Title: Instantaneous hot-water supply device
Inventor: UCHIDA TETSUEI
IPC: F24D3/10
Filed: 1979-02-05
Abstract: PURPOSE: To reduce bubbling noise by a method wherein a feed pipe is communicated with a drum body at its one end and with the inlet side of a radiator at its other end, while a return pipe is communicated at its one end with the outlet pipe of the radiator and communicated at its other end with an upper portion of the drum body apart from said one end of the feed pipe.  
     CONSTITUTION: A circulating pump 14 is fitted to a boiler main body 1 having a small-capacity drum body 6. A feed pipe 12 is communicated with an upper portion of the drum 6 at its one end and with the inlet side of a radiator 18 at its other end. A return pipe 19 communicated at its one end with the outlet side of the radiator 18 is communicated at its other end with an upper portion of the drum body 6 apart from said one end of the pipe 2. Hot water in the drum body 6 is circulated by the pump 14. Since the drum body 6 has a small capacity and hot water is produced instantaneously, bubbles formed in the drum body 6 tend to rise rapidly and collide against the inside surface of the drum body 6 to make noises. However, since the returned hot water flows downward in the drum body 6 to stir the hot water to be discharged, bubble formation and bubbling noises are reduced.

Title: Formation of single crystal thin film and formation of axially oriented polycrystal thin film
Inventor: UEYAMA SUMIYOSHI
IPC: C30B29/06
Filed: 1995-01-30
Abstract: PURPOSE: To form single crystal thin films on a substrate by using a plasma CVD. CONSTITUTION: SiF4 which selectively etches amorphous silicon is supplied together with SiH4 which forms silicon from a reactive gas supply pipe 13. The mixed phase silicon thin films in which the amorphous silicon phase and the fine crystal silicon phase grow on the substrate 11 by progression of the plasma CVD. The mixed phase silicon thin films under growth are irradiated with an Ne beam formed in a plasma chamber 4. This Ne beam is cast to the mixed phase silicon thin films from plural directions perpendicular to the plural most closed packing surface of the single crystal silicon by the effect of a reflection plate 12. The mixed phase silicon thin films under growth are, therefore, converted successively to the single crystal Si thin films.  Since the crystallization in the mixed phase silicon thin films is accelerated by the effect of the SiF4 , the formation of the single crystal Si thin films is efficiently realized.

IPC: G01N21/17
Filed: 1980-02-05
Abstract: PURPOSE:To enhance the stability and take out a signal correctly even in the environment of strong electric field by changing coupling coefficient between optical fibers in accordance with humidity by using a hygroscopic substance which swells through absorption of humidity. CONSTITUTION:A light emitted from a light source 6 is introduced into an optical fiber 1a by a microlens 2c. This light goes out into air from the other end of the optical fiber 1a, passing through another microlens 2a and forming nearly parallel beams. The light beams are led to an optical fiber 1b by the other microlens 2b and reaches a photoreceiver 7. A fixation material 4 fixing the optical fiber 1b is swollen when absorbing humidity and thereby the luminous energy entering the optical fiber 1b is changed. Accordingly, by measuring the strength of the incident light in the photoreceiver 7, the humidity can be detected.

Abstract: PROBLEM TO BE SOLVED: To efficiently perform correction of a work plan by calculating the completion estimating time of the work process by a computer on the basis of the number of work completed parts to the present time, comparing the estimating time with the completion scheduled time of the work process by the computer, and extracting the delay process. SOLUTION: Whether the work process is in the completion state or in the performing state is judged (52) by referring to the progress state field of an experience table. When it is judged that the work process is still in the performing state, whether the experience information of the work process is entered in the experience table or not is judged (57). When it is entered, the work time from the starting time to the present time of the work process is calculated, the time required for work for each one part is calculated, and the completion estimating time of the work process is calculated on the basis of the result (58). The completion estimating time is compared with the completion scheduled time of a plan table, the delay process is extracted, and alarm display is performed (59, 54). Accordingly, correction of work can be well performed.

Title: Lead frame, manufacture thereof, resin-sealed semiconductor device and manufacture thereof
Inventor: KOGA AKIRA
IPC: H01L23/50
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to deal with a multi-pin structure by narrowing a lead pitch in a lead frame of QFP type. SOLUTION: Since a die pad 20 has a support 30, its end is connected to an insulating substance 31 to be held, a suspension lead can be excluded. Since no suspension lead is provided and an inner lead region has an allowance, the lead-in (arrangement) of inner lead groups 21, 22, 23, 24 is not restricted. Further, the specific part of the groups 21, 22, 23, 24 can be branched and arranged on the adjacent inner lead group region in accordance with the number of the bonding pads of the element to be mounted. Thus, the spread of metal fine wires across the suspension lead of prior art can be eliminated to prevent the decrease in the reliability of a resin-sealed semiconductor device.
