Title: Manufacture of piezoelectric oscillator
Inventor: INUI JIYUNJI
IPC: H03H3/02
Filed: 1983-02-28
Abstract: PURPOSE:To eliminate a material and a time loss by forming cut grooves in a wafer, and detecting the oscillation constant of an oscillation energy confined type piezoelectric oscillator before the wafer is cut. CONSTITUTION:The thickness (t) of the wafer is 500mum and the width 10 is 1,000mum. The depth of grooves cut in the top and reverse surfaces of the wafer is 20-30% of (t). Namely, the stripe width is set to an integral multiple of the wafer thickness (t) as a reference, and the oscillation constant of the piezoelectric oscillator after its assembly is grasped almost completely while cut grooves 9 are cut in the wafer to depth which is 20-30% of the thickness (t). Etching is carried out to remove strain due to the wafer groove cutting before electrodes are vapor-deposited. Then, an electrode pattern 2 is vapor-deposited over the entire surface of the wafer. The oscillation constant of the piezoelectric oscillator is measured in said wafer formation state to measure the oscillation constant equivalent to that of the oscillator which is to be mounted on a substrate even in the beginning of the manufacture.

Abstract: PURPOSE:To enable compositions of a plurality of kinds of refrigerants in a main circuit to be varied without requiring any heater at all by a method wherein a refrigerant separation device having a function film facilitating a passage of a specified type of refrigerant is connected, and a refrigerant storing unit is connected to a passing-through side of the function film as well as its non-passing-through side. CONSTITUTION:In case that non-azeotropic refrigerants R-22 and R-13B1 are applied and a non-passing-through refrigerant is stored, a sub-metering device 28 is properly opened in compliance with a degree of opening of a main metering device 23. When a sub-metering device 26 is fully closed, liquid refrigerant flows into a separator 101 and R-22 which easily passes through a function film 103 is returned back to an inlet port of an evaporator 24 through a storing unit 27 and a sub-metering device 28. In turn, R-13B which is difficult to pass through the function film 103 exits an outlet pipe 106, is stored in the storing unit 25, resulting in that a rate of R-13B1 in the main circuit is decreased and a rate of R-22 is increased. In case that the passing- through refrigerant is to be stored, the sub-metering device 26 is properly opened in compliance with a degree of opening of the main metering device 23. When the sub-metering device 28 is fully closed, a rate of R-22 in the main circuit is decreased and a rate of R-22 is decreased.

Title: Data processing system and channel adaptor
Inventor: SERAFUIN YOZEEERIIZA GARUSHIA
IPC: G06F13/20
Filed: 1994-03-02
Abstract: PURPOSE: To dispatch a channel descriptor block(CDB). CONSTITUTION: A processor stores plural CDB in discontinuous storage positions without designated linkage, sequentially transfers CDB to an adapter and causes the adapter to manage the schedule and the processing of data transfer, which CDB define. During a request signal process for transferring CDB, the processor polls the use state of a requested register in the adapter. When it can be used, the addresses of respective CDB are written into the requested register. The adapter schedules the processing of CDB having the address. A 'channel descriptor table (CDT)' which the adapter manages defines the processing order of respective CDB which the respective requests designate. The adapter introduces plural CDB to a link list queue which CDT defines in the order of reception on the plural requests.  The adapter retrieves plural CDB which are sequentially queued by using CDT information and controls the execution of a data transfer operation which CDB defines.

Title: Optical exchange device

IPC: H04Q11/00
Filed: 1983-03-01
Abstract: PURPOSE:To attain ease of a large scale of constitution of an exchange by connecting in cascade a means executing time division at each wavelength and a means executing division of wavelength at each time slot in the preset order. CONSTITUTION:When an input optical signal and an output optical signal subject to time division multiplex and wavelength division multiplex are exchanged, one or plural means T11, T13 performing time division exchange at each wavelength and one or plural means lambda12 performing wavelength division at each time slot are connected in cascade in the preset order by an optical highway subject to time division multiplex and wavelength division multiplex. Thus, since the means T and lambda are connected by an optical signal subject to time division multiplex and wavelength division multiplex, only one optical fiber cable is enough for the connection. Further, no large scale spatial switch is required in the inside of the means T and lambda, then a large scale exchange is constituted easily.

Abstract: PURPOSE: To prevent a tungsten filament from being deteriorated and disconnected by turning off a halogen lamp after the rising value of the color temperature of tungsten is detected when the halogen lamp is made to flicker based on the color temperature of the tungsten. CONSTITUTION: The rising value of the color temperature of the tungsten generating a halogen cycle is detected after the halogen lamp 5 is turned on. Thereafter, the lamp 5 is turned off. Thus, the surface temperature of a fixing roller 6 becomes the temperature within a specified range and the disconnection of the tungsten filament is reduced. Therefore, this device is provided with a detection part 1 detecting the color temperature of the tungsten of the lamp 5. By guiding the detected color temperature to a flickering part 2 for making the lamp 5 flicker through a connection line (a) and making it arrive at the previously decided color temperature, the lamp 5 is made to flicker. By the flickering part 2, the shortest flickering time can be set by using a shortest flickering part 3. After the lamp 5 is turned on, it is not turned off until the shortest flickering time elapses.

Abstract: PURPOSE: To facilitate the discrimination of the positional relationship of reflected signals from reflection points by using a sine wave as a measuring signal and replacing the delay time in which a photosignal is transmitted within a photofiber for the sweep frequency width of a sweep oscillator corresponding to the delay time.  
     CONSTITUTION: A laser 2 is driven by the output sweep ocillator 10 sweeping the frequency of f 0 Wf 1 Hz at the sweep speed of f s Hz/sec., and a photosignal generated is sent out to a photofiber 4 via a photo-branching circuit 3. The photosignal is reflected at a break point 5, and is supplied to a light receiving element 6 again through the photofiber 4, and the photo-branching circuit 3, thus being converted into an electric signal and introduced into a modulator 11. The output of the sweep oscillator 10 is also supplied to the modulator 11, and in the output there appears a sine wave signal having a frequency equal to the difference between the frequency of the above described feflection signal and that of the sweep oscillator 10. This sine wave signal is passed through a filter 12 and is supplied to a spectrum analyzer 14. When the time required by the photosignal for reaching the light receiving element 6 from the sweep oscillator 10 is represented by ΔT, f s .ΔT is read out on the surface of the CRT of the analyzer 14, whereby ΔT, that is, the position of the break point 5, is obtained.
