Title: High speed recalling non-volatile ram
Inventor: NODA MASAMI
IPC: H01L29/792
Filed: 1985-05-15
Abstract: PURPOSE:To make a recalling action easy and to execute a high integration by presetting the condition of SRAM from a hit line and an inverting bit line. CONSTITUTION:When a bit line BL comes to be 'H', and -BL comes to be 'L', the contact (q) of a SRAM is precharged to the level of VDD-VTH. After that, when electronic parts are accumulated at a non-volatile floating gate 8, an FET 7 comes to be off. When a terminal VRC is made to rise, the contact (q) comes to be 'H' and the information of a gate 8 is transferred to the SRAM. In the same way, when the electron is short at the gate 8, the FET 7 comes to be on, and when the terminal VRC is made to rise, the contact (q) comes to be 'H', the contact -q comes to be 'H', and the information of the gate 8 is transferred to the SRAM.

Title: Control device for instantaneous hot water boiler
Inventor: MURAKAMI HIROKUNI
IPC: F23N5/24
Filed: 1986-05-06
Abstract: PURPOSE:To prevent an excessive cooling of a heat exchanger by a method wherein a controlling means for setting a speed of a combustion fan in response to an air feeding temperature after a hot water feeding operation is terminated. CONSTITUTION:When a water plug 4 is closed at a time t1, a burner 5 is shutdown by a turned-off state of a water flow switch 9, only a combustion fan 8 is stopped while it is delayed up to a time t2. At this time, the number of rotation of a combustion fan 8 is set by a value of air feeding temperature taken through an air feeding temperature sensor 11 and a sensor circuit 12. That is, in case that a hot temperature is experienced in surrounding atmosphere in summer season, the number of rotation of a combustion fan is increased and in turn in winter season, the number of rotation of the fan is decreased. In this way, since an amount of blown air is set in response to an air feeding temperature of a combustion fan, an excessive cooling of the heat exchanger is not carried out and so there is no possibility that an abnormal cold water feeling in case of refeeding of hot water or a freezing of water in winter season is encountered.

Abstract: PURPOSE:To make air jet from the whole peripheries of a valve and valve seat of intake and exhaust valves to prevent the deposit of carbon or the like during the running of an engine by providing a hole in the valve seat and providing a skirt on the valve to constitute a path. CONSTITUTION:Air forced from a compressed air supply device to an air supply hole 9 enters air reservoirs 11, 12, 13 through a air path 10. In operation of intake and exhaust valves, compressed air to a valve 3 is jetted from the whole periphery of the valve 3 through a path 5 when an air hole 7 provided in a skirt 4 is opened to the air reservoirs 11, 12. Compressed air to a valve seat 1 is jetted from the air reservoir 13 through a hole 2 provided in the whole periphery of a valve seat 1 when the valve 3 begins to open and continuously jetted until the valve 3 is closed. Thus, the valve 3 and valve seat 1 are prevented from dirt.

Title: Water quality meter applying biosensor and buffer solution therefor
Inventor: TAGUCHI KAZUYUKI
IPC: G01N27/416
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To provide a stable eco-friendly water quality meter applying biosensor by solving such a problem that the phosphoric acid contained in a used buffer solution reacts to calcium ions contained in water to be inspected and the resulting insoluble calcium phosphate of the reaction blocks a channel or adheres to an immobilizing film, resulting in the deterioration of the responsiveness or measuring sensitivity of the meter. SOLUTION: A water quality meter uses a sodium tetraborate solution doped with iron ions and magnesium ions as a buffer solution. Since the buffer solution does not contain any phosphoric acid ion, no deposit (calcium phosphate) is produced even when the buffer solution is mixed in water to be inspected at the time of measurement. Therefore, the blockage of a channel or adhesion of deposits to a microorganism immobilizing film does not occur and the water to be inspected can be monitored for a long time regardless of the hardness component of the water.

Abstract: PURPOSE:To obtain a good reproduction picture in variable reproduction speed from still to 3 times, by combining a still, two-time speed, and three-time speed with a normal reproduction speed to realize a variable speed reproduction, and by switching properly a main and an auxiliary rotary heads at the time of special reproduction. CONSTITUTION:The figure (a) shows the state in which track patterns are repeatedly arranged, and a heavy line in the figure shows a head locus at the time of reproduction with 0.5-time speed. Movable pieces of switches 44 and 45 are connected to an X side when a switching pulse is of an H level, and to a Y side when being of an L level. They are connected to the Y side when a main and auxiliary rotary heads switching signal shown in the figure (d) is at the H level, and connected to the X side at the L level. Thus, a track of even number is reproduced when the switching pulse does not agree with the head switching signal, and a track of an odd number is reproduced if they agree each other. To realize 0.5-time speed, a speed switching signal generator 10 receives a signal from a waveform processing circuit 20 to outut a normal indication signal shown in the figure (e) and a still indication signal shown in the figure (f). Since the main and auxiliary rotary heads are timely switched by the head switching signal (d), a reproduction envelope shown in the figure (b) at this moment does not lower, and a picture is in good state.
