Title: Semiconductor pressure transducer
Inventor: IBARA NOBUYUKI
IPC: G01L9/00
Filed: 1994-12-22
Abstract: PURPOSE: To make it possible to set working pressure readily by using a pressure sensitive element in the semiconductor sensor part of a pressure sensor, sensing the pressure, and making the threshold value formed by resistance voltage division variable. CONSTITUTION: A pressure sensor F, which uses, e.g. a piezoresistive pressure sensitive element as a semiconductor sensor part (a), is provided at the lower side of a signal processing printed circuit board 5, which is arranged in a main body 1 having pressure introducing ports A and B in two directions facing to each other up and down. A base part 3 of a resin stem 2 of the sensor F is sealed in the inner bottom part of the main body 1 with an O ring 6. The pressure, which is introduced through the introducing port A, is sensed by the sensor part (a) by way of the gap of the stem 2, the space formed in the main body 1 and the through hole of the base part 3. The pressure through the introducing port B is sensed by the sensor part (a) by way of a vertical hole 4 provided at the central part of the base part 3.  The pressure is transduced into the electric signal, and the signal is taken out with a terminal rod 8. The voltage of the electric signal is varied by a variable resistor, and the working pressure can be readily set. Furthermore, the simple mechanism as the pressure which is obtained at the low cost.

Title: Wheel speed control device for four-wheel-drive vehicle
Inventor: SHINOMIYA TAKASHI
IPC: B60T8/1763
Filed: 1989-12-08
Abstract: PURPOSE:To enhance reliability and safety of a control by additionally providing a correcting means which drops a control reference speed to the maximum actual wheel speed of the four wheels when the control reference speed exceeds the maximum actual wheel speed of the four wheels at the time of actuating a switch for detecting brake operation. CONSTITUTION:In a correcting means 4, when a detection signal of brake operation is received from a brake switch BSW, and when a control reference speed exceeds the maximum actual wheel speed of the four wheels, the control reference speed, used for judging a lock tendency, is corrected to the maximum actual wheel speed of the four wheels. When a drift condition is long continued, the control reference speed approaches the actual wheel speed. However, just as an accelerator is turned off, the actual wheel speed is quickly dropped. But when the switch BSW is turned on, because the above described correction is performed with the control reference speed set to the maximum actual wheel speed out of the four wheels, an antilock command, output from a lock condition detecting means 5 when the accelerator is turned off, is released simultaneously with operation start of a brake.

Abstract: PURPOSE: To efficiently observe an image at a low to medium magnification with an optical microscope and an image at a high magnification with an interatomic force microscope by placing a downsized interatomic force microscope probe between an objective lens and a sample to be observed. CONSTITUTION: A ceramic-tube-type scanning actuator 301 with 3-axes operation possible is attached in parallel with an objective lens 201 of an optical microscope to a microscope body attaching metal 202 of the lens 201, while an interatomic force detecting probe (cantilever) 101 downsized by making it a thin piezoelectric film or a piezo-resistor is attached at the tip of the actuator 301 to an attaching member 302 so that the tip of the probe comes into a field of view of the lens 201. This attaching member 302 has such a structure that the probe 301 can be moved in 3-axes directions. Since the probe 101 comprises the cantilever and a displacement detection system built into a single body, it can be downsized so that it can be put between the lens 201 and a sample 401 to be observed, while its weight can be so reduced that no burden is applied to the actuator 301.

Title: Photoreceptor drum and image forming device
Inventor: KIMOTO KEIZO
IPC: G03G21/00
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To uniformize the shaving of the surface of a drum, while improving cleaning performance by using a thing having a specific maximum drum runout width, as a photoreceptor drum. SOLUTION: Generally, the press-contact force of a cleaning blade 4 with a photoreceptive layer 3 is large at almost the center 5 of the blade 4 and smaller as it goes to both ends 6. Even in actual design, at the center 5 of the blade 4, sure contact is attained and the blade 4 whose rubber hardness is >=73 deg. is used with the arrangement of the contact. Then, in the drum 1, its maximum runout width satisfies the equation. Where, in the equation, (b) denotes the radius (mm) of the drum and 8 denotes an angle formed by a line X on the drum surface in parallel with a virtual center axis of the drum 1 and a contact tangent Y. Thus, the shaving quantity of a photoreceptor is even over the full surface of the drum 1, while the cleaning performance is sufficiently improved. Consequently, a stable image can be formed over a long period.

Inventor: SAKANO TAKESHI
IPC: C01G15/00
Filed: 1987-12-18
Abstract: PURPOSE:To remove metallic impurities and obtain an aqueous solution of high-purity In salts, by regulating the aqueous solution of the In salts to a specific pH and adding a compound of N-nitrosohydroxylamines having an aromatic substituent group to the adjusted aqueous solution. CONSTITUTION:An aqueous solution of In salts is adjusted a pH within the range of 0.5-2.5. A compound of N-nitrosohydroxylamines having an aromatic substituent group is then added to the adjusted aqueous solution to separate accompanying heavy metallic impurities as sparingly soluble salts. N- nitrosophenylhydroxylamine, N-nitrosonaphthylhydroxylamine, etc., are cited as the N-nitrosohydroxylamine having the aromatic substituent group for use. If the pH is lower than 0.5, removal ratio of the impurities is considerably reduced. If the pH exceeds 2.5, indium is precipitated in a certain form and there is a fear of increasing loss. The most preferred pH is within the range of 1-2.

The blocking piece 15 is almost uniform in thickness, however, a cut area where the thickness is linearly small may be provided in the middle of the blocking piece 15, therefore the slim tubular containers 13 and 14 can be separated without being opened. Also, it is possible to provide joints between the blocking piece 15 and the slim tubular containers 13 and 14 with a cut or a cut area where the thickness is linearly small. This makes it possible to separate the slim tubular containers 13 and 14 and to open either one of the slim tubular containers 13 and 14 or both.
