Title: Semiconductor device
Inventor: SATOU SHINICHI
IPC: H01L29/78
Filed: 1981-02-13
Abstract: PURPOSE:To suppress the short-channel effect of an MOS transistor and enable high-speed operation, by contriving a cross section of source-drain diffusion layer. CONSTITUTION:An MOS transistor provides source and drain diffusion layers 2a, 2b, a gate electrode 3, and a gate oxide film 4 on a semiconductor substrate 1. A source and a drain are diffused doubly in it. A cross section of diffusions 2a', 2b' in contact with a channel region is formed to deepen gradually and continuously from the channel region 5. And a channel length (b) between the deeper diffusions and a channel length (c) between the shallower diffusions in contact with the channel region 5 are obtained. Their relationship is b>c. This establishes the channel lengths (b) and (c) independently. The stabilization of threshold voltage and high-speedness can be achieved simultaneously.

Title: Semiconductor nonvolatile memory and manufacture thereof
Inventor: HIRAI YOSHIO
IPC: H01L29/792
Filed: 1986-02-03
Abstract: PURPOSE:To reduce a writing voltage by increasing the thickness of an insulating film between the side wall of a floating gate electrode and a selective gate electrode, and decreasing the thickness of a superposed portion of the floating gate electrode and the selective electrode, and reducing a capacity between the floating electrode and the selective electrode. CONSTITUTION:To improve writing characteristic, the thickness t1 of an insulating film between the side wall of a floating gate electrode 3 and a selective gate electrode 5 is extremely reduced to approx. 300Angstrom  or lower. The thickness t2 of an insulating film of a superposed portion A of the electrodes 3, 5 is sufficiently increased 1,000Angstrom  or more as compared with t1. Accordingly, a capacity CSP between the electrodes 3 and 5 is extremely small. Thus, the potential of the electrode 4 is hardly affected by the influence of the voltage applied to the electrode 5 to improve the controllability of the potential of the electrode 4 due to the electrode 6, and a writing voltage applied to the electrode 6 can be reduced.

Filed: 1986-02-03
Abstract: PURPOSE:To achieve a simple construction and low cost while facilitating the operation and maintenance, by adjusting a screw fitted with a shaft driven to be rotated and the position of a pin of a link mechanism engaged therewith to swing a wave making board. CONSTITUTION:When an adjusting pin 36 is lowered and a motor 22 is rotated, a screw 23 reciprocates a longitudinally together with the upper end of an upper lever 25 and as the lever 25 turns clockwise on a shaft 27, the top of a wave making board 17 moves forward through a link 28. As the lower end O of the wave making board 17 will not be displaced by the setting of the position of the pin 36, the wave making board 17 performs a flap type swinging. As the upper and lower links 28 and 31 moves longitudinally at the same distance in the same phase by adjusting positions of the shaft 27 and the pin 36. Hence, the wave making board 17 performs a piston type swinging. This eliminate deviation in the movement between the upper and lower parts of the wave making board to halve the number of motors and reduce the cost, thus facilitating the operation and maintenance.

Filed: 1987-02-02
Abstract: PURPOSE:To make it possible to use a heat accumulator in a heat pump and prevent the water leakage from a casing by installing in the casing the heat accumulator which is formed by filling into an elastic sealed vessel a high water containing gel substance. CONSTITUTION:In the inside of a casing 2 many heat accumulators 3 are provided in which a gel substance containing high proportion of water is filled and sealed in a plastic film as a vessel with elasticity. The cooling operation is carried out at night when the electricity cost is low in order to freeze the gel substance containing high proportion of water in the heat accumulator 3. And, during daytime the circulating water which is at high temperature by the heat exchange in an air conditioner 4 is sprayed from a water spraying section 8 on to the heat accumulator 3 to melt it and make cold water. This cold water is sent by a pump 9 from a cold water tank 5 to the air conditioner 4, where the heat is exchanged and then the water is sent back to the water spraying section 8. This cycle is repeated. The gel substance containing large proportion of water has its water content ratio at over 60% by weight and it excels in the shape holding property and mechanical strength, and PVA (polyvinyl alcohol) gel containing high proportion of water, for instance, which does not develop change in property or other performance deteriorations is used.

Title: Exhalation-component collection tube and its heating device
Inventor: YANAGIDA AKIRA
IPC: A61B5/083
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To shorten the analytical time, to enhance the handling property of a cylindrical body, and to expand the selectivity of the material and the structure of a collection-tube support by a method wherein a material through which microwaves can be transmitted is used for the cylindrical body and a heating element which generates heat by absorbing the microwaves exists so as to be mixed inside an adsorbent. SOLUTION: An exhalation A is passed through an exhalation-component collection tube 10, an exhalation component (a) is adsorbed, and the collection tube 10 is housed in a heating chamber. The heating chamber is irradiated with microwaves M by a microwave irradiation means. The microwaves M are transmitted through a cylindrical body 12, they are absorbed by a heating element 14 in an adsorbent 84 so as to generate heat, the adsorbent 84 is heated, and the exhalation component (a) is desorbed. The desorbed exhalation component (a) is guided to an analytical column together with a carrier gas. Since the heating element 14 is dispersed inside the adsorbent 84, the microwaves M are absorbed nearly uniformly in the adsorbent 84. Consequently, a temperature is raised at a nearly equal speed in the central part and the outer circumferential part of the adsorbent 84. In addition, since the microwaves M are transmitted through the cylindrical body 12, the cylindrical body is not heated by the microwaves M.

Title: Ink jet recorder
Inventor: MORIGUCHI HARUHIKO
IPC: H04N1/034
Filed: 1990-02-02
Abstract: PURPOSE:To obtain a high quality image stably at all time by performing drive control of a recording head in accordance with the receiving speed of an image signal. CONSTITUTION:Area A in the figure indicates optimal drive conditions and if a drive voltage drops below the area A, mainly a bubble generation power becomes short resulting in an unstable ink discharge. On the other hand, if the drive voltage rises above the area A, the temperature of an electric heating element increases excessively so that a bubble generation and decay process becomes unstable. Subsequently, an image is no longer stable and the temperature rises beyond the proper level resulting in the degradation of a voltage element. Therefore, for example, if a recording device is used in the printer mode and an image signal is set to a receiving frequency of 2kHz, the recording element is driven at a drive voltage of 15 to 18V. And if the device is used in the facsimile mode and the image signal is set to a receiving frequency of 0.1kHz, the recording element is driven at a drive voltage of 23 to 29V. A stable, high-quality recorded image can be obtained in the printer and facsimile modes by applying an optimal drive voltage to a recording head 11.

IPC: H02P1/16
Filed: 1980-02-25

Title: Acceleration sensor
Inventor: MORIYA SHIGERU
IPC: G01P15/09
Filed: 1988-02-02
Abstract: PURPOSE:To improve the detection accuracy and durability of an assembly by detecting displacement corresponding to the acceleration of a displaced body by a displacement signal detection part in a noncontact state, and converting it into a displacement signal indicating the acceleration and outputting the signal. CONSTITUTION:When the acceleration alpha operates on the body 2, the displaced body 12 is displaced accordingly and the gate bias of an FET varies owing to lines of electric force operating on an electrode part 16 at this time. Consequently, a displacement signal outputted from between terminals 17b and 17c becomes a signal of low frequency which varies in a sine wave shape corresponding to low-frequency acceleration. Thus, the displacement signal of low frequency outputted by a displacement detection part 6 is utilized for the vibration reduction of body springs and axle springs of a vehicle and optimum control over suspension characteristics. Namely, this acceleration sensor I detects the displacement of the displaced body 12 based upon the vertical acceleration alphaof the vehicle body in an irregular land travel to improve the contactness.
