Title: Variable wavelength laser device
Inventor: KAWAHARA HIDETO
IPC: G01J9/00
Filed: 1989-08-21
Abstract: PURPOSE:To detect the center wavelength of laser light for a long period by detecting the deviation between the center wavelength of band-narrowed laser light and the wavelength of absorbed rays in an absorber in the form of variation in laser light intensity detected by a light intensity detector. CONSTITUTION:Part of the laser light which is narrowed in band and set to specific wavelength by a wavelength selecting element 12 and a wavelength selecting element controller 17 is guided to an absorption cell 14. Vapor of molecules having sharp absorbed rays at wavelength nearly equal to the set wavelength is charged in the cell 14. Then the laser light which is passed through the cell 14 is guided to the laser light intensity detector 15 and the laser light intensity is measured. At such a time, the laser light intensity increases in proportion to the extent of the deviation between the center wave length of the laser light and the wavelength of the absorbed rays of molecules in the cell 14. Namely, the laser light intensity is measured to detect the correla tion between the center wavelength of the laser light and set wavelength. Fur ther, a signal processing circuit 16 compares the laser light intensity with a reference signal regarding the set wavelength and a signal regarding their differ ence is controlled by the controller 17.

Title: Thermal recorder
Inventor: SATO TATSUO
IPC: B41J29/62
Filed: 1986-09-10
Abstract: PURPOSE:To prevent the breakdown of a thermal head, by providing a paper feed detection means detecting the presence of paper feed and a conduction control means receiving a signal from the detection means and stopping electric conduction to the thermal head in a paper feed stop condition. CONSTITUTION:A period from a point wherein a preceding sprocket hole 7 is detected by a sprocket hole detection circuit 9 to a point wherein a present sprocket hole 7 is detected is calculated. If the period is within a predetermined value, a paper feed is judged to be normal; on the contrary, if the sprocket hole 7 is not detected after the predetermined period is elapsed, the paper feed is not conducted and judged to be in a stop condition or abnormal. If the aforesaid paper feed stop condition is generated in a printing processing, conduction to a thermal head 2 is stopped by a conduction control circuit 13. Namely, a printing action is forcibly stopped. Therefore, even if a recording paper 5 is wrinkled and jammed in the vicinity of a heating portion of the thermal head 2 for some reason or other, the thermal head 2 free from conduction is prevented from being excessively heated and the failure such as breakdown caused by heat fatigue is avoided.

Title: Phase searching system for ink jet printer
Inventor: JINNAI KOUICHIROU
IPC: B41J2/115
Filed: 1981-12-28
Abstract: PURPOSE:To miniaturize the quipment by starting a printing when the phase number searched at the preceding searching time coincides with the phase number searched at each start of the carriage by allowing a margin for the comparison of the phases. CONSTITUTION:When a carriage stops at the start of printing, the phase thereof is searched and memorized in a B register of a microcomputer. Then, the carriage starts operation under the control of a pulse motor and when it reaches the printing position, the phase number is searched and compared with the contents of the B register. If the phase number searched at the printing position is within a range of the contents thereof, a printing starts with a judgement that the coincidence takes place. If it is not within the range, the carriage is returned ahead of the start point and the printing is on standby until it stops completely. Subsequently, the phase searching is conducted to start the carriage again for printing.

Title: Fuel control device for engine
Inventor: FURUTA KOICHI
IPC: F02D41/06
Filed: 1991-08-27
Abstract: PURPOSE:To provide a fuel control device for an engine in which the amount of fuel especially at start after the re-starting is compensated to improve the startability of the engine. CONSTITUTION:After an engine 11 is started, a previously started flag BBFST is judged at step 101 to judge that the engine was stopped immediately at the previous start. To discriminate that this start is the start after re-starting, they are judged at step 102 and step 103 that the water temperature THW at the water temperature sensor 17 is higher than the set value (alpha) and a difference between this time water temperature and previous water temperature is smaller than (gamma), respectively. Then, when the start after re-starting has been discriminated, a start pulse width f (THW) based on the water temperature is reduced for compensation with a coefficient of f (RS) to prevent the fuel from becoming over-rich at this start after re-starting. Thus the startability of the engine 11 is improved.

Abstract: PURPOSE:To decrease the weight of an electrode plate group while maintaining the plates in good contact with each other by making a plastic bar to penetrate through the current collecting lags of the plates which are made of grids prepared from an acid-proof plastic. CONSTITUTION:After a thin lead film layer 4 is fixed to a grid-like base 3 made of an acid-proof plastic, an active material 5 is provided over the layer 4 so as to make an electrode plate 1. Next, plural pieces of plates 1 are positioned parallel to each other, and a bar 7 made of a plastic is made to penetrate through the penetration holes 6 of current collecting lags 2 so as to join the plates 1 into a given plate-group shape. After that, the lags 2 are immersed in molten pure lead having a temperature of below 350 deg.C for 0.2-1sec. As a result, since molten lead is instantaneously deprived of its heat due to the lags 2 and the bar 7 to solidify, the bar 7 and the lags 2 can be fixed together. Consequently, the electric connection among the plates 1 can be secured while realizing weight reduction by use of the plastic member.

Title: Digital broadcast receiver
Inventor: ADACHI TOSHIMASA

Filed: 1995-08-24
Abstract: PROBLEM TO BE SOLVED: To prevent a signal jumping into a circuit not via a surface acoustic wave filter from giving adverse effect onto substantial signal by providing the surface acoustic wave filter in a tuner containing case and at a post-stage of a frequency conversion means. SOLUTION: A 2nd frequency conversion circuit 68 converts a frequency of a 1st intermediate frequency signal into a 2nd intermediate frequency signal and gives the converted signal to a surface acoustic wave filter 71. Only inputted 2nd intermediate frequency signal passes through the filter 71 so as to attenuate sufficiently other signal component adjacent to the channel, the result is amplified by an amplifier circuit 72 and extracted as an output of a tuner section 59. A demodulation section 74 amplifies an output signal from a tuner section 59 by a buffer amplifier circuit 76 and gives the result to an attenuator circuit 77, and when the amplified signal is given to an A/D converter circuit, AGC processing is conducted so that the input level is constant.  In thus case, a level of signals jumping into the succeeding circuits not via the filter 72 from a pre-stage of the filter 72 keeps the same level difference at all times even when the input signal level is changed when the level is compared with a signal level passing through a regular signal path.
