Title: Ceramic substrate with breaking groove
Inventor: WASHINO JUNICHI
IPC: H05K1/02
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a large ceramic substrate, which is unlikely to have cracks, except intended grooves, during a sintering process so that it can be divided into a predetermined number of pieces in a reliable manner. SOLUTION: A large ceramic substrate 1 including dummy areas 2a has breaking grooves 3 across it and notches at regular intervals of (k) at both side edges. Each pair of the notches at opposite side edges are aligned with one of the grooves 3 in each interval (k). Therefore, it is easy to break the ceramic substrate 1 along the grooves aligned with the notches even if the ceramic substrate has cracks occurring in the sintering process.

Title: Method for driving display device
Inventor: TAKEDA YOSHIYA
IPC: G02F1/1368
Filed: 1989-11-28
Abstract: PURPOSE:To reduce power consumption and to improve the picture quality by transmitting a picture signal to a pixel electrode during and on-time of a switching element and imparting modulation signals having different polarities during the off time at every field. CONSTITUTION:A picture signal voltage is transmitted to the pixel electrode during the on-time of the switching element 3 of a thin-film transistor, and modulation signals having the same absolute value and different polarities are transmitted to the first wiring at every field during the off-time 3. Consequently, the potential of the pixel electrode is changed, the potential change and the picture signal voltage are superimposed or cancelled, and a voltage is impressed on the display material. Accordingly, only the necessary minimum pixel signal is transmitted, hence the output signal of a signal driving circuit is drastically reduced, power consumption is also reduced, flickering is diminished, and the display picture quality is improved.

Title: Detector for setting error of input signal selection
Inventor: TAMADA TAKUMA
IPC: H04N9/79
Filed: 1987-12-07
Abstract: PURPOSE:To detect the setting error of an input selecting section for inputted signals by detecting the kind and state of the input signals and collating and collecting those information and the setting state of the selecting section by a logic circuit. CONSTITUTION:Since output signals from the terminal (a) of a synchronizing signal detector 1 are composite signals or luminance signals, a detection signal of 'no synchronizing signal L' is outputted when neither the composite signals nor the luminance signals are inputted. A burst detector 2 is used for detecting the presence/absence of a burst signal in the output signals from the terminal (a) and, when the output signals from the terminal (a) are composite video signals, the output of the detector 2 becomes high in level. When the output signals from the terminal (a) are luminance signals, the detector 2 outputs a detection signal of 'no burst L', because no burst signal exists. Moreover, a logic circuit composed of OR circuits 4-7 and an AND circuit 8 collates results obtained from the above-mentioned detect signals with the setting state of a signal selecting section and performs operations for implementing a signal of 'setting error L'.

Title: Float valve
Inventor: KOIKE TADASHI
IPC: F16T1/24
Filed: 1988-12-08
Abstract: PURPOSE:To simplify construction and enable the improvement of sealing characteristics at the time of closing both valve seats by applying the constitution wherein one end of a lever opens the second valve port after a float opens the first valve port, and the other end of the lever is so formed as to have the float seat where the float is seated in opening the first valve port. CONSTITUTION:When a liquid level drops due to discharge, a float 24 also comes down and a lever 28 turns in a valve close direction, thereby making a valve body 32 close the second valve port 18 and stopping a flow of condensed water. In this case, the valve body 32 is closed due to a pressure differential between primary pressure within a valve chamber 6 and secondary side pressure at an outlet 12. Further, when a liquid level drops within the valve chamber 6, a float 24 comes down and closes the first valve port 14, thereby stopping completely the outflow of condensed water. In this case, the float seat 28b of the lever 28 is in parallel to the center axis of the first valve port 14, concentric with the center axis of the first valve port 14 and formed in two rows on a cylindrical surface having a radius corresponding to the size of the float 24. Consequently, the float 24 as lowered comes in contact with the float seat 28b and concurrently is seated on the first valve seat 16, thereby completely closing the first value port 14.

Title: Touch coordinate detector
Inventor: KIMURA MASATSUGU
IPC: G06F3/041
Filed: 1988-12-09
Abstract: PURPOSE:To prevent the erroneous detection of contact position coordinates due to the influence of a flaw, etc., on a resistance film by connecting a first power source terminal through a resistor to one terminal, connecting a second power source terminal to the other terminal and providing a voltage measuring circuit to measure the terminal voltage of the resistor. CONSTITUTION:For example, the flaw, etc., is attached in a position shown by X on a resistance film 3. The resistance value of the resistance film 3 is made high by DELTARx by the flaw, etc., and goes to be (Rx+R1-x+DELTARx). On the other hand, since the resistance value of a resistor 1 is R0 and fixed, the terminal voltage of the resistor 1 goes to be R0.Vcc/(R0+Rx+R1-x+DELTARX) and it is a reference voltage. Thus, an alarm signal is generated by a voltage measuring circuit 4 and supplied to an MPU and it is informed of the MPU that the resistance value of the resistance film 3 is changed. Thus, before next impedance measurement is started, the MPU can know that the resistance value of the resistance film 3 is changed.
