Title: Ink jet recording head and its manufacture
Inventor: YOKOTA MASAMI
IPC: B41J2/16
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To control a thickness of solid layers of a photosensitive resin to predetermined range and form many nozzles in a high density by setting a compatibility prevention layer and a light shielding layer between a first photosensitive resin layer for forming a channel and a second photosensitive resin layer for forming a liquid chamber. SOLUTION: Solid layers 4 and 7 which occupy a part to be a channel and a liquid chamber are formed on a substrate 1 having a discharge pressure generation element 3. A resin 10 of a type set at ordinary temperatures which becomes a wall of the liquid channel is layered or filled and set. Then, part of the solid layers 4 and 7 is removed. The ink jet recording head is manufactured in this manner. In forming the solid layers 4 and 7, after the first photosensitive resin 4 is layered onto the substrate 1, the solid layer is selectively exposed to leave a part which occupies the part to be the channel and liquid chamber, whereby a latent image is formed. Thereafter, a compatibility prevention layer 5 and a light shielding layer 6 are sequentially layered, and then the second photosensitive resin layer 7 is formed and similarly selectively exposed to form a latent image. Both photosensitive resin layers 4 and 7 are then developed.

Abstract: PROBLEM TO BE SOLVED: To make lightweight, give high tension characteristic, and suppress increases in dip at high temperatures and fatigue failure in actual work by covering the outside of a matrix made of a fusible metallic material, in which long fibers are buried as a reinforcing material with an aluminum base or copper base material. SOLUTION: Long fibers of preferably polyparaphenylene benzobisoxazole fibers which show negative coefficient of linear expansion, which are lightweight and have appropriate strength, and thereby, high strength, high elasticity, high heat resistance, and high flame resistance are obtained. A fusible metallic material is preferably selected from among Zn, Bi, Tl, Sn, Pb, and their alloy, having a melting point of 300 deg.C or lower and suitable for soldering. In order to prevent a drop in strength, the volumetric occupying ratio of long fibers in a complex material with the fusible metal material is set to 15-90%. The fusible metallic material covered with a copper base material having high melting point is melted or softened when the temperature of an electric wire, is raised, force of constraint with the long fibers is weakened, and thermal stresses between them are relaxed.

Abstract: PURPOSE:To restrict the short channel effect of a semiconductor device that has a channel stopper below a field oxide film by forming the channel stopper by effecting ion implantation before and after the formation of the field oxide film. CONSTITUTION:A pad SiO2 film 12 and a polycrystalline Si film 13 are laminated on the surface of a Si substrate 11, and a non-oxidizing Si3N4 film 14 is formed on the film 13. A BF2 ion 15 is implanted using the film 14 as a mask. In succession, a field oxide film 16 is formed in an element isolation region to separate the films 14, 13, 12, and a gate SiO2 film 17 is formed at that part. Thereafter, there are implanted B ions 21 by the use of the film 16 as a mask, the ions serving as channel stopping and punch-through-prevention. For this, an amount of the ions implanted before formation of the film 16 is reduced compared with a case where the ions are implanted at a time before the formation of the film 16. Therefore, the degree of ion diffusion from the film 16 into the element formation region is reduced, and hence a desired semiconductor device with restricted short channel effect is formed.

Title: Thyristor
Inventor: YUKIMOTO YOSHINORI
IPC: H01L29/744
Filed: 1979-10-02
Abstract: PURPOSE:To contrive the increase in the operating speed of and withstand voltage of a thyristor by forming a p type conductivity type gate region adjacent to a p type conductivity type base layer in an n type conductivity type base layer and an auxiliary thyristor between the gate electrode and the cathode electrode and limiting the hole injection amount from the anode layer to the n type conductivity type base layer. CONSTITUTION:In an auxiliary thyristor 11 are formed a cathode region 12 having equal impurity density to a cathode layer 4 around a gate electrode 7 and an auxiliary gate electrode 13 on the surface of the region 12. The thickness WB of the p type conductivity type base layer 3a is so determined as to satisfy the relation of Nd.a<2Na.WB<2> between the mutual interval 2a of the gate regions 9 and the impurity density Na of the layer 3a, the impurity density Nd of the n type conductivity type base layer 1. Since higher density n<+> type conductivity type base region 10 than the base layer 1 is formed between the layer 1 and the anode layer 2 in case that reverse bias voltage is applied between the cathode electrode 6 and the anode electrode 5 in cutting off the current, this limits the hole injection amount to the base layer 1 from the anode layer 2, thereby suppressing the hole injection amount to minimum.

Title: Manufacture of sliding valve made of synthetic resin
Inventor: SASAO ISAMU
IPC: B29C45/14
Filed: 1985-06-12
Abstract: PURPOSE:To provide a sliding valve made of synthetic resin which is favorable in dimensional accuracy and is, moreover, compensated from a strength point of view also, by molding a synthetic resin material on the circumference of a core metal member of sliding valve composed of a metallic material. CONSTITUTION:A core metal member 1, for example, possesses curved parts on both sides of the same, which is approximated to a form of a sliding valve whose cross section is in what is called an oval state obtained by communicating curved parts by linear parts with one another and the same is manufactured of a metallic material such as aluminum or a steel plate, in the sliding valve of a sliding throttle valve type carburetor. The core metal member 1 is arranged within a mold of an injection molding machine by inserting the core metal member 1 within the mold and then molding is performed by injecting a synthetic resin material on the circumference of the core metal member 1. Dimensional accuracy of the title valve becomes extremely favorable as a thickness of the synthetic rein material can be made into about the same at each of parts of the sliding valve when the core metal member is formed into about the same form with the sliding valve in whatever complicated form the sliding valve may become. Strength and rigidity of the sliding valve can be improved as compared with that made of only synthetic resin material as the core metal member 1 has been arranged.

Abstract: PURPOSE:To facilitate understanding of the status of the deterioration of a semiconductor device with a high reliability by a method wherein corrosion of Al caused by penetration of external moisture into the semiconductor device is detected from the change of the inversion state of an internal signal line. CONSTITUTION:The output Al of DFF 3 is connected to the input D of DFF A and the output (inverse Q) of DFF 4 is connected to the input D of DFF 3 through a signal line 7 made of Al. The data of DFF 3 is transferred to DFF 4 every time the effective edge of a clock is inputted to realize a shift register operation. On the other hand, the data of DFF 4 is inverted and then transferred to DFF 3. With this process, a signal line 11 repeats an inversion operation in accordance with the input of the clock. If the signal line 7 made of Al is deteriorated and disconnected, the data of DFF 4 is not transferred to DFF 3. Therefore, the data on the signal line 11 is different from the data of the inversion operation before the disconnection of the signal line 7. With this constitution, the deterioration of a semiconductor device can be detected.

Title: Expansion valve
Inventor: HIROTA HISATOSHI
IPC: F25B49/02
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To control the flow rate of refrigerant approximately corresponding to the temperature of the refrigerant sent from an evaporator by disposing a temperature sensitive chamber at the outlet of an air stream flowing along heat transfer fins of an evaporator, where a valve body is driven by a diaphragm forming a part of an airtight wall of the temperature sensitive chamber. SOLUTION: In an expansion valve 20 which is used together with an evaporator in a refrigeration cycle for an air conditioner of automobile, high pressure refrigerant is sent from a high pressure refrigerant inlet 22 toward a refrigerant outlet 23 to feed the refrigerant into the evaporator, while the refrigerant is being adiabatically expanded at a throttling orifice 24, and a valve body 25 is displaced corresponding to the pressure in a temperature sensitive chamber 30 through a diaphragm 31 to vary the flow rate of the high pressure refrigerant. In this case, the chamber 30 is provided on the outlet side of a refrigerant passage of the evaporator so as to be positioned in an air flow caused to flow by an air fan along heat transfer fins of the evaporator.  As a result, the temperature of the air sensed by the chamber 30 can be made nearly equal to the temperature of the refrigerant coming to the outlet 23, and hence the flow rate of the high pressure refrigerant sent into the evaporator can be controlled accurately.

Filed: 1988-05-25
Abstract: PURPOSE:To inexpensively realize a driving circuit having a high speed, a low loss and less noise by synchronizing a chopping frequency for maintaining a current constant with an external clock. CONSTITUTION:A voltage V1 generated at a current detecting resistor 3 is applied to one input terminal of a comparator 5, and the voltage Vref of a reference power source 4 is applied to the other input terminal. When the voltage V1 exceeds the voltage Vref, driving means 6 turns OFF switch means 2, and holding means 7 holds the state of the comparator 5 in a state that the voltage V1 exceeds the voltage Vref. When a clock signal is input to the base of a transistor 8, the means 7 is reset, and the switch means is closed. Thus, the ON period of the switch means is synchronized with the clock signal.
