Title: Feed speed control device for recording media
Inventor: KAWABE SADANOBU
IPC: G11B15/087
Filed: 1978-07-20
Abstract: PURPOSE: To make the tape speed of reproducing equal to that of recording by using the signal, which has the same duty as that of the control signal recorded in a recording medium, generated in a control signal reproducing circuit.

Filed: 1993-04-15
Abstract: PURPOSE:To improve tracking performance corresponding to the change of a curved passage. CONSTITUTION:The deviations d-L1, d-L2 between the extending line O of the center of a vehicle and an objective course passing through the center of the vehicle are computed at a near watching position L1 and a far watching position L2, further a estimated course of the vehicle at the respective watching position L1, L2 are computed out of steering angle, vehicle speed, etc., and the deviations epsilon-L1, epsilon-L2 between the estimated course and the objective course are computed. When the deviations d-L1, d-L2, epsilon-L1, epsilon-L2 are small, it is judged to be a straight passage or a gentle curved passage, so as to control the steering angle by using a primary estimating steering angle equation. When the deviations d-L1, d-L2 are large and epsilon-L1, epsilon-L2 are small, it is judged to be a steady curved passage, so as to control the steering angle by using a secondary for point steering angle estimating equation. Meanwhile, the deviations are different from above cases, it is judged to be a passage changing from a straight passage to a curved passage or a curved passage S-likely largely changing the direction, so as to control the steering angle by using a secondary near point steering angle estimating equation.

Filed: 1978-07-22
Abstract: PURPOSE: To obtain a highly accurate mask pattern by adopting a plasma-spattering double etching method to form openings in a spacer film.  
     CONSTITUTION: A spacer film 8 made of an isotropic inorganic compound or a heat resisting organic compound with a thickness of 0.4μm or more, is formed on an under-ground film 7 that is provided on a semiconductor plate 1. A metal film pattern 5 to be used as a mask, is formed with an arbitrary method on the spacer film 8 to where openings are made by means of a plasma-spattering double etching method. Then a thick metal film 4 that is as thick as the spacer film pattern is laid, and leaving the spacer pattern, unnecessary sections of the metal film pattern and metal film are removed to form a thick metal pattern 4. Thus by adopting the plasma-spattering double etching method to form openings in the spacer film, a thick metal film pattern with a thickness of aproximately 1μm can be obtained.

Title: Control device for hot water supply machine
Inventor: ASANO KAZUTAKA
IPC: F23N5/14
Filed: 1986-04-16
Abstract: PURPOSE:To shorten the warming-up time of a hot water supply machine by carrying out setting-change PID calculation when setting a high temperature and for other settings carrying out ordinary PID. CONSTITUTION:A control section 1 lets an ignition device 2 ignite, opens a gas proportional valve 3 to ignite a main burner 4, and detects ignition by an ignition detection circuit 5. Water in a heat exchanger 6 is changed to hot water by the main burner 4, and the control section 1 senses the temperature of the hot water at present by an out-going water thermistor 7 and controls the gas proportional valve 3 so as to bring the hot water temperature to a temperature set by an out-going water temperature setting section. Right after starting use of the machine, high temperature setting is judged at A, and if high temperature setting is judged, the control moves to setting-change PID calculation and the integration calculation is stopped to prevent overshoot. On the contrary if low temperature setting is judged, calculation is carried out by ordinary PID to shorten the warming-up time.

Title: Oxygen density detecting apparatus for burner
Inventor: YAMAGUCHI HIROSHI
IPC: G01N27/62
Filed: 1980-07-01
Abstract: PURPOSE:To perform accurate detection of oxygen densities corresponding to various kinds of burners by a method wherein an ion current which is almost stabilized after the formation of a flame in each of the burners is stored and is compared with a constantly supplied ion current and the density of oxygen included in combustion air is detected in accordance with the difference between the stored ion current and the constantly supplied ion current. CONSTITUTION:When a heater is ignited, a flame is generated on a burner head 1 and an ion current flows from the burner head 1 to a from rod 2. Such ion current is converted into a voltage signal A through a resistor 5 and the signal A is further converted into a voltage signal B through a protective resistor 6 which signal B is then applied on a microcomputor (muCOM) 9. The microcomputor 9 stores an ion current flowing after a predetermined time interval (that is, after a lapse of a predetermined time in which the ion current is stabilized) and the stored ion current and the ion current flowing from the burner head 1 to the frame rod 2 are compared with each other. Thus, when it is detected that the difference between the above two ion currents has reached a predetermined value, a signal D is generated from the microcomputor 9 to thereby alarm that the heater is short of oxygen.
