Title: Variable diffuser
Inventor: HIGASHIMORI HIROTAKA
IPC: F04D29/46
Filed: 1982-03-19
Abstract: PURPOSE:To suppress exfoliation of a flow, by rotating a leading blade and qualizing a flow angle to an angle formed by a circumference and camber line to prevent an increase of an attack angle. CONSTITUTION:Fluid 8 flows in along a camber line 5 of a guide vane 20, because an angle betab and angle beta are almost equal, fluid 9 in the side of a pressure surface 6 and fluid 10 in the side of a negative pressure surface 7 flow respectively along the surfaces 6, 7. When a flow amount of the fluid decreases, the flow angle beta is decreased smaller than at a design flow, and a piston 17 is pulled to rotate a seat 14 clockwise and move a leading blade 12 so as to equalize the angle beta almost to the angle betab. Accordingly, an attack angle  (betab-beta) is never increased to prevent exfoliation of a flow.

Title: Closed type compressor
Inventor: NAKAMURA MITSURU
IPC: F04C28/08
Filed: 1989-02-27
Abstract: PURPOSE:To perform high speed and high-precise control of the rotation speed of a compressor by a method wherein a completely closed type rotation position detecting sensor to detect the rotation positions of a rotary shaft and a rotor is incorporated in a space surrounded with a stator, a coil end, and a rotor, being an electrically- operated element, and a closed container. CONSTITUTION:A gear 16 is rotated along with rotation of a rotor 3, and when a crest of tooth is rotated to a position facing the tip of a fixed arm art 20, a magnetic passage running from the N-pole of a magnet 23 to the S-pole of the magnet 23 through an upper seat 21, a post part 22, a gear 16, the fixed arm part 20, and a lower seat 19 is formed as shown by a dotted line. When the tooth shape of a gear 16 is formed such that the change of the tooth shape from the crest of a gear to the root thereof is steep, the magnetic passage is rapidly generated right before a rotation position where the crest of the gear approaches the tip of the arm part 20 with a shortmost distance therebetween. Thus, when a magnetic flux is generated by passage through the post part 22, an induction voltage proportioning the differential value of the magnetic flux is generated to a winding 29 of a pickup 24 by an electromagnetic induction rule. The voltage is taken out through a hermetic terminal 27.

Title: Apparatus for and method of identifying coin
Inventor: JIYOOJI RIJINARUDO HAWAADO
IPC: G07D5/00
Filed: 1982-03-19
Abstract: Coin validation apparatus may be associated with a coin freed mechanism on coin receiving machines or form part of a coin sorting apparatus to check that coins are valid coins and not counterfeit. Recently, it has become particularly convenient to use the interaction between a coin and an alternating magnetic field to gauge various parameters of the coin thereby to determine if the coin is valid. In such a method the frequency of a feedback oscillator having a tuned electrical coil in its feedback loop is monitored when a coin is present adjacent the coil, the frequency is then monitored when a phase shift or time delay network is also included in its feedback loop, two parameter signals characteristic of the effect of the coin on both the inductance and the loss factor of the coil, are derived from these maintained frequencies and the two parameter signals are compared with reference values to determine if the coin is valid.

Title: Switching burning device
Inventor: NAKAMACHI ICHIRO
IPC: F23L1/00
Filed: 1988-02-26
Abstract: PURPOSE:To eliminate exhaust fan for high temperature while improving durability by connecting an air supply pipe and a venturi part by a piece of venturi piping, forming so that the diameter of a branch pipe is suddenly widened larger than that of an air introducing pipe and setting a switching mechanism. CONSTITUTION:Combustion air is introduced from an air introducing pipe 8 to reach a branch pipe 3. Since the diameter of the branch pipe is formed to suddenly widen larger than that of the air introducing pipe 8, a vortex is produced at the pipe wall part thereof and it is in a negative pressure state. When a change valve 12 is closed and another change valve 12' is opened, the vortex produced at the side of the change valve 12' is eliminated and negative pressure is not produced at the side of the change valve 12'. Therefore, air flow is sucked to the side of the change valve 12 by Coanda effect, flowed only at the side of an air supply pipe 4 and reaches a burner part 10 through an accumulator 11. Since part of the combustion air blows through a piece of venturi piping 7' at a venturi part 5', exhaust gas is effectively sucked and discharged from an exhaust part 16 by the combustion air.

CONSTITUTION:The nose section 5a of a temperature sensor 5 inserted into a shoulder section 8a for a tire 8 has four temperature-sensing sections 5d1-5d4, and the degrees of vulcanization Mt1-Mt4 are arithmetically operated by a control unit 3 from a temperature measured by the temperature-sensing sections 5d1-5d4 for the temperature sensor 5. The distribution of the degrees of vulcanization is arithmetically operated, approximating to a functional formula of the third degree from the position of the nose section 5a of the temperature sensor 5 in the shoulder section 8a in the tire 8 and the degrees of vulcanization Mt1-Mt4, and a minimum vulcanization value Mvt and a position Pt thereof are arithmetically operated. Even when the position of the minimum vulcanization value Mvt is moved in a member, the minimum vulcanization value Mvt is acquired with extremely high precision. When these minimum vulcanization values Mvt(Mvo) having high accuracy exceed Mvs, vulcanization is completed.

Title: Printing pattern converter
Inventor: MIYAOKA YASUSHI
IPC: B41J29/26
Filed: 1983-03-15
Abstract: PURPOSE:To make it possible to output an accurate straight line without modifying software, by converting an input data in a type mode print pattern into a bit pattern, converting the bit pattern into an output data in a dot mode printing pattern, and outputting the data to a printer. CONSTITUTION:When it is necessary to convert a type mode print pattern input into a dot mode printing pattern, a switch 1 outputs the input data as it is. When such conversion is needed, the switch 1 stores the print pattern input in an input buffer 2. A bit pattern generating circuit 3 stores in a register 31 a bit pattern 1010 generated in correspondence with one character (a) in a type mode print pattern. A dot mode print pattern generating circuit 4 selects a pattern '10' from a conversion table 41 and generates a dot mode print pattern (b). Thus, it is possible to draw accurate straight lines by utilizing, without any modification, a ready-made software which is developed for a printer, as an output device, which outputs data in a type mode printing pattern.

Title: Heat pump type hot water supply equipment
Inventor: TAKEI KATSUMASA
IPC: F24H4/00
Filed: 1989-02-23
Abstract: PURPOSE:To maintain hot water supply temperature within the range of normally preset value and prevent an increase and decrease in a hot water supply capacity at a hot water supply temperature by controlling a compressor with a control circuit which converts an output frequency of a inverter in proportion with the deviation between hot water supply temperature and preset temperature. CONSTITUTION:When compressor 1 starts its operation by a control circuit 5, and increases its rotary speed in conformity with a rise in an output frequency of an inverter 9, the compression ratio of refrigerant will be increased so that the refrigerant may be gasified at not temperature, responding with the compression ratio of the refrigerant. The gasified refrigerant passes through a primary side pipeline 2a of a user side heat exchanger and discharges condensation heat to supply water which flows in a secondary pipeline, and liquefied. The liquefied refrigerant passes through an expansion valve 3, gets expanded, takes away vaporization heat from open air in a heat source side heat exchanger 4, turns to the gaseous state again, and returns to the suction side of the compressor 1. When the output hot water temperature is high and an attempt is made to drop the output frequency of the inverter 9, the rotary speed of the compressor 1 will drop and the compression ratio of the gasified refrigerant will drop as well so that the gasified refrigerant at a relatively low temperature may be supplied to the primary side pipeline 2a of the user side heat exchanger 2. This serves to lower the temperature of supply water thus heat exchanged.
