Title: Liquid crystal type projector
Inventor: UCHIDA MINORU
IPC: G02F1/1335
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to effectively shield heat, to reduce the number of parts of the device and to reduce a parts purchase cost and assembly cost by forming an aperture of ceramics. SOLUTION: Light 11 emitted from a light source 10 arrives at a liquid crystal panel 12 after the unnecessary light is removed therefrom by a box type aperture 1 made of a ceramic. The aperture 1 is made of the ceramic by which the light energy emitted from the light source 10 will not reduce a high temperature, and smaller the thermal conductivity will be small. A resin case 31 is, therefore, hardly adversely affected and eventually the reduction in the size of the aperture 1 and the number of parts is made possible. More particularly the ceramic aperture 1 is formed to a box shape, by which the heat transfer distance A to the resin case 31 is made larger and the thermally insulating effect higher. Alumina, forsterite, etc., are used alone or as their mixture for the material of the ceramics and further, are used by adding other additives thereto.

Abstract: PURPOSE:To enable the prevention of clogging along with a smooth discharge of bubbles by providing a head holder having a check valve in an upper counterflow passage and a head having a bubble discharge channel to introduce bubbles being trapped. CONSTITUTION:In order to discharge bubbles mixed-in from outside through a tube due to a prolonged unused state without printing or those mixed from a ink feed needle during the loading or unloading of an ink cassette, a cap 36 puts on a nozzle section at the home position.

Title: Power source unit
Inventor: OZAWA SHINSUKE
IPC: G05F5/00
Filed: 1986-06-25
Abstract: PURPOSE:To use without conscious of the kind of a power source voltage system by making on/off a changeover switch for making voltage doubler connection according to the result of judgement of a means that judges whether an AC power source is a 100V system or a 200V system. CONSTITUTION:When an AC power source is a 100V power source, voltage Ed showing AC 100V is generated at a common junction of resistors R1, R2. A judging means CMP compares the voltage Ed1 and reference voltage ER, and when Ed1<ER, outputs a signal that makes a switch SW1 on. When the switch SW1 is made on, a changeover switch SW0 becomes on, and thereby, a rectifier and smoothing circuit 4 becomes voltage doubler rectifying connection. In the case where the power source 1 is a 200V system power source, voltage Ed2 that shows AC 200V is generated at the common junction of resistors R1, R2. The means CMP compares this voltage Ed2 and voltage ER, and outputs a signal that makes the signal SW1 off when Ed2>ER. When the switch SW1 is made off, the switch SW0 becomes off, and the circuit 4 acts as wave generation rectifying connection.

Title: Substrate device equipped with surface-mounting type electronic parts
Inventor: USUHA TAKASHI
IPC: H05K1/18
Filed: 1987-06-16
Abstract: PURPOSE:To prevent one side startup of electronic parts, namely, a phenomenon known as Manhattan by forming an electrode part at both end sides of the flat shaped main frame of the electronic parts and, further, by forming solder resistance layers so that they may cover a part of the above electrode part. CONSTITUTION:Surface-mounting type electronic parts 1 are composed of a main frame 2 and electrode parts 3 and 4 located at its both ends and solder resistance layers 11 and 12 are formed so that upper parts of the electrode parts are covered by the above layers at least. Acrylic and epoxy resins or ultraviolet-setting type resins, ceramics, and glass are used at the solder resistance layers and their layers are formed by replication or screen printing. When difference in rise and fall of a reflow temperature develops between the electrode parts 3 and 4 and only a paste of solder 8 at one side of the electrode part 3 is melted, molten solder adheres only at the surface of electrode part 3 other than the solder resistance layers by the presence of the solder resistance layer 11. A moment based on surface tension in the direction as indicated by the arrow interacts at the electrode part 3 by the adhesion of molten solder and its direction makes an obtuse angle with respect to the flat face of electronic parts 1. Thus, a rotation moment (a perpendicular component force) centered on the electrode part 3 for the parts 1 is extremely reduced and then a Manhattan phenomenon is not observed at all.

Abstract: PROBLEM TO BE SOLVED: To reduce the vibration of a movable separating membrane at the time of break of a bubble, to obtain a stable discharge, to facilitate also supply of a liquid and to improve a characteristic of refilling, by suppressing the retrogression of a meniscus by a regulating member in relation to the displacement of the movable separating membrane corresponding to the growth and contraction of the bubble. SOLUTION: A first liquid passage 3 communicating with a discharge orifice 11 and a second liquid passage 4 having a bubble producing region 30 are separated from each other by a movable separating membrane 5. A movable member 26 is provided so that it faces a heater 2 and the free end 28 thereof is positioned just above the discharge orifice side end of the heater 2 with the movable separating membrane 5 between them. When the heater 2 produces a bubble 40, the free end 28 of the movable member 26 is displaced in a large degree and also the movable separating membrane 5 expands to a large extent to the discharge orifice 11 side. Thereby discharge efficiency is improved. In a process of contraction and break of the bubble 40, the movable separating membrane 5 and the movable member 26 separate from each other and a liquid 150 comes to be present between them and draws in a meniscus 141 to a large extent. The liquid 150 functions as a damper or a cushion and thereby the spring vibration caused by the movable separating membrane 5 can be damped more speedily.

IPC: G11C11/417
Filed: 1981-09-24
Abstract: PURPOSE:To improve the reliability, by connecting a control transistor (TR) to at least one of a word line and a data line of a memory matrix and taking a potential other than a signal potential controlling the memory matrix. CONSTITUTION:Control TRs 33, 34 are connected to a word line 9 or data lines 10, 11 of a memory substrate 32 locating a memory cell in matrix and a bistable terminal voltage of a flip-flop circuit of the memory cell and each line potential are sufficiently taken larger than a high voltage applied to the board. Thus, a capacitance between a gate 35 of the control TR and the substrate 32 is taken sufficiently larger, allowing to obtain sufficiently high gate potential when the high voltage is applied to the board. Thus, the gate of the control TR is charged before the high voltage is applied to the memory substrate 32, the word line and the data line are kept to the substrate potential and the reliability can be improved.
