Title: Control unit of cassette decks
Inventor: ITOU FUMIO
IPC: G11B15/02
Filed: 1978-03-13
Abstract: PURPOSE: To make constitution simple by logic-processing the state detection pulses such as of stop, tape end, etc. and the set signal according to modes.  
     CONSTITUTION: The tape end detecting circuit 5 of an operating part 1  generates the first pulse of the width determined at the stop detection of a tape or the detection of the tape end. The third pulse of the same beginning end as that of this pulse and a narrower width is generated from a pulse switching circuit 7 and further the second pulse of narrower width than the first pulse is generated from a timer circuit 6 upon lapse of the specified time after turning on of power source. The first pulse appears at the final end of the second pulse and is applied together with the set signal corresponding to the mode having been coupling processed and selected so as to inhibit the appearance of the first pulse in the third pulse period to a logic processing circuit 2, whereby the solenoid driving circuit and motor driving circuit or other cooperating with the solenoid timing circuit of the drive part 3 are controlled.

Title: Printer
Inventor: TERAHARA TOSHIYASU
IPC: B41J25/312
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To facilitate the paper refilling work to a printer. SOLUTION: The lock of the lock mechanism L engaging a lower unit 14 having a platen 12 with an upper unit 16 having a thermal head 15 is released by revolving a printer cover 7 in an open direction and the upper unit 16 is opened in connection with the opening operation of the printer cover 7. By this constitution, paper refilling work becomes easy because the printer cover 7 and the upper unit 16 are opened at the same time by one work. When the printer cover 7 is revolved in a closing direction to be brought to a closed state, the upper unit 16 is set to a half-open position but the lock mechanism L is brought to a lock state by pushing down the pressure member 23 partially projected from the printer cover 7 to close the printing cover. By this constitution, the lower and upper units 14, 16 are certainly locked to protect the thermal head 15.

Title: Solar heat collecting apparatus
Inventor: UENISHI MASAHISA
IPC: F24S90/00
Filed: 1981-02-27
Abstract: PURPOSE:To prevent vaporization and deterioration of a heating medium, by connecting an enclosed expansion tank to a heating medium circulating circuit in which a  heat collector, a heat exchanger and a circulating pump are connected in series, and  effecting ON-OFF control of operation of the circulating pump by means of a differential temperature thermostat. CONSTITUTION:When the solar heat is available and the temperature of a heating medium in a heat collector 1 is higher than that of the heating medium in a heat exchanger 3, the value of resistance of a high-temperature sensor 16 becomes lower than  that of a low-temperature sensor 17, whereby an output is produced from a differential  temperture thermostat 15 for starting operation of a circulating pump 6. This causes  circulation of the heating medium in a circulating passage 10, and heat is exchanged  between the heating medium heated in the heat collector 1 and water in a heat accumulating tank 2 by means of the heat exchanger 3, so that the temperture of water in the  tank 2 is raised. On the other hand, when the solar heat becomes unavailable and the  temperature difference of the heating medium detected by the two sensors 16, 17 becomes zero, operation of the circulating pump 6 is stopped by the thermostat 15. In the  above arrangement, expansion of the heating medium in the circulating passage 10 is  absorbed by an enclosed type expansion tank 8 connected to the passage 10.

Title: Method for controlling plate thickness
Inventor: MORIMOTO SADAO
IPC: B21B37/18
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To roll a metal plate into a desired thickness without generating defects in shape of the metal plate regardless of whether the plate thickness is thick or thin. SOLUTION: At the begining of rolling, by executing absolute value control, the thickness in rolling is allowed to fall within a prescribed range to a certain degree (Step 10-103). But, at a proper time after that, the absolute value control is switched to static control (Step 103, 104). Because this static control is control for keeping a screw-down location constant, the variation of the screw-down location to the metal plate is suppressed to small amount (Step 104-106) and the generation of defects in shape is prevented.

Title: Apparatus for detecting position
Inventor: SHIBUYA MASATO
IPC: G01B9/02
Filed: 1985-02-16
Abstract: PURPOSE:To enable the accurate positional detection of an object even when various optical systems are interposed between a light source and the matter, by using such a characteristic that the intensity of interference light by an interference optical system changes corresponding to the relative movement amount of matter to be inspected. CONSTITUTION:The light from a coherent light source 1 is supplied to matter 2 having a diffraction lattice G at an incident angle thetaA and the diffracted light with an angle thetaB is reflected by a reflective mirror 3 to be guided to a semi-transmissions mirror 4. Diffracted light with an angle thetaC has reached the mirror 4 and the interference light of two diffracted lights is incident to a photoelectric detector 5 to output a photoelectric signal. When the matter 2 relatively moves to an X-direction, the phases of the diffracted light with the angle thetaB and the diffracted light with the angle thetaC change to generate phase difference and the intensity of light detected by the detector 5 changes. The output from the detector 5 and the signal from a drive means 10 are inputted to an operator 20 and the state of the change in the intensity of the photoelectric signal to a relative movement amount (x) is detected and the matter is moved so as to obtain a predetermined state to perform positional alignment. As mentioned above, the diffraction lattice may be illuminated by the light source and the restriction from an interposed optical system is reduced.

Title: Method for improving luminous efficiency of plasma display
Inventor: RIN KAISEI
IPC: H01J17/04
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To improve luminous efficacy of a plasma display. SOLUTION: The luminous efficacy is improved by coating phosphor particles 11, 21 with dielectric layers 10, 20. The dielectric layers 10, 20 have refractive index between the reflective index of the phosphor particles and the refractive index is vacuum to ultraviolet rays 14, 24 emitting out of plasma. In the case the thickness of the dielectric layers 10, 20 is controlled within a range from 0.5 to 5μm, the dielectric layers 10, 20 decrease the reflectivity of the phosphor particles. In the case of a coating 0.1-0.5μm thick, the reflectivity is decreased due to the interference of the light beams reflected in the vacuum/coating layer interface and the coating/phosphor interface. Several methods to form such reflection preventive films are provided.  A CVD method, a PVD method, and method carried out by suspending phosphor particles in a molten dielectric material and then slowly pouring the resultant suspension on the surface of an adhesive or non-adhesive surface are among the methods.
