Title: Print form for non-impact magnetic ink character printer and preprocessing of printing form in non-impact magnetic ink character printer
Inventor: NOZU TOSHIYO
IPC: B41J13/02
Filed: 1989-11-11
Abstract: PURPOSE:To enable uniform attachment, transfer and fixing of ink or toner by smoothing a specified printing plane using a surface smoothing device consisting of devices such as pressure, heating and friction sliding and making the specified printing plane smooth, embossed with a step of almost the same as a character layer thickness. CONSTITUTION:Any appropriate heating temperature and pressure force are set for a head 3 and a form 5 is fed by a platen feed roller 2. Subsequently the friction sliding action caused by the platen feed roller 2 and the head 3, and also the pressure action by the rotating platen feed roller 2 and the stationary head 3 work almost simultaneously to smooth the specified printing plane 5a. In addition, the heating action caused by a heating element in the head 3 and the friction sliding action press the smoothed specified printing plane 5a in a thickness direction. This pressure rubs, squashing the plane 5a and forms an embossed, smooth specified printing plane 5a with a specified step, compared to the surface of the unprinted plane 5b with the head 3 does not come in contact. In this way, the specified printing plane 5a is smoothed to allow uniform transfer of ink.

Title: Digital signal transmitting device
Inventor: TAKAI HITOSHI
IPC: H04L27/22
Filed: 1985-12-26
Abstract: PURPOSE:To prevent the occurrence of waveform distortion due to a multi-path by mounting and transmitting alternately the same data to the first and second frequencies. CONSTITUTION:The data are differentially coded beforehand and applied to a data input terminal 1. The first oscillator 3 generates the sine wave of a frequency f1 and the second oscillator 4 generates the sine wave of a frequency f2. Balance modulators 5 and 6 balance-modulate the input data with above- mentioned frequencies f1 and f2. A changing-over switch 7 selects alternately the output of both modulators 5 and 6, and sends the signal modulated by the f1 at the first half part of the same time slot and by f2 at the last half part to an output terminal 8. At the receiving side, a receiving signal is separated with the frequency, the first half part is delayed by the half time slot and the last half part is synthesized. Thus, since the part overlapped by the direct wave is decreased even when the delaying wave exists, the occurrence of the distortion due to the multi-path can be prevented. The frequency and the time diversity effect can be obtained.

Title: Misfire detecting device
Inventor: SUGIMOTO HIROYASU
IPC: G01M15/00
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous detection by accurately detecting the occurrence of a misfire even at traveling time, by correcting a judging value used to judge the misfire on the basis of the transmission ratio of a shift means at traveling time, and judging the misfire by the judging value after correction. SOLUTION: An ECU 22 calculates a rotational fluctuation quantity on the basis of a signal from a rotation sensor 17, detects a shift position (the transmission ratio) of a transmission 21 on the basis of a signal from a shift position sensor 23, and corrects a misfire judging value according to the detected transmission ratio. This correction is made by multiplying the misfire judging value of a reference by a correction factor determined on the basis of function data (a map) of the shift position and the correction factor. The ECU 22 judges that a misfire is caused when the rotational fluctuation quantity exceeds the misfire judging value after correction. Thus, a detecting rate at misfire time is improved, and the misfire is detected with high accuracy to accurately prevent erroneous detection at normal time.

A memory diode 36 which is a high capacity element of 1.8F is generally charged at a level corresponding to these integration curve and retains charges over a long term thus retaining the net current flow-in level from the battery 10 correctly.  Consequently, the monitor 16 monitors the applying/ discharging current of the battery 10 during operation and can indicate the charged state correctly.
