 is powered off, so a magnet 12 is also powered off and a lock member 9 which is released from the magnet 12 enters a hollow 18 by the resiency of a spring 13 and stops therein. The projection 3b of the rear cover 3 abuts on the lock member 9 to inhibit the closure of the rear cover 3. In this case, a rear cover opening/closing member 20 is slid to right to expel the lock member 9 from the hollow 18, closing the rear cover 3 completely. Therefore, the handling is facilitated when the batteries are taken out of the camera for storage and in other cases.
